These filters are great and have a good combination of High filtration and don't restrict the air flow. You do have to change them more often than the typical every 3 months that your typical spun fiberglass filters call for, but the significantly higher filtration of the air in your home is worth it. My wife and son have severe allergies and after installing these filters, weve noticed a lower amount of dust in the home. These filters are for people who want serious filtration of their home.

Size is perfect. Not sure if the filtration is as good as I had hoped as I have bad allergies. The material does not seem to be as tight as the 3M filters I normally use. Time will tell

This is sized correctly. The filter seems to catch everything coming through. Looks disgusting after its 90 days, dog hair, dust, unknowns all trapped in its pleated filter. I used a reusable filter before and never had this much debris. I highly recommend this MERV 13 filter.

I love these filters. They are pulling more harmful air particles than any other filter I have tried. I feel much better now that I'm not sneezing and coughing all the time.
