Knowing about Various Types of Air Purifiers One measure of cleaning circulating air, which has contaminants and impurities, is through a device known as air purifier. Air purifiers are equipped with special type of filters, the HEPA (high efficiency particulate air) filters, which help in separating impurities, such as dust, pollen, pet dander, smoke, and practically all pollutants existing in the circulating air. Because of increasing carbon dioxide level in the atmospheric air, this occurrence has created the increase, too, of air pollution, which is the main cause of allergies and asthma, of which an estimate of 50 million Americans are affected on it, and which health-related companies have come up with devices that can improve the indoor air quality. Leading the pack in the advancements for cleaner air are air purifiers. Air impurities, like smoke, mold spores, pollen, bacteria, viruses, pet dander, and pollutants can cause irritation in the lungs and can sooner or later lower the immune system. Since these irritants cannot be seen by the naked eye, manufacturers have come up with measures to remove these by using filters, electric attraction or ozone.
Why Purifiers Aren’t As Bad As You Think
The advantage of HEPA filters in air purifiers is that it has a greater 99.9% accuracy of removing airborne particles which are larger than 0.3 microns, a standard unit for measuring air particles, where the naked eye can only detect 10 microns and above. With room air conditioners, it can only filter captured particles measuring 10 microns and up. The effectiveness of air purifier’s with HEPA filters, with respect to the room size, is such that the more times the air passes through the filters, the cleaner the air becomes. Upgraded air purifiers with 15 lbs of activated carbon or zeolite blends have higher effective results such that it can operate with an approximate 6 times air exchanges per hour and, at the same time, can also filter chemicals and odors that are trapped inside the room. With an installed UV (ultra-violet) system in the air purifiers, biological and viral contaminants, such as viruses, bacteria, and fungi are eliminated before entering the air purifier.
The Path To Finding Better Systems
Another technology utilized by air purifiers to trap airborne particles is through electrical attraction, to which there are three types: electrostatic precipitating cleaners, electret filters, and negative ion generators. Another efficient alternative for the costly replacement of HEPA filters is the electrostatic precipitating cleaners or better known as electronic air purifiers, which operate by drawing in air particles through a fan and charging them with a series of high-voltage wires. With electret filters in air purifiers, air particles are removed by allowing them to be attracted to synthetic fibers that have the capacity to create static charges. Filter of this type come as plain, pleated, disposable or reusable and requires replacement. Ionic air purifiers or negative ion generators make use of tiny, charged wires or needles to create gas molecules with negative charges or ions so that any airborne particles that enter immediately adhere to these negative ions and are collected in the filter. With ozone generators, they make use of high voltage electrical currents to convert oxygen to ozone, which acts as a powerful oxidant to break down the molecules and microorganisms in the air.
