VCA NOSOK Filter Sock Replacement

STOP WASHING YOUR SOCKS!

Now you have an alternative – the NOSOK™ Filter Sock Replacement Kit.

Nobody loves washing aquarium filter socks, and fleece rollers can be complicated and expensive to maintain. The NOSOK™ offers a simpler, more effective solution that combines the performance of a filter sock with the convenience of disposable filter floss — without the hassle of constant sock cleaning.

Simply wrap the reusable filter core with inexpensive filter floss to create filter sock-like mechanical filtration. When the floss becomes dirty, just remove it, discard it, and re-wrap the core in seconds.

For even greater filtration performance, each NOSOK™ includes a heavy-duty 255-micron nylon filter screen. The screen drops directly into the filter cage and can be removed, unrolled flat, and rinsed clean under running water in just seconds.
