PETKIT Fountain Filter Unit 3.0 Replacement Filters – 5 Pack

Fresh Drinking Water for Your Pet

Help maintain your pet’s drinking fountain with the PETKIT Fountain Filter Unit 3.0 Replacement Filters 5 Pack. Designed for selected PETKIT EverSweet smart water fountains, these replacement filters help reduce unwanted particles, odours and impurities in circulating water.

With five filters in each pack, you can keep replacement filters ready for regular fountain maintenance and support a consistent supply of fresh-tasting drinking water for your cat or small dog.

Multi-Layer Filtration Technology

The PETKIT Filter Unit 3.0 features a multi-layer filtration system designed to help improve water quality as it circulates through your pet’s fountain.

The filter combines several materials to support filtration:

• PP filter material: Helps capture unwanted particles.
• PP cotton: Helps trap hair and fine debris.
• Coconut-shell activated carbon: Helps reduce unwanted odours and improve water taste.
• Ion-exchange resin: Helps reduce certain dissolved minerals and impurities.

Together, these filtration layers help keep circulating water fresher and more appealing for everyday drinking.

Helps Reduce Hair, Debris and Odours

Pet hair, dust and small particles can enter a fountain’s water during everyday use. The Filter Unit 3.0 helps capture unwanted debris and reduce unpleasant odours, supporting a cleaner drinking-water experience.

For best results, replace the filter regularly and clean the fountain and pump according to the manufacturer’s instructions.

Designed for Compatible PETKIT EverSweet Fountains

The Filter Unit 3.0 is designed for selected PETKIT fountain models, including:

• PETKIT EverSweet 3 Pro
• PETKIT EverSweet 3 Pro UVC
• PETKIT EverSweet Solo 2
• PETKIT EverSweet Solo SE

Important: Filter shapes and fittings differ between PETKIT fountain models. This round Filter Unit 3.0 is not interchangeable with the rectangular Filter Unit RECT. Check your fountain’s exact model before ordering.

Easy Filter Replacement

Replacing the filter is a straightforward part of routine fountain care. Before installation, rinse the new filter thoroughly with clean water as instructed by PETKIT. Fit the filter correctly into the designated compartment, then reassemble the fountain and reset its filter-life indicator if required by your model.

Regular filter changes and routine cleaning help keep the fountain working as intended.

Recommended Replacement Schedule

PETKIT recommends replacing each Filter Unit 3.0 approximately every 2–4 weeks, depending on water conditions and usage. The compatible fountain or app may provide a replacement reminder.

The actual replacement interval can vary according to the number of pets using the fountain, water quality and operating mode.
