Lacking structural integrity

1. Two of three filters had all or sections of both ends buckled inward up to one half inch. This resulted in the almost paper thin outer supporting grid to have weakening bends.2.Compared to my real Ultravation filter with 21 visible filtering folds these have 17.3.The Ultravation has progressive filtering while there are no markings, I can find, on these filters.4.So how does one straighten out a deformed and structurally weak fiter to fit the airhandler bracket preventing air flow of "dirty" air from flowing around the edges?5.The undamaged filter may work "ok"!6.Contrary to your literature implications these filters are not true replacements . Sort of like an insurance company replacing a Dusenberg with an Edsel.
It's a filter. It fits. Not as highly rated at 11 as the traditional Honeywell at 12. Don't know that that makes any substantial difference. What else can I say about a filter?
