Because Purewell products are used for drinking water filtration, hygiene and product safety are important. Products that have been filled with water, installed, activated, primed, connected, used, or otherwise exposed to drinking water may not be eligible for resale or standard return processing.

For hygiene reasons, used water-contact components, opened consumable filters, and products that show signs of use may be non-returnable unless the return is related to a verified defect, damage, or incorrect item caused by Purewell.

The following items may not be eligible for return or refund unless required by law or unless the issue is caused by Purewell:

Used, installed, filled, activated, or water-exposed products.

Replacement filters are consumable products. This includes gravity filters, RO filters, RO membranes, carbon filters, outdoor filter elements, bottle filters, straw filters, pump filters, and similar filtration components.

For safety and hygiene reasons, replacement filters may only be returned if they are unopened, unused, unprimed, uninstalled, and in original packaging, unless the item is defective, damaged, incorrect, or otherwise required by applicable law.

6. Gravity Water Filter Systems

For countertop gravity water filter systems, all chambers, lids, spigots, stands, water level windows, filters, washers, seals, and accessories must be returned complete and in original condition.

Gravity systems that have been assembled, filled with water, used for filtration, contaminated, dented, scratched beyond normal inspection, or returned with missing parts may not qualify for a full refund.

7. Countertop Reverse Osmosis Systems

Countertop RO systems must be returned with all tanks, pitchers, filters, membranes, power adapters, accessories, tubing, manuals, and packaging included, where applicable.

RO systems that have been installed, flushed, filled, activated, connected to power, connected to water, or used may be subject to inspection and may not qualify for a standard return due to hygiene, performance, and resale limitations.

If your issue occurs after the return window, please contact us so we can determine whether warranty support may apply.

22. Water Quality and Performance Expectations

Water filtration performance, water taste, water clarity, flow rate, TDS readings, and filter lifespan may vary depending on local water quality, source water conditions, contaminant levels, water temperature, usage frequency, maintenance, and filter age.

Dissatisfaction based solely on taste preference, flow rate expectations, local water conditions, or misunderstanding of filtration technology may not qualify as a defect unless verified through product evaluation or required by applicable law.

23. Policy Updates

We may update this Return & Refund Policy from time to time to reflect changes in our products, operations, logistics, legal requirements, or customer service procedures. The latest version will be posted on this page with an updated date.

Step 01Prepare Parts Step 02Assemble Lid Step 03Install Spigot Step 04Install Filters Step 05Stack System Step 06Flush Before Use

Prepare and Clean the Parts

Before assembly, check the main parts and clean the system components.

1
Wash Your Hands Handle the system with clean hands before setup.
2
Check Included Parts Make sure the chambers, lid, spigot, stand, and core filters are ready.
3
Clean Before Assembly Rinse the chambers and accessories before first use.

Note: Use cold or room-temperature water only. Do not use hot water.

2
Add Washer and Gasket Place the washer and gasket in the correct position.
3
Tighten the Screw Fasten the knob until it feels stable.

1
Insert the Spigot Place the spigot through the lower chamber hole with the gasket and washer.
2
Add the Inside Parts Place the remaining washer and gasket from the inside of the chamber.
3
Tighten the Hex Nut Use the wrench to secure the spigot vertically.

Before filling: Make sure the spigot is closed to help prevent leaking.

Install the Core Filters

Use the required number of core filters for your system model.

1
Insert the Core Filters Place the core filters through the holes in the upper chamber.
2
Secure the Filters Use the filter washer and wing nut to hold each core filter in place.
3
Check Stability Make sure each core filter is firmly installed before adding water.

Note: This guide uses “core filters” only. Filter type and quantity may vary by system option.

2
Place the Lower Chamber on the Stand Set the lower chamber securely on the stand.

System Type Countertop Gravity System

Filter Reference Core Filters

First Use Flush 2–3 Times

Water Temperature 40°F–100°F / 4–37°C

How It Works

How the Filter System Works

Water is added to the upper chamber and moves through the center filter by gravity. After filtration, water collects in the lower chamber and is ready to dispense from the spigot.

1. Fill the Upper Chamber

Add water to the top chamber. The system works without electricity, plumbing, or pressure.

2. Gravity Moves Water Through the Filter

Water naturally flows downward through the center filter element, where the filtration process takes place.

3. Filtered Water Collects Below

After passing through the filter, water collects in the lower chamber for storage and daily use.

4. Dispense When Needed

Open the spigot to pour filtered water for drinking, cooking, or everyday hydration.

Filter Replacement

Filter Replacement Guide

Replacing filters on time helps your filtration system keep working properly. It also helps maintain water flow, drinking water taste, and everyday use confidence.

Track Usage Time & Filter Life

Filter life may vary by water quality, usage frequency, and total water volume filtered.

Rated Filter Life Reached

Replace the filters when they reach the rated lifespan listed for your filter model.

Water Flow Becomes Slower

If filtering takes much longer than usual, clean or replace the filters as needed.

Taste or Odor Returns

If unwanted taste or smell becomes noticeable again, it may be time to replace the filters.

Source Water Matters

Rain, river, stream, or well water may shorten filter life compared with regular tap water.

What to Check Before Replacing Filters

Confirm Compatibility

Choose filters that match your filtration system, filter series, and setup.

Prepare New Filters

Prime, rinse, or flush new filters according to the product instructions.

Check Seals & Washers

Make sure washers, seals, and threaded parts are installed correctly.

Clean the System

Empty and clean the upper and lower chambers before installing new filters.

Replace Sets Together

If your system uses paired filters, replace matching filters together when needed.

