Getting The Best Air Purifier

To get the best air purifier for you is no mean task as there are a assortment of them and the technology behind them is also different. The job of an air purifier is to clean the air of all its pollutants and that would include allergens, particulates, gases, etc. following is a comparison between the three main sorts of air purifiers that are ruling the roost in the purifier market.

The most advanced of all the air purifiers is definitely the HEPA air purifier. A HEPA purifier is basically a polymer sheet with minute holes by which air can pass, but very little else can. In fact the holes are so small that we require a pretty large surface area for a reasonable amount of airflow. That is why most HEPA filters are arranged in the style of an accordion to provide max surface area in a limited space.

Some HEPA filters have larger pores to allow more airflow but they are supplemented through a further filter. There are electrostatic wands which captures the smaller particles that get by the larger holes.

HEPA purifiers are however more costly than other purifiers and they have to be changed from time to time. The period might vary from anything between 6 months and 5 years depending upon the manufacturer. There is also the problem of the noise produced through the motor that propels the fan inside a HEPA purifier.

A newer variety of air purifier is the ultraviolet air purifier. This use UV light to alter the DNA profile of microorganisms like bacteria and viruses, most viruses and a few bacterial are smaller than .3 microns and so would pass through the best of HEP filters. The problem with UV air purifiers is that they are ineffective against particulates and gases.

Ion generating air purifiers are the third assortment. The way these purifiers work is that they emit a stream of negatively billed ions. These ions in turn charge the particulates in the air. So when they come in contact with anything they just stick there. The problem with these purifiers is that the particulates stick to the walls altering the look of the room. Generally it is found that the wall around the unit is completely black. And since there is no fan the cleansing occurs only near the purifier.

The choice is difficult, but with more information and more adept knowledge you can take a prudent decision.
