Practical Advice About Hepa Air Filters

Posted on the June 6th, 2009 under Health

Isn’t it a bit confusing reading about all the different types of air-purifiers

that are offered in the marketplace

today? If you were to do a

search on the Internet for HEPA Air Purifiers you will be presented with

literally thousands of blogs, all of which sell a variety of air purification

machines. One of the most widespread

air-purification systems is a HEPA air purifier.

HEPA Filters

An acronym for ‘elevated efficiency particulate

arresting’, a Honeywell HEPA Air Purifier filter theoretically is capable of

removing just about 99.97 % of flying particles of .3 micrometers or better. These would consist

of general irritants and allergens like

earth, pollen, mold and germs. The

new True HEPA Air Purifier filter was

complete in the 1940’s for the period of the Manhattan Project by the US Atomic Committee

to put off the extend of airborne radioactive contaminants which were a

end result of atomic bomb testing. These were

completed commercially presented in

the 1950’s and HEPA became the registered trademark and a generic name for

greatly effective

filters. Over the years HEPA filters have been further developed to please a greater order for air purity not

just in homes but as well in a mixture of industries similar aerospace, electronic micro circuitry, biopharmaceutical labs,

as well as in office and commercial complexes. There are also Ultra-HEPA or ULPA filters

obtainable whose ability to filter

filth and additional contaminants is even better than HEPA filters. It filters out

99.99% of the contaminants.

Allergy Relief

True HEPA filters, are superb for removing all types of contaminants

that are bigger than .3 microns in range. One micron is

approximately one hundredth times smaller than the width of your hair. So, you can

visualize just how small .3 micron is and the

capability of this filter to be capable to trap

and eliminate such particles. Thus when buying a HEPA filter do make sure that you’re

buying a true HEPA filter and not a HEPA type filter as the efficiency of the later ranges from 25-95%, while true HEPA filter is

99.97% useful in removing flying particles.

In addition, HEPA filters afford a dry surroundings, ensuring the entire removal of the trapped

germs as it cannot survive in dry

situation. Several filters are chemically

treated to destroy microorganisms while others may include a germicidal

ultra violet light to do the same effect.

HEPA Air Purifiers are noisier than other filters because they apply a

motorized fan to suck in the air. On the other hand, when

purchasing the purifier one must be aware of the performance of the fan motor as a weak motor will not

be adept to draw in adequate quantity

of air for the purifier to be useful. The filter commonly

needs to be replaced each 12-18 months, depending on the use of the purifier. The life

duration of a HEPA filter generally ranges from two to five years.

Huge HEPA air purifiers are rated the finest in conditions of overall

performance and capability to filter out tiny particles.
