Helping with allergies.

I live in a very dusty desert, in a place where gardeners use leaf blowers every week. I change the filter every 2 months, and it needs it. This filter traps a lot of dirt that would be blowing on me. Made well, never had one fall apart.

2-Pack Great Value

I have used this product for years as it was recommended for my furnace. It has always worked well at trapping unwanted dirt and dust but lasting at least 3 months if not longer due to my forgetfulness in changing. The 2-pack is a great value!

Excellent for cleaning air of smoke particles!

I purchased these filters for the purpose of building a box fan air purifier, and once built, I was able to confirm an air quality improvement from 65 to 6 AQI in about 45 minutes for a large space, measured by a high quality meter from IQ Air. These filters worked very well for the purpose!

A good match

A good product that we use for our furnace. This brand works very well with our furnace and we continue to buy it. I've tried others, but they either block the flow of air or they don't block dust and the like. This product does both and does it well.
