Air purifiers are now becoming common place in both the home and office. Allergy and asthma sufferers rely on them to help them breath easy. If you are looking to buy one, then the array of technology can at first be confusing.
We have put together a review of five of the latest air purifier technologies so that you can choose the right machine for your home.
Air purifiers are devices that remove contaminants from the internal atmosphere of a building. There are various 5 main types of air purifiers:
1. Ultraviolet Germicidal Irradiation (UVGI)-this kills germs contained in the air through UV irradiation. However, they are not considered to be highly efficient as most harmful bacteria and molds require a lot of UV light to be destroyed.
2. High Efficiency Particulate Air (HEPA) filters trap particulate matter efficiently (99% of all 0.3 micrometer particles can be trapped as well as a significant portion of smaller particles). The efficiency of HEPA filters is maximized when air is unable to circulate around the filter. This means airtight rooms that ventilate through specified ducts, which is not the case of most homes.
3. Activated carbon is used to adsorb volatile chemicals at the molecular level. However, its efficiency is disputed since the adsorption process stops when the activated carbon reaches equilibrium with the atmosphere. Thus, not all chemicals are removed and chemicals can be released back into the air if there are more of them in the filter.
4. Ionic purifiers do not use a polymer or paper like the technology used in HEPA units. Ionizing purifiers charge the particles so that they are attracted to the plates that are the opposite charge. Ionizer purifiers make a lot less noise than most HEPA based machines. Ionic purifiers are able to remove the very smallest of particles but are not so helpful with doors or germs.
5. Other emerging technologies like Photo catalytic Oxidation (PCO) promise high levels of purification with low energy consumption. However, PCO is currently not being used in residential homes because they are ineffective in destroying gaseous pollutants.
After reading our air purifier reviews you should choose an air purifier technology that fits your personal needs.
