Filter are fine

My previous purchase had 5 count and I use 2 at a time because I really need a 36″ so I have to install 2 x 18″ as the 36″ is not readily available.

It’s expensive

I’ve been using this product for years. Unfortunately, due to Covid-19 the places I would normally buy this item did not have. My system requires 2 filters. I am good through January 2021 before I have to reorder.I would recommend this product to others.

These air filters are good for the high air flow return just not a return that might be farther away from the a/c unit. We have pets so these filters help with that. This size was hard to find so I was glad to find a multi pack on Amazon. We all stay inside more than we use to so I wanted a filter that I can trust.

The pack is pricey, but I get about 1.5-2 months use out of each filter so the cost savings does add up even considering the air quality in your home after using it. The installation was a bit easier than the brands I got at the big hardware stores.
