It’s now common to find air purifiers in both the workplace and home. Sufferers of asthma and allergies now use them to make the air easier to breath. Due to the sheer amount of different technologies it can be confusing when you decide to buy one.

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. One of the best things about Ionizer purifiers is that they don’t use a polymer filter like the HEPA air purifiers. The way that a Ionizer purifiers works is by using ions to charge the surrounding air and then using a plate that is oppositely charged to pull away any pollutant compounds. Ionic based purifiers are very quiet in operation when compared with HEPA technology. Removing very tiny particles is very easy with Ionization purifiers but have problems when trying to remove germs and 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.
