Lots of Air Cleaners to Choose From: Let These Factors Guide You

According to the U.S. Environmental Protection Agency, indoor air pollution is one of the top five environmental health risks. Your ventilation system is typically used to introduce clean outside air into your home. However, when there are too many contaminants outdoors or the weather limits the effectiveness of your ventilation system, an air cleaner can help rid these pollutants from your home.Lots of Air Cleaners to Choose From: Let These Factors Guide You

Air cleaners, or air purifiers, are either built into your heating and air conditioning system, or are used as a portable device that treats an area or a room rather than your entire home. There are many machines available on the market, all of which tout being the best, so it’s important to know what to look out for before making a purchase.

Things to Look Out for in Air Cleaners

  • HEPA (high efficiency particulate air) filters: Trap tiny airborne particles such as dust and pollen, and are considered the most effective filter available. They are made from fibers that are randomly arranged and employ a three-step process to do the job.
  • CADR (clean air delivery rate): Using a numerical value, the CADR indicates how much air can be filtered and delivered from a portable machine, and the maximum amount of space it can treat. It also reveals how quickly it can get rid of pollen, dust and smoke. A higher number means it operates faster, but that number does not necessarily tell you how thoroughly it works.
  • “Asthma and allergy friendly”: Determines if a machine really works to lower the amount of allergens in the air rather than just redistribute them. This Asthma and Allergy Foundation certification is relatively new, and only a few air cleaners have been deemed worthy of the label thus far.

Please note: Some machines labeled as air purifiers produce ozone, a pleasant odor that’s released into your air. Be aware that ozone is considered a harmful lung irritant.
