PETKIT Fountain Filter Unit 5.0 Replacement Filters – 5 Pack

Fresh-Tasting Water for Your Pet

Keep your pet’s drinking fountain maintained with the PETKIT Fountain Filter Unit 5.0 Replacement Filters 5 Pack. Designed for compatible PETKIT EverSweet Max water fountains, these replacement filters help capture unwanted particles and reduce unpleasant odours as water circulates through the fountain.

With five filters in each pack, you have a convenient supply for routine replacement and ongoing fountain maintenance.

Multi-Layer Filtration for Everyday Use

The PETKIT Filter Unit 5.0 uses a filtration structure made from PP cotton and sintered activated carbon. These materials work together to help trap hair and fine debris while reducing unwanted odours and supporting fresher-tasting drinking water.

Regular filter replacement helps maintain the fountain’s filtration performance, but does not replace routine cleaning of the water tank, pump and other components.

Helps Capture Hair and Fine Debris

Pet hair, dust and other small particles can enter the water during everyday use. The filter helps capture this debris before it continues circulating through the fountain, supporting a cleaner drinking-water experience for your cat or small dog.

For best results, rinse the new filter with clean water before installing it and follow the instructions supplied with your fountain.

Helps Reduce Unwanted Water Odours

The sintered activated carbon layer helps reduce unwanted odours and improve water taste. This can make the fountain’s circulating water more appealing to pets, encouraging them to return to their water source throughout the day.

Water quality and filter performance depend on usage, local water conditions and regular maintenance.

Designed for Compatible EverSweet Max Fountains

The Filter Unit 5.0 uses a rectangular filter format intended for compatible PETKIT EverSweet Max fountain models, including:

• PETKIT EverSweet Max Cordless
• Selected PETKIT EverSweet Max 2 / Max UVC models that use the rectangular P4171 filter

Important: Check your fountain’s exact model and filter shape before ordering. Filter Unit 5.0 / RECT is not the same as the round Filter Unit 3.0 (P4161) used in selected EverSweet 3 Pro and Solo fountains.

Easy Replacement and Routine Maintenance

Changing your fountain filter is a simple part of regular care. Switch off the fountain, remove the old filter and install the replacement according to the manufacturer’s instructions. Rinse the new filter thoroughly with clean water before use.

Clean the fountain and pump regularly, refill with fresh water and check the filter periodically to help maintain consistent performance.

Recommended Replacement Schedule

PETKIT recommends replacing each Filter Unit 5.0 approximately every 2–4 weeks, depending on usage and water conditions. More frequent replacement may be appropriate where several pets use the fountain or the water contains more particles.

Keeping spare filters available makes it easier to follow a regular maintenance schedule.
