I just received my 12 PG4612 filters shipped from Premium Guard in Nashville, TN. I have a strong suspicion that these may have been "salvage" from a recent storm or tornado in TN. Some of the filter boxes have cardboard residue on them, like from an outer box that got wet. But I inspected all 12: no rust, no dents and no rattles. All had plastic seals. The date code on mine is
24MHM15 3470. These didn't come in a regular carton of 12. They were packed loose in a shipping box. Packaging could have been better, but for 83 cents each, who can be picky?
