A Guide to Air Cleaners

Published by:


Indoor air pollution is one of the top five environmental health risks that we experience in our lives.  Generally, the best way to resolve this issue is to find and eliminate the source of the issue.  However, in most cases, you won’t be able to pinpoint the issue, nor will you be able to eliminate it, so the best case, the most common way, is to get an air filter in your home.

Many of these devices can be installed in the Heating, Ventilation, Air Conditioning (HVAC) unit in your home if you have central air, and will require the changing of the air filters regularly.  However, if you don’t have this and installing one isn’t in the budget, there are many portable units that you can get that will filter the air in your home, without being a climate controlling device at the same time.  The downside to this, is that these units are not a whole-home solution.

Indoor Pollutants

This is from the EPA website:

Pollutants that can affect air quality in a home fall into the following categories:

  • Particulate matter includes dust, smoke, pollen, animal dander, tobacco smoke, particles generated from combustion appliances such as cooking stoves, and particles associated with tiny organisms such as dust mites, molds, bacteria, and viruses.
  • Gaseous pollutants come from combustion processes. Sources include gas cooking stoves, vehicle exhaust, and tobacco smoke. They also come from building materials, furnishings, and the use of products such as adhesives, paints, varnishes, cleaning products, and pesticides.

Will a filter reverse the negative health effects of air pollution?

While it’s impossible to say that this will help in all situations, the main thing to keep in mind is that less air pollution, including dander, dust, pollen, smoke, etc. is never a bad thing.  Many websites will claim that a good air filter will be the end-all solution, and this simply isn’t the case.  You’ll want to consult a professional allergist, Pulmonologist, and HVAC serviceman in order to determine your how your results will vary.
