True HEPA Air Purifers Are Much Better

0 Comments | Rating: 0 | |

Items advertised as "True" HEPA air purifiers are often available when one is shopping about for a HEPA air purifier. Considering something is being labeled as true must mean there as some out there that are false, correct? You will not find any labeled "sub-standard", "false" or any other such derogatory adjective. True HEPA air purifiers are simply comparing themselves to other systems and then leaving it up to the consumer to know what they need and how it will affect them. This article looks at what comparisons the "True" HEPA air purifiers are making.

Differences! True HEPA Air Purifiers Have Them

Even though they are HEPA air purifiers, if they do not say "True" or possible "Absolute" HEPA air purifier, they are not the same thing. When HEPA air purifiers are advertising effectiveness as stated by such government agencies as the EPA and OSHA, they are generally the true type even if not specifically stated on the packaging. Regardless of the other air purifiers on the market, institutions such as hospitals and laboratories are such sensitive areas that they only use true HEPA air purifiers.

Particles! True HEPA Air Purifiers Stop Them

Of the different specifications that True HEPA air purifiers have to meet, the most important is probably the 97% of all 0.3 micron particles. This stat is incredibly important, and not as technical as it may sound. Of all the different pollutants floating around out there, it's been found that 0.3 micron particles generally are the hardest to filter, even including those that are smaller. They also are the most likely to cause problems in the human body, and have no problem scooting right past our natural defenses. See, 0.3 micron particles are more scary than nerdy, aren't they? If you want an idea of the size we're talking about, compare 0.3 microns to the human hair. Human hair is generally anywhere between 70 and 100 microns thick.

Best When Dirty! True HEPA Air Purifies Actually Work Better When Dirty

This part of our discussion is where you will see both the main difference between true HEPA air purifiers and others and also where the terms "Absolute" and "True" become one and the same. Designed to be more effective dirty than when clean, the absolute filtration system's trapped particles will actually increase the power of the true HEPA air purifier's filtration. Very simple in reality, the explanation is that the spaces for the the air to pass becomes smaller as the dirt builds up.

How Do I Know If It's A True HEPA Air Purifier?

Look for products that actually advertise that they are True HEPA air purifiers. The alternative is the HEPA-type air purifier, which is really just an imitation, and is not held to any particular standard. If you find a purifier that doesn't say either HEPA-type or True HEPA, you can also reference other specifications on the box. Look for one that filters 97% or more of the 0.3 micron particles if you want a True HEPA air purifier.
