We have these food safe foam filters made exclusively for us according to our specifications. They are not available anywhere else. The pre-filter surrounds the pump, preventing cat hair and debris from entering the pump. This greatly reduces the frequency of pump-cleanings and contributes to the longevity of the pump. Each filter lasts at least a year to two years, depending on usage and care.
Can be used in conjunction with the activated carbon filter.
