More Than a Product Claim: Evidence You Can Check

Certification standards and independent test reports help customers understand what a filtration product has actually been evaluated for. Instead of relying only on packaging, advertising, or marketplace descriptions, you can review the applicable standard, product model, tested claim, and supporting documentation.

Documentation Across Purewell Filtration Products Purewell filtration systems and replacement filters are supported by corresponding certification and/or test documentation. Customers can review system documents, filter documents, and performance reports through the Purewell Test Reports page.

Verifiable Evidence

NSF/ANSI 42

Drinking Water Treatment Units — Aesthetic Effects

What Does It Mean in Everyday Language?

This standard evaluates drinking-water treatment products for specified effects that influence the appearance, taste, smell, or everyday drinking experience of water.

Chlorine reduction, when listed

Taste and odor reduction, when listed

Particulate reduction, when listed

Materials, construction, and performance requirements

Certification Is Claim-Specific NSF/ANSI 42 does not automatically mean that a product reduces every contaminant. Check the certificate or listing for the exact model and certified reduction claims.

372

NSF/ANSI/CAN 372

Drinking Water System Components — Lead Content

What Does It Mean in Everyday Language?

This standard evaluates the lead content of materials and components that come into contact with drinking water, using defined calculations and verification procedures.

Evaluates wetted product components

Verifies applicable lead-content limits

Reviews materials used in the water pathway

Supports lead-content compliance verification

Lead Content Is Not Lead Reduction NSF/ANSI/CAN 372 evaluates lead content in product materials. It does not by itself certify that a filter removes lead already present in the source water.

From a Marketing Claim to Verifiable Evidence

Reliable documentation connects a standard to an identifiable product, a defined test scope, and a report or certificate that customers can review.

Identify the Standard Confirm whether the document refers to NSF/ANSI 42, NSF/ANSI/CAN 372, or another applicable standard.

Match the Product Check that the brand, product type, component, or model matches the item being sold.

Read the Test Scope Review exactly what was evaluated, including the reduction claim, material requirement, test condition, or performance category.

Review the Evidence Open the certificate, listing, or laboratory report instead of relying only on a badge or unsupported product description.

Product with Verifiable Documentation Claims can be checked against supporting evidence.

The applicable product or component can be identified.
The meaning and scope of the standard can be reviewed.
Specific performance claims can be checked against a report.
Customers can distinguish certification from general testing.
Material and performance claims have a documented basis.

Documentation does not mean every possible contaminant has been tested. It provides evidence for the specific scope shown in the applicable certificate or report.

Product Without Accessible Evidence Important claims may be difficult to confirm.

A standard logo may appear without a matching certificate.
The tested model may differ from the product being purchased.
Broad removal claims may exceed the actual test scope.
Lead-content compliance may be unclear or undocumented.
Customers may be unable to verify the source or date of a report.

An unavailable report does not automatically prove that a product is unsafe. However, it prevents customers from independently confirming the advertised certification and performance claims.

Documentation Available from Purewell

Purewell organizes supporting documents by system, filter, standard, and filtration performance so customers can review the evidence relevant to their product.

Filter System Documents Certification or test documentation associated with applicable complete filtration-system components.

Replacement Filter Documents Supporting documentation associated with applicable Purewell replacement filters and filter elements.

Performance Test Reports Laboratory reports covering specified filtration-performance categories under defined test conditions.

Customer-Accessible Files Downloadable documents provide more transparency than a badge, short claim, or marketplace product description alone.

Important Certification Notes

Reading the standard correctly is as important as seeing the certification or test badge.

Check the Exact Product or Component Certification and test results should be matched to the applicable product, filter, component, model, or documented product family.

Check the Exact Certified Claim A product certified under NSF/ANSI 42 may support only the reduction claims specifically shown in its certificate or listing.

372 Does Not Mean Lead Removal NSF/ANSI/CAN 372 concerns lead content in wetted materials. Lead reduction from source water requires a separate applicable filtration-performance claim.

Certification and Testing Are Different A certification, a component certification, and an independent laboratory test report are different forms of evidence and should be described accurately.

