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.

NOT THE BARGAIN IT SEEMS

Not the bargain it looks like......100 gallons per filter sound great, got this to use with zero water 40 cup glass system.First filter got about 3.5 gallons before filter clogged, emailed Purewell they suggested it may just be one off, said try a second filter , it filtered maybe 10 gallons when it stopped, took all night to filter half gallon.The water I am filtering has TDS of 180-190 I have been using Zero water filters for years getting 50 to 60 gallons from one filter.CAN NOT RECOMMEND, NO SAVING TO BE HAD FOR ME.

Thanks for the note on filtration performance �� the specialty filters target fluoride, chlorine and PFAS specifically. Contact support@purewell.com and we will recommend the right combination for your water.

Tap water has the potential to leak past the filter

Doesn't make a tight seal. Sometimes the tap water keaks onto the pitcher.

Sorry about the leak �� in most cases it is a spigot or gasket that is not fully seated. Contact support@purewell.com and we will send a replacement right away.

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

Terrible - not worth the money!

Very slow filtering for first several days. Lasts only slightly longer than Zerowater filters. My tap water TDS is about 360.Zero water filters last about 10 days and cost $12.50 each in an 8 pack = $1.25/day.These filters last 13 days and cost $32.50 each in a 4 pack = $2.50/day.Total Ripoff.

Sorry the flow is slower than expected �� filters usually speed back up after a quick back-flush, and heavily silted water can clog them sooner. Contact support@purewell.com and we will help you get it running at full speed.

EXCELLENT FILTER REPLACEMENT FOR ZERO WATER

THIS PUREWELL O TDS 7-stage water filter, fits my 22 Cup Zero Water countertop system perfectly, and my initial TDS tester shows a O reading.I live in Indiana where the tap water is awful. Out of the faucet, it tests at about 359. The harder/worse your water tests, the shorter the life of any filter you choose. Prior to purchasing this filter, I was replacing with either actual Zero Water filters or off-brands. They all lasted 2-3 weeks for me (one person household.) I use filtered water for drinking, cooking and for my small 14lb dog��s water bowl. Obviously, the larger the household, the harder the water and the more water that is filtered, so the filter life is shortened accordingly.I wanted to try the PUREWELL 7 - stage replacement filter for two reasons:1. The original Zero water replacements, and substitute brands, although testing zero for TDS and are fine initially, have an extremely off-putting fishy smell and taste as soon as they reach about 4 on my TDS tester. Recommended replacement is at 6, but I can��t go that far. I was probably getting approx 11 gallons per filter at a cost of about $1.25/gallon.2. The PUREWELL 7-stage offers a better filtration system and although pricier upfront,So far, the water tastes fantastic- better than any bottled water. If the filter lasts as long as is noted in the very nice PUREWELL instruction booklet, I should get between 30 and 50 gallons of great tasting water, before replacement is needed. By my calculations (math is not my strong suit- haha,) this calculates out to between .75�� -1.25 a gallon. If I fill my own jugs at a local store, it costs approximately .69��/gal. It��s a pain to do and haul in and store If I purchase ready-to-go gallons, my cost is anywhere from $1.29 to $1.59. I��d rather purchase these and filter at home without the hassle! I think this should end up costing about the same as the Zero water filters with the benefit of better filtration system.I will point out that the PUREWELL filter is a bit longer and the diameter of the actual filter portion is wider, so it displaces a little more water in the tank. It seems to filter at the same pace as the original Zero Water filters.I will update after I need to replace my first PUREWELL 7-Stage.

We love hearing this �� thank you for trusting Purewell with your daily water. Here is to many more clean, fresh glasses!

Filters 2000 gallons? Not even close.

Tried this as a longer lasting filter my Zero Water 32 cup dispenser. The description says it will filter 2000 gallons of water. I bet I didn't even get 100 before water stopped passing through the filter. It says it's a Zero Water replacement and that's what you'll get-zero water.

Filter life depends on your water source and how often you use it. Contact support@purewell.com with your setup and we will recommend the right replacement schedule.

Didn't work for me.

This did not filter the water. I put water in, checked in the morning and the water was still in the hopper waiting to percolate. This was used in a Zero Water brand.

Better choice

So far this is an excellent replacement for the zero water filters. Zero Water has changed their filters in my opinion and they go bad way to often with a very ��off�� taste. This one has been great!

Not worth the price

The filter didn��t even last a week. And it��s not like I��m drinking a ton of water every day. Not worth the money.

Clogged up on well water.

The filters did not work for me. I am on well water and have a whole house water filter for sediment. I was hoping these pitcher filters would be an additional option to remove TDS after already having gone through the sediment filter. I purchased the two pack sets and water would not pass through either of the two.

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.
