At Purewell, we want you to feel confident when shopping for home and outdoor water filtration products. This Return & Refund Policy explains how returns, refunds, exchanges, damaged items, missing items, replacement filters, and product-specific return conditions are handled.

This Policy applies to purchases made directly through www.purewell.com. If you purchased a Purewell product through another retailer, marketplace, reseller, or distributor, please contact that seller directly for their return and refund policy.

1. 30-Day Return Window

We offer a 30-day return window. This means you may request a return within 30 days after receiving your item, provided that the item meets the eligibility requirements in this Policy.

To start a return, you must contact us before sending any item back. Items returned without prior authorization may not be accepted.

2. Return Eligibility

To be eligible for a return, the product must generally be:

Returned within the applicable return window.
Unused, uninstalled, unfilled with water, and in the same condition as received.
Returned with original packaging, manuals, accessories, components, and proof of purchase.

Purewell reserves the right to refuse a return or reduce the refund if the returned product does not meet these conditions, subject to applicable law.

3. Drinking Water Hygiene Policy

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.

4. Non-Returnable Items

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.
Opened, used, activated, primed, expired, or contaminated replacement filters.
RO membranes, filter cartridges, carbon filters, gravity filter elements, outdoor filter elements, and other consumable filtration components once opened or used.
Products missing original packaging, manuals, accessories, or required components.
Products damaged by misuse, neglect, improper installation, unauthorized modification, or incompatible accessories.
Gift cards, digital products, final sale items, clearance items, or customized products where applicable.

5. Replacement Filters and Consumable 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.

Outdoor water purifiers, filter pumps, water filter bottles, water filter straws, soft flasks with filters, and similar products must be returned unused, clean, dry, and complete with all original components.

We will review the issue and may send the missing item, provide a replacement, or offer another appropriate solution.

If the return is caused by customer preference, ordering error, change of mind, incorrect product selection, or other customer-related reasons, the customer is generally responsible for return shipping costs. The exact cost depends on the carrier or shipping service selected.

If the return is caused by Purewell, such as an incorrect item, damaged item, verified defect, or fulfillment error, Purewell will cover the return shipping cost or provide another suitable solution in accordance with this Policy and applicable law.

Once you ship a return, please provide the tracking number to Purewell promptly. We recommend using a trackable shipping service and keeping proof of shipment. Purewell is not responsible for returns lost in transit when the customer arranges return shipping.

15. Inspection and Refund Approval

After we receive your return, we will inspect the product to confirm condition, completeness, eligibility, and compliance with this Policy. We will notify you whether the refund is approved, partially approved, denied, or requires further review.

If the returned product is used, damaged, missing parts, missing packaging, contaminated, or not in eligible condition, we may reduce the refund, refuse the return, or return the item to you, subject to applicable law.

16. Refund Processing

If your refund is approved, the refund will generally be issued to the original payment method within 3–7 business days after approval. Your bank, credit card issuer, payment provider, or payment network may take additional time to process and post the refund.

17. Exchanges

Where available, we may offer exchanges for eligible items. The fastest way to receive a different product may be to return the eligible item and place a new order after the return is approved.

Exchanges are subject to product availability, condition requirements, shipping limitations, and applicable law.

18. Promotions, Bundles and Gifts

Orders purchased with discounts, coupon codes, bundles, gifts, free items, or promotional offers may be refunded based on the amount actually paid after discounts. If a bundle or promotional set is returned partially, the value of any retained items, gifts, or discounts may be deducted from the refund.

Promotional items, free gifts, or bonus products may need to be returned with the original order to receive a full refund.

For eligible online purchases in the European Union, consumers generally have the right to withdraw from the contract within 14 days after receiving the goods, subject to legal exceptions. UK online consumers generally have similar cancellation rights. Certain items, including goods that are not suitable for return for health protection or hygiene reasons once unsealed after delivery, may be excluded where permitted by law.

Nothing in this Policy limits your mandatory statutory rights.

