## Description

For a cat fountain used throughout the day, fresh replacement filters help capture hair and fine debris as water circulates. This UMOCUOY set includes six activated-carbon filters and six sponge filters, giving you a ready supply for routine changes.

The filters are designed for UMOCUOY, GIOTOHUN, HOOISE, ATMZIQXR, and IHOUONE stainless steel cat fountains in 74oz, 88oz, and 108oz sizes. They are also described as a match for a 2.6 L stainless steel fountain, so check your fountain’s model and the product images to select the right replacement.

## How to use it

Before installing a filter, soak it in water for five minutes to remove dust. Replace the filter every 2–4 weeks to help keep the fountain water clean. With six carbon and six sponge pieces, the set is intended to provide replacements over a 3–5 month period, the actual schedule follows the recommended change interval and your fountain’s use.

Each filter is individually sealed to keep it clean before use. When it is time for a change, remove the used filter and install a fresh one according to your fountain’s setup. Is a straightforward routine more useful than buying a single replacement at a time? This set keeps both filter types on hand for regular maintenance.

## Benefits

The filtration combines activated carbon, ion-exchange resin, and sponge. Together, these materials are designed to adsorb and filter hair and fine impurities, helping maintain water quality and improve taste. That makes the set useful for households where a cat drinks from a fountain daily and the water is continually recirculated.

The two filter components serve different parts of the process: the sponge catches debris, while the carbon and resin contribute to water filtration. Having replacements ready makes it easier to follow a consistent change schedule without waiting until the current filter is due. Buyers commonly praise the fit, ease of installation, and filtration, some report changing filters sooner than the recommended interval, so use the 2–4 week guidance as a routine reference.
