Information On HEPA Air Purifiers And What They Can Do For Your Pad And Household

By Angela Frazie

The term HEPA seems to be everywhere nowadays. There are HEPA filter air purifiers, HEPA filter vacuum cleaners, HEPA air conditioner filters, the list goes on and on. But what, exactly, is HEPA, what does it mean, and how does it work? Let's examine the mighty HEPA air purifier, as well as other applications, to get a better understanding of this often used term.

Why is HEPA Capitalized?

Since HEPA is an acronym, it's written in all capital letters. Spelled out, HEPA means "high efficiency particulate absorbing". Some maintain that it really means "high efficiency particulate arrestance", which is probably more accurate. Explained in plain English, HEPA air purifiers absorb, or at least put a stop to particulate matter, which are tiny, fine particles of stuff in the air that the human eye usually can't see.

How Do HEPA Air Purifiers Help People?

Although HEPA air purifiers do clean pollen and dust out of the air, there are many more particles that are not natural to our environment, and that our human respiratory systems do not deal well with. Sometimes we can detect these other particles in the form of allergens and odors, sometimes we can't. Unfortunately, there are many pollutants that our bodies simply don't recognize and don't defend against, which leaves them to damage our lungs and other inner parts. Having a device that can either stop or absorb these dangerous particulates can definitely have a positive impact on one's health.

What Can HEPA Air Purifiers Do That Others Cannot?

Not all air purifiers are equal. Most entities that test any type of air purification device compare the results to "HEPA standards". This is because, for nearly half a century, this type of air filtration has been the absolute king. What makes the HEPA filter air purifiers so great, though, is their ability to stop particles 0.3 micrometers in diameter. This is not a random number or designation. It has been found that, when it comes to the human body, 0.3 micron particles are not only the most dangerous, but also among the hardest to filter.

Is There Really A Difference Between HEPA-Type And HEPA Air Purifiers?

A true HEPA air purifier is held to certain standards. Chief among these standards is the ability to filter at least 99.7% of all 0.3 micron particles that pass through the machine. This is an extremely lofty standard, and you can expect to pay a premium for this ability. Generally speaking, HEPA air purifiers are not cheap. A HEPA-type air purifier, however, is a completely different animal. It's important to realize that there is absolutely no standard whatsoever that a HEPA-type air purifier must pass. A machine with this designation could be anything from a less effective, less expensive alternative to a completely useless piece of junk. Also, be wary of putting too much trust in HEPA air purifier reviews. The best HEPA air purifier will not only produce clean smelling air, but it will also remove particulates that are not detectable with human senses alone. - 31822
