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

This filter helps the unit run as designed

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

Have used this in my mother in laws assisted living apt. She swears by it. Before she always felt she had allergies and it was dusty. Since we bought her this we have kept her in new filters whenever it tells us.

Great quality and perfect size!

Description is correct for this product.

This is the only filter for my Germ Guardian HEPA GENUINE Air Purifier. My local Target store never can keep a steady stock. Therefore, I thought of Amazon for my needs. The prize is perfect and better than what Target offer. Thank you Amazon for having this filter in stock. My allergy says, thank you.

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.

Works great
