Breathe Easier with an Air Filtration System

When we think of air pollution, our mind usually goes to the brown cloud of smog in the sky. But did you know that the air in your home can actually be just as dangerous? According to the U.S. Environmental Protection Agency, indoor air pollution is among the top five environmental health risks.

There are two types of air pollutants that can affect the air quality in the home:

Particulate matter is the type of pollutant most people are aware of – things like dust, smoke, pollen and animal dander. Also included in this category are dust mites, molds, bacteria, and viruses.

Gaseous pollutants come from sources such as gas cooking stoves, vehicle exhaust, and tobacco smoke. They also come from the use of household items like adhesives, paints, varnishes, cleaning products and pesticides.

If you’re worried about the quality of air in your home, relax and take a deep breath – there is help available. You can limit your use of gaseous pollutants in the home and you can be diligent about cleaning up after dust and pet dander. Chas Roberts, your Tucson air conditioning specialists, are here to present another option: install an air cleaning device.

  • Filters: Air filters clean the air by passing it through a filter that removes particles. The density of the filter material limits the size of the particles that pass through – the denser the filter, the smaller the gaps and the more small pollutants and particles it can catch. Filters are used as part of the home’s Tucson air conditioning and heating system.
  • Ionizing purifiers: These air purifiers use a method called corona discharge to create charged air molecules called ions. Most molecules in the air have a neutral charge. Molecules passing through the corona discharge electrical field pick up an additional electron or lose one. This gives the molecule a negative or positive charge, but it does not remain neutral. Once a particle is charged, it will attach itself to airborne particles and be attracted to anything with the opposite charge. Metal plates –some negative, some positive – within the purifier are charged to attract these particles and remove them from the air.
  • Ultraviolet radiation purifiers: Ultraviolet light causes certain micro-organisms to become sterile and harmless. UV radiation purifiers have a UV light that bathes the air as it passes through, eliminating the potential harm of airborne bacteria and viruses.
