Comments about Trane/American Standard PERFECT FIT Washable Filter (BAYFTAH21W1A):
Usage is in a Air conditioner unit at our home. Good price for the filter, hope that it holds longer than what I think it will as it could have been made a bit stronger as the frame appears to be a bit flimsy. Time will tell on the durability of the filter through several washings.
Bottom Line Yes, I would recommend this to a friend
