This was a mistake order by ME. Your team took great care of me and, I already have the correct 20x30x1 filters. Thank you so much.

merv 13 filters

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

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.

Keeping my ducting clean. I change the filter often. Great to have replacement filters on hand.

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!!
