🌬️ Aerostar 20x20x1 MERV 13 Pleated Air Filter - 6 Pack for AC Furnace - High Efficiency - Actual Size: 19 3/4" x 19 3/4" x 3/4 Review

I am amazed at all the good reviews. I just replaced my 3M filter with one of these filters and they probably have 20-25% more pleats in the material which means about 3/4 less area to filter.

I bought these to upgrade to 12x24. air intake. I buy aftermarket…

DO NOT BUY! YOUR HEALTH IS SERIOUSLY AT RISK if you suffer from immunological/allergic problems from mold, dust mite, etc. with these filters. They come with no packaging (plastic or otherwise), just in a box, which means that any dust mite (including the shipping box), mold spores, virus particles, bacteria, etc. will stick to both sides of the material and be automatically absorbed. down to your air intake and air ducts. I took a chance when my instincts told me not to use an unwrapped filter