Review Test Conditions Results may depend on source-water conditions, flow rate, capacity, product setup, test protocol, and filter condition.

Replace Filters as Directed Certification or testing does not make a filter permanent. Follow the applicable installation, flushing, use, and replacement instructions.

Pressure-Driven Reverse Osmosis Technology

A Selective Membrane Designed to Reduce Dissolved Solids

A reverse osmosis membrane uses pressure and selective separation to divide incoming water into two streams. Water that passes through the membrane becomes the purified-water stream, while many rejected dissolved substances leave through a separate concentrated-water outlet.

Standard Composite RO Cartridge The K8680 combines activated carbon and a reverse osmosis membrane inside its standard composite cartridge. The RO membrane is part of the main filtration construction rather than an optional add-on.

Water passes through the selective membrane layer

Rejected dissolved substances leave with concentrated water

How Reverse Osmosis Works

Reverse osmosis is not simple particle screening. The system uses pump pressure to move pretreated water across a selective membrane and separate the purified-water stream from the concentrated-water stream.

Water Is Pretreated The intake pre-filter and activated carbon stages help reduce sediment, debris, chlorine-related characteristics, taste, and odor before water reaches the RO membrane.

The Pump Creates Operating Pressure The electric pump provides the pressure required to move source water toward and across the reverse osmosis membrane.

Water Contacts the Selective Membrane The membrane allows water to move into the purified-water pathway while restricting many dissolved salts, ions, and other membrane-rejected substances.

Purified Water Passes Through Water that passes through the membrane is called permeate and is directed toward the blue PURE water outlet.

Concentrated Water Is Separated Rejected dissolved substances remain in the concentrated water stream, which leaves the system through the red DIRTY water outlet.

Helps Reduce TDS Reverse osmosis is designed to reduce many dissolved substances that contribute to total dissolved solids.

Selective Separation The membrane separates water from many dissolved salts, minerals, ions, and other membrane-rejected substances.

Separate Water Streams Purified water and concentrated water leave through separate outlets instead of remaining mixed together.

Works with Multiple Stages The RO membrane works together with pre-filtration, activated carbon, TDS monitoring, and UV treatment in the K8680 system.

✓ Designed to Help Reduce

Total dissolved solids in source water
Many dissolved salts and mineral ions
Certain dissolved metals and inorganic substances
Selected contaminants rejected by the membrane
Differences between raw-water and purified-water TDS

i Understand the Filtration Limit

Does not reduce every substance at the same rate
Does not eliminate the need for pre-filtration
Requires suitable pressure and operating conditions
Produces a separate concentrated-water stream
Is not intended for seawater or industrial wastewater

Important Use and Care Notes

Correct preparation, source-water selection, flushing, and timely cartridge replacement help maintain membrane performance.

Complete the Initial Flush Flush the system before drinking from it for the first time. Discard the initial water until it runs clear and the system completes its cleaning cycle.

Protect the Membrane with Pre-Filtration Keep the intake pre-filter and medical PP cotton clean. Excess sediment can reduce water flow and place additional load on the RO cartridge.

Use Within the Temperature Range Use source water between 41°F and 100°F / 5°C and 38°C. Do not use hot water or allow the system to freeze.

Monitor Purified-Water TDS Compare raw-water and purified-water TDS readings. A consistently elevated purified-water reading may indicate reduced membrane performance.

Replace the Cartridge When Needed Replace the composite RO cartridge when its rated life is reached or when water flow, taste, odor, or TDS performance noticeably declines.

Store the System Correctly For long-term storage, drain the system, remove the filters, allow the components to dry, and store them in a cool, dry location.

Reverse osmosis performance depends on source-water TDS, temperature, pump pressure, membrane condition, flow rate, maintenance, and product design. The K8680 specification lists a 95% desalination rate under rated conditions. Actual results may vary. Specific contaminant-reduction statements should be based on the applicable Purewell product specifications and test reports.

Silver Ion Bacteriostatic Support

Built-In Protection for the Filter Media

Silver-ion-treated media is designed to help inhibit bacterial growth within the filter material. It supports filter-media hygiene between uses while working alongside the system’s primary filtration technologies.

