These replacement filters are made for cat owners who want to maintain their NOBXBON wireless fountain and keep its water filtering system supplied with fresh components. The layered design tackles several types of unwanted material, from odors and heavy metals to floating hair and debris that could reach the pump.

How does the NOBXBON filter purify fountain water?

The cartridge uses a four-stage vertical purification system, with each layer addressing a different filtration task. Activated carbon adsorbs odors, while ion exchange resin softens water and reduces heavy metals. Ultra-fine non-woven fabric intercepts hair and particulate impurities, and the built-in pump sponge blocks debris to protect the water pump. The system is designed to provide oxygen-rich, sweet-tasting water and support your cat’s urinary health.

• Activated carbon targets odors in the water.
• Ion exchange resin is included to soften water and reduce heavy metals.
• Non-woven fabric and the pump sponge help intercept particles and debris.

What comes in the replacement filter pack?

Each box contains six filter cartridges and six pre-filter sponges. The detachable parts allow the cartridge and sponge to be stored and replaced separately, providing a set of replacement components for ongoing fountain care.

• The cartridges are also identified as carbon filters.
• The pre-filter components are sponge filters.
• The supplied set is intended to cover three months of replacement needs.

How do I prepare and replace a cartridge?

Before installing a cartridge for the first time, soak it for five minutes and rinse it for 30 seconds. Replace the cartridge every two weeks to maintain filtration performance. Homes with multiple pets should clean the fountain more often and increase filter replacement frequency.

• First-use preparation: soak, then rinse before installation.
• Use the two-week interval as the recommended routine for cartridge replacement.
• Increase cleaning and replacement frequency in multi-pet households.

This replacement set suits cat owners maintaining a NOBXBON wireless fountain who want separate cartridge and sponge components on hand. For stable operation of the NOBXBON fountain system, the brand recommends using official NOBXBON filters; non-official cartridges may not meet the product’s filtration standards or may cause fountain malfunctions.
