About this product
At an actual 19 7/8" x 21 1/2" x 3/4", the 20 x 21 1/2 x 1 Aerostar fits a return that doesn't conform to a standard nominal size - common in custom builds and certain regional HVAC markets where the installer specified a non-standard grille opening. MERV 8 handles baseline residential filtration. MERV 11 covers pet households and mild allergy concerns. MERV 13 captures fine particulates including bacteria, virus-carrying droplets, and wildfire smoke - the grade for households with respiratory health issues. Pleated synthetic media with an electrostatic charge built into the fibers handles the filtration. The pleats give you substantially more surface area than a flat fiberglass filter at the same nominal size, which extends the service life to 60 to 90 days under typical residential conditions. The electrostatic charge improves capture of sub-micron particles where the physical weave alone reaches its filtration limits. Manufactured by Con-Air Industries in Orlando, Florida. Cardboard frame, reinforced to hold shape under blower suction. Odd-size returns benefit from precise dimensional matching because a filter that's even slightly off-spec leaves a gap where unfiltered air can bypass the media entirely - the worst outcome if you're running a higher MERV grade to filter for health reasons.

- GENUINE DEAL
- A real low. Good time to buy.
- INFLATED
- Not a real discount. The 'was' price is not what this really sells for.
- TYPICAL PRICE
- Normal price. Fine to buy if you need it.
- NOT ENOUGH DATA
- Too new to judge. Not enough price history yet.
