Air purifiers have become the standard household solution for eradicating air impurities. But what kind of particles do air purifiers can filter? Learn more about it below. 

An air purifier is a home appliance designed to cleanse and improve air quality. Back then, only medical facilities and clinics use air purifiers. Over the years, manufacturers introduced more efficient and budget-friendly air purifiers for household use. Today, you’ll notice that air purifiers have become a standard home appliance. 
Indeed, air purifiers support a healthy indoor environment. If you still have none, now is the right time to invest in an air purifier. You can consult this air purifier buying guide to learn how to find the best air purifier out there.

How does it Work? 
A standard air purifier consists of multiple filters and a fan. On the other hand, more advanced air purifiers have UV technology that kills microbes. 
The filters of this home appliance are often made of paper, fiber or fiberglass, and mesh. The multiple layers of filters capture the particles and pollutants in the air that passes through it. The first layer can capture particles of 1 micron in size and larger. The second and other layers of filters catch smaller particles to assure that air that goes out of the air purifier has zero contaminants. 
Manufacturers use different types of filtration systems in their air purifiers. Among these options, health professionals recommend High-Efficiency Particulate Air Purifiers (HEPA). This filtration technology can trap around 99.97% particulates larger than 0.3 microns. Hence, HEPA air purifiers are more efficient compared to an ordinary filtration system.

What Kind of Particles does Air Purifiers Filter? 
Standard air purifiers can trap common household particles measuring 1 micron and larger. These particles include dust particles, mold, pollen, and fur. These air impurities can be seen through the naked eye. 
A true HEPA air purifier can capture more particles compared to a conventional air purifier. Below are the different types of particles it can trap.

Chemicals and Fumes
A true HEPA filtration system can trap chemicals in the air and fumes using its highly porous activated carbon filter. The harmful chemicals and external pollutants it can filter include nitrogen dioxide and carbon dioxide. It can also trap vapor from cleaning materials, paint, and other strong chemicals. These pollutants are linked to health concerns like a tumor, cancer, and cardiovascular disorders.

HEPA air purifiers can filter particles up to 0.3 microns. These particles include bacteria, viruses, and microbes commonly present in the air. It can also filter out pathogens that cause airborne diseases, such as the common cold, flu, and respiratory diseases.

Filters Unpleasant Odor
The most advanced air purifiers can trap even foul odors such as tobacco smoke and cooking oil. The activated carbon in HEPA air purifiers absorbs all the smells keeping your home smelling fresh and clean.

Eliminates Radon
Radon gas is a by-product of radioactive elements such as uranium commonly found in building materials. This gas is colorless and odorless, making it hard to notice. Hence, you wouldn’t know that your family is already exposed to radon. 
HEPA air purifiers can trap radon gas using their activated carbon filters. It assures the air that circulates in the room is 100% clean and safe.