Standard Silver-Ion-Treated Filter Media Where silver-ion-treated media is listed in the product specification, it is included as part of the standard Purewell filter construction—not offered only as an optional upgrade.

Purewell Standard

Protection Within the Filter Media

Water Enters the Filter

Water Continues to the Next Stage

Ag+

Silver ions are integrated into the treated filter media

Helps inhibit bacterial multiplication within the media

Supports the filter material—it is not a standalone water disinfectant

How Silver Ion Support Works

Silver ions are incorporated into selected filtration media to provide bacteriostatic support inside the cartridge.

Silver Ions Are Integrated into the Media The silver-ion component is distributed within or applied to the selected filter material during manufacturing.

Water Contacts the Treated Surface As water moves through the cartridge, it contacts the silver-ion-treated filtration media.

Growth Within the Media Is Inhibited The silver-ion treatment helps limit bacterial multiplication on or within the filter material during normal use.

Primary Filtration Stages Continue the Work Carbon, ceramic, UF, or other specified filtration stages perform the system’s primary contaminant-reduction functions.

Bacteriostatic Does Not Mean Sterilizing Silver-ion-treated media is intended to help control growth inside the filter. It should not be presented as proof that bacteria, viruses, or other microorganisms have been removed from the source water.

Helps Inhibit Growth Supports control of bacterial growth within the treated filtration material during normal product use.

Supports Filter-Media Hygiene Helps manage microbial activity inside the filter material rather than serving as the system’s primary filtration barrier.

Integrated into the Cartridge The treated material is built into applicable Purewell filters and does not require the user to add a separate treatment chemical.

Complements Other Media Works alongside activated carbon, ceramic, UF, or other specified filtration materials in a multi-stage filter design.

✓ Designed to Support

Bacteriostatic protection within treated filter media
Control of bacterial multiplication inside the cartridge
Filter-media hygiene during normal product use
Multi-stage filtration when paired with other media

i Not Intended to Replace

A validated microbiological filtration barrier
Boiling, disinfection, or official boil-water guidance
UF, RO, UV, or other specified treatment technologies
Timely cleaning, flushing, and filter replacement

Important Use and Care Notes

Silver-ion support does not replace correct filter preparation, maintenance, or appropriate source-water selection.

Flush Before First Use Prepare and flush the filter according to the product instructions before using the filtered water for drinking.

Use an Appropriate Water Source Silver-ion-treated media alone does not make sewage, industrially polluted water, saltwater, or other unsafe sources suitable for drinking.

Do Not Open or Modify the Filter Do not remove, add, regenerate, or alter the internal filter media. Use the cartridge only in its original configuration.

Replace the Filter on Schedule Bacteriostatic support does not make a filter permanent. Replace it when the rated capacity or recommended service period is reached.

Avoid Hot Water and Chemicals Do not use hot water, bleach, detergents, or treatment chemicals unless they are specifically permitted in the product instructions.

Avoid Extended Water Stagnation Follow the recommended flushing and storage procedure after extended periods of non-use or when water has remained inside the system.

Follow Public Health Advisories During a boil-water notice or known microbiological event, follow instructions from the relevant local health authority.

Check the Product Specification Silver-ion content, media type, intended use, and performance claims may vary between Purewell filter models.

Silver-ion-treated media is intended to help inhibit bacterial growth within the filter material. It is not a standalone disinfectant and does not by itself establish that source-water microorganisms have been removed. Performance depends on the media formulation, product design, water quality, operating conditions, maintenance, and timely replacement. Refer to the applicable Purewell product specifications and test information for model-specific claims.

Activated Carbon Adsorption Technology

Porous Carbon Designed to Improve Water Taste and Odor

Activated carbon contains a network of microscopic pores that creates a large internal surface area. As water moves through the media, certain compounds are attracted to and held on the carbon surface through a process known as adsorption.

Standard Activated Carbon Filtration Media Where activated carbon is listed in the product specification, it is included as part of the standard Purewell filter construction rather than offered only as an optional upgrade.

