3 Commonly Held Myths of HEPA Air Purifiers Busted
HEPA air purifiers are widely used in healthcare settings to eliminate airborne contaminants and control the spread of potentially dangerous infections. While these air purifiers are effective to a degree, they also have major limitations. The prevailing sentiment that they offer a "catch-all" solution to the problem of airborne contamination is quite simply not true.
With that in mind, let's take a closer look at three common myths about HEPA air purifiers:
Myth #1: HEPA purifiers capture all types of bacteria and viruses.
The truth is that while HEPA air purifiers are extremely adept at capturing and eliminating dust mites, mold spores, pollen and dust, they do not remove all types of bacteria from a room and they are not very effective at getting rid of small viruses. If a microorganism is smaller than 0.3 microns in diameter -- as many bacteria and viruses are -- even the very best HEPA purifier on the market will not be able to get rid of it. Busted.
Myth #2: HEPA purifiers eliminate odors.
In many hospitals and healthcare settings, harsh and caustic chemicals are used to sterilize surfaces, and many of these chemicals leave lingering odors in the air which are unpleasant as well as damaging to the respiratory tract. There are also many biological odors coming from patients and solied utility rooms and are very unpleasant. Some people mistakenly believe that HEPA air purifiers eliminate these smells and vapors from rooms, when in fact they do nothing to get rid of lingering odors. Activated carbon filters purifiers are able to eliminate odors, but they are not widely used in healthcare settings since they do very little to neutralize organic airborne contaminants. Busted.
Myth #3: Microorganisms trapped in a HEPA filter are unable to reproduce.
Again, this commonly held myth is simply not true. Because the microorganisms captured in a HEPA air filter are not instantly killed, they are able to breed and reproduce, which can actually lead to an increase in their population levels. Busted.
A new breakthrough known as plasma field technology offers a filter-less way to eliminate airborne contaminants and remove odors. A plasma field is generated by applying a contained, electrical current to the air in a room. While this current is completely harmless to human beings, it is extremely deadly to microorganisms, and essentially causes the chemical bonds that hold their bodies together to break down.
