GROOKPET Pet Fountain Filter Replacement – 12 Filters for Large Dog Fountains, 6 Activated Carbon Filters + 6 Sponges, 3-Month Supply

The GROOKPET Pet Fountain Filter Replacement set gives you a three-month supply of replacement filters for your GROOKPET dog water fountain. This pack contains 6 activated carbon filters and 6 pre-filter sponges, designed to keep the water in your fountain clean and fresh for your large dog. Each filter combines activated carbon, ion exchange resin, and sponge layers to trap hair, fine debris, and impurities while improving water taste. The filters come individually packaged to maintain freshness and hygiene. Compatible exclusively with GROOKPET fountains, these replacements help ensure your pet always has access to cleaner water.

What's in the box?

You receive 6 filters and 6 sponges — that's a total of 12 pieces. The filters are the main cartridges that fit into the fountain, and the sponges act as a pre-filter to catch larger particles before they reach the carbon layer. With a recommended replacement every 2 to 4 weeks, this set lasts roughly three months. Each filter is sealed individually to prevent moisture or contamination during storage.

How does the filtration work?

The filter uses three layers: activated carbon for odor and taste improvement, ion exchange resin to soften water and reduce minerals, and a fine sponge to physically trap hair, dust, and other particles. This combination helps maintain water clarity and freshness between cleanings. Rinse the filter under running water for a few seconds before first use to activate the carbon and remove any loose dust.

Which fountains are these filters for?

This replacement set is designed specifically for GROOKPET dog water fountains. If you own a GROOKPET fountain with a 7-liter capacity (large breed size), these filters will fit perfectly. The model number is S14-6pcs. Check your fountain's manual or current filter size to confirm compatibility. This set does not fit other brands.

How often should you replace the filter?

For best results, swap out the filter and sponge every 2 to 4 weeks. If you have multiple dogs or the water gets dirty quickly, replace nearer the two-week mark. If the fountain is used lightly, the filter may last up to a month. Always rinse the new filter thoroughly before inserting it into the fountain.

Can you use these filters with any fountain?

No, these replacements are specifically for GROOKPET brand fountains. They are not universal. If you have a GROOKPET fountain (especially the large model with a 7L tank), they will fit correctly. The design and size are tailored to GROOKPET's fountain pump and basin.

Why use replacement filters?

Regular filter changes help remove impurities from standing water, reducing the risk of bacterial growth and keeping the water palatable for your dog. Clean water can encourage your pet to drink more, supporting hydration and overall health. The activated carbon also helps eliminate odors from the fountain itself.

Care tips

• Rinse the new filter under cool water for 30 seconds before installing.
• Replace both the filter and sponge at the same time for consistent performance.
• Wash the fountain bowl and pump per the manufacturer's instructions every week.
• Store unopened filters in a cool, dry place away from direct sunlight.
