We love this filter, but now have two more boxes sitting in our hall closet. They work well and the perfect size. Had to stop automatic delivery, but we will order them again. Sandy

I have an IQ air purifier, I have a merv 11 prefilter, then 2 Merv 13 Filters stacked, Effectively giving me a HEPA filtration with good air flow.

What a reasonable price

I needed a new filter for my furnace, and the local big box stores and local hardware stores did not have my size. I looked on line and FilterBuy' s responses were quick and all was accomplished.

Perfect fit and my home stays pretty dust free even when I don't run the air purifiers.
