Suspended Particles

  • The easiest and most effective short-term fix for an overabundance of dust, foreign particles, and mites is to vacuum regularly. Dirty carpets kick up all sorts of particles when they’re walked on, so be sure to keep them nice and clean.
  • Clean your cloth furniture and wash your sheets regularly. These surfaces are a lot like carpet in that they trap suspended particles until used, when they eject all those irritants into the air around you.
  • If you have a pet, brush it regularly to keep hair and dander shedding to a minimum. Of course, some dander in the air comes with the territory of pet ownership – but a little quality time with Sparky and a shed-preventing hairbrush will keep suspended particles from getting egregious.


  • When it comes to harmful gases, the two biggest offenders are cigarettes and fireplaces. Both can add tons of smoke to the air in your home, creating a hazardous environment for everyone exposed. The obvious solution for cigarettes is to avoid smoking indoors. The fireplace, meanwhile, should be used carefully with a well-maintained chimney and the flue fully open whenever a flame is burning.
  • The other big contributor to potentially harmful gases in your household is found in kitchen. Stoves and ovens (especially those that use natural gas) should have an exhaust fan above them to eject fumes from the indoor space.
  • Additional best practices for controlling gases include using natural products (such as vinegar) for surface cleaning and periodically running exhaust fans in your restrooms.
  • Biological Contaminants and Filtration
  • The easiest way to limit the number of biological contaminants in your home – namely dust mites, bacteria, and mold – is to keep its relative humidity in check. If it rises above 50%, bothersome bugs will grow at much faster rates. Use your air conditioner or, if necessary, a dehumidifier to control indoor air’s moisture content.
  • Choosing the right air filter for your HVAC system is an especially important aspect of home air quality. Generally, you’ll want to find a filter with a moderate MERV rating that’s high enough trap most pollutants, but not so high that it makes your HVAC system work less efficiently. See your system’s owner manual or contact a Climate Control Experts technician to find out which air filter will fit your system best.
