Great filters Shopping is easy - get any size you need in one place. Worth the price when thinking about traveling around to all the hardware and lumber stores to find out they dont cary 2inch fiters.

We put in a new heating and air unit in a couple of years ago. These filters do help to catch the cat hair in the house. A big difference between quality filters and cheaper filters. I love that I can buy these filters in different quantities. It’s a Win-Win!

Excellent filter, like the 2 inch think size, helps with airflow through the system and with filtering the air. Lasts longer than 1 inch thick filters.

I trust the filter is top quality. Additional information on MERV number selection would be appreciated. Most customers probably understand higher MERV number equals more filtration but does anyone understand how much is enough, or even too much? Better filtration comes with more resistance to airflow and more load on the blower motor. How would one determine when the airflow resistance becomes too great?

I accidentally ordered the non-carbon version when I wanted the carbon. The terminology of "allergy" threw me as I thought that would be carbon. Anyway, I called and they were super good about it and sent me the carbon ones, which would have been more expensive, at no charge. Better than good service so I am glad to give a good review.