21. Warranty Claims vs Returns

A return request is different from a warranty claim. Returns are generally handled within the return window and based on product condition. Warranty claims are handled under the applicable product warranty and may relate to defects in materials or workmanship during the warranty period.

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.

24. Contact Us

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.

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.

Best purchase I've made

Best investment I've ever made , water fast clean refreshing you can tell the difference between bottled water and clean water. Instalation was easy and fast durable material , safe and the material is very very good! 10/10

Great filter at a very good price.

This arrived packed very well, and I'm now using my new filter. Thanks a lot!

Excellent purifier

Great system. Had a Berkey for four years and this is better quality and filtration.

Taste fresh

I can taste the difference from other filtered water. Purewell did a good job!

Filtered water

Excellent product! I couldn’t be happier with this purchase. No more residual hard water stains in my electric kettle, not to mention not consuming unfiltered water. It’s easy and efficient.

Great water filter!

My water tastes better than it has in a long time. It doesn't take long for it to work. Just be sure not to fill it up until it is almost empty.

Great quality. I like the unit itself better than the Big Berkey I used to own.

I really like this water filter. For the price, it is very comparable to my old Berkey system, and at some point, if I want to use Berkey filters, I can do so. This unit is of a higher quality than the Big Berkey system I used to have of the same size. The spigot is higher quality but fills bottles more slowly. The sight glass spigot features a floating ball that helps you see the water level, and the unit comes with a stand that has been particularly helpful in keeping it elevated at a convenient height on the countertops I have used it on. The water tastes great, and this has been very helpful for me over the last 6 months of use. It can only accept two filters, whereas a Big Berkey can accept four, but I don’t mind.

Kitchen must have Appliance!

I really never knew how much I would appreciate this item to my started to use it. Very effective for final cleansing of any drinking water or in food preparation. If you have a portable ice maker, I highly recommend using the filtered water from this device to prevent unnecessary cleaning. Finally this is a must-have device if you know you are going to be without water due to Plumbing issues in the neighborhood or a natural disaster such as a hurricane!

Great quality

This water filter has been great for the price. It fits perfectly on my counter without taking up too much room. It was so easy to install and clean. The water tasts great coming out of it. Overall it is a great alternative to the really fancy expensive ones.

Superb water filter

It is the best purchase I’ve made in a while. Water is filtered so well, no odor, tastes great.

It works

Great product so far

Works very well.

I did test the PH levels after setting this up. Seems to work great for filtering my acidic well water. Can actually tastes the difference.

Couldn't be happier

I'm very happy with this purchase. Easy to set up, easy to use, and great quality water.

It dies everything it claims.

It does EVERYTHING it says it will do.

Water

So far so good

Great Product & Value

I wish I had ordered this water filtration system sooner. We love the clean, sweet taste of the water it produces. We are a family of 2 and this system produces a lot more water than we thought it would from the first day we set it up. I highly recommend this system. The city water where we live is full of some sort of white chalky stuff, tastes bad, smells bad and has way too many chemicals. This water system is the next best thing to distilled water. The Purewell system makes the water taste even better than store-bought water in plastic bottles. Give it a try. If your city or well water is as nasty as what we have here, you will be so happy you took the chance to try this Purewell Water Filtration System. We are happy we chose to buy it and are enjoying the clean, sweet water we now are able to drink. We are very happy customers of the Purewell Water Filtration System.

Replace that bottled water

One of the best purchases I've made in a long time!

Great taste

Easy to use and great tasting water.

Good water

We bought this several years ago. I had never used one before. We use this for filtering rain water and it works great. At times the filters don't function well but when that happens you can take the filter out, scrub with a plastic brush, and reinstall once you have allowed the filter to get resaturate. That seem to do the trick for us. The cleaner the water to begin with the longer use you can get out of each filter too. I know that sounds like common sense but just thought I'd mention it.

Excellent product, read the instructions!

This is a great product so far. The quality of the water is great, it just takes a bit of priming to get it going!

Buy it

Worth the money!

A good one.

Well made and the water tastes good.
