WHAT YOU CAN'T SEE, CAN HURT YOU.
It's a fact: the trapped air we breathe in our homes can be loaded with dust, pollen, spores, and other pollutant particles. In many cases, it's worse than the air outside. Especially if you are one of the more than 40 million allergy sufferers in North America. Combine that with the fact that we spend 90% of our time inside and indoor air quality becomes a major concern.

Although most pollutant particles are so small that you can't see them, many are annoying or even harmful to you and your family, and potentially damaging to your furnace, air conditioner, and related equipment. The standard throw-away filter or electrostatic filter in your furnace traps only about 15% of the pollutant particles in your home's air. The rest circulates throughout your home.

Standard throwaway furnace filters and electrostatic filters permit dirt and dust to collect on sensitive heating and cooling equipment, decreasing efficiency by as much as 10-25%. The Aprilaire® High Efficiency Air Cleaner protects blowers, coils, and other operating equipment from dust and dirt, increasing efficiency and service life.

APRILAIRE® AIR CLEANER: THE PERFECT SOLUTION.
Installed in your heating/cooling duct system, central air cleaners with sophisticated filtering capabilities have become the accepted way to improve indoor air quality. And the Aprilaire High Efficiency Air Cleaner has proven to be the perfect, practical solution for whole house use. Absolutely silent operation, minimal maintenance, and 99% efficiency on pollen and spores, has made Aprilaire the clean air choice throughout North America.

In addition to providing protection for your heating and cooling equipment, the Aprilaire Air Cleaner provides your family with clean air throughout your home. A pollutant-trapping, equipment-protecting Aprilaire Air Cleaner will turn your furnace and air conditioner into a clean air system.

In fact, your home's furnishings will last longer. Carpeting and upholstered furniture will stay cleaner and last longer; draperies will need cleaning less often and last longer; walls will stay cleaner, too, and require less frequent painting, cleaning, and papering. And all this means less work for you. The Aprilaire Air Cleaner is an essential part of the Total Indoor Air Comfort System.

HOW DOES THE APRILAIRE AIR CLEANER WORK?
The Aprilaire Air Cleaner removes dust and other irritating particles from your home as the blower fan in your furnace draws them to the tightly sealed air cleaner. This clean air is then circulated through your furnace and back to the rooms in your home. The highly efficient HEPA-type filtering media (similar in principle to those used in hospital operating rooms and other clean room environments) allows The Aprilaire Air Cleaner to effectively trap a wide range of particle types and sizes. And the media becomes even more efficient as it collects particles.

The Aprilaire Air Cleaner also provides more than 72 square feet of particle trapping surface through its pleated design. That's the usable surface area equivalent to more than 31, 20" x 20" typical furnace filters. This feature allows the Aprilaire Air Cleaner to have a low resistance to airflow and a very long service life, typically one year or longer.

HOW DOES THE APRILAIRE AIR CLEANER HELP HAY FEVER & ALLERGY SUFFERERS?
Aprilaire is widely recommended by allergists, and these medical specialists understand the effectiveness of the high efficiency media in providing relief to their patients.

For most sufferers, hay fever and similar illnesses are a result of breathing pollen, molds, spores, or pet dander. Some of these particles can be as small as five microns in size. (See Particle Size chart below.) The Aprilaire Air Cleaner reaches 99% efficiency in removing these particles. This means practically all of the allergycausing irritants are removed from the circulated airstream. For continuous air cleaning during allergy seasons, your thermostat's fan setting should be placed in the "on" position.

To further determine whether the Aprilaire High Efficiency Air Cleaner can be beneficial in cases of hay fever or other allergies, consult your physician or allergist.

WHAT ARE APRILAIRE'S COST AND MAINTENANCE REQUIREMENTS?
The initial cost of the Aprilaire Air Cleaner and its 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.

The only maintenance required with Aprilaire is the easy replacement of the media.

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 closet or attic installations. The only visible part of the installed unit is the attractive aluminum grille.

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 1 micron, such as dust particles, and 99% 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.

TOBACCO SMOKE PROVES EFFECTIVENESS OF APRILAIRE.
Tobacco smoke is loaded with microscopic and submicroscopic size particles which can visibly stain fabrics, walls, and other surfaces. These unretouched photos of media used in homes graphically illustrate the high efficiency of the Aprilaire Air Cleaner in removing these tiny particles, and are typical of its performance in trapping other pollutants in the same size range.
