I liked the ease of ordering and the price value, and that these are MADE IN AMERICA, but when I received the filters, I noticed the pleats are not uniformly spaced (with the glue) and the edges are not glued to the sides allowing NONFILTERED air to flow through. Looking at other websites this seems to be a quality control issue. I have a box of 6 I think I want to return.
I change my filter every 3 months!So as soon as I replace the filter, I buy 2 more for the next 6 months.Probably should sign up for auto replacement but I prefer to monitor the dirt.
