General Aire MAC-L Right Angle Air Cleaner

Meet the General Aire MAC-L Right Angle Air Cleaner, an inline, whole-house solution engineered to pull dust, pollen, and other airborne irritants out of circulation before they reach your living spaces. 

Designed for homeowners who want set-and-forget protection without sacrificing HVAC efficiency, this right-angle cabinet slips neatly into your return air duct and handles an airflow of up to 2,000 CFM whenever your system runs.

Key Features and Benefits of the MAC-L Right Angle Whole-House Air Cleaner

• Low-Pressure Drop Design: It’s engineered to handle a robust airflow (up to 2,000 CFM) with minimal strain on your blower, supporting energy-efficient heating and cooling.
• Right-Angle Cabinet: The convenient cabinet shape easily fits into tight mechanical rooms or basement corners where straight-through filters simply won’t, saving valuable installation space.
• Galvanized Steel Construction: Resists corrosion, dents, and air leaks for dependable whole-house air purification year after year.
• Easy Access Door: The front metal panel opens without tools for quick and mess-free filter changes.
• Opti-Fiber Media: The MERV-11 filter traps 65 percent of common air pollutants as small as 1 micron, including dust, pet dander, and mold spores, keeping your HVAC coil clean and your family breathing pollutant-free air. The filter should be replaced every 6 to 12 months.

Why a Right-Angle Air Cleaner Makes Sense

Many whole-house air filtration systems demand a straight stretch of duct that simply doesn’t exist in compact mechanical rooms. The MAC-L’s 90-degree configuration solves this puzzle by redirecting airflow, allowing installation directly where the return duct drops into the furnace. No extra elbows, transitions, or space-eating adaptations are required to achieve a cleaner airflow path, lower installation costs, and a professional finish with easy service access for future maintenance.

Thanks to its generous 25.75-inch depth and full-height media filter, the MAC-L offers ample surface area for particle capture without limiting airflow. Homeowners gain robust whole-home air purification while contractors appreciate a quick, frustration-free install that doesn’t compromise system performance.
