Many people assume their indoor air is clean. The reality is that your indoor air is most likely dirtier than the outside air in every instance and may be affecting the health of you and your family members. Whether you live in an apartment, townhouse or single family home, an old home or are building a new home, there are many ways to protect and improve your indoor air quality.

Tips to Improve Indoor Air Quality

Below are some general tips for maintaining good indoor air quality in homes. The most effective strategy for reducing indoor air pollution is to eliminate or reduce the sources of contaminants. Effective ventilation is also important since it increases the amount of clean outdoor air, removes pollutants through filtration and helps reduce the build-up of excessive moisture. Some key tips include:

Minimize Chemical Pollutants

  • Avoid smoking indoors. Tobacco smoke contains thousands of indoor pollutants at high concentrations.
  • Minimize the use of harsh cleaners, solvent-based cleaners or cleaners with strong fragrances.
  • Certain activities, such as paint stripping, hobby soldering or gluing, painting, sanding and rock polishing, may create high levels of pollution and should be performed outside.
  • Choose low-emitting products that have been third-party certified and labeled by reputable organizations. Be wary of manufacturer claims of “no VOC”, “natural”, or “alternative”.

Keep It Clean

  • Buy machine washable bedding. Wash pillows, sheets, and comforters weekly to reduce exposure to allergens, including dust mites.
  • Place walk off mats at all entrances to your home.
  • Use high efficiency particulate air (HEPA) vacuum cleaners with disposable bags and microfiber cloths for surface dust removal.

Control Moisture

  • Keep homes dry. Control relative humidity levels to less than 60 percent, using dehumidifiers if necessary. Clean humidifiers frequently.
  • Repair all leaks promptly.
  • Run bathroom exhaust fans while showering.
  • House plants can improve indoor air quality by filtering carbon dioxide; however, if they are over-watered, they can encourage mold growth.

Ensure Proper Ventilation

  • Make sure that mechanical filters are in place, that they fit well and that they are changed periodically according to manufacturer’s instructions.
  • Use of home mechanical air systems, with good filtration, can control dust levels.
