Do Air Purifiers Really Work?
We used to think that the air outside is dangerous to our health a decade ago because of the increasing pollution caused by burning fossil fuels and common organic pollutants. As a result, we stay inside our house worry free and feeling secured.
Well, the truth is that the air inside your home is actually more polluted than the air outside. The United States Environmental Protection Agency’s Office and Development conducted a study and found that the levels of about a dozen organic pollutants inside homes are two to five times higher compared to the air outside.
Air purifier can remove the following indoor air pollutants:
1. Particulate matter
- dust mites
- particles created from combustion appliances like cooking stoves
- tobacco smoke
- animal dander
2. Gaseous pollutants come from the process of combustion and from using building products:
- cleaning products
- cooking stoves
- tobacco smoke
- vehicle exhausts
To better answer the question “Do air purifiers really work?”, we must first determine whether the United States Environmental Protection Agency (EPA) supports the use of air purifier.
According to the United States Environmental Protection Agency (EPA):
- Air cleaning may be useful when used along with source control and ventilation, but it is not a substitute for either method.
- The use of air cleaning devices may help to reduce levels of smaller airborne allergens or particles.
- While air cleaning devices may help to control the levels of airborne allergens, particles, or, in some cases, gaseous pollutants in a home, they may not decrease adverse health effects from indoor air pollutants.
- The use of air cleaners alone cannot ensure adequate air quality, particularly where significant sources are present and ventilation is insufficient.
- Clinicians frequently recommend that patients who have asthma or allergies use HEPA air filters in HVAC systems or in portable air cleaners.
- Regardless of how efficient and effective air- cleaning devices are in removing pollutants, a question still remains about their ability to reduce adverse health effects.
- An air cleaner’s ability to remove some airborne pollutants, including microorganisms, is not, in itself, an indication of the air cleaner’s ability to reduce health symptoms.
Now to answer the question “Do air purifiers really work?”, the answer is YES. But how well they perform will depend on the air purifier brands. While air purifiers are not enough to combat the air pollution inside our homes alone, the United States Environmental Protection Agency (EPA) still consider them as an option if the ventilation method is not applicable in some weather conditions or when the contaminants level outside is undesirable.
