I finally found a filter that actually fits my furnace. I had to wrestle my last filter out of the slot. Bought 4 filters which should last until next year! Im happy to have found one that fits for a good price!

This product is exactly like the original equipment one I got from my contractor and at a much better price. Definitely will stick with them going forward

Upgraded to MAX Protection filters this year and am very impressed with the extra filters in MERV 16 so far. Not sneezing as often and getting less dust in my home. No regrets and highly recommend these filters.

Can't beat the price and quality, great bang for the buck !!! Cost one third of buying locally, and these are merv 11, the merv 8 locally cost more
