Buy the best for a New A/C unit !!

Great product for your AC. Filters out just about everything.

good

These filters arrived bent and unusable. I didnt discover this until I need one after the return date.

Has definitely helped w/ allergies of all types

I love paying for crushed filters.

Did its job.

It was easy to install. It is good for 90 days. I bought the 4-pack. I seriously thought I was going to have to bring over a repairman and risk getting him or myself sick with COVID-19 since I had already washed and cleaned the washable filters but it was still whistling. Fortunately, this seems to have solved the problem. No more whistling! Thank you so much!

After Covid struck my family I wanted a filter that would go above and beyond. I got my moneys worth. GREAT PRODUCT!

Ive tested a LOT of filters over the years for shop air filtration systems. THIS filter is the only one that gives very low flow resistance (lower than most MERV 8 filters) but, at the same time, it offers 94% filtration efficiency for particles > 0.5 microns. The secret is that this filter has about 2x as many pleats as every other filter Ive tested so it has about the same filtration area as a 4 filter. Thats how it gives the best of both worlds... low flow resistance like the cheap fiberglass filters and high filtration efficiency (MERV13) at the same time. I wont use any other filter from now on. Kudos to the 3M engineers who put this one together.
