Frequently Asked Questions About Air

Cleanliness/Freshness of Air

Dusty, dirty homes at any temperature can cause feelings of discomfort to many people, especially allergy sufferers. Additionally, the air in today’s tightly-sealed, well-insulated and energy-efficient homes can become stale as the same indoor air is circulated and re-circulated. The fact is, with dust, pollen, pet dander, mold, skin flakes, chemical fumes, cigarette smoke, Radon gas and more, the air inside your home can be even more polluted than the air outside.

Air Cleaners

If you thought air pollution was just an outdoor concern, think again. The particles you see in a beam of afternoon sunlight streaming through the window only represent about 1% of the millions of airborne contaminants in your indoor air. Most standard fiber glass-mesh furnace filters only trap about 15% of these particles, leaving the other 85% to pollute your air, your furnishings, even your lungs.

Mechanical Air Cleaner

A Carrier MECHANICAL AIR CLEANER has a heavy-duty media filter that can trap up to 28 times as many particles as a standard fiber glass filter, including animal dander and plant spores.

Electronic Air Cleaner

A Carrier ELECTRONIC AIR CLEANER can capture up to 95% of all airborne particles — smoke, grease, bacteria and even many viruses. An electronic model works as a sort of magnet for undesirable pollutants. An aluminum mesh filter catches most of the large particles. The smaller particles pass through an ionizing section, where they receive an electrical charge so they are attracted like magnets to grounded metal plates. The collected particles are cleaned off the plates every few months with a garden hose or by popping the filter in the dishwasher. While the process may sound complicated, electronic air cleaners only use about as much electricity as a 30-watt light bulb.

Air cleaners can improve your health, keep your entire home cleaner, protect your valuable investments and save you the time and aggravation of constant dusting ventilators. Every home contains a certain amount of unhealthy gases from a variety of sources — building materials, the earth under your home, your heating and cooling system, and even people, who breathe out carbon dioxide. While today’s energy-efficient homes do a great job of keeping heated or cooled air in, they also seal in stale, recirculated air. A ventilating system solves the problem of stale air by bringing fresh air into tightly constructed homes without wasting precious energy.


HEAT RECOVERY VENTILATORS recover heat energy during the heating season; ENERGY RECOVERY VENTILATORS recover both heating and cooling energy year-round. Making a ventilator part of your home comfort system is like being able to open a window in every room even on the hottest or coldest days … without the drafts, the humidity or the high energy costs. It’s literally a breath of fresh air.

Here’s How They Work:

Fresh air is drawn through a pre-filter and into the core. Heating or cooling is transferred into the fresh air which is then distributed throughout the home. Indoor air stays heated or cooled while stale air and humidity, particularly from areas such as bathrooms, kitchens and laundry rooms, are exhausted. Carrier ventilators are controlled by a convenient wall-mounted control unit, and have three comfort modes. The recirculation mode recycles indoor air continuously and exchanges air only when humidity exceeds the desired level. This setting allows homeowners with baseboard heat to enjoy the advantages of a forced-air heating system. The continuous mode, replaces indoor air with fresh outdoor air 24 hours a day. The intermittent mode provides the greatest economy, with the unit turning on only when humidity levels exceed the desired level.
