How Do Air Purifiers Work?

Air purifiers are designed to improve indoor air quality by capturing or neutralizing airborne contaminants. They work by drawing air from the surrounding environment with the help of a fan and passing it through various filtration or purification processes.

The most common type of air purifier uses a three-stage filtration system, which includes pre-filters, HEPA filters, and activated carbon filters. 

Pre-Filters: Many air purifiers have pre-filters that are the first line of defense in capturing large particles like dust, pet hair, and pollen before the air passes through the primary filtration system. These filters typically use a mesh or foam material to trap larger particles, which helps extend the primary filter’s lifespan and improves the air purifier’s overall effectiveness.

HEPA Filters: HEPA (High-Efficiency Particulate Air) filters are mechanical filters made of dense, randomly arranged fibers that can capture particles as small as 0.3 microns with a high efficiency of 99.97%. These filters effectively capture common airborne pollutants like dust, pollen, pet dander, and mold spores. 

Activated Carbon Filters: Activated carbon filters are made of a porous form of carbon that has been treated to make it highly adsorbent. Adsorption is a process in which pollutants are trapped onto the porous surface of the carbon. Activated carbon filters are effective at trapping odors, gases, and chemicals, making them particularly useful in eliminating unpleasant smells from pets, smoke, or cooking.

The fan in an air purifier plays a crucial role in circulating the air in the room and pulling it through the filters. As the air passes through the filters, particles, and pollutants are trapped, and the clean air is released back into the room. 

This continuous process helps to improve the air quality by reducing airborne contaminants, creating a healthier living environment.
