Great filter! Great price!
First of all, love my GermGuardian air cleaner! Works well, relatively quiet, bonus UV light. This is the OEM replacement filter which is exactly the filter that came with the unit and was around $20 when I purchased it. Compared to most other "name brand" models of air purifiers, that's really inexpensive. Great value in this unit. There is both a HEPA and charcoal foam filter. Pop out the old one and pop in the new one. Super easy! Improved air quality and some nice white noise for when you go to sleep, lol.

Replacement Filter — Easy to Install and Works Great!
We bought the GermGuardian Genuine HEPA PURE Replacement Filter B for our air purifier, and it has been excellent. It fits perfectly in our AC4825 model and was very easy to install — just a quick swap and it was ready to go. The air quality noticeably improved right after we replaced the old filter. It captures dust, allergens, and odors really well, just like the original filter. Plus, knowing it’s a genuine replacement gives us peace of mind about the performance and durability. Overall, a great product that keeps our purifier working like new. Highly recommend sticking with the genuine filters for the best results!

Great price for these really filters the air good but I was a little nervous. The second time I ordered them came in a different box and I was scared. I ordered the wrong item, but I didn’t.
