Benjamin Franklin recognized the importance of fresh indoor air when he said he believed that no outside air is as unwholesome as air in a closed room that has not been changed. Today, the Environmental Protection Agency consistently ranks polluted indoor air in the top five list of environmental health hazards. HEPA filtration can go a long way toward improving the air quality in your Northbrook, Illinois, home.

The Dangers of Poor Indoor Air Quality

Indoor air can be up to five times or as much as 100 times more polluted than outdoor air. Because Americans spend 90 percent of their time indoors, protecting the indoor air quality (IAQ) is essential. Poor IAQ results in a number of significant health issues:

  • Drowsiness and lethargy
  • Headaches and dizziness
  • Nausea
  • Asthma and allergy attacks
  • Acute and chronic respiratory tract irritation and infections
  • Sinus infections, sneezing and coughing

Indoor air contaminants can be brought in from the outside or generated inside your home or business. Common inside sources of airborne impurities include pets, spiders and mites, tobacco smoke and dust. One of the most efficient ways to remove these unseen airborne particulates is with filters.

HVAC Filters

HVAC filters improve the quality of your indoor air, extend the life of your HVAC system, and help it run more efficiently. As air passes through your system, it picks up dirt and other airborne particulates and circulates them along with the conditioned air. When the air flows through the filter, the filter captures the contaminants and keeps them from clogging your equipment or recirculating through your system.

HEPA Filters

Airborne particles are measured in microns — the smaller the micron, the smaller the particle. The most effective filter for maintaining a high IAQ level is a HEPA (high-efficiency particulate air) filter. HEPA filters trap particles as small as 0.3 microns. The 0.3-micron size includes up to 99.97 percent of airborne contaminants. Initially used in the healthcare and biosafety settings, HEPA filtration is highly successful in capturing a number of indoor pollutants like pollen, mold spores, bacteria, dust, and lint.

According to The American Lung Association, particles of 0.3 microns are the most likely to enter and collect in the lining of your lungs. HEPA filters capture these invisible contaminants while still maintaining the proper air flow inside your home or business.
