One fountain, the filters and the pump that go with it
ATMZIQXR sells one water fountain for cats and small pets: the S18, a round 2.6-litre bowl made of 304 stainless steel with a spout on top and a small window that shows the water level. A low-power pump circulates the water through a carbon filter and a sponge, so it keeps moving and stays cleaner than in a still bowl.
Around it the brand offers the fountain alone or with spare filters, replacement filter packs for three to ten months and a spare pump. Below is every option we found in stock from the brand’s own seller on this marketplace, each with its own card.

The fountain
S18 Stainless Steel Cat Water Fountain 2.6 L
An 88 oz fountain with a bowl and lid of 304 stainless steel in a matte finish. A 0.8 W pump lifts the water through a curved spout and lets it run back into the bowl; on the way it passes a pre-filter sponge on the pump and a carbon filter box with fabric, activated carbon and ion-exchange resin. The listing rates the pump at 25 dB or less, and a round window on the side shows the water level (it glows softly at night). According to the brand one fill lasts a single cat 7–9 days. Power comes from a cable; it is not battery-powered.

Refills
S18 Replacement Filters (Carbon + Sponge)
Each set is a white carbon filter box and a black high-density sponge. The filter box holds layered fabric that catches hair and debris, activated carbon from coconut shell against odours and chlorine, and ion-exchange resin that softens the water; the sponge sits on the pump intake and keeps fine particles and fur out of the motor. The brand recommends a new set every two weeks, sooner with several pets. Soak a new filter for five minutes before fitting it. Made for the ATMZIQXR S18; the listing also names several same-style steel fountains, so compare the shape if you own another brand.

Option 1
Why cats take to it
What the S18 is designed to do, in four pictures.
01
Moving water tempts cats to drink
Many cats ignore a still bowl but drink from a running tap. The spout gives them a thin stream and a gently moving surface, which buyers say gets their cats drinking more.
02
See the level at a glance
The round window on the side shows how much water is left without lifting the lid, and a soft light behind it makes it visible at night too.
03
Stainless steel instead of plastic
Bowl and lid are 304 stainless steel. Smooth steel is easy to scrub and does not hold on to smells the way scratched plastic can.
04
Filters that are quick to swap
The carbon filter box clips over the pump and the sponge slides onto its intake, so a fresh set goes in within a minute every two weeks.
What the S18 gets right
Quiet pump
A 0.8 W pump rated at 25 dB or less, quiet enough for a bedroom as long as the water level is kept up.
Four filter stages
Sponge, fabric, activated carbon and ion-exchange resin catch hair, debris and odours.
Water-level window
Check the level from across the room and refill before the pump runs low.
Easy to take apart
Lid, spout, filter and pump come apart by hand for cleaning; the pump impeller pops out too.
Setup and cleaning
The steps from the brand’s installation and pump-care instructions, in short form. Always follow the manual that comes with the fountain.
Prepare the filter
Rinse the new carbon filter under the tap to wash off loose carbon dust, then let it soak in water for about five minutes.
Fit the sponge to the pump
Slide the black sponge into the intake cover of the pump and close the cover, so everything the pump sucks in passes the sponge first.
Place pump and filter
Set the pump into its seat in the middle of the bowl and put the carbon filter box over it.
Close the lid and fit the spout
Put the steel lid back on and push the spout onto the outlet.
Fill and plug in
Fill the bowl with fresh water, connect the cable and the water starts to flow. Keep the level above the minimum so the pump stays quiet.
Clean the pump every 1–2 weeks
Take out the pump, open it, remove the impeller and brush away hair and slime; rinse the bowl and lid at the same time.
Filters and cleaning schedule
Change the carbon filter and sponge every two weeks, more often with several pets. Empty, rinse and refill the bowl every few days, and clean the pump and impeller every one to two weeks; the brand links a clean pump to a longer pump life. Use fresh drinking water and never run the pump dry.
If something seems off
- The fountain got louderUsually the water level is low or hair is stuck in the impeller. Top up the water and clean the pump.
- The water flow is weakClean the impeller and the sponge, and check that the spout is pushed firmly onto the outlet.
- Black specks in the waterThat is carbon dust from a new filter. Rinse and soak new filters before fitting them.
- My cat ignores itMany buyers report that cats need a few days to a week to get used to a fountain. Place it away from the food bowl and litter box.
This guide describes product features as stated in the listings and the brand’s instructions. If your pet suddenly drinks much more or much less than usual, ask your vet.
What buyers say

“We wanted to switch to stainless steel for a more hygienic option and we absolutely love this! It’s so easy to clean and unlike plastic fountains, this one actually feels clean after you wash it.”
★★★★★
“Very easy to assemble, clean and quiet. The pump provides a continuous stream of water. The fountain is a nice size and holds plenty of water. It is durable and stays in place. It took my cats a week to get used to it. They stared it down for a week lol.”
★★★★☆
“I replaced my plastic cat water fountain with a stainless steel one to avoid microplastics. I was also looking for a design that is easy to clean. Fountain was easy to set up and is very quiet. I like the round design and small footprint on my kitchen floor.”

★★★★★
“Filters work great and they fit perfectly in the water fountain. Easy to clean and inexpensive enough to replace when needed.”

Frequently asked questions
What is the difference between the fountain bundles?
It is the same S18 fountain in each. “Fountain only” comes with one carbon filter and one sponge already fitted; the other bundles add spare filters and sponges, enough for about three or four months of changes.
How often should I change the filter?
The brand recommends a new carbon filter and sponge every two weeks, and sooner in homes with several pets. Rinse and soak each new filter for about five minutes before putting it in.
Which filters fit the fountain?
The ATMZIQXR S18 filter packs (12, 16, 24 or 40 pieces, always half carbon filters and half sponges). They are made for the 2.6-litre S18; the listing also names several same-style stainless fountains of other brands, so compare the shape before buying them for another fountain.
How quiet is it?
The listing rates the 0.8 W pump at 25 dB or less, and most buyers describe it as almost silent. It becomes louder when the water level drops or hair collects in the pump, which is a useful reminder to refill or clean it.
How long does one fill last?
The bowl holds 2.6 litres (88 oz). The brand says that is 7–9 days for one cat; with several pets, dogs or warm weather you will refill more often. Keep the water above the minimum level.
Is the fountain cordless or battery-powered?
No. It runs on a power cable and has to stay plugged in. There is no battery inside.
How do I clean it?
Lid, spout, filter and pump come apart by hand. Rinse the steel bowl and lid every few days, and every one to two weeks open the pump, take out the impeller and brush it clean.
Can dogs or other pets use it?
Yes. It is designed for cats, and the listing and buyers also mention small dogs. The open bowl suits small animals; large dogs will empty it quickly.
Can I buy a spare pump?
Yes. The S18-PUMP is the original replacement pump for the 2.6-litre S18 fountain. It is waterproof to IPX8, has a 1.5 m cable and only fits this fountain.
What do buyers say about it?
Buyers mostly mention how quiet it is, how easy the steel bowl is to clean and that their cats drink more. On the other side, Amazon’s summary notes some reports of pumps failing after several months, so cleaning the pump regularly and keeping a spare is worth considering.
