Did you know that your home’s indoor air may be more polluted than Los Angeles on a smoggy day? Cigarette smoke, dust, soot, bacteria, molds, carbon monoxide, formaldehyde, radon, pesticides, and vapors from scores of household cleansers and building materials are just some of the contaminants that may be tainting your home’s air.
“Sufficient evidence exists to conclude that indoor air pollution represents a major portion of the public’s exposure to air pollution,” states a report issued by the Environmental Protection Agency.
Indoors, air pollutants get trapped and build up, particularly in today’s air-tight, super-insulated houses. When pollutants accumulate, some concentrations can exceed 100 times outdoor levels.
High indoor humidity can be a serious problem, too. Humid air encourages mold, mildew, and bacterial growth, which are health hazards. In winter, condensation collects on windows and can damage paint, insulation, roofs, and exterior walls. And in summer, high humidity feels uncomfortable and strains air conditioning.
The best way to keep a house from building up toxins and humidity is to provide plenty of ventilation. In Fans & Ventilation Equipment, we offer buying and installation advice for heat recovery ventilators, whole house fans, ceiling fans, bathroom exhaust fans, and cooktop ventilators & range hoods.
