Choosing an Air Cleaner to Improve Air Quality? Here’s a Guide

If you or any of your family members suffer from asthma, chronic bronchitis or other allergies and respiratory conditions, you may want to invest in an air cleaner. Choosing an air cleaner depends on several factors, such as the amount of carpeting in the household and number of pets. To help you find an air cleaner that best suits your needs, here’s a rundown of the types of air cleaners available.

  • Mechanical filters: Mechanical air filters use a fan to push air through a screen of fibers that catches allergens such as pet dander, smoke and pollen.
  • Ozone generators: These devices create a large amount of ozone to improve a room’s air quality. They’re frequently used following fires to remove smoke from the air. They can cause nasal congestion and irritate the lungs of those with allergies and other bronchial problems, so these units are less effective in average consumers’ home.
  • Electronic filters: Electrical charges are used to attract allergens and deposit them on oppositely-charged collecting plates. If the filter doesn’t have these plates, the allergens will be deposited on room surfaces.
  • Hybrid filters: Hybrids combine the features of mechanical and electronic filters.
  • Germicidal cleaners: Ultraviolet (UV) light kills bacteria and allergens that come in contact with the cleaner’s UV rays. UV lights may be used with other air filters that employ fans.
  • Gas phase cleaners: Activated carbon granules remove volatile organic compounds (VOCs), cooking gases and other non-particulate pollution from the air. They have to be replaced once a month or more, as the filters get dirty easily. The thin filters are usually fitted in front of HEPA filters.
  • Whole-house cleaners: If your home is heated or cooled via ductwork, considering a whole-house cleaner when choosing an air cleaner might be best. Filters are inexpensive and remove dust and dirt from your HVAC system’s coils and ducts. Replace them monthly or every two months for best results.
