Review on 🧹 Anewise Vacuum Filter for Shark Navigator NV350-NV357 | 2 Pre-Felt + 1 HEPA Filter | Compatible with XFF350 & XHF350 by Peter Green

I bought the kit in April 2018 and replaced the original filters. At the time of writing it was July 2018 and I have to say I am very impressed with the filters. With the original set, after 3-4 months of vacuuming weekly, I could see dust coming through the foam and onto the felt pre-filter. I could also see that the foam was exactly the same size as the cavity it was in, meaning it wasn't as dense. However, these filters are a lot better from my research: the foam is actually slightly larger than the cavity, meaning it's fairly dense (if not a little dense), which is REALLY good, meaning it goes through it a lot less Dust. I also checked out the foam myself and after 3 months of use (same normal cycle) hardly any dust came through. The felt filter is still almost in its original condition! The HEPA filter, which I haven't used yet, means I'm still using the original, but I'll be replacing them all soon as I feel the need. I will definitely buy them again should I need another filter change cycle.
