People have become ever more cautious about their health and surroundings, which is also evident by the rising amount of internet searches about air purifiers, their importance, use, effectiveness, and much more. This article will answer all the usual misconceptions you might have about Air Purifiers.

The Need For Clean, Breathable Air

The air quality significantly deteriorated as the world progressed through industrialization, and the breathable air was carrying all sorts of pollutants. There were seasons when the fogs refused to disperse, and people started having breathing issues due to the bad indoor air quality. Airborne Pathogens led to diseases like tuberculosis and pneumonia. 

In 1963, the world came to know of a device that could clean air thanks to Incen Air Company, an innovative company that later became IQAir Corporation. The design was simple, an input grille where the air is pulled in, an output grille, and some filters in between to filter the air that comes in.

To date, there have been many changes as designs evolved, and the air-purifying methods also saw some welcome changes. There are multiple brands of air purifiers that manufacture air purifiers of high quality using the latest technology.

The present models of air purifiers can remove dust, debris, smoke, pollen, odor, volatile organic compounds, strong smells, and other harmful chemicals effectively. Some air cleaners can also sanitize the air by using ultraviolet light and chemicals that can kill the airborne virus, fungus, mold, and bacteria, thereby reducing indoor air pollution. 

Are Air Purifiers Backed by Science?

EPA is the United States Environmental Protection Agency that works to protect human health and the environment they live in. According to EPA, air purifiers can help in reducing exposure to polluted air by cleaning it and removing large particles that can act as lung irritants.

The EPA has formulated a number of metrics like Minimum Efficiency Reporting Value (MERV), Clean Air Delivery Rate (CADR) Filter Performance Rating (FPR), and Microparticle Performance Rating (MPR) to ascertain the performance of respective air purifiers so consumers can make an informed decision.

The EPA also clearly states that COVID-19 cannot be removed from the air by using air filters but using a mask, other precautionary measures, and air purifiers can help in lowering the risk of becoming infected with the coronavirus. A Whole-house air purifier can easily cater to the needs of an enclosed space efficiently.

Indirectly, air purifiers are effective in protecting individuals from exposure to airborne disease-causing airborne particles. 

When health care professionals are asked, “are air purifiers effective in improving health,” they mostly reply that an air purifier effectively removes indoor air pollutants that act as the common triggers for seasonal allergies while also taking care of heavy smells.

Air purifiers improve the quality of air within a closed space or an indoor space by adding a layer of defense that removes dust, pet hair, pet dander, cooking smells, cigarette smoke, pollen, VOCs, among many other pollutants that cause respiratory irritation.

These materials usually remain in the air, and when anyone inhales them, they can develop allergies, including dust allergy, pollen allergy, smoke hypersensitivity, and other such allergies. An air purifier removes such allergic agents and provides high-quality pure air to its user.
