What Can Cause Indoor Air Pollution?


There are many things that cause indoor air pollution in homes, offices, manufacturing and commercial buildings. A major cause is a heating ventilation and air conditioning system that is not working correctly for good indoor air quality (IAQ).

Major pollutants are:

  • Smoke
  • Pollen
  • Dust
  • Pet dander
  • Cooking odors
  • Volatile organic compounds

Air Circulation or Lack of Circulation

Heat pumps and air conditioners have fans that circulate air through vents. The pumps and fans must be functioning to move clean air in and filter out harmful pathogens. An HVAC system that works well will collect dust, pollen and other debris in the filter system.

Filters may be used to collect the dust or an ultraviolet system may be used to trap microorganisms that can cause allergies. Mold and mildew must not be allowed to grow in HVAC ducts since these pathogens can also be harmful when inhaled. House dust contains pathogens from microscopic organisms. These pathogens can be easily removed.

Dust and vacuum carpets, drapes and floors on a regular basis to improve indoor air quality. Keeping screened windows open to circulate fresh air in good weather also helps air quality.

Many cleaning products, hairspray and nail polish can give off harmful odors that pollute the air. Aerosol sprays release odors and gasses into the air. Bleach and ammonia based products also contribute to indoor air pollution.

Exhaust fans in the kitchen and bathrooms will help to reduce odors. Stoves should have exhaust fans to absorb odors, steam and smoke from cooking.

Humidity levels in your home should be balanced and controlled by your HVAC system with humidifiers or dehumidifiers, based on where you live. Mold, fungus and mildew grow in dark, damp conditions. Dust piles up quickly in dry environments.

Smoke Can Cause Indoor Air Pollution

Second-hand cigarette, pipe and cigar smoke can be dangerous to anyone who has to breathe it. People who smoke should do so outside, but this is a personal issue. Many smokers do not care if the smoke and stale tobacco odors permeate their homes even when it is a form of indoor air pollution. An HVAC system with good air circulation and ceiling fans may help.

Fireplaces and chimneys must be cleaned of soot and creosote. The flue damper must remain open at all times.

Pets Can Cause Indoor Air Pollution

Dogs and cats shed their hair. Many people are allergic to these loving animals because of the dander or specks of skin beneath their hair. The dander and hair can also get into the HVAC filter system.

People not normally allergic to pets may sneeze and cough if excessive pet hair and dander are on furniture and carpets. The best procedure is to continually remove hair before it builds up. Vacuuming carpets and brushing your dog or cat will help.

Commercial and industrial buildings

Various regulations require good ventilation in office buildings along with commercial and industrial buildings. These regulations include no smoking, comfortable temperatures and adequate air circulation. Removing mold, mold remediation, may be required for some buildings.

Asbestos used in flooring and lead paint should be removed from older buildings by professional services using hazmat equipment. Inhaling these substances as dust particles can lead to respiratory diseases including cancer.
