Satisfied customer

Needed to buy two more filters for our air filtation machine. Ordering was very easy, and the filters arrived promptly, and in good shape. We have them in reserve for when the current filter expires. We like our filtration machine, living here in Montana where we are now getting quite a bit of smoke from wildfires in the late Summer and early Fall.

Amazing filter for the Germ Guardian.....

I have a tall upright model of the Germ Guardian. This filter works awesome! It lasts a long time. I use my Germ Guardian in my classroom, and it helps in purifying air, removing allergens, bacteria, and general airborne germs in the classroom. I run the Germ Guardian all day long, and this is the first filter I have purchased for the unit.

Amazing

I bought 3 used Germ Guardian air purifiers off facebook marketplace about 8 years ago and they run 24/7/365. One gave up about 2 years ago but I have still been using the other 2. I've been washing and vacuuming them but finally had the money to replace the filters. I put them both in and within 5 minutes the house started to smell 100% better! I'll be so much better about replacing the filters now and when these 2 go out I'll replace them with newer models of the same one. I can't even say enough good things about them and how much better my house smells. (Three dogs and 17 cats over the last 10 years!)