Purewell Standard

Adsorption Inside the Carbon Media

Incoming Water

Water Flows Out

Water carries chlorine, taste, odor, and certain organic compounds

Certain compounds are held within the porous carbon surface

Water continues through the filtration system

How Activated Carbon Works

Activated carbon primarily works through adsorption. Compounds are attracted to the carbon surface instead of simply being screened out by pore size.

Water Enters the Carbon Media Source water flows around and between the activated carbon particles inside the filter.

Water Contacts the Porous Surface Microscopic pores provide a large internal surface area for water and dissolved compounds to contact.

Certain Compounds Are Adsorbed Chlorine, taste-and-odor compounds, and certain organic substances may be attracted to and held on the carbon surface.

Water Continues Through the Filter After contacting the carbon media, water moves to the next filtration stage or exits the system, depending on the filter design.

Improves Taste and Odor Helps reduce compounds that can create unwanted tastes or odors in drinking water.

Helps Reduce Chlorine Activated carbon is commonly used to help reduce chlorine taste and odor in treated municipal water.

High Internal Surface Area A network of microscopic pores creates extensive contact area within a compact amount of filter media.

No Treatment Chemicals Added Activated carbon performs through surface adsorption and does not require chemicals to be added to the water.

✓ Designed to Help Reduce

Chlorine taste and odor
Unpleasant tastes and smells
Certain volatile organic compounds
Certain adsorption-sensitive organic substances

i Understand the Filtration Limit

Does not normally reduce dissolved salts or TDS
Does not soften hard water by itself
Is not a complete microbiological barrier on its own
Does not reduce every contaminant without additional media

Important Use and Care Notes

Correct preparation and timely replacement help maintain adsorption performance and water quality.

Flush Before First Use Flush the filter according to the product instructions before drinking. This helps remove loose carbon fines and trapped air.

Temporary Carbon Fines May Appear A small amount of dark carbon dust may appear during initial rinsing. Continue flushing until the water runs clear.

Use Within the Recommended Temperature Range Do not use hot water unless the specific product instructions state that the filter is designed for hot-water use.

Use with an Appropriate Water Source Activated carbon alone does not make microbiologically unsafe, industrially polluted, or saltwater sources suitable for drinking.

Replace the Filter on Schedule Adsorption sites gradually become occupied. Replace the filter when its rated life is reached or when taste and odor reduction noticeably declines.

Follow Storage Instructions Clean and store the filter as directed when the system will not be used for an extended period. Do not leave stagnant water in the system longer than recommended.

Filtration performance depends on the activated carbon type, carbon quantity, contact time, water quality, flow rate, product design, and maintenance. Specific contaminant-reduction claims should be based on the applicable Purewell product specifications and test results.

How It Works

Working Principle

How the Portable RO Water Filter System Works

The system draws source water through the white RAW water line, moves it through multiple filtration and treatment components, separates purified water from concentrated drain water, and sends each water stream to its corresponding outlet.

Water Treatment Path From Source Water to Purified Water

Input General Outdoor Freshwater

Source water enters through the white RAW pipe and intake pre-filter.

Raw Water TDS

Pure Water TDS

Intake Pre-Filtration Stainless steel mesh and medical PP cotton help capture larger debris, sediment, rust, and suspended particles.

Activated Carbon Treatment Helps reduce chlorine, color, unpleasant taste, odor, and selected organic substances.

Reverse Osmosis Separation The RO membrane separates purified water from dissolved solids and concentrated drain water.

UV Treatment Built-in UV treatment provides an additional stage targeting bacteria and viruses during operation.

Blue PURE Outlet Purified Water

Sent to the faucet or a clean water collection container.

Red DIRTY Outlet Concentrated Water

Directed away from the system through the drain-water pipe.

White · RAW Blue · PURE Red · DIRTY

Draw Water Through the RAW Inlet

The electric pump draws source water through the intake pre-filter and white RAW water pipe. The intake pre-filter helps prevent larger outdoor debris from entering the system.

