I bought six filters but wont need them until next spring. We only need them when we run the a/c. Im sure they will be fine.

Ive been using Filterbuy air filters in my Lenox A/C unit for several years. They fit well and are effective. I had once tried Filtrete filters from 3M but they had a foam strip that made them very difficult to install and remove. After using one I learned that its best to cut/trim this foam strip before installing but Ill never buy them again, lesson learned!

Ive been ordering these for 6 or 7 years now and they work great. We have to big labs and it stops the dust and pet hair and smells. Use to use the mev-13 but the air didnt move as well, but the 11s work well and the price is good compared to buying at a local store.
