According to the American College of Allergies, 50% of all illness is aggravated or caused by polluted indoor air.
The Environmental Protection Agency (EPA) themselves declare that indoor air is anywhere from 2 to 10 times more hazardous than outdoor air.
The EPA also warns us that the indoor air quality is the United States’ number one environmental health problem.
Today’s homes and buildings are built air-tight, and contain a long list of pollution sources (see list). As a result, natural air-cleansing agents such as ozone and negative ions are kept out, while contaminants are kept in.
A recent study found that the allergen level in super-insulated homes is 200% higher than it is in ordinary homes.
According to Scientific America, a baby crawling on the floor inhales the equivalent of 4 cigarettes a day, as a result of the out gassing of carpets, moulds, mildews, fungi, dust mites, etc.
Most people spend well over 90% of their time indoors. In which case, indoor air is going to impact our health far more than outdoor air.
The EPA informs us that 6 out of 10 homes and buildings are “sick”, meaning they are hazardous to your health to occupy as a result of airborne pollutants.
