Review on XIMOON Replacement Filters Kit for Shark XFF350 XHF350 Navigator Lift-Away NV350, NV351, NV352, NV355, NV356, NV356E, NV357, NV360, NV370, UV440, UV540 - Hepa Filter + 2 Pack Pre-filter Foam & Felt by Megan Spencer

I have provided my model number. in the title because it wasn't listed in the model description. I have the model number 358. The filters appeared to be the same material and quality as the original. The bottom thin filter was about the size of a hair, I mean a hair. I didn't bother to cut it, it fit perfectly. And there was a 0.001 inch gap in the thick filter on the sidewall, which I don't think will make any difference. Because you can tell where the airflow is by looking at the old dirty one. Who would wash them for the price? I still hated doing it. I spend $20 a year and replace them every 6 months. I immediately noticed a difference in recovered performance! And I've tried to keep up with the cleaning of the originals. With that in mind, who wants to wait a day before you can put down the filters and wait for them to dry? There are 2 in this set, so even if I want to clean one set, I can pop in another set and get to work!
