Review on Fette Filter Vacuum Filter Kit for Shark FLEX DuoClean HV390, HV391, HV392 - Compatible with Models #461FFJV390 & 464FFJV390 - Includes 1 HEPA Filter, 2 Foam Filters, and 1 Pre-Motor Filter by Eli Cooper

Works great! We accidentally started vacuuming the wet outside carpet but stopped before the water got into the motor. Little did we know the filters were saturated with water. The next time we used the vacuum we found that the filters had shed. After replacing all the filters, the vacuum cleaner was like new. The filters were easily replaced by my 11 year old. Much better than replacing the vacuum cleaner or worrying about not fully cleaning the mold!
