MyfatBOSS 8+8 Pack Dog Water Fountain Filter Replacement for 3.4Gal/13L Pet Fountains – Carbon and Sponge Filters

This MyfatBOSS filter replacement pack is designed for 3.4-gallon (13-liter) stainless steel pet fountains with a deeper, wider drinking area. Each set includes 8 activated carbon filters and 8 sponge filters, providing several months of clean water for dogs. The multi-layer filtration system uses non-woven fabric, ion exchange resin, and activated carbon to capture hair and debris, soften water, and reduce odors, chlorine, and impurities. Ideal for large dogs and multi-pet homes, these filters help maintain a steady flow of fresh water.

Compatibility and What’s Inside

These filters are specifically compatible with 3.4Gal/13L stainless steel large pet fountains that feature a deeper, wider drinking area. The pack contains 8 carbon filters and 8 sponge filters, giving you 16 total pieces. For homes with multiple pets, plan to replace filters every two weeks or more often; for single-pet households, the pack can last about four months at a two-week replacement schedule.

How the Filtration System Works

The filter combines three layers: a non-woven fabric outer layer traps pet hair, dust, and large debris; an ion exchange resin layer softens water and helps reduce scale and heavy metal ions; and a high-quality activated carbon core removes odors, chlorine, and tiny impurities. Together, they help keep your dog’s drinking water cleaner and fresher.

Easy Setup and Maintenance

Before first use, soak each filter in water for 5 minutes, then rinse under running water for 30 seconds. This removes excess carbon dust and improves filtration efficiency. Simply replace the filters as recommended to ensure steady performance. The filters are washable and can be gently rinsed during replacement to extend their life.

How long does a pack of filters last?

For a single dog, replacing every two weeks gives you about four months of filtration from one 8+8 pack. In multi-pet homes, replace more frequently—every week or two weeks—to maintain water quality. The pack includes 8 carbon and 8 sponge filters, so you’ll have spares on hand.
