How the filters work?

PurrWell uses an Advanced Multi-Stage Water Purification System,
not just a basic carbon disc like most cheap fountains.

Each filter contains 5 layers working together:

-Fine Mesh Filter Layer
The first line of defense. Catches loose fur, hair and debris before
it ever reaches the water.

-Mineral Enrichment Beads
Remove food residue and impurities that make water taste stale and
discourage cats from drinking.

-Activated Carbon Core
Absorbs odours and neutralises contaminants keeping every sip
tasting clean and fresh.

-Natural Mineral Stones
Filter out unwanted particles that pass through the earlier layers,
adding an extra level of purity.

- Coconut Carbon Sponge
The final stage. Supports clean water flow and removes any remaining
trace impurities before the water reaches your cat.



-How often should I change the filter?

Change your filter at minimum every 4 weeks for best results and to make sure your cat always has the cleanest water possible, we recommend changing it every 1-2 weeks.

A clogged or worn filter is one of the main reasons cats stop
using fountains
. Staying consistent with filter changes keeps your
cat drinking regularly and the fountain running at full performance.

Your bundle includes 4 filters, covering your first month of
weekly changes, or up to 4 months at the minimum schedule.

Hear It From Cat Moms Like You

Check out some reviews and hear what cat parents are saying about PurrWell.

I was sure she'd ignore it like the others

Honestly I almost didn't order it. My cat had snubbed two other fountains and I figured I'd just wasted money again. She sniffed it the first evening and walked off, classic her. By the third day she was drinking from it on her own without me doing anything. I genuinely didn't expect that after the last two.

No more slimy film every two weeks

My old plastic fountain got that horrible slippery coating inside within days, no matter how often I scrubbed it. This one is the first thing that's actually stayed clean between washes. I wipe it down once a week and it still looks new. That alone was worth it for me.

Talked myself out of it for weeks over the price

I'll be honest, I went back and forth on this for a while because it costs more than the cheap ones. What changed my mind was realising I'd already bought three cheap ones that all ended up in the bin. I'd rather have spent it once. Two months in and I'm not looking at fountains anymore, which is a relief.

Quiet enough that I forget it's on

My biggest worry was noise because my last one hummed all night and my cat hated it. This one I genuinely have to look at to check it's running. It's in the same room as where she sleeps and it hasn't bothered her once. She's nervous about everything, so that says a lot.

I thought my wife was overthinking it. I was wrong.

My wife had been quietly worried about our cat barely touching her water and wanted to try this. I thought it was a lot for a water bowl, I'll admit. Our cat took to it within a couple of days and drinks from it constantly now. I'm the one who reminds my wife when the filter's due now, so I've clearly come around.

Frequently Asked Questions

How often do I really need to change the filter?

We recommend changing it weekly for the cleanest, best-tasting water, which is what most cats respond to best. At minimum, try to change it every four weeks atleast. A clogged or worn filter is one of the most common reasons cats start ignoring a fountain that used to work for them, so staying on a regular schedule matters more than people think. An 8-pack covers about two months at the weekly schedule, or up to four months at the every-two-week schedule.

How is this different from generic carbon filters I can buy elsewhere?

PurrWell filters run water through five purification stages: fine mesh, mineral enrichment beads, activated carbon, natural mineral stones, and a coconut carbon sponge. Most cheap replacement filters are a single carbon disc, which catches large debris and not much else. The five stages are why the water still tastes clean a week in instead of going stale by day three. They're also shaped specifically to seat correctly inside the PurrWell fountain, which generic filters do not.

How does the subscription work?

We send a fresh pack every 30 days automatically. The subscription price stays the same 25% off every time, not just on your first order. There is no contract, no minimum number of shipments, and no hidden renewal fees. The first pack ships within 1-2 business days like any other order, and every pack after that ships 30 days later.

Can I cancel anytime?

Yes, cancel anytime, no minimum and no questions asked. You can cancel from your account dashboard in a couple of clicks. If you would rather we just handle it for you, email support@trypurrwell.com and we'll take care of it the same day.

When will my next shipment arrive?

Your first order ships within 1-2 business days, with delivery typically 2-7 business days after that. After your first pack, the next one ships automatically (every 30 days). You'll get an email with tracking the moment each shipment goes out, so there are no surprise charges and no guessing.

What if I just want to buy a one-time pack?

Totally fine. The one-time option is right at the top of the page and there's no obligation, no follow-up subscription, no funny business. A lot of cat moms start with one pack to see how long it lasts in their household before deciding whether the subscription makes sense for them. You can always switch to the subscription later if you decide it's easier.
