You will probably see items that are labeled "True" HEPA if you shop for HEPA air purifiers. So, I'm sure you're wondering, does that mean there's a false one? Of course you would never find a product that boldly proclaimed to be a sub-standard HEPA air purifier, but to be called a True HEPA air purifier, there are some differences. As with any other purchase, it's left to the consumer to figure out the differences and know if they need to look for one or the other. Let's examine True HEPA air purifiers and why some products may not claim this.
True HEPA Air Purifiers Are Different
A True HEPA air purifier, also known as an absolute HEPA air purifier, is different even from other HEPA air purifiers. When companies reference the effectiveness of HEPA air purifiers as stated by government entities such as the EPA and OSHA, they are generally referring to the True type, even if they do not blatantly say so. Although there are other types of air purifiers out there, True HEPA air purifiers are the only ones that are used in sensitive areas such as hospitals and laboratories.
True HEPA Air Purifiers Stop Particles Of DOOM
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.
True HEPA Air Purifiers 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.
Is There A Way To Tell If A HEPA Air Purifier Is True?
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. - 30286
