VERY GOOD QUALITY

I have serious dust allergies and I have been using these in my bedroom HEPA filter for years. A much better value than name brand filters, work just as well, fit my unit perfectly.

We’ve used these filters in our BlueAir air purifier. They have a slight odor when they first start filtering but it dissipates quickly. They work really well!

The filters (individually wrapped in a plastic bag) came in a single outer shipping box that is very thin, and one of the filters is dented in a corner during transit. Blueair filters (and some aftermarket ones) are individually boxed in thicker boxes in addition to the shipping box to better protect them. These filters, while they fit, is not as snug inside as OEM and other aftermarket filters I've used prior - they slide in loosely and so the dimensions are a tad bit smaller. The weight of the filters is much less compared to OEM and previous aftermarkets used, so these filters, while they don't look and feel flimsy, are not constructed with heavier materials. But so far the filters are working (I hope), and hope per HEPA specs. There is no smell from these filters as received/installed.

A quality replacement for the basic 400-series air cleaner. Good fit, no odor, holds up well.

Well made filter

A set of two for the price of one. I love this. Filter is still going strong but the filter cartridge is so expensive for one. This one fits like a glove and it brings two for the price of one... I'm soooooo 😊 😃 😀

Same filter at a lower price
