Though coal was the prime reason for their invention during the industrial revolution, air purifiers or air purifier filters are now used at homes and in schools, offices, hospitals, and industries around the world.
Air purifiers and air filters not only trap mites and microorganisms, but also help asthma patients by providing fresher air. There are a wide variety of air purifiers and air filters available for every specific requirement of self-defence against polluted air.
Common air purifiers use air purifier filters. These systems work by passing air through filters with pores that are smaller than the dust particles present in the air. The dust particles are trapped in these filters made of fibers, and the passing air emerges dust-free. HEPA filters are most commonly used. Air purifier filters like MERV also enjoy widespread popularity.
Another air purifier technology that works by trapping particles makes use of activated carbon. Though fit for commercial use, these are very efficient air purifier filters that convert gaseous impurities into trappable solids.
Ionizer purifiers are also popular in the commercial sector. Ionic air purifiers work by charging the dust particles and subsequently entrapping the charged dust particles by charged plates. Ionic air purifiers are very effective. They come in two types: fan-less ionic air purifiers and fan-based ionic air purifiers. Noiseless liquid ionic purifiers are also available that require less power.
Another category of air purifiers use titanium dioxide to trap acidic and other noxious gases. Titanium dioxide air purifier filters are used in industries, and they employ nanoparticles of titanium dioxide along with calcium carbonate to neutralize such gases.
The most advanced air purifier or purification technology, perhaps, is ultraviolet germicidal irradiation (UVGI). These purifiers employ UV lamps through which air is passed, and aim at destroying microorganisms. These purifiers are massively used in laboratories, greenhouses, and fermentation units of every scale.
Everyone should have an air purifier. From prevention of sudden asthma attacks to keeping breathable are clean, air purifiers save us from many pollutants that we cannot see or feel. With pollution and population both on the rise, air purifiers and air purifier filters are here to stay. Use air purifiers so that you don’t have to think twice before breathing.
