I received the filters and placed two in my furnace. They look great and fit very well. Actually I will know more after a few months and see how they do.

Using as primary in take filter on top of my mini split in wood turning (very dusty each day) shop. Colleague had to replace his ruined mini split at four years. Mine is going strong year round since 2017, with yearly maintenance.

These filters seem to be very thin and cheap. I will not buy again. Please take me off of your list.
