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.
Buying experience was fast and easy. Only downside is that filters were received not individually wrapped. Im not sure if thats an error or due to buying a higher quantity than I have in the past but it would be nice for filters to be individually sealed until time of use.