Record the Date

Write down the replacement date and set a reminder based on your usage.

Purewell water 2.25 gallon

I am enjoying using this, had a few times where it ran out and i forgot to turn the nozzle to off, so it made a big mess once refilled. I wish instructions or a video of putting this thing together was available. I have two extra filters I don't know how to use. Any help with this? I am not gong to be bringing water home from the store anymore. Woohoo! Would definitely buy this again. Thanks

Great product!

We have county water, and the report was eye opening! Such a difference since the Purewell, clear, no chlorine or bad taste and happy to get rid of the fluoride,
Thanks for a great product!

Fits perfectly

These fit my Purewell system perfectly. So far, work very well. I do recommend these if you are looking for replacement filters with thread.

Works great, simple operation.

High quality water filters. Easy to assemble.

The product worked well for my needs

Good value for the money, second time purchasing this product, works well, good quality

Great replacement filters

I really am happy to have these replacement filters for my Purewell water filter. These are just like the originals and install the same way.

I followed the included instructions so replacement was very easy and they included the steps for priming the new filter. It is working great and the water tastes wonderful.

Superior Filters

Fit was perfect... it only had to match the diameter & thread of the holes after all.

Nice filter

No noticeable difference in quality or functionality with other brands. I would buy more of this brand. Nothing bad to report.

Good replacement option

It is obvious that these filters are basically identical to the Berkey brand we are currently using. We have no way to prove they are internally identical or have the same filtering capacity or efficacy, but they do offer a cost-effective alternative for replacement filters. Time will tell if they last as long, but for the savings offered we will give them a go! If nothing else, great to have on-hand for emergency prep.

This is an excellent product.

Very simple to do if you follow the instructions. These filters can last years if you keep them clean.

Decent Filter, Good Price

I would be happy to buy two sets of these instead of one set of name brand filters, as the two sets will last longer. If your looking for a good deal on water filters that work, these are worth looking at.

Works like factory

The filters fit nicely in my Berkey. The fit is very similar to the factor filters. They work in the same manner. They come with everything needed to prep the filters and install them. The water tastes the same, and the readings that I get from my gauge are very similar. The filtering process is virtually the same.

Buy

This works amazing.

Greay for daily use

I got three of these and I love the simple design. They're easy to use. The water tastes great out of this. I'm happy with it.

Works with Berkey

These replacement filters work great in our Berkey and are more cost effective. They appear to be doing their jobs just as effectively as the originals and we've had no issues with them. We're very happy with them and will buy again. Great value for price.

Great!

Works even better and faster than original filter.

Great value

I have a Berkey and these fit great. re they exactly as the original black filters? I dont know but I do know that they work pretty much the same way. I do have a main whole-house filter to do most of the work but this is great for the final drinking water step. I chose this style of filter because I want the impurities to be filtered out but the minerals to remain.
It sets up easy and I always try to have spares in case of an emergency. This is also a very good price. Its not super cheap (which is questionable) but its reasonable compared to the original filter. I think its good.

stocked up.

just what I ordered as extras, all good.

Compatible with out Travel Berkey

Water taste good

Good replacements for my new system.

I recommend this Purewell replacement filter set. Remind: you need to confirm if this filter with thread fits your system or not.

Love Purewell

They work great. I'm afraid to try cheaper ones. Love my Purewell.

work great

These work great at filtering out pretty much everything. They are a little pricey, but in the bigger picture worth it for your health and for your waters taste.

Purewell water filters

We needed new filters after over 6 months of use and these are the perfect fit for our Purewell water filtration system.

Good Quality

My water is very bad. Lots of iron so I’m happy to get a month out of these filters but the water that is filtered is very good. I’m sure the filter would last longer if the water wasn’t so mineralized

Heck of a deal on these.

These filters are nearly indistinguishable from the OEM versions and as near as I can tell, they work every bit as good as the real thing.
These will fit into many different brands of gravity type filters. I have 3 different brands and these fit in all of them.
I have been filtering my own water for decades and these are used every day. Even When I travel, I bring my own water.Lots of it - even into restaurants. I hate the smell and taste of tap water and the stuff that's in tap water worries me.

Anyway, great deal on these and a good value.

These are great.

These filters are exactly described and pictured by the vendor.

Fits in almost all gravity type filters except the very small ones.
The difference between water from the tap and water that has been filtered by these filters is like night and day. Virtually no comparison.
These filters remove almost everything nasty and smelly. They don't just improve the taste, they remove over 200+ contaminants like chlorine, heavy metals - and more.
I have been using filters very similar to these for decades and wouldn't be without them. Tap water is a no go for me. The filtered water from these is great for cooking too.
It's hard to explain how good there really are. You need to experience it for yourself.

I 100% recommend getting and using these. Great deal and a good value.

Works great! Better price.

The well water from my tap is wonderful & has no odd taste or smell now. I'm saving $$$ by not buying bottles & it's convenient to use right on my countertop. The unit looks nice as well. Would recommend.

Gives great water!

Ours only last 5 months but the water quality is awesome. I wish it was easier to prime them, don’t forget to do this step.

Great filter

Great filters work as well as the much more expensive name brand ones.

Good filtters

They do the trick well.

These filter water

These are easy to install, they seem to work similarly to the Berkey although I don’t have a way to test the water to see if it filters the same as the Berkey filters. They look so very similar to the original Berkey filters, the water once flushed sufficiently tastes clean. These are not a solid core filter there is space on the inside of the filter which cheapens the filter in my opinion. The original Berkey filters were a solid carbon filter there wasn’t space for the water to sit.
