Review on Nispira Replacement Compatible Housmile Anti Mite by Gordon Turman

Good. As some other people have said, these filters are way too big for the plastic frame that comes with the UV purifier. The ones I have are almost 1/16 inch wider. So when you try to fit the corners into the frame, the whole center bends and you end up with gaps in the corners. That means they don't work as HEPA filters. great for those allergic to dust mites. I wish I had known this before I threw away one of the original filters that came with the vacuum. I used it about 10 times and it should have gone away but at least , it was getting closer to the frame. It just doesn't exist. What a waste of money.
