BENEFITS
CLEAN, FRESH AIR YEAR ROUND Combines high efficiency particulate air cleaning (see Model AC-1) with the gas phase filtration (see Model AC-2) in a single cabinet for complete indoor air treatment. Removes dust, pollen, molds, tobacco smoke, grease, soot, bacteria, animal dander, airborne dust mites and other particle contaminants found in residential envionments for indoor air that is virtually free of airborne pollutants and irritants.
HIGH ARRESTANCE Filters out and traps 97% by weight of ASHRAE test dust that has particles ranging from .01 micron to 2,500 micron in size.
The microfilter media is rated at 75% average efficiency over the test period and actually improves in efficiency as it loads over the useful life of the media.

LARGE DUST HOLDING CAPACITY The 78 sq. ft. of air cleaner media (equivalent in size to a backyard swimming pool 6' x 13') provide one of the largest dust holding capacities available in high efficiency air cleaners today. The 62 sq. ft. of air cleaner media (as large as a 1-car garage door) provide one of the largest dust holding capacities available in high efficiency air cleaners today.
LARGE CARBON CAPACITY Holds almost 4-1/2 pounds of high quality, clean activated carbon pellets giving a much higher carbon loaded per sq. ft. of duct area than the usual slide-in throw-away filters-over 7,000,000 sq. ft. of adsorption area to do the job. N/A
LOW PRESSURE DROP The combination air cleaner/air purifier is designed to maintain low pressure drop and avoid interference with proper operation of heating and cooling systems. Handles up to a 5-ton unit (2,000 CFM). Designed to maintain low pressure drop and avoid interference with proper operation of heating and cooling systems. Handles up to a 3-ton unit (1,400 CFM) and is ideally fitted to today's smaller high efficiency furnaces.
ECONOMICAL OPERATION No costly electrical hook-ups, no yearly electrical operating cost. Simply replace the media as specified (See AC-1 and AC-2). No costly electrical hook-ups, no yearly electrical operating cost. Simply replace the media about once a year.
PROBLEM-FREE INSTALLATION Built-in flanges simplify connection to the furnace and/or duct work transitions. Built-in flanges simplify connection to the furnace and/or duct work transitions.
EASY MAINTENANCE The only maintenance required is changing the filter media about once a year. A Media Condition Indicator gage is included to let you know when media change is required. Carbon replacement is easy as well. See AC-2 for details. The only maintenance required is changing the filter media about once a year. A Media Condition Indicator gage is included to let you know when media change is required.
