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!!!!!!

I like everything about getting these filters!
The company is great, their responsive and fast, their website help me with all of the details so that I bought the right filter, I get them in the mail, they're made in the USA, and I can consistently get the same filters with the same rating and actually trust them that it's what they say it is. This is not true anywhere else.
