Filters fit older air handler units
on December 8, 2023
Posted by: Katharine M.
I would have provided 5 stars but the first order was lost. This is the only company where we could locate the size needed for older air handler units. The price was appropriate and fit as it should.

fit is slightly small, but that's okay, cleans the air and I change it out every 3 months. I have no pets so this is the perfect filter rating. thank you

A far superior product to the filters I was using. They resist folding from the air being pulled through them.

Filter purchase

I wasn't able to find this particular size filter at my local store home improvement store 20x24x1. The quality of the filter was nice and sturdy,just what I needed. It fit perfectly inside my unit tray without bending or fixing. I will definitely be making additional purchase of this item.
