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.

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.

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.

How It Works

How the C01 Countertop RO System Works

The C01 draws municipal tap water from its removable feed-water tank, processes it through a two-filter reverse osmosis system, stores purified water inside the matching pitcher, and heats the water to the selected temperature when it is dispensed.

C01 Water Process From Tap Water to Ready-to-Dispense RO Water

4.5L

Feed Water Municipal Tap Water Enters the Removable Tank

The countertop design requires no permanent plumbing or direct faucet connection.

Main Purification Activated Carbon and RO Composite Filtration

The main cartridge pre-treats the water and performs high-precision reverse osmosis separation.

Purified Stream RO-Filtered Water Moves Forward

Concentrated Stream Separated Water Remains in the Feed Tank

Final Treatment Activated Carbon and Mineral Post-Filtration

The second cartridge provides final treatment to help refine the taste of the RO-filtered water.

1.4L

Automatic Storage Purified Water Collects in the Matching Pitcher

The system automatically produces water when the pitcher level is low and stops when it is full.

HOT

Instant Dispensing Select the Desired Volume and Temperature

Water is heated during dispensing and delivered through the outlet at the selected setting.

Important: Do not add fresh water directly on top of the remaining concentrated water. Empty the feed-water tank before refilling.

Fill the Removable Feed-Water Tank

Remove the rear tank, add municipal tap water without exceeding the maximum level, and return the tank securely to the appliance. No plumbing installation is required.

Water Passes Through the Main RO Composite Filter

The system draws water through the activated-carbon and reverse osmosis composite cartridge. This stage helps pre-treat the water and reduce dissolved solids and other unwanted substances.

RO Filtration Separates Two Water Streams

The reverse osmosis process separates the purified-water stream from the concentrated-water stream. The concentrated water remains inside the removable feed-water tank.

Purified Water Receives Final Post-Filtration

After RO separation, the purified water passes through the activated-carbon and mineral post-filter to help refine its final taste and drinking characteristics.

The Pure-Water Pitcher Refills Automatically

When the water level inside the matching 1.4-liter pitcher becomes low, the system automatically starts producing purified water and stops once the pitcher reaches its full level.

Water Is Heated and Dispensed on Demand

Select 120 mL, 250 mL, 500 mL, or 999 mL, adjust the desired water temperature, and press the water-output button. The C01 heats the stored purified water during dispensing.

The Smart Panel Monitors System Status

The display provides the TDS value, filter-life status, pitcher-position indicator, water-production status, and reminders to replace the water inside the feed tank.

TDS display notice: The final post-filter may add selected minerals to the purified water. Therefore, the displayed TDS value should not be used by itself to evaluate contaminant-reduction performance.

Water-changing reminder: Empty and refill the feed-water tank when the change-water indicator flashes, when the remaining water reaches the minimum level, after the tank has been moved, or when the water has remained inside for more than 48 hours.

Filter Replacement

C01 Filter Replacement Guide

Replacing both C01 filter cartridges at the appropriate time helps maintain stable RO water production, effective filtration, fresh water taste, and reliable everyday system performance.

Monitor the PR and C Indicators

The C01 display monitors both filter cartridges separately. Check the PR indicator for the main RO cartridge and the C indicator for the activated-carbon post-filter.

Steady White Indicator

A steady white PR or C indicator means the monitored filter life remains above 10%.

Flashing Red Indicator

A flashing red indicator means the monitored filter has less than 10% of its estimated life remaining.

Steady Red Indicator

A steady red PR or C indicator means the corresponding filter has reached the end of its monitored service life.

Water Production Becomes Slower

Reduced production speed may indicate filter blockage, scale buildup, cold feed water, or poor source-water quality.

Water Taste or Odor Changes

A noticeable change in taste or odor may indicate that the main filter or post-filter requires replacement.

Recommended Time Is Reached

Follow the recommended replacement period even when the system continues to produce water normally.

C01 Replacement Filter Configuration

The C01 uses two independently monitored filter cartridges. Both filters are installed inside the front filter compartment of the countertop system.

PR Main System Filter

Activated Carbon + RO Composite Filter

The main PR cartridge combines activated-carbon pretreatment with reverse osmosis filtration to support dissolved-solids reduction and high-precision water purification.

Recommended Life Approximately 12 Months

Display Indicator PR

Replacement Method Twist to Unlock and Lock

After Replacement Reset and Flush Required

C / ACF Post-Filter

Activated Carbon Alkaline Post-Filter

The second-stage post-filter provides final activated-carbon treatment and helps refine the taste and drinking characteristics of RO-filtered water.

Recommended Life Approximately 6 Months

Display Indicator C

Replacement Method Pull Out and Push In

After Replacement Reset and Flush Required

Before Replacing a C01 Filter

Stop Water Production

Wait until the system has finished producing water or performing an automatic flushing cycle.

