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 reviewed the most popular air purifier technologies so you can find the purifier that is perfect for your household.

Air purifiers are devices that remove contaminants from the internal atmosphere of a building. There are various 5 main types of air purifiers:

1. UVGI – or Ultraviolet Germicidal Irradiation works by killing germs or bacteria using light wave radiation. UV are not the most efficient as removing bacteria and mold will require excessive amount of UV radiation before they are 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. The technology of activated carbon is based on the fact that carbon activated will adsorb pollutants on a molecular level. The efficiency of activated carbon is a bone of contention as once the carbon reaches equilibrium with the surrounding air then no more pollutants will be removed. If the amount of chemicals is high on the filter then some of these might be released back into the air.

4. Ionization purifiers do not use a paper or plastic filter like those seen in HEPA machines. Ionic purifiers use ions to charge the surrounding particles and then use an opposite charge plate to remove these pollutants from the air. The noise from Ionizer purifiers is a lot less when compared to HEPA purifiers. If you need to remove very small particles then Ionic are the perfect choice but are not so good at removing smells or bacteria.

5. PCO (Photo-catalytic Oxidation) might be a the major air purification technology in the future due to its promised efficiency for very low energy consumption. Currently PCO can not be used in homes as it has problems removing gaseous pollutants created during the reaction process.

We hope that these 5 reviews of the latest air purification technologies will help you to know which technology is right for your home.

After tests we found the Oreck XL range came out on top. Feel free to read more reviews of air purifiersthen please visit our new site.
