There are numerous kinds of air purifiers therefore a total information about air purification technology is excellent have, especially if you desire to get one but do not know which one to choose.
Hepa Filter Air Purifiers
Filter based air purifiers work by “filtering” dirt and allergens by size. Air is pushed from a fan through the filter and this one draws in tiny particles. The most basic air purifiers employ the use of cloth type filter to separate out the dust particles. HEPA or High-Efficiency Particulate Arresting filters tend to be the best filters that can trap 99% of the particles that happen to be 0.3 micros or larger in size. This device usually comes with a replaceable filter. Although a HEPA purifier can trap most suspended particles, it is ineffective against chemical fumes, odors and gases. Air purifiers that use filters are great at capturing allergens, however do not have the ability to trap smaller particles, like chemical gases, odors, smoke, etc.
Ionic Air Purifiers
Ionic air purifiers create charged particles (ions) and give off them in to the surrounding air. These ions blend with impurities (like dust) in the air, driving the impurities to hang on to a close surface. Ion generators are the second most common type of air purifiers, however they both emit ozone, an effective lung stimulant that is especially harmful for those who have asthma along with other chronic lung diseases, both children, and the seniors.
Carbon Air Purifiers
Activated carbon is treated with oxygen, opening up numerous pores in the carbon. There are various of these tiny pores that one pound of activated carbon contains a surface area of 60 to 150 acres. This huge surface area causes it to be ideal for absorbing gases and odors which happens to be too small to be caught by a HEPA filter.
UV Light Purifiier
This is basically a sterilization method using ultra-violet light. The UV light must be at the right wavelength which the best performing is 254 nanometers. At this wavelength the UV irradiation breaks the molecular bonds within DNA of microorganisms like airborne bacteria and viruses. This ruins them or makes them harmless. It also kills fungal spores and mold spores.
Ozone Air Purifiers
Ozone air purifiers work like an ionic however it is best on odors. Ozone is actually a remarkably reactive, unstable particle that oxidizes everything it comes in contact with. The ozone purifiers result in chemical reaction that breaks down the toxins, but the toxins turn into other pollutants, which unfortunately is the disadvantage to these machines. It’s suggested that you run the device on low, after which open the window to secrete the ozone.
Before you buy your air purifier you should ensure it fits your needs and conduct your own analysis.
