Catit Flower Fountain Filter Comparison

The Catit Triple Action Fountain Filters are sold in packs of 2 or 5. If you buy them in packs of 5, which are a much better value, the filters are approximately $3.00 each.

PetStandard is a trusted company that has been making affordably priced replica pet fountain filters for several years. The PetStandard Water Filters for Catit Flower Fountains is also compatible with the Catit Design Senses and the Catit Fresh & Clear Fountains.

PetStandard’s filters are virtually identical to the original Catit Triple Action Fountain Filters. They have a slotted plastic base, 2 activated carbon compartments, 2 water-softening compartments, and a polyester mesh top. The only visual difference between these two filters is that the PetStandard Filter has a slightly thinner and denser foam topping than the Catit Triple Action Fountain Filter. In the picture below, the PetStandard Filter is on the left and the Catit Triple Action Filter is on the right. The differences are barely noticeable. 

The PetStandard Water Filters are sold in packs of 6 and cost approximately $2.50 each.

Fatkitt is another off-brand filter company that has recently popped up in response to the high demand for affordable fountain filters. The Fatkitt Carbon Filters are nearly identical to the PetStandard Water Filters. They have the heavy-duty plastic casing and compartments for water softening media and activated carbon. The mesh foam is similar to that of the PetStandard Filters in that it is relatively thin and dense.

The Fatkitt Carbon Filters are sold in packs of 8 and cost approximately $2.11 each. This is the best value filter currently on the market that has water-softening functionality.

The Catit Fresh & Clear Foam / Carbon Filters were designed for the Fresh & Clear Fountain, but they also work in the Catit Flower Fountain. We have found that these filters don’t last quite as long as the Catit Triple Action Filters, the PetStandard Filters, or the Fatkitt Filters. Replacement is recommended every 3 weeks for the Catit Fresh & Clear Foam / Carbon Filters.

The Catit Fresh & Clear Filters aren’t nearly as robust as the Triple Action Filters that came with the Catit Flower Fountain. The Catit Fresh & Clear Filters are dual-function filters. They consist of a carbon layer to improve taste and a foam layer for filtering out solids and impurities. The two pliable layers are sewn together. The entire filter is about half the thickness of the Triple Action Filter.

When placed in the Catit Flower Fountain, the white foam side should face up and the black carbon side should face down. Since these filters aren’t as thick as the filters specifically designed for the Catit Flower Fountain, you may notice some floatation. But as long as the fountain is filled to the appropriate level, the filter should work just fine. These filters have a slightly larger diameter which makes them not fit all the way in the recessed compartment. But again, they do fit inside the fountain and provide adequate filtration.

You should always thoroughly rinse carbon filters prior to use, but with these Catit Fresh & Clear Filters in particular, they might need 2 or 3 times the amount of rinsing to get all the loose carbon off. If you skip the rinsing, you’ll notice black debris starts to circulate in your fountain almost immediately. While activated carbon doesn’t pose any health problems if ingested, it is definitely a nuisance if you’re trying to keep the fountain clean.
