Indoor air quality is an issue of great concern for many Australian households: the possibility that the air being inhaled in living spaces may be contaminated is a serious health and safety issue that homeowners simply can't ignore. One of the most effective ways most homeowners use to rid of harmful pollutants from their indoor air is air cleaners.
Air cleaners are generally categorised according to the technology used to remove hazardous particles of different types and sizes from the air. If you are looking for air cleaners to use in your home, you should have a clue about what's being offered for sale. Here is a sneak peek at the three basic types of air cleaners available on the market:
Ionic air filters: These air filters rely on static charges to eliminate hazardous particulates from indoor air. They normally generate negatively charged ions called anions that attract cations (the positively charged ions in the air particles). As the particles come into contact with the anions, they form ionic compounds, which are then removed from the circulating air stream. Given that most surfaces in any room, be it table tops, interior walls, floors, curtains, draperies, etc. are positively charged, the anions form the air filtration systems will be attracted to these surfaces. In some cases, ionic air filters come with a collector to trap the charged particles within the unit.
HEPA air filters: HEPA is an acronym that stands for High Efficiency Particulate Arrestance/Air. This type of filters can trap the tiniest particulates circulating in the indoor air. They are commonly used for filtering out mould spores, dust mites, pollen, pet dander, and even some bacteria. The particulates in the air are first intercepted as they pass through the filter and then separated through the process of diffusion. This makes it much easier for even the smallest particulates to be trapped within the fibres of the filtration system.
Carbon air filters: Here, activated carbon is used to catch particulates of chemicals, smoke and gases. As the air travels through the filter, the activated carbon "arrests" the gases and odours and then neutralises them. Carbon filters are not often used alone, and are typically used in tandem with other filters.
UV light air filters: With UV air filters, there's no actual filtration. Instead, these air filters use UV radiation to kill bacteria, moulds, viruses and other harmful microorganisms present in the air by breaking the molecular bonds that hold the harmful elements together.
