Why indoor air is more polluted than outdoor air?
We’re building houses, apartments, offices all very airtight to conserve energy. Without realizing, we’re also trapping pollutants. Such as pollution from wall paint, carpeting, household cleaning products, pet dander, skin flackes that we shed every second, germs and bacteria generated from sickness and disease, smoke, odor, mold and more. These trapped pollutants cause all kinds of health hazard including allergy, asthama, sinus headaque, sleep disorder and more.
