Hazards of Indoor Air

can Indoor Air Be Hazardous to Your Health?

Poor indoor air quality (IAQ) can be the cause of numerous health problems. Medical groups report that as many as half of all illnesses are caused or aggravated by indoor air pollution. Pollutants in your home's air can cause dizziness, headaches and nausea, plus aggravate allergies and asthma.

According the Environmental Protection Agency (EPA), indoor air is two to five times more polluted than outside air. Given the fact that most people spend 90% of their time indoors, the EPA has ranked poor indoor air quality as one of the top five environmental risks.

Clean indoor air benefits everyone, even people who have never suffered from allergies. By removing airborne dust particles from the air, the amount of exposure the respiratory system has to them is greatly reduced.

Fortunately, there are several steps you can take to address potential IAQ problems:


The first step toward better indoor air is to identify the sources of air pollutants and remove as many as possible from your home. You can decrease the amount of dust and dirt in your home by cleaning and vacuuming at least once a week. You should also regularly wash bed linens and stuffed toys. If someone in your family is sensitive to fumes, you should safely store household products and use them only when necessary.


Today's modern homes are well-insulated and sealed to conserve energy, which means airborne pollutants have no way to escape. Lennox' ventilation systems help remove particles and bioaerosols by exchanging stale, recirculated indoor air with fresh, filtered outside air.


Although cleaning and ventilating helps reduce indoor air pollutants, these simple fixes are not cure-alls. Some contaminants are so small that they may escape through the vacuum or never land on a surface. Electronic air cleaners and high-efficiency air filters capture even the smallest of particles and bioaerosols. Germicidal lights kill them. And a Lennox air purification system goes a step further - it removes particles, bioaerosols and odors, and it destroys chemical vapors.


Improper humidity levels and high temperatures can actually increase concentrations of particles and bioaerosols. Thermostats regulate moisture levels and temperatures to improve indoor air quality and enhance comfort.
