About this product
A nominal 17 1/2 x 21 x 1 return takes a filter at an actual 17 1/2" x 21" x 1", which is what this Aerostar is built to. Odd-sized returns in the 17 1/2 dimension show up in certain regional HVAC markets and on custom installations where the original installer used a non-standard grille opening. MERV 8 covers baseline residential filtration. MERV 11 handles pet households and most common allergen concerns. MERV 13 captures fine particulates including smoke, bacteria, and virus carriers - the grade for households with respiratory issues. Pleated synthetic media with an electrostatic charge built into the fibers handles the filtration work. The pleats provide substantially more surface area than a flat fiberglass filter would offer at the same nominal size, which is what extends the service life to 60 to 90 days under typical residential conditions. The electrostatic charge catches sub-micron particles where mechanical filtration alone reaches its physical limits. Manufactured by Con-Air Industries in Orlando, Florida. Cardboard frame, reinforced for shape retention under blower suction. Custom and odd-size returns benefit from dimensional precision - a filter that's even slightly off-spec leaves a gap for unfiltered air to bypass the media, which defeats the purpose of running a higher MERV grade in the first place.

- 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.
