How Does an Air Purifier Work? Clearing the Air on Air Purification
HEPA Filtration
HEPA stands for High Efficiency Particulate Air, and it is a type of air filter commonly used in air purifiers. HEPA filters are designed to capture microscopic particles as small as 0.3 microns in size, such as dust, pollen, pet dander, and mold spores. The filter consists of a dense mat of randomly arranged fibers that create a maze-like path for the air to pass through. As the air moves through the filter, the particles become trapped in the fibers, allowing only clean air to pass through.
One of the main benefits of HEPA filtration is its ability to remove allergens from the air. Allergens like pollen and pet dander can trigger allergic reactions and cause discomfort for individuals with allergies or asthma. By capturing these allergens, HEPA filters help to create a cleaner and healthier indoor environment. It is important to note that while HEPA filters are highly effective at removing particles from the air, they are not designed to remove gases or odors. Some air purifiers may include additional filters or technologies to target specific pollutants, so it’s worth considering your specific needs when choosing an air purifier.
Overall, HEPA filtration is a key component in air purifiers and plays a crucial role in improving indoor air quality, especially for individuals with allergies or respiratory conditions.
Activated Carbon Filtration
An air purifier works by using activated carbon filtration to remove odors and chemicals from the air. This type of filtration is highly effective in adsorbing various airborne pollutants, such as formaldehyde, benzene, and volatile organic compounds (VOCs).
Activated carbon is a specially treated form of carbon that has a porous structure, allowing it to trap and hold onto these airborne contaminants. When air passes through the carbon filter, the pollutants become trapped in the tiny pores of the carbon, effectively removing them from the air.
In addition to adsorbing odors and chemicals, air purifiers with activated carbon filters are also capable of eliminating harmful gases, such as carbon monoxide and nitrogen dioxide. These gases can be particularly dangerous to individuals with respiratory conditions, so having an air purifier that can remove them can greatly improve indoor air quality and overall well-being.
With their ability to effectively remove various pollutants from the air, air purifiers equipped with activated carbon filtration are a valuable addition to any home or office, providing cleaner and healthier air for all occupants.
Electrostatic Precipitation
An air purifier uses a technology called electrostatic precipitation to effectively remove airborne particles and improve indoor air quality. Electrostatic precipitation involves the use of an electric field to attract and collect particles from the air.
Collecting Airborne Particles
Inside the air purifier, there are two plates: a positively charged plate and a negatively charged plate. As the air passes through the purifier, the airborne particles become charged. The positively charged particles are attracted to the negatively charged plate, while the negatively charged particles are attracted to the positively charged plate.
This process is highly efficient in capturing a wide range of pollutants, including dust, allergens, pet dander, pollen, smoke particles, and even certain bacteria and viruses. The collected particles can then be easily removed from the plates, ensuring continuous air purification.
Overall, an air purifier with electrostatic precipitation technology provides an effective and reliable solution for clearing the air of harmful particles, making it an essential device for maintaining a healthy indoor environment.

Ultraviolet Germicidal Irradiation
An air purifier is a device designed to improve the air quality in a specific space by removing airborne contaminants, such as dust, allergens, pet dander, pollen, smoke, and even viruses and bacteria. One common method used in air purifiers is ultraviolet germicidal irradiation (UVGI), which helps inactivate viruses and bacteria. When air passes through the air purifier, it is exposed to UV-C light, which damages the DNA or RNA of microorganisms, preventing them from reproducing and rendering them harmless. This technology is particularly effective against airborne pathogens, including influenza, tuberculosis, and coronavirus. By utilizing UVGI, air purifiers provide a significant enhancement to air purification, creating a healthier indoor environment.
In addition to UVGI, air purifiers employ various methods to purify the air. These may include activated carbon filters, which absorb odors and volatile organic compounds (VOCs), and high-efficiency particulate air (HEPA) filters, which trap microscopic particles as small as 0.3 microns. Some air purifiers also utilize ionization or electrostatic precipitators to charge particles and collect them on an oppositely charged electrostatic plate. These different technologies work together to improve the overall air quality, ensuring that the air we breathe in our homes and workplaces is fresh, clean, and free from harmful contaminants.
