Indoor air quality describes how the air inside your home or business affects a person’s health, comfort, and ability to function. From temperature and humidity to poor ventilation, mold growth, and chemical buildup, there are a lot of factors that determine air quality. Good indoor air quality maintains a comfortable temperature and humidity level, proper ventilation to bring fresh air indoors, and pollutant control.
Yes, it is! Indoor air can be up to five times worse than outdoor air because allergens, dust, dander, and other pollutants build up and become trapped. These contaminants are then repeatedly circulated through your home each time your heating or cooling system cycles.
Standard one-inch air filters should be replaced once every 3 months or more often if you have pets or someone has allergies or smokes indoors. This is a simple task you can do on your own. If your system uses a high efficiency particulate air (HEPA) or media filter, you should only need to clean or replace it once every six to 12 months. Not sure which filter to get or how to replace or clean yours? Just give us a call.
Hot and cold spots indicate an airflow issue and can lead to poor air quality as the air becomes stagnant. If you’re suffering from hot and cold spots, you could benefit from zoning. It separates areas of your home and heats and cools them directly to ensure they’re receiving adequate airflow and maintaining a comfortable temperature. There are lots of added benefits that come along with zoning—learn more about them and let us know if you have questions.
Yes—there are a number of products that can help alleviate allergy symptoms:

  • Air cleaner—purifies and removes up to 95 percent of particulates by trapping and eliminating them
  • UV lights—eliminates mold that grows in the dark, cool inner coil of your air conditioner and keeps it from recirculating in your home
  • Air ventilator—replaces stale indoor air with fresh outdoor air to keep allergen and pollutant counts down

For custom solutions, talk to your Sabre technician—our experts are trained to make tailored air quality product recommendations.

The ideal way is to have an air ventilator installed, but if you aren’t ready to invest yet, you can:

  • Open windows on nice weather days to let fresh air indoors
  • Use kitchen and bathroom exhaust fans anytime you’re cooking or showering
  • Change your air filter regularly to remove contaminants and keep air moving
Yes! In 1989, NASA published a study of air filtering plants that help produce clean air. Researchers suggest that at least one houseplant for every 100 square feet is ideal. Well known purifying plants include Dracaena, Peace Lilies, and Chrysanthemums, to name just a few. They can eliminate extremely harmful pollutants found in your air such as formaldehyde, benzene, xylene, trichloroethylene, and ammonia. Plus, having a houseplant increases the amount of oxygen that flows throughout your home.
Volatile organic compounds (VOCs) are the gases emitted from certain solids and liquids. They’re often found in:

  • Paints
  • Candles
  • Aerosol sprays
  • Cleansers
  • Disinfectants
  • Air fresheners
  • Hobby supplies
  • Cooking fumes
  • Office equipment
  • Building materials/furnishings

Left untreated, high VOC counts can cause headaches, fatigue, dizziness, nausea, nose and throat discomfort, and other symptoms that can lead to health issues.

Yes, their dander spreads easily and can buildup in your air and ductwork. The best way to minimize dander is to keep your pets off of furniture, vacuum and dust regularly, and replace your air filter at the correct intervals.