Complete Pre-Filtration and Carbon Treatment

Medical PP cotton helps capture sediment and fine particles. Activated carbon then helps improve water color, taste, odor, and chlorine-related characteristics.

Separate Water Through the RO Membrane

Pressure moves the pretreated water through the reverse osmosis membrane. Purified water passes through the membrane, while concentrated water is directed toward the DIRTY outlet.

Apply UV Treatment

The built-in UV system operates as an additional treatment stage while water is being produced. The UV indicator shows its operating status on the control display.

Monitor Raw and Purified Water TDS

The display shows the TDS level of both the incoming source water and the purified water, helping users monitor changes in system performance.

Collect Pure Water and Drain Concentrated Water

Purified water exits through the blue PURE line for collection. Concentrated water exits separately through the red DIRTY line and should be directed to a suitable drainage location.

Automatic cleaning: When the purifier is powered on, the system begins an automatic flushing process. Wait until the flushing indicator turns off before evaluating normal water production.

System Type Pump-Driven Portable RO System

Uses electric pressure instead of gravity alone.

Main Treatment Path Pre-Filter + Carbon + RO + UV

Groups the primary functional components of the system.

Water Quality Display Raw TDS & Pure TDS

Displays incoming and purified-water TDS readings.

Separate Outputs PURE Water + DIRTY Water

Purified and concentrated water leave through separate pipes.

Filtration-stage note: The product manual identifies the complete K8680 system as a 10-stage filtration system. For easier customer understanding, this working-principle module groups those stages into the main functional components: intake pre-filtration, activated carbon, reverse osmosis, and UV treatment.

Water source notice: The system is designed for general outdoor freshwater sources. It is not intended for seawater, industrial wastewater, chemically contaminated water, or water outside the recommended operating range.

Filter Replacement

K8680 Filter Replacement & Maintenance Guide

Regular cleaning and timely filter replacement help maintain water flow, purified-water TDS performance, drinking water taste, and long-term reliability of your Portable RO Water Filter System.

Track Capacity, Time & TDS

Actual filter life varies according to source-water quality, sediment load, TDS level, filtered volume, and maintenance.

Purified-Water TDS Stays High

Consistently elevated purified-water TDS may indicate reduced pre-filter or RO membrane performance.

Water Flow Becomes Slower

Reduced flow may be caused by a blocked pre-filter, saturated PP cotton, or an aging RO cartridge.

Taste or Odor Changes

Replace the cartridge when unwanted taste or odor returns after normal flushing and cleaning.

Rated Capacity or Time Is Reached

Use both filtered-water volume and recommended replacement intervals when planning maintenance.

K8680 Filter Components

The K8680 uses an intake pre-filter, replaceable PP cotton, a composite RO cartridge containing activated carbon and an RO membrane, plus a built-in UV treatment module.

Intake Pre-Filter

How to Replace the Composite RO Cartridge

Turn off the system and disconnect the water supply before opening the cartridge compartment. A small amount of residual water during replacement is normal.

01 Turn Off the System

Stop filtration, turn off the main power, and disconnect the water supply before replacement.

02 Unlock the Top Cover

Rotate the top cover to the unlocked position and lift the upper panel carefully.

03 Remove the Used Cartridge

Hold the cartridge handle and pull the cartridge vertically upward without twisting the internal connection.

04 Install the New Cartridge

Remove the protective film, align the three slots at the bottom, and push down until the cartridge is securely seated.

05 Flush Before Drinking

Close the upper panel, reconnect the pipes, and run the system for approximately 30–60 seconds to rinse the RO membrane.

Installation reminder: Make sure the cartridge is fully aligned with the three bottom connection points. Do not force the cartridge or operate the system when the cartridge is not completely seated.

How to Use TDS Readings

The front display shows both raw-water TDS and purified-water TDS. Use the purified-water reading as a performance trend rather than judging the cartridge from one isolated reading.

Correct Testing Method Run Water for 1–2 Minutes

Collect purified water from the blue PURE outlet in a clean container. Small fluctuations are normal; consistently elevated readings are more useful for maintenance decisions.

