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 Brittany Ross

I have to admit that I am very embarrassed that I have never replaced the HEPA filter on my Shark Navigator Lift-Away Professional since I bought it 4 years ago. After looking at some reviews online I decided to purchase the EnviroCare filters and here are my observations: By comparing the parts to the original counterparts I can confirm that the HEPA filter is superior in design, fit and quality is almost identical (see attached photo). . Unfortunately, I cannot say the same for the felt filter, as it is much thinner than the original (see attached photo). I would advise not to throw away the original and clean up if possible. When I replaced it, I immediately noticed an increased suction power that the vacuum cleaner now has. You can also feel how hard the vacuum cleaner is pulling on the carpet pile. All in all, I think I've accomplished a lot thanks to Revain Warehouse. The parts, although repackaged, arrived well protected and in like-new condition, which saved me money. Absolute two thumbs up!
