Air Treatment

This study covers the US market for indoor air quality equipment, which includes air treatment systems primarily designed to decrease the amount of airborne contaminants in residential, commercial, and institutional buildings. Historical data for 2010, 2015, and 2020 and forecasts to 2025 and 2030 are provided for indoor air quality equipment demand both in units and in current dollars (which are not adjusted to account for inflation).

Products in the scope of this report include central systems and local units (room-specific or location-specific, including those that are portable):

  • Central systems process air as it flows through a forced air heating, ventilating, and air conditioning (HVAC) system, or – as is the case with some mechanical ventilation systems – they operate in a central location in the building to draw air from throughout the home.
  • Local systems draw, treat, and circulate air in one room or localized area. Unless these units are installed for mechanical ventilation, they are generally portable and can be moved from place to place.

Also included are:

  • mechanical ventilation systems that can be sold separately from an overall heating or cooling system and are mainly intended to improve air circulation in a building by removing indoor air (which may have contaminants), bringing in fresh outdoor air; or a combination of the two
  • local units purchased by consumers for personal use outside of the home (e.g., during leisure activities, driving, work, or school)
  • replacement filters

Technologies used by indoor air quality equipment include:

  • air filtration, such as filtration with filters made from nonwovens (HEPA) or activated carbon
  • electrostatic air cleaners, including electrostatic precipitators and filters
  • ionic air cleaners
  • niche technologies, including ozone, ultraviolet (UV), and other smaller volume products

For systems with multiple technologies, the one under which a particular product is classified is determined by the primary level of treatment of that system. For instance, if a product includes both conventional filtration and UV, it is labeled as conventional filtration because that technology is more comprehensive.

Excluded from the scope of this study are:

  • air treatment systems that are classified simply as odor elimination products
  • air filters associated with appliances and HVAC systems (e.g., refrigerator air filters, HVAC filters, and automotive cabin air filters)
