December 14th, 2008

A HEPA air purifier is the ideal solution for allergy sufferers who need to breathe clean air in the home. Air purifiers were initially launched as tools to get rid of unpleasant odors in the home. However, these days you can get a lot of additional advantages from using a HEPA air purifier, such as better air cleaning capabilities and lower levels of bacteria and viral contaminants in the atmosphere. They remove pollutants and allergens from the air and let you breathe more easily. Additionally, a HEPA air purifier is perfectly safe for the environment, including your home and your children.

The Beginnings of the HEPA Air Purifier

The HEPA air purifier traces its origins to the year 1940. It was first produced at the time of the Manhattan Project, during which radioactive contaminants entered the atmosphere. As time went by, air purifiers, which originally didn’t utilize a filter, were continuously improved to address the need for better quality of air in our modern society.

Nowadays, you can find air purifiers in a variety of institutions like medical centers and industrial plants. HEPA air purifiers are used by the pharmaceutical industry, in nuclear plants, the aerospace manufacturing sector, health care facilities, and even in computer chips.

This highly functional tool claims a 99.99 percent reliability rating, and has proven to be an extremely helpful piece of equipment. Take a look at the testimonials found in just about any air purifier review, and you’ll see that HEPA air purifier reviews show that they are highly regarded just about everywhere.

How Does it Work?

The HEPA air purifier works in three ways: interception, impaction and diffusion. Because they are made up of randomly ordered fibers, they are very efficient with regard to their filtering capabilities. They trap airborne contaminants and all sorts of harmful particles that can lead to numerous illnesses and allergies.

The first step is the capture of a stream of air within one radius. The filters trap the air and the process starts. Impaction is next, meaning the larger molecules are trapped by the air cleaner’s fiber system. The molecules continually decrease in size as the air travels through the fibers contained in the system. Lastly, the air collides with other gas particles in a process called diffusion.

A HEPA air purifier has many advantages, but the most valuable is the efficient way in which it clears the air around us of of allergens. You can’t totally eliminate the contaminants in the air by using a HEPA air purifier, but you can definitely reduce them substantially.
