4 Packs FLT4825 HEPA Replacement Filter B Compatible with AC4825 AC4300 AC4800 AC4900 AC4850, 4 True HEPA Filters & 6 Activated Carbon Pre-Filters

Bought these filters as replacements for Germ Guardian purifiers. Great quality and they fit perfectly! Thanks

The fold of the filter is much wider than that of the original manufactures. This allows more particles to pass through. The filters will need to be replaced twice as often, making the cheaper than the OM price irrelevant. I guess you get what you pay for. I will not be purchasing these again.

Replacing these filters periodically really helps the Germ Guardian do a great job filtering the air. I have purchased 3 Germ Guardians for my house and just recently bought a fourth for my Son who suffers from allergies in the summer.

This is the perfect replacement for the brand name version, and bonus their frame is made out of cardboard instead of nonrecyclable hard plastic.

These do not work with Germguardian HEPA Filters. They fit fine but my filter will not turn on with these filters installed. When I install the old filter it works just fine, the outer casing on these is cardboard while the originals are plastic. The appears to be two switches that have to be made up for the filter to function one for the filter installed and the other for the door shut. Can oly assume these filters do not trip the filter switch.

Nice buy for my air purifier. Seems to do the job so far. They did got my machine perfectly.

Super service I did not have to wait long to receive my order

Explained above. I need more time to add further comments

Fit great!

These filters are just as good as the Germ Guardian ones! I’ve been using these for years
