I haven't had the chance to use them for any length of time yet. They did arrive real fast and the quality looks very good they fit the opening in my furnace. I am anxious to see how they preform when the air conditioning starts. Ask me in July about your filters then. Until then Have a Great day.
The product had far fewer pleats (and thus surface area), and flimsier construction than the MERV 12 version of the leading brand, though a little lower in price. So I'm a little skeptical on the relative performance.
They were able to make a filter to the deminsions I need and ship it to me very quickly. I no longer have to worry about making filters fit or where I will be able to find that odd size for my old house. Thank you!!
Company was easy to deal with and filters are very good quality for the price. I buy 12 at a time and change every 3 months so its something I don't have to think about again for a long time.