Below 50 ppm Excellent

Listed in the manual as an ideal purified-water TDS range.

50–100 ppm Typical RO Range

May be acceptable depending on the original source-water TDS.

Below 200 ppm Acceptable Reference

Continue monitoring the reading and compare it with raw water.

Consistently Above 200 ppm Inspect the Filters

Clean the pre-filter and consider PP cotton or RO cartridge replacement if performance remains reduced.

Maintenance Before Replacing Filters

Clean the Intake Pre-Filter

Rinse or backflush the stainless steel pre-filter monthly to reduce blockage caused by outdoor debris.

Check All Three Pipes

Make sure the white RAW, blue PURE, and red DIRTY pipes are correctly connected without sharp bends or obstruction.

Check the Source Water

Heavy sediment, high TDS, or visibly dirty source water may shorten PP cotton and RO cartridge life.

Run the Automatic Flush

Allow the automatic cleaning process to finish after the system is powered on before evaluating normal water production.

Record Replacement Dates

Track the installation date, filtered-water volume, and typical purified-water TDS for each new cartridge.

Store the System Dry

For long-term storage, drain the system, remove the filters, air-dry all components, and keep them in a cool, dry place.

Surprisingly effective..!!!

Tested my tap water which read 376 ppm then ran the same water source thru the system and tested it again post filtration and read 15ppm. Was shockingly surprised at the results and very happy. Would like the hose material to be more flexible but I can live with it.

Water produced tastes good and has no oder.

Works better than any purifier I've ever had. I can filter the most murky, moss covered water and it comes out pure and clean with no foul taste or oder. It like getting bottled water from the store. Takes about 30 minutes to produce a gallon, but is well worth the wait. Produces approximately 10 gallon fully charged.

I got the orange one, love it.

I will be using it this weekend on a camping trip in my new minimalist camper/ off road vehicle. Everyone who is going is so jealous as they have to cart in water and I will just make mine creek side. I see more sales in the future for the purewell. Ps don’t sell them any orange ones. Just kidding.

My rainwater taste great!

The machine works as it should. Mine will be used on my homestead to supply my drinking water from rainwater. I filled 8 gallons, at about 10 minutes per gallon. The battery showed no decrease, and the water tasted great. I wish the USB-C port cover was attached to the machine. I think I have lost it already. It seems to waste a lot of water through the dirty water outlet. I will measure it next time, but I would say it is almost 1 gallon of drinking water to 1 gallon of dirty wastewater. In a place where I live off summer monsoons and occasional winter snowstorms, it seems like a huge waste of a precious resource.

I’ve been using it for 3 months, it always works well. The filtered water never let me down!

Very good and durable

This product worked as expected. It is compact and lightweight. Even it come with survival compass and a floodlight! Would recommend

Awesome mobile RO unit

This unit makes a gallon of filtered water in less than fifteen minutes.
This review is also to acknowledge the awesome support we received after we purchased this RO. When it arrived it was missing the three tubbings and there was a crack on the screen. Things happen and I appreciate the service provided. The service was prompt and taken care of. I would order from this company again. Thank you for standing behind your product.

Worth it

I live in an area with high TDS in the water. After a week with this purifier, I can definitely taste the difference. Feels safer giving this water to my kids.

Won’t Leave Home Without It

This thing is a game-changer. Water comes out tasting fresh every time, and it’s built solid. I keep it in my truck, and honestly, I wouldn’t head out without it.

Clean Water Anywhere

I take this RO water purifier on all my camping trips now. Super easy to use, and the water tastes clean every time. I’ve used it with lake water and river water — no weird taste, no stomach issues. It’s light to carry, and it filters faster than I expected. Feels solid, not cheap. Definitely worth it for anyone spending time outdoors.

Reliable and Fully Prepared Water Purifier for Emergency Use

I chose this product from a brand I personally trust for emergency preparedness. The best part is how everything fits snugly in a dedicated carrying bag, making it easy to store and transport. You can keep it with your other survival gear unused, and it’s ready when needed in an emergency. The manual is included, so it’s clear what to do, and all parts are neatly organized. The unit is very compact, yet it is designed with a reverse osmosis system for producing drinking water. The three extension tubes are stored in a pocket at the bottom of the bag (in the unit I received), and many might overlook them, so be sure to check carefully.

