Where Comsmart Cat Water Fountain Filter with... fits in your dog's day
Three short notes on who this product suits, how owners use it and what they keep an eye on, with your vet as the person to ask about health questions.

About this product
This cat water fountain filter pack holds 8 replacement filters and 4 pre-filter sponges for the 84oz/2.5L Comsmart pet fountain. Each filter measures 4.8 x 4.8in and is made of a cotton layer, activated carbon and an ion exchange resin, which together filter hair and heavy metals. The pack is meant for owners of the 84oz/2.5L fountain who want spare filters on hand for regular changes.
Which fountain these filters fit
The filters work in the 84oz/2.5L pet fountain and do not fit the 95oz/2.8L model. Compare the model of the filter already in your fountain with this one before ordering, because the 4.8 x 4.8in size decides whether it sits correctly in the housing. A fountain of another brand or capacity is not covered by this fit.
Cotton, carbon and resin in the filter layers
Each filter is built from three materials: a cotton layer, activated carbon and an ion exchange resin. As water passes through, the filter catches hair and heavy metals. The pre-filter sponges sit ahead of the filter and take the larger debris, so the filter itself meets less of it.
What comes in the pack
The box holds 8 filters and 4 pre-filter sponges, and every filter and sponge is individually packaged and sealed. That gives you eight filter changes and four sponges from one pack.
Rinsing a filter before it goes in
Rinse the filter with water before use, then place it in the fountain. Change the filter every 2 to 4 weeks.
Keeping spare filters sealed
Store the unused filters and sponges in their individual sealed packaging until you need them, and keep the pack somewhere dry.
