Homeowners looking to improve indoor air quality are turning to whole-house indoor air cleaners – systems that purify all of the air in a home. These types of air-cleaning units are an effective alternative to using portable devices, which restrict home occupants who rely on them to a single space.

Types of air cleaners to use

There are many types of air cleaners available on the market today, which is good news for people who are sensitive to pollutants such as pollen, allergens and gases.

  • Filtration systems utilize more effective air filters installed alongside the HVAC equipment. Take caution when choosing a more efficient filter, however, because higher-efficiency filters that can trap smaller particles also may restrict airflow through air conditioners and heating systems.
  • Electrostatic technology charges pollutants, causing them to stick together. However, these types of systems may leave a thin film of pollutant-filled dust throughout your home.
  • Ultraviolet lights zap pollutants such as bacteria and mold, rendering them harmless.
  • Photocatalytic oxidation (PCO) technology targets gaseous pollutants, and when used in combination with UV lights, effectively controls odors.
Where to install air cleaners

When choosing an air cleaner, you can opt for an in-duct installation, where a separate air-cleaning unit with a dedicated blower draws a portion of air from the HVAC system, and then purifies it. You can also select over-the-coil systems, designed to specifically target your HVAC system to keep it free of pollutants.

For the most effective results when installing an air cleaner, homeowners should combine efforts to control the sources of pollution in a home, by removing elements that pollute; and ventilating the home, which will help to exhaust old, polluted air outside and supply a balanced amount of incoming, fresh air.
