Clean home
I feel like I immediately felt the air in my home cleaner. Our furnace has a built-in air purifier and my home was less dustier and it didn't have the usual after cooking smell that lingers for a day or so.

The filters came more quickly
The filters came more quickly than I expected and I appreciate the quality of the Merv 13 filters. I have 3 cats and 4 adults in my house so we generate a lot of hair and dust. This filter helps a lot! The price isn't too bad for 4 filters. Changing them out once every 3 months instead of every month is a blessing. I just set the reminder on my calendar. I just wish I could get all of the features the Merv 13 features along with the odor control but alas! You cannot have everything I suppose lol!

Awesome Filter and Recommendation!!!
The 20x23x1 filter fit is perfect. I was using the wrong size, per Tony (AC Tech). Tony(AC Tech) told me the filter size for the AC unit was wrong. The 20x22x1 filter I had inside the AC unit was wrong as well. He told me the right AC filter is 20x23x1 and gave me some tips for maintaining my AC unit as well. I would love for him to come back and give me more unit service tips as a user. In the meantime, I went out and purchased a basic AC service manual. . . . KUDOS to Tony!!!!!!
