Review on FilterBuy 17X22X1 Pleated Furnace Filters by Joel Young

**Update** All replacement filters looked perfect no gaps unlike the first set supplied. I can't write anything about the functionality because not a week has passed since the first filter from this new batch. I hope he does what he has to do. Thanks for the free replacement. Previous Rating All filters purchased were defective. There were gaping gaps between the filter on the outside of the case frame and the pleated filter itself so if one was installed air could flow right through it which would have defeated the whole purpose if there was a filter at all. I don't know why all four filters had the same problem, maybe it was a bad batch.
