Review on Crucial Vacuum Foam Filter Replacement for Shark Vacuums - Bulk Pack (4 Pack) - Model NV400 - Part # XFF400 by Jamie Jenkins

I love my Shark but buying replacement filters can be expensive. I decided to try these and am very happy with how they work. Although I washed my original filters as recommended, they don't clean well and you will find that the Shark doesn't perform as it should. I will buy them in the future.
