Say Goodbye
to Filter Socks!

Enjoy maintenance-free aquarium filtration for months at a time.

The Klir Fleece Filter is a modular aquarium filter that automatically unrolls new material as it gets clogged, removing suspended particles from your aquarium and producing crystal clear water.



The Klir Filter eliminates the hassle of hosing, machine-washing and constantly swapping worn-out filter socks

The Klir Filter automatically advances new fleece material once it becomes clogged by suspended waste such as algae, food and other particulates.

Klir's filtration provides
three main benefits:

Results in crystal clear water filtered down to 50 microns — double the filtering capacity compared to most filter-socks.

Waste is removed from the water column before it has time to breakdown, helping to maintain low nutrient parameters!

The constant chore of monitoring and swapping filter socks or other mechanical media every few days is eliminated for months at a time. Once the filtering media is exhausted, replacing it is a snap and economical.


1Fifty yards of fleece is housed on a supply spool then threaded across a tray and onto a collection spool. This positions the fleece material to intercept your unfiltered water.

2As the filter material becomes clogged, the water level in the tray begins to rise. Level sensors activate a small 12-volt motor which turns the collection roller, advancing clean material from the supply spool.

3As clean material is once again exposed, water is now able to flow freely, lowering the water level in the trays and deactivating the motor.

This process is repeated as needed, allowing you to forget about filter maintenance!