Disconnect the Power

Turn off and unplug the C01 before opening the filter compartment or removing either cartridge.

Prepare for Residual Water

A small amount of water may remain inside the used filter and drain during removal.

Use the Correct Filter

Install replacement cartridges specifically designed for the Purewell C01 countertop RO system.

Check the Installation Position

Make sure the cartridge is aligned correctly and is fully inserted before reconnecting the power.

Prepare for Flushing

Keep the feed-water tank and purified-water pitcher clean and correctly installed for the flushing process.

PR Main RO Filter Replacement Steps

Follow these steps when replacing the activated-carbon and reverse-osmosis composite cartridge monitored by the PR indicator.

Remove the Filter Cover

Pull the filter cover from the bottom to access both cartridges inside the front compartment.

Unlock the Used PR Filter

Hold the cartridge handle and rotate the filter counterclockwise to the unlocked position.

Remove and Replace the Filter

Pull the used cartridge toward you, then insert the new PR filter into the same connection.

Rotate the New Filter to Lock

Turn the new cartridge clockwise until it reaches the marked locked position, then reinstall the filter cover.

C / ACF Post-Filter Replacement Steps

The second-stage post-filter uses a direct pull-out and push-in replacement design rather than a twist-lock connection.

Open the Filter Compartment

Disconnect the power supply and remove the front filter cover to access the post-filter.

Pull Out the Used Post-Filter

Hold the old cartridge securely and pull it straight out. Some force may be required.

Align the New Cartridge

Match the end faces and connection position of the new filter with the original installation direction.

Press Firmly into Position

Push the new post-filter fully into place, reinstall the cover, and reconnect the power supply.

Reset the PR or C Filter-Life Indicator

Reset only the indicator that corresponds to the filter you have replaced.

Step 1 Press and hold the 250 mL and 500 mL buttons together for 3 seconds. The system will beep and the PR indicator will begin flashing.

Step 2 Short-press the 250 mL button to switch between the PR and C indicators. Stop when the replaced filter’s indicator is flashing.

Step 3 Press and hold the 250 mL and 500 mL buttons together again for 3 seconds. Two short beeps confirm that the selected filter has been reset.

Replacement and Flushing Checklist

Filter or Process	Recommended Timing	Display or Replacement Signal	Required Action
PR Activated Carbon + RO Composite Filter	About 12 Months	PR flashes red below 10% remaining life and stays red when the monitored life has expired.	Replace the twist-lock cartridge, reset PR, and complete the required flushing process.
C / ACF Activated Carbon Post-Filter	About 6 Months	C flashes red below 10% remaining life and stays red when the monitored life has expired.	Pull out the used filter, push in the replacement, reset C, and flush the system.
New-Filter Flushing	After Replacement	Required after installing either new filter cartridge.	Process and discard water until approximately five full feed-water tanks have been completed.
Filter-Life Reset	Every Replacement	The newly installed filter will not be tracked correctly until its PR or C indicator has been reset.	Select the correct indicator using the 250 mL button, then confirm the reset with the 250 mL and 500 mL buttons.

Filter-life reminder: The recommended 12-month and 6-month replacement periods are reference values. Source-water quality, hardness, TDS, temperature, daily consumption, filtered volume, maintenance, and local conditions may shorten or extend actual filter life.

Important: Do not drink water produced during the new-filter flushing process. The first batches may look white or cloudy because of tiny air bubbles inside the new filter. Continue flushing and discard the produced water until the required process is complete.

Purewell® Countertop Reverse Osmosis Water Purification System, Alkaline Water Filter with Portable Water Pitcher, NSF 58 Certified Elements-C01

Nice water filter

It is a awesome product

Under Sink RO Altenative Unit

This was easy to set-up, just follow the instructions in the booklet provided. As of right now water quality is great. I have only had it setup for a day. This will be better than lugging 3 gallon water bottles up two flights of stairs. Since I live in an apartment with quartz counter tops and no useable hole around the sink this is a great alterintive than a under the sink RO unit. Inaddition this small light weight unit fits on a small 12"X18" table. With removable sink water and purewater container, you can place this almost anywhere.

Excellent product!

I am very happy with this machine.

This system does it all simply

It was very easy to put together and even easier to use. They seem to have thought of everything. I love the large reservoir that does not need to be filled up frequently and the lid that slides back making fills easy. The fact that it is able to make high ph water is a game changer for me and my health. Water is filtrated quickly and goes into a pitcher with an option to just fill up a glass. It’s performance is top notch and is a great value for your money, but most importantly it makes great tasting water.

Update at almost 90 days!

Update after nearly 3 months! Very happy. We live on a remote tropical island, with years of experience with RO systems on boats. We monitor our well water and Purewell RO water for TDS regularly now. Our well water before using the RO is at 140-175 TDS using our own calibrated meters. The Purewell Countertop RO system drinking water at 4-10 TDS, very clear and with great taste.

