Indoor Air Quality: What Causes Problems, And How To Fix It

Low indoor air quality is a problem in millions of households,and if left unchecked, it can cause major health problems with prolonged exposure. Asthma and allergy sufferers report worsened symptoms when they live in environments with poor-quality indoor air, and over time, occupants of a house with high levels of indoor air pollution can develop chronic respiratory problems and other serious health concerns.

The causes of low indoor air quality include:

  • Particulate matter - Inorganic airborne particles, such as dust and pollen, are a major cause of indoor air pollution. Dust also tends to build up in vents, registers and HVAC filters, which can worsen the problem by creating bio-nests while also putting undue strain on your heating and cooling equipment.
  • Toxic gases - Carbon monoxide and radon gas are potentially deadly indoor air pollutants. Carbon monoxide is a byproduct of appliance operation if you use a fuel source like oil or natural gas, and radon gas can seep into homes from outdoor soil.  Usually this occurs in trace amounts that are removed through the chimney or vent for these appliances.
  • Organic pollutants - Microscopic creatures can also pollute your indoor air. These pollutants include viruses, bacteria, mold spores and dust mites.

General strategies for fighting indoor air pollution include the use of exhaust fans in kitchens, bathrooms and laundry rooms as well as the promotion of proper air exchange. It is important that you let fresh air into your home regularly, and if possible, create a draft so that plenty of fresh air gets in while forcing stale air out. You should also vacuum, dust and mop your home at least once a week to reduce dust buildup.

You should supplement these strategies with the use of products that are designed to boost indoor air quality. Carbon monoxide and radon gas detectors should be mounted in your home, and you can also zap both particulate and organic particles with the use of appropriate UV light systems, air purifiers and high-efficiency HVAC filters.
