upgraded the merv number of my current indoor heating and air vent. One thing in particular I notice is there is very little to no dust in my house. Thanks
Can't say much yet as I have only a week on the filter. I will know more in a month or three. So far Air flows through the filter nicely. I am looking forward to much less dust in the house with the merv 11 as opposed to the cheap filters I replaced. It was nice to be able to order the number of filters I wanted of the merv rating I wanted with a good explanation of what I was getting.
