You will now find that air purifiers are found in most homes and even some workplaces. People who suffer from allergies and asthma now use purifiers to clean the air so they can breath easy. When you want to buy on, the sheer amount of technology can 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. 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) air purifiers work by trapping pollutants using a fine filter ( efficiency is around 99% of particles sized 0.3 micrometer blocked as well as other smaller pollutants). If you want to maximise the efficiency of HEPA then you should use them in a situation where air is not circulated. Airtight rooms where air is only allowed through particular ducts is perfect for HEPA but its unlikely that this will be the case in an average US home.

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. Ionic air 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. 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.

Once you have read our reviews of the top 5 technologies we hope that you will find it easy to choose which technology is right for you.
