Air Purifiers – Maintaining Health and Comfort Through Air Purification

Health Benefits

Air Purifiers Could Help Reduce Heart Disease Risk – According to a recent Chinese study (, student participants who used indoor air cleaners (air purifiers) were found to have a lower level of a stress hormones than student control subjects not using an indoor air purifier.

It is a well-known fact that elevated levels of air pollution or SMOG can be harmful to the heart. In a small study conducted in China, 55 healthy college aged students were divided into 2 groups.

One group of students was given actual air purifiers to use in their dorm rooms while the other group of students were give fake, inactive air purifiers.

Researchers then measured the amounts of contaminants both in the student’s rooms and outside their dorm room buildings. This level was recorded as fine particulate matter (PM2.5) which is a component of air pollution emanating from cars, trucks, factories, cigarette smoking, power plants and local fires.

The study found that exposure to elevated levels of PM2.5 increased student’s levels of stress hormones. According to the researchers, these increased levels of stress hormones triggered metabolic changes that could increase risk for heart attacks.

The researchers found that by using air purifiers, the indoor levels of PM2.5 was reduced by an average of 82 per cent and led to “short-term” declines in stress hormones. After 24 hours of using an air purifier, the PM2.5 levels were found to have fallen to a level within the World Health Organization’s (WHO) safe level.

Air Purifiers Help Those with Chronic Respiratory Diseases (COPD, Asthma) –In those suffering from chronic respiratory diseases, air purifiers have been found to decrease particulate matter (PM) quantity thereby increasing symptom-free days and reducing triggers for asthma attacks. This was found to be especially significant in children with asthma helping to filter out toxic particles and gaseous pollutants reducing “asthma morbidity.” (

Air Purifiers Help Those with Allergies – According to the US Environmental Protection Agency (EPA), the American Lung Association and the Institute of Medicine, air purifiers are recommended for those suffering with allergies. Using an air purifier can filter out many allergens which can trigger an allergic attack. These include allergenic particles like pollen, pet dander and dust mites. Irritating and noxious cigarette smoke can also be eliminated with an air purifier. Air Purifiers can also eliminate air borne, viruses, mold and DNA damaging particulates.

Air Purifiers Reduce Harmful Second -Hand Cigarette Smoke – Cigarette smoke has been proven to contain over 4000 dangerous chemicals and gases and at least 60 known carcinogens. In addition, tar particles in cigarette smoke can worsen COPD and trigger allergy attacks and chemical sensitivities.
