Waterbox 7" Filter Cup

The Waterbox 7" Filter Cup is a clean, practical alternative to traditional filter socks, designed to fit perfectly into Waterbox sumps that use 7" filter sock openings.

This filter cup drops directly into the sock holder and sits securely in the opening with no wobble or modifications required. It is commonly used for activated carbon, phosphate media (GFO), or other filtration media, offering excellent water contact while keeping maintenance simple and mess-free.

Silencer Compatibility

The filter cup is specifically designed to work together with my Waterbox 7" Filter Sock Silencer.
The four internal knobs ensure correct positioning and a perfect fit, allowing the silencer to sit centered and stable while further reducing noise and splashing.
