I was purchasing MEV 8 filters for years andwhen I purchased a new HVAC system four years ago I stepped up to 11.Great improvement in air quality and keepsMy system clean
The filters are as expected, good quality and even better price. Compare Filterbuy to the big home improvement stores and Wallyworld and nobody will buy filters from those places again.
MERV 11 Pleated Air Filters work best in my home because they capture many allergens present in any household. After 1 month's use, I vacuum the filter and am able to use it for another month.
