Flo-X Filter 
Best performing filter you can buy, and the most convenient
Main filter incorporates a bonded two layer precision foam and proper density for maximum performance and filtration
Comes with 2 built-in foam Filterskins® to make the task of cleaning the filter as easy as peeling off the dirty Filterskin®! It is like having 3 filters in one, and you don’t even have to loosen the wing nut to remove the Filterskin®
With 3 uses out of one FLO® Air Filter, they are more convenient and economical than replacing with a cheap disposable filter even if you just threw it away after one use
