Review on Enhanced Rotator Lift Away Filters for Replacement by Draven Louton

Bought these for my 4 year old Shark Rotator Professional Lift-Away model NV501. It says that the HEPA filter can be washed, only washed once. Like most filters, they should be replaced every year. All filters fit perfectly! I've already noticed that my vacuum cleaner works better and blows out less dust. Make sure you clean the 2 top filters, cylinder one, every time you vacuum to maintain suction and prolong life. This is my favorite vacuum cleaner.
