Great filters Merv 11 and merv 13

I can definitely feel the difference with the Merv 13, the air is more pure and fresher, they are a bit more expensive but worth the expense. . imI also purchased Merv 11, but I will use those for winter time, they are also great, I had purchased them sometime ago.

Too small

I should have read more carefully. This is listed as 18x24x1 but in the description it notes the actual size is 17. 38x23. 38x0. 75". If Im careful it BARELY fits without getting sucked up but it took a few (frustrating) attempts. Size just doesnt work for our system. Will not be ordering again.

I love the recurring subscription, which is the best reminder to actually replace my air filters every three months. Otherwise, I'll never remember!

When new filters arrive, it reminds me to actually replace my air filters, otherwise I would forget. I just replaced them for the first time in six months and they were much filthier than I expected in such a short time. Now I'm on the 3-month train.

The filters are excellent; we noticed after the uses of a few filters there was not as much dust in the house
