The air we breathe should be free of any pollutants to keep us away from the breathing diseases. These days when pollution is on a high, making sure that the oxygen you take in is uncontaminated is requisite. HEPA Air Purifiers are one of the most effective ways to protect from health problems like breathless, asthma or cancer.
Air purifiers annihilate the air borne pollutants – dust, pollen or minute microscopic particles undetectable to the naked eyes. HEPA air purifiers are both used for commercial and domestic purposes. These first came into market in 1940. Then, they were used in labs to remove radioactive particles from air. Later, they were designed for cleaning air in hospitals, houses, airplanes etc.
The newer versions use one of the three ways to trap particles in a HEPA purifier. The first type of purifier is used to trap bigger particles. In these filters, particulate matter is larger in size than the holes of the filters like is the case in any other filtration process. Thus, bigger particles are not allowed to pass through them. The process when the pollutant gets deviated from the normal course, colliding with the fiber in the filters, and gets trapped while traveling in the air stream is called “impaction”. This is the second process that is used in purifiers. The last process is called “diffusion”. This technique traps the minute of all particles when they hit the fibers and removes them from the air, making the air surrounding you germ-free.
HEPA air purifiers are basically used to remove unwanted air particles and airborne pollutants. In fact, these filters can clean the air of the pollutants up to 99.97% with removing particles upto size of 0.01 micrometer according to some air purifier ratings. However, the purifiers need to be maintained in good condition if you want them to last long. Change the filters regularly and remove allergens, dust and pollen articles.
