The value on these 20x22x1 AC and Furnace Air Filters by Aerostar is incredible! I normally pay around $11 for my home air filters when I’m shopping locally, so this set of six comes out at about half the cost. I was worried that at that price, there might be a big difference in quality.
I’m happy to report that these filters appear to be of identical quality of other brands I’ve paid twice as much for. It’s a great investment to buy a set and stock up! This set of six will take care of replacements for at least a year.
