ROJECO Cat Fountain Replacement Filters
£9.25
This ROJECO replacement set contains 6 carbon fountain filters and 2 sponge filters for ROJECO cat water fountains. The manufacturer states that it is designed for the ROJECO fan-shaped wireless water dispenser. The sponge filter catches hair and food debris before they reach the pump, and the carbon filter helps with chlorine taste and odours, so your cat's water stays fresh.


Key features
- Carbon and sponge filtration: traps hair, dirt and debris, and helps improve taste and odour.
- Activated carbon: helps with chlorine taste and unpleasant odours.
- Sponge filter: catches larger particles before they reach the pump, which helps protect it.
- Change every 2 to 4 weeks: six filters give you several months of spares.
- Easy to fit: a drop-in swap with no tools needed.
Carbon filter and sponge filter
The set filters in two stages. The sponge filter catches hair, debris and large particles first. The curved carbon filter then works on finer impurities, and the manufacturer states that it removes residual heavy metals.

Filter materials
The manufacturer lists three materials in each carbon filter:
- Pure coconut shell activated carbon
- Ion exchange resin
- Non-woven fabric as the outer layers

Replace every 2 to 4 weeks
Change the filters every 2 to 4 weeks, or sooner if the water looks cloudy or the flow slows. Soak and wash every new filter before use.

Rinse the filter before use
Soak the new carbon filter in clean water for 2 to 3 minutes, and rinse the sponge filter under running water. This washes off loose carbon dust before the filters go into the fountain.

How to change the filters
- Unplug the fountain and lift off the top.
- Take out the used carbon and sponge filters.
- Soak the new carbon filter and rinse the sponge as above.
- Fit the sponge filter in its slot, usually around the pump inlet, then insert the carbon filter into its curved compartment.
- Put the top back, refill if needed and plug in.
