The filters are for backup

The filters are for backup and won't be used for some time. I have a good filter in my furnace now but purchased it elsewhere so can't give a rating on the filter itself but the on line purchase went well and was done in a timely manner.

Exactly what I wanted for allergies and viral concerns. With the season changing I find I am sniffling more and when I come back in my home I find with the filter on my breathing improves quickly. This was the Merv level I was looking for.

Perfect for what I wanted

I wanted a higher Merv filter for viral concerns. I wanted to keep our circulating air as clean as possible. I feel there has been an improvement. Less sniffing and allergy symptoms. Even if I have some when were outside as soon as I come back in and the filter cleans the air ny breaching improves quite a bit. Works for me.
