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

To filter out the dog smell during winter I purchased an air filter which this product fits perfectly! This filter I am replacing every 4-6 months. Easy as pie!

This fit great, and I will be buying more. It was the cheapest I could find that I knew would fit based off of other reviews.

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

I liked that this one is the real product that actually fit into my air purifier. The price fluctuates every so often. It works as it is supposed to.

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.

I was glad to find a replacement filter for my air purifier. It was super easy to install and works great.

Some last a bit more than six months and others just four. It depends on the allergens in your air.

Great price and easy to order.

I put the new filter in and the red light keeps flashing. Why is this?
