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

I bought these because they’re half the price of the actual germ guard filters. They fit perfectly and they have been working great.

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.

Used for my germ guardian air purifier, no problems

They fit my unit and work great. I think I’ll add a subscription so they can shop every six months. Definitely buy these instead of the overpriced brand name.

love the product easy to use and very affective. cleans air well and filter last

Fit great!

these are great filters and they cost much less than the name brands, used them a few times now and saved $$$

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.

Good product

After installing the filter. The air purifier wouldnt turn on. Found that it wasnt hitting the safety switch correctly. So it wouldnt turn on had to put a shim on the bottom switch so it would work. I have 2 and had to do the same for both. Otherwise works.
