The quality of these air filters are much higher than the ones I was buying at the big box hardware store. They are more rigid and have a higher MERV rating at a lower price. I am using the initial one at the moment but it appears to be cleaning the air more effectively.
It was a very streamlined process buying the filters and having them shipped. It was easy to find what I needed also. I cant imagine anyone has a bigger selection of filters to buy from and they were logically arranged. And the prices seemed very reasonable.
I order custom filters because when the air comes on the filters suck up and make noise and when the air goes off they fall back down. I would like for them to be a bit thicker. I am satisfied with the filtering system though.