Reverse Osmosis

This counter water filter is FANTASTIC! We are so very pleased with the quality and the water!!

Water taste great

Good so far. I’ve had it for a few months and I’m getting a warning to change the SC filter now. So it’s lasted about the 90 days it claims.

Outstanding customer support

I’ve owned the unit for approximately eight months and recently encountered two problems with the unit. First, the pitcher’s fill mechanism froze up and wouldn’t allow refills. Second, a recently replaced alkaline filter failed at the seam causing a leak from within the filter housing. Customer support provided incredibly fast customer support and replacements.

Me encanta

Este filtro de agua fue el mejor gasto que eh echo es my lindo y muy útil me ahorré mucho dinero de estar comprando agua y solo abro la pila y le echo agua y el hace su trabajo, siento que el agua que filtra sabe mejor

Perfect

Really great tasting water! Does the job

No installation required

Súper easy to install !

Super affordable and easy to use

LOVE this filter! We've been using ours for about 4 months now. Changing out the filters is a breeze. The only downside is that you have to refill the tank, but if you want something that requires minimal installation this is it. The tank fills the pitcher about 2.5 - 3.5 times I think before you need to change the water. I thought the pitcher would just be handy to have, but I actually use it way more than the constant pouring spout. The pitcher stays absolutely spotless because it only is ever filled with the clean water. The tank can gather some hard water lines if you let the water sit too long, but you can always wash that out easy and not worry about it affecting the water you actually drink since it gets filtered. Bottom line, love this filter system! Renter friendly option, but also love having it even in our home that we own (and we have major hard water issues). The convenient clean water is worth every penny.

Great taste

The quality and taste of the water is great. I appreciate thoughtfulness of the tank cover to prevent the growth of algae.

Nice machine

Set up was easy. Water tastes good. Looking forward to enjoying filtered water.

Update, Issue Fixed. Alkalized My Water

Update****I was having an issue with the first machine. I returned it and the seller sent out a replacement. This one seems to be working fine. Nice product and great customer service.

Easy setup and absolutely delicious!

This machine makes the water taste so delicious. I compared it to many other filters, sink water or bottled water and this is by far the best I have tasted, other then some well water I had in the past. I use the water for drinking, cooking and also give to my animals. No more hevy metals for me and my family. I can feel the difference in my body and can see the difference in my face from using this filtering mechanism. Very easy to use. You just put the filter in the machine, add water from the tap into the jug provided and let it dispense a few times before drinking. After wards you have healthy tasty water. When the jug is almost empty, you dump the remaining water from the jug out and just refill the put it back onto the dispenser. That easy, plus it’s fast. I’ve had reverse osmosis machines that took forever to give me water. You have the option to get alkaline filters as well or a regular filter with out any added benefits. I switch out with both. Delicious!!!

Updated review. Don’t hesitate ORDER IT NOW!

Update: We have used this RO filter system for almost three months for a family of 7, we fill it with water approximately 2 and 3 times a day. The (water waste) is minimal compared to the other RO water filter systems and in fact it is water that we do not throw away because we reuse it for other household chores, even to water the plants and even on my water heater pad. We clean it weekly with mild soap and vinegar. It works great! I highly recommend it, it's a big difference even compared to the bottled water from spring! It was the best decision to make our investment in this system, I would give it 10 shinny stars if I could because it deserves them!

Easy to set up

Easy to set up. Easy to understand. Fits in the counter. I like having a pitcher and having a dispenser for individual glasses.

Easy and convenient

It's easy to use and very convenient. I have been looking for an alkaline water because of its health benefits. The size of the countertop water filtration is just perfect and I got it at a reasonable price.

Apartment Friendly!

I moved into an apartment and didn’t have space for a clunky water dispenser and tanks. But the water here is horrible. This fits perfectly on my counter and makes the water taste great! I didn’t think it was possible but it is amazing.

Very quiet

Very quiet and efficient. So far it’s working very well!

So far it's good.

We have been using the Frizzlife RO system for a couple of weeks now. It works well so far.

Good product

It's good nd easy to filter, past 2 months i didn't get any problem as of now.

Well designed.

Design and function is great. I have one request: make the lid on the pitcher stay more secure if possible. It sits very loosely and falls off to easily. Thank you.

Great Machine!

Makes great tasting water. We got the extra car at and keep it in the fridge. No more buying bottle water!

Tastes great!

Great product. Would recommend

Outstanding

Water is amazing!!!! It tastes great and feels cleaner in your mouth compared to store bought water or even bottled water. Even my pur filter can't compare. 110% satisfied. I still run my water through a pur filter and then a brita just to save the life of my frizzlife filter but it really isn't necessary. It does a great job even without pre filtered water

lo necesitaba

Me encanta el sabor , la velocidad en que filtra el agua ya estaba aburrido de cargar bidones de agua.
