It's an air filter

Does what it should. Change it often. Gets dirty fast. It would be nice if you made this size with Carbon/Charcoal for filtering/reducing odors.

Just installed it for the first time.

So far easy install. I have a very tight area to install my filter so it being a little smaller than the actual size helps it go right in. I’ll let you know my thoughts in a month.

We used to use a nationally-recognized name brand filter. These MERV 13 filters are just as effective and efficient as far as we can tell and are a much better value.

They fit well, and work well. I love that they are made in the USA. I also like the reminders that it’s time I change and receiving them in the mail.
