Now's the Time to Clean Your Furnace

WHAT ARE APRILAIRE'S COST AND MAINTENANCE REQUIREMENTS?
The initial cost of the Aprilaire Air Cleaner and the professional installation by your heating and air conditioning contractor is surprisingly low. Since there are no electrical or moving parts, there are no components subject to mechanical failure. This means no expensive service calls are ever required due to mechanical failure. And...it is the only high efficiency air cleaner to offer a lifetime limited warranty.
The Aprilaire Air Cleaner uses no electricity. The only operating cost is replacement of the filtering media, usually once a year, or up to two years, depending on blower operation. This simple, 10-minute replacement procedure can be easily accomplished by the home owner, or by the installing contractor.

NEXT STEP: CONTACT YOUR HEATING/COOLING CONTRACTOR
Aprilaire Air Cleaner Models 2200 and 2400 are designed for convenient installation by your heating and air conditioning contractor with any type of forced air heating/cooling system. Standard sheet metal installation procedures are followed. Because no electricity is used, no wiring is necessary - further simplifying installation. These Aprilaire Air Cleaners are mounted in the return air duct, horizontally or vertically, to meet practically every installation requirement.
The Aprilaire Air Cleaner Model 2250 is designed for installation where a single central return air duct is used. It is surface-mounted in the location normally occupied by the return air grille of the central heating/cooling system. It may be installed in the wall or ceiling, making it equally adaptable for use with closed or attic installations. The only visible part of the installed unit is the attractive aluminum grille.

Technical Notes: Whole house air cleaners remove only those airborne contaminants circulated in the airstream by the furnace blower. The Aprilaire Air Cleaner can be used for commercial applications. However, since concentration of contaminants may be greater than in a residential application, the maximum recommended airflow per unit is 1000 cfm, for a commercial application.

TECHNICAL FACTS PROVE APRILAIRE'S EFFICIENCY.

The American Society of Heating, Refrigeration and Air Conditioning Engineers (ASHRAE) sets the industry test standards for high efficiency air cleaner performance. Using the Dust Spot Efficiency section of ASHRAE Standard Test Procedure No. 52.1-92, at 1200 cfm, the Aprilaire Air Cleaner's average efficiency on a mixture of all (atmospheric air) particles is 60%, and increases to 80% efficiency as it loads.
The efficiency of any air cleaner varies with the size of particles in the circulated airstream. The Aprilaire Air Cleaner media, loaded with ASHRAE test dust, reaches 95% efficiency on particles of 10 microns, such as pollens. The smallest particle that can be seen with the naked eye is also about 10 microns in size.
