Product Details

Drop-in Self-Cleaning Filter that does not use electronics to keep its filter from clogging which causes suction drop – specifically designed to vacuum ultra fine powders. As soon as you turn on the vacuum the tight “but loose” material of the Flutter Filter beings to flutter and shake naturally. Constantly in motion, dry powders are kept from blinding its surface and causing suction drop. Any accumulation of debris that may occur on the surface of the Flutter Filter is naturally removed each time the vacuum is turned off and on

Inside the Flutter Filter is its floating filter cage which is also left to loosely swing, shake and knock itself against the material . . . helping to further ensure against filter blinding. Any accumulation of debris that may cake itself on the surface of the Flutter Filter is removed or released each time the Flutter Filter “pops up and drops down” — when the vacuum is turned on and off.

The completely natural self-cleaning filter uses no electronics, pulsations, levers or valves to keep dust, glue and debris from clogging and damaging the filter (including the HEPA cartridge filter.) The Flutter Filter is completely re-useable, washable and easy to maintain.
