Most homeowners in Bearbranch, KY, are shocked to learn that their home’s air is up to five times more polluted than the outdoor air. Poor indoor air quality can lead to worse allergies and asthma, chronic breathing problems and a variety of short- and long-term illnesses. Your home likely has these four types of indoor air pollutants.

Biological Pollutants

All homes contain some biological pollutants. These pollutants include bacteria, viruses, mold spores, pet dander, pet saliva, oil vapors and aerosolized respiratory droplets. An air filter with a minimum efficiency reported value (MERV) 13 and higher will trap nearly all biological pollutants in your home’s air.

Volatile Organic Compounds (VOCs)

VOCs are gases released by liquid or solid items. For example, dry-cleaned clothing can off-gas formaldehyde. Pressed wood furniture, adhesives, paints, cleaning products and upholstery coated in stain-prevention sealants can release volatile organic compounds. Improving ventilation, controlling sources of VOCs and using an air purifier will improve your home’s indoor air quality.


Smoke is a common indoor air pollutant. It comes from combustion activities, such as burning a candle, using a fireplace or an unvented space heater. It also comes from tobacco products. Smoke contains a fine mist of gases and tiny particles. The particles can enter your lungs and cause asthma, bronchitis or other lung diseases. MERV-13 and higher air filters can remove these particles.

Particulate Matter

Indoor particulate matter includes particles that are less than 10 micrometers in diameter. According to the Environmental Protection Agency, they can get deep into your lungs, where they cause inflammation that can turn into a chronic breathing disorder. Particulate matter can come from some hobbies, wood-burning stoves or fireplaces, tobacco smoke and cooking. High-efficiency particulate air (HEPA) filters in vacuums and air filters with high MERV ratings trap these particulates.
