General Aire MAC 2020 Air Cleaner

The General Aire MAC 2020 Air Cleaner is a dependable, whole-house air purification solution that targets allergy triggers and everyday dust at the source. Installed in your HVAC return duct, it filters the air every time your system runs, delivering consistent, quiet purification for households that want healthier air without extra noise or floor-space clutter.

Key Features and Benefits of the MAC 2020 Whole-House Air Cleaner

• Whole-Home Coverage: Mounted in the return air duct, it treats every cubic foot of air that passes through your HVAC system, eliminating the need for additional portable air purifiers.
• High Airflow Capacity: Rated for systems up to 1,400 CFM, the unit handles most residential furnaces and heat pumps without restricting airflow or straining equipment.
• Tool-Free Filter Changes: A snap-action door and molded thermoplastic handle allow replacement of the media cartridge in seconds.
• Filtration: The MERV-11 filter traps up to 65 percent of particles from 1 to 3 microns in size, helping reduce respiratory irritants like dust, mold spores, and pet dander throughout your home. The filter should be replaced every 6 to 12 months.
• Protects HVAC Efficiency: By capturing dust before it reaches coils and blower components, the MAC 2020 helps maintain peak system performance and can decrease energy costs.
• Durable, Compact Cabinet: A corrosion-resistant painted steel shell measures 22 x 22 x 7 inches, ideal for tight mechanical rooms, and weighs only 15 pounds for easy handling during installation.

Why Choose a Media Air Cleaner Over a Portable Purifier?

If you’re comparing options for a whole-house air filtration system, media air cleaners like the MAC 2020 offer a simple advantage: set-it-and-forget-it performance. Because the filter sits inside your ductwork, it works whenever your heating or cooling system cycles, providing consistent air cleaning without added noise or visible equipment in your living space.

Unlike portable air cleaner purifiers that must be placed in each room, a single MAC 2020 Whole Home Air Purifier covers the entire house, reducing clutter and ongoing filter purchases. The passive design also means no extra electricity draw or electronic part failure, just reliable filtration that aligns perfectly with routine HVAC maintenance.
