STOP WASHING YOUR SOCK!

Now you have an alternative – the NOSOK™.

Nobody loves washing aquarium filter socks. And fleece rollers are complicated and hard to change. NOSOK™ is the filter sock replacement kit that is easier to clean than a filter sock, more effective and efficient than a filter cup, and less complicated than a fleece roller.

Simply Wrap the Filter Core with inexpensive filter floss and create filter sock-like performance without the hassle of washing dirty socks. When it clogs up, just toss the dirty floss and re-wrap it.

Increase the effectiveness of the NOSOK™ with the included nylon filter screen. The heavy duty, 255-micron nylon filter screen simply drops into the NOSOK™ filter cage . When it’s time to clean the screen, simply pull the screen out, it unrolls flat, and wash it under running water – it takes just a few second
