About this product
At 17 3/4" x 29 3/4" x 3/4" actual, the 18x30x1 Aerostar fits a nominal 18x30x1 return. Long-rectangle returns like this are typical on older furnace cabinets and some horizontal air handlers. Three MERV grades cover the residential range. MERV 8 is your baseline - dust, lint, pollen, no special filtration requirements. MERV 11 steps up for pet households or homes with mild allergy concerns. MERV 13 captures fine particulates including smoke, bacteria, and virus carriers, the grade to pick for households with respiratory health issues. Pleated electrostatic synthetic media handles the filtration. The pleats give you substantially more surface area than a flat fiberglass filter at the same nominal size, which is why this filter holds debris for 60 to 90 days under typical residential conditions. The electrostatic charge built into the fibers improves capture of sub-micron particles - the size range where mechanical filtration alone runs out of options. Manufactured by Con-Air Industries in Orlando, Florida. Cardboard frame, reinforced for shape retention under blower suction. MERV 13 in this depth wants a more frequent change schedule - every 30 to 60 days under normal load - because the higher filtration grade reaches its pressure-drop limit faster than lower grades.

- 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.
