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.

By reviewing the top air purifier technologies we hope to give you the information so that you can choose the right machine for your need.

An air air purifier works by cleaning the air of pollutants from the air in a home or workplace. We have reviewed the top 5 important air purifiers:

1.Ultraviolet Germicidal Irradiation (UVGI)-this kills germs contained in the air through UV irradiation. However, they are not considered to be highly efficient as most harmful bacteria and molds require a lot of UV light to be 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. Activated carbon is used to adsorb volatile chemicals at the molecular level. However, its efficiency is disputed since the adsorption process stops when the activated carbon reaches equilibrium with the atmosphere. Thus, not all chemicals are removed and chemicals can be released back into the air if there are more of them in the filter.

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. Other emerging technologies like Photo catalytic Oxidation (PCO) promise high levels of purification with low energy consumption. However, PCO is currently not being used in residential homes because they are ineffective in destroying gaseous pollutants.

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