### ⭐⭐⭐⭐⭐ These are the best fitting and best working I have yet to find thus far
*by A***E on 6 June 2022*

I bought these in 2022 a pack of four, which I get before the old ones run out. I don't use my AC during the comfortable fall and winter and spring, I mean there is a good bit of down time on my AC. So these last a while. But when I ran low, I bought a four pack but another company I mistook for these guys. I should have just looked in my orders and re-ordered them, because tho I ordered the same size exactly, they are a bit too long and i can't close the back which is a real annoyance. Everything has to fit right. Well as soon as I am able I will re-purchase these even though I have the newer ones left. These are sturdy disposable filters rated merve 11, which is a great rating for those who have allergies. I toss them after a month (or longer if I don't use my AC or heat that much during the season).
