Though they’re a bit pricey. Sigh. But they do the job and no one else will, my dog has zero interest in air filtration. He’s about the kong bone. Can’t say I blame him. Also these are easy to install and you can slip the old used filter in the box for easy cleanup as well. This is a concern cause you don’t want to drop a very used filter onto carpet, which I have in some rooms. That would be a very unfortunate outcome. That’s why it’s great to have a form fitting box to quickly toss the old filter in. One and done. That’s what I say.

Description is correct for this product.

Easy to use and match with current filter

Fit the germ guardian i have fine . Was the right one and had no problems . Work fine with my machine.

Ease of use

Says change filter when red light flashes. Red light continues you flash even after installing new filter. Why??

Filter fit and working properly. Thanks.

I purchased these for my home because my father was coming to visit and I also suffer from bad allergies and sinus infections. These definitely helped keep dirt and animal hair at bay. Last about 6 months before needing to be replaced.

I have used these for six years and I have no complaints

This is easy to install and works well.
