The main filter had rotted so bad I had to find a replacement now.
Home Depot had one left of WEB AbsorberElectrostatic filters FPR 5.
It's good for cigarette smoke etc so it's better than what we had.
I was able to cut it with scissors to fit perfectly.
I then got to thinking about the teardrop windows and cut pieces of the same filter to pressure fit the screen area of the open window.
We always run the Fantastic Fan in the direction that moves the air, through the windows & through the roof.
Last night we ran it all night long and seemed to work just fine.
I would rather have a filter higher rated like FPR 13 but none are available at present time.
From now on these two pieces of filter will stay with the teardrop.
