thought i had seen it all before. checking the furnace had low air flow at the grills and the sound of air being sucked aorund the furnace door, opened it up and there was a brand new filter installed, still in the plastic wrapper…
By the looks of it, I doubt the “Plastic” had much to do with “Poor Air Flow”----:lol:—:margarit:
It should last forever.
See what drugs do to ya!
It just get dirty again
Michael that was a high efficiency filter . stops those nasty particles from getting through lol
Lets be positive now
here is a question if you put a amprobe on the fan motor with a plugged filter would it draw more amps? or less
They were in a hurry because you were coming!
