Indoor Air Quality

Air quality is important when you have health problems, especially when you or any of your family members have asthma, allergies, chronic bronchitis, emphysema or chronic obstructive pulmonary disease (COPD).  Breathing problems can dramatically improve by improving air quality, so installing HVAC equipment to purify the air in your home makes sense for family’s with health problems related to indoor air quality.

Indoor Air Quality & Health

Clean air is essential for good health, and this is especially true when it comes to indoor air quality. We spend close to 90 percent of our time indoors, whether at home, at work or in recreational environments.

Most people, however, are unaware of the effects that poor indoor air quality can have on our health. Studies have shown that the air we breathe indoors is often many times more polluted than outdoor air.

According to The World Health Organization, 30 percent of homes today contain enough indoor air pollutants to negatively impact our health. The US Environmental Protection Agency calls indoor air pollution one of today’s top four environmental threats.
