As our homes become better and better insulated, the indoor air quality becomes poorer and poorer as contaminates simply can not “escape” as easily.
To help create a healthier home, people are installing air purifiers in their home. Either as part of the HVAC system or as a stand alone unit.
An air purifier removes contaminants from the air in the home and benefits allergy suffers, people with extreme sensitivities, individuals in a smokers home and asthma patients.
HEPA technology is most commonly used in a home system. Did you know that the original HEPA filter was designed in the 1940s and was used in the Manhattan Project to prevent the spread of airborne radioactive particles? It was commercialized in the 1950s, and the original term became a registered trademark and later became a generic term for highly efficient filters.
The US Department of Energy states that HEPA specification requires removal of at least 99.97% of 0.3 micrometers airborne pollutants. They are easy to maintain (simply replace the filter when it is “dirty” and produce no by-products. (Other air purifier systems can generate small amounts of ozone)
HEPA filters have a mat of randomly arranged fiberglass fibers, with diameters between 0.5 and 2.0 micrometers. These filters work using the following three mechanisms:
Impaction follows a similar principle but the particles start building on top of each other.
Diffusion happens to the smallest particles, they are slowed down in the filter, then potentially trapped by either the filter itself or the impaction build up.
It is important to note that HEPA filters are designed to stop very fine particles effectively, but they do not filter out gasses and odor molecules. So smoking particles are trapped but the odor remains!
