Air Purifier Reviews

Technology is paramount to the efficiency of an air purifier and many different technologies exist. The first one that we are going to talk about is called Air Purifiers with HEPA. HEPA means [high energy particle arresting) and are a type of a filter that was originally created by the atomic energy unit in the United States! The filters work in the same way as most other filters. However HEPA have much smaller holes to trap the dirt particles. HEPA air purifier filters are created by a piece of polymer or paper with tiny holes that will trap any irritating pollutants. In order for HEPA to work efficiently you need a large surface area so that is why they are folded into each other like an according. HEPA filters work very well in trapping different sorts of air particles but the problem is that the filters need to be replaced fairly regularly.

When reading reviews for HEPA air purifiers, I recommend you check out the amount of air that the unit can pass through, the noise from the fan and how long you can wait before replacing the filter.

If you don't mind paying for filters on a regular basis then a HEPA based purifier is probably the way forward. When ever our site reviews HEPA based air purifiers we always base our overall score on the cost of the filters. In many cases the filters can cost more in one year than the actual unit, so it's worth finding this out before you invest in a new unit.

The next type of air purifier is called Ion generation which use negative ions to pick up pollutants in the air. This type of purifier was first used in United States submarines and is one of the most effective way of cleaning air. The other benefit of ionized air purifiers is that they don't require you to spend extra money of buying new filters. Like with all air purifier reviews, make sure that you compare different ion generating purifiers before you make your final purchase.