The replacement filter is expensive; however, it may last 1–3 years depending on water quality, which gives peace of mind that, with just one extra filter (purchased separately) on hand, you’re better prepared to handle a wide range of survival scenarios.

One note: the filter cap with the compass is quite tight, so I recommend adding a pair of non-slip gloves or a piece of grippy cloth into the bag. That way, this set alone feels sufficient for producing drinking water in case of emergency.

Perfect for temporary or emergency situations!

While being kind of a Niche, this RO system is a great prepping tool. Now, nothing beats water storage, but what happens when that water supply you thought was good is actually contaminated? That's where RO comes in. The membranes filter TDS (total dissolved solids) from water by having holes too slamm for particles to pass through, except water. This is battery powered so don't expect a daily supply of water. But if your power is out or supply is bad, you can use this to filter river or pond water. Theoretically this will desalinate sea water, but I wouldnt use it for that as the internals are probably not rates for salt.

This will reduce your TDS to under 50ppm which is considered safe for consumption. Actually very clean water. Just know that this also removes minerals, so you will need them from another source if you primarily drink RO water.

You can test the water with a TDS meter, and monitor the membrane quality. It is always recommended to build your water if it's from a natural source (river pons creek ECT). But as a last resort or emergency this would suffice alone. Boiling and using this machine? You have better water than 98% of people on earth.

The faucet is nice and this would be a great unit for say a hunting cabin, or RV/camper. But my purpose is prepping, and this unit is perfect for my needs. I already have a RO system in my home and I just can't go back to city water now that I've tasted the RO water!

Great for the emergency stash.

My husband has been playing with this and he says it works well. It's excellent for an emergency, provided you have a power source. Our generator ran it just fine. The water tasted fantastic as well.

Clean water!

After the 2024 hurricane season I knew I needed a way to make sure my family always had access to fresh water. This portable RO water filter is AMAZING. It's rechargeable, but you can also use it while plugged in. It's truly portable--everything you need is in a zippered bag, and they've even gone the extra mile and made it organized. The instructions are so clear and it's surprisingly easy to use. The peace of mind is so worth the cost!

Compact, Powerful, and Reliable Water Purifier – Exceeded Expectations

I’ll admit I was skeptical about this unit at first, having had mixed results with other water purifiers in the past. However, the Purewell® K8680 RO Water Purifier System really impressed me right out of the box. What stands out is its compact and portable design—it’s lightweight, battery-powered, and built to travel, yet it doesn’t sacrifice performance.

The purification speed is surprisingly fast for such a small unit. In my initial tests, it took my tap water from 150–160 ppm total dissolved solids all the way down to under 10 ppm, with some readings as low as 004 ppm. That’s remarkable. I also appreciate the added peace of mind with the built-in UV sterilization light, which adds an extra layer of protection.

The battery life is equally impressive. Even after purifying several gallons of water, the battery level hardly dropped, and recharging is easy with the included USB-C cable and plug. For camping, RV travel, or even emergency preparedness, this is an outstanding piece of survival gear.

Highly recommended for anyone looking for a reliable, portable, and effective water purification solution.

Perfect EMERGENCY KIT Water Purifier!

Living in hurricane alley, we have to always be on-guard for disasters! This water purifying kit is a wonderful item to have in your emergency kit! It is simple to use, it's portable and it also is a charging station, flashlight and compass. This has everything going for it! I would highly recommend this water purifier system, especially for anyone living in danger zones. (Which seems just about everybody these days!)

Surprisingly effective..!!!

Water produced tastes good and has no oder.

My rainwater taste great!

Nice product!

I use this filter for the water that was cloudy, smelly and full of floating debris. It turns the water into clean, great-tasting water! Hoping it’s reliable—it’s a perfect simple solution for emergencies and health needs, way better than other options. Ultra portable (fits in a backpack for bug-outs) and easy to charge via USB-C. No downsides at all!
