Porens Cat Fountain Replacement Filters, 28-Piece White & Black Set with Pre-Filter Sponges

Porens cat fountain replacement filters are a 28-piece replacement set for automatic pet fountains, with 14 filters and 14 pre-filter sponges.

• Three filtering materials—cotton, activated carbon and ion exchange resin—work to filter hair and heavy metals.
• Each filter measures about 3.9 x 3.9 x 0.4 inches (9.9 x 9.9 x 1 cm) for a compact fountain fit.
• Soak the foam filter for 5 minutes before use.
• Replace the filter every 2–4 weeks as part of regular fountain care.
• The set includes white and black components.

Fresh replacement filters help maintain the filtration setup in an automatic pet fountain. This Porens set pairs the main filters with pre-filter sponges, giving you both components for replacement rather than a filter-only pack. It is made for fountain owners who want to keep replacement parts on hand and follow a recurring filter-change routine.

Which pet fountains are these filters compatible with?

Porens replacement filters fit automatic pet fountains with a 95 oz (2.8 L) capacity. Check your fountain model before choosing filters so the replacement set matches your equipment.

• The set contains 14 cat fountain filters and 14 pre-filter sponges.
• Both components are included for replacing the fountain’s filter parts.

What does the three-part filtration system do?

The filter combines a cotton layer, activated carbon and ion exchange resin to filter hair and heavy metals. The included pre-filter sponge is a separate foam component in the replacement set. Together, these parts provide the filter and pre-filter elements for a compatible fountain; the stated filtration targets are hair and heavy metals.

• The filters are about 3.9 inches long and 3.9 inches wide, with a thickness of about 0.4 inch.
• White and black components are included in the set.

How should I prepare and replace the filters?

Soak the foam filter for 5 minutes before using it, then replace the filter every 2–4 weeks. This gives you a straightforward preparation step and a clear replacement interval to follow during routine fountain care.

• Allow the foam filter to soak before putting it to use.
• Use the 2–4 week interval as the regular replacement schedule.

This set suits cat owners with an automatic 95 oz (2.8 L) pet fountain who need both replacement filters and pre-filter sponges. Its fit is specific to compatible fountain models, and its contents provide the two filter components needed for that replacement routine.
