True HEPA Air Purifers Are Better

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.

Do True HEPA Air Purifiers Stop Particles That Others Don't?

70 to 100 microns of thickness is the typical human hair. Consider how small 0.3 micron particles must be, then consider that although they must be tiny the true HEPA air purifier must be able to filter out at least 97 percent of particles that size to qualify. Although this may sound very technical, keep in mind it is actually a very important consideration. Particles of this size are the hardest to filter, even the smaller ones are easier to filter out. 0.3 microns are small enough in size to bypass the human body's defenses to get into the respiratory system and cause many illnesses. Thus, it is important that the true HEPA air purifiers be able to filter these tiny particles.

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.

Is There A Way To Tell If A HEPA Air Purifier Is True?

The packaging will give you all the information you really need to know if it is a true HEPA air purifier. Beware of the many HEPA-type air purifiers that are on the market that are held no to actual standards of filtration. If the product does not advertise as either "true HEPA" or "absolute HEPA" then check for the efficiency ratings on the packaging. Remember, you are looking for it to filter at least 97 percent of those tiny, dangerous 0.3 microns and if it doesn't then it is not a true HEPA air purifier.
