Air purifiers are commonly used to improve indoor air quality and create a healthier living environment.
How does an air purifier work?
Air purifiers employ various technologies to purify the air. The most common types of air purifier filters include HEPA (High-Efficiency Particulate Air) filters, activated carbon filters, ionic air purifiers, UV-C germicidal lamps, and ozone generators. These filters and technologies work together to effectively remove airborne particles and contaminants from the air, ensuring cleaner and fresher air for you to breathe.
Types of air purifiers
HEPA (High-Efficiency Particulate Air) filters
HEPA filters are one of the most popular and effective types of air purifier filters. They are made from tightly woven fibers that can capture particles as small as 0.3 microns in size with an efficiency of 99.97%. HEPA filters are highly efficient in removing allergens, dust, pet dander, and other airborne particles from the air.
Activated carbon filters
Activated carbon filters are commonly used in air purifiers to remove odors, gases, and volatile organic compounds (VOCs) from the air. The activated carbon has a large surface area that can trap and absorb these pollutants, leaving the air smelling fresher and cleaner.
Ionic air purifiers
Ionic air purifiers work by emitting ions into the air. These ions attach themselves to airborne particles, causing them to become heavy and settle down. This removes the particles from the air, effectively purifying it. Ionic air purifiers are often used to eliminate allergens, dust, and smoke particles.
UV-C germicidal lamps
UV-C germicidal lamps use ultraviolet light to kill or neutralize bacteria, viruses, and other microorganisms in the air. These lamps emit short-wavelength UV-C light, which damages the DNA and RNA of the microorganisms, rendering them unable to reproduce or survive. UV-C germicidal lamps are particularly effective in preventing the spread of airborne illnesses.
Ozone generators
Ozone generators produce ozone gas, which reacts with pollutants in the air, neutralizing them and eliminating odors. While ozone can be effective in purifying the air, it is important to use ozone generators with caution as high levels of ozone can be harmful to human health.
