Air Purification

Air PurificationIf you are interested in having better air quality in your home or your office, you may want to consider investing in an air purifier. Air purifiers are devices that remove dust and other harmful elements in the air, and they are especially useful if someone has respiratory problems, allergies or asthma. They are also very effective at reducing or eliminating the presence of second hand tobacco smoke, so they are a must in households with children where one or both of the parents smoke.

There are many different kinds of air purifiers out there, and many of them are marketed toward individual household use. Most of them tend to be cost-effective as well as environmentally friendly, since not only do they provide better air quality, but they also tend to consume little electricity. Some of the most common air purification technologies include UVGI (ultraviolet germicidal irradiation), activated carbon, photocatalytic oxidation, ionizers, liquid ionizers, ozone generators, as well as filter-based air purifiers.

When looking for an air purifier to buy for household use, you should look at whether the product is ENERGY STAR certified, and thus more energy efficient, as well as the type of filter, and how often it needs to be cleaned or replaced.
Also, in the case of air purifiers that use filters, the best choices are those that meet the HEPA (high efficiency particulate air) standards mandated by the U.S. Department of Energy, which guarantees that at least 99.97% of dust particles will be captured by the filter. When choosing your filter based purifier, be sure to check that the filter is actually HEPA compliant, and not just “close.”

Of the different types of air purifiers, ozone generators are not used in residential areas that are currently in use, since ozone, while very efficient at removing certain strong odors and purifying the air, is also very hazardous to human health if inhaled in large quantities.
