hello; I really did not care for the fact that the filters did not have the merv rating on the filters . the covering on the filter bundle kinda indicated that they were merv 13 ; but I am not sure???? are they merv 13 ??? thanks for your attention.. JOHN
Filters good tight fit, however, would be helpful if they had a tab to grab on to pull the filter out. Ill probably have to cut hole in filters cardboard to get it out at its end of use
