Types of Air Purifiers and Its Functions Air purifiers are devices designed to clean circulating air by getting rid of contaminants and impurities in the air. Inside the air purifier are special filters, known as HEPA (high efficiency particulate air) filters, which clear the air by separating pollutants and impurities, like dust, pollen, pet dander, smoke, etc. Since air pollution has tremendously increased due to the rise of the carbon dioxide levels in the atmosphere, many related health issues have also been experienced, like allergies and asthma, such that in the US alone around 50 million Americans are directly affected by these health constraints, and, with that, concerns as to how to improve the indoor air quality are becoming a sought-after solution. Leading the pack in the advancements for cleaner air are air purifiers. The effect of air impurities, like smoke, mold spores, pollen, bacteria, viruses, pet dander, and pollutants, is to irritate the lungs and, eventually, lower the immune system. The advancements of filters, electric attraction or ozone have eliminated these air irritants by a high accurate percentage, helping to guarantee for a cleaner air environment.
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. Depending on the size of the room, air purifiers with HEPA filters have reached high efficiency use with tested proofs that the more times the air passes through the HEPA filter, the cleaner the air becomes. High graded air purifiers which have HEPA filters and 15 lbs of activated carbon or zeolite blends can effectively service 6 times air exchanges per hour and, at the same time, adsorb chemicals and odors that are inside the room. Some top-of-the-line brands of air purifiers have also ultra-violet light system which prevents the entry of viruses, bacteria, and fungi into the air purifier.
5 Key Takeaways on the Road to Dominating Services
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. For cost-minded consumers who would like to save from costly replacements of HEPA filters, the electrostatic precipitating cleaners or electronic air purifiers are also a good alternative since it functions by drawing in the airborne particles through an inside fan and charging them with a series of high-voltage wires. Another type of air purifiers makes use of electret filters which are actually special synthetic fibers that can create static charges which can attract air particles. Electret filters come in many forms, plain, pleated, disposable or reusable, and should be replaced when fully used. With negative ion generators, in it are tiny, charged wires or needles which produce gas molecules with negative charges or ions so that any airborne particles that enter the purifier immediately adhere to these negative ions and are collected in the filter. Ozone generators use high voltage electrical currents to convert oxygen to ozone, which acts as a powerful oxidant, breaking down the molecules and microorganisms in the air.
