Review on High-Quality EnviroCare Replacement Vacuum Filters for Shark Navigator Lift-Away NV350, NV351, NV352, NV355, NV356, NV356E, NV357 - Includes 2 Foam and 2 Felt Filters, Plus 1 Hepa Filter. Perfectly Replaces Shark Part #Xff350 & Xhf350 by Bridgett Walls

Ideal for Shark Navigator. The originals just kept getting rougher - what black stuff is collecting in the filters? Looks like mold but cannot be washed off. These replacements removed any concerns in this regard. Also, 2 kits makes this a lot in terms of economies of scale (cheaper to buy). The HEPA filter snaps into place immediately. Using compressed air to clean the originals caused some wear and tear on the filter media, so replacing it was the right answer. Here.
