The NOSOK 7” Filter Sock Replacement Kit is a simple, low-maintenance alternative to traditional filter socks and oversized fleece roller systems. Designed for larger filter sock chambers, it gives you flexible mechanical filtration that’s easier to clean, easier to customize, and far less hassle to maintain.
Run the included reusable 255-micron mesh screen for long-term filtration, use filter floss for quick disposable maintenance, or combine both for a layered setup that captures even more debris before it breaks down in your system.
The mesh screen unrolls flat for fast cleaning and reuse, while filter floss provides an easy swap-and-discard option without dealing with dirty socks or complicated rollers. Together, they create an efficient filtration solution that keeps water cleaner with less work.
