HEPA air filters - Get Serious About Air Quality!

There are other mechanical filters on the market, but an HEPA air filter outperforms them all – with the exception of Hyper HEPA and Ultra HEPA air filters, but as their name suggests, they are based on the same technology.

One thing to be aware though off, is that a HEPA-type air filter is not a True HEPA air filter – it’s efficiency is often only 55% of that of the real McCoy.

A HEPA air filter is made of sub-micronic glass fibers in a thickness and texture very similar to blotter paper, and is guaranteed to filter out any particles of 0.3 micron and larger.

Have a look at this list detailing the sizes in micron of household pollutants:

• Viruses 0.003 - 0.05
• Tobacco smoke 0.01 - 1
• Cooking smoke 0.02 - 1
• Combustion gases 0.02 - 1
• Bacteria 0.35 - 10 (99% of bacteria are larger than 1 micron)
• Skin flakes 0.4 - 10
• Pet dander 0.5 - 100
• Dust mite debris 0.5 - 50
• Household dust 0.5 - 100
• Mold 2 - 20
• Coal dust 2 - 100
• Pollen 5 - 100
• Plant spores 6 - 100
• Lint 10 - 100
• Human hair 70 - 100

As you can see, the only things on this list that are not trapped by HEPA air filters are smoke and viruses.

However, what you have to take into account is that 90% of airborne particles are smaller than 0.3 micron. These are known as “lung penetrating particles”, and are the ones most dangerous to your health.

However , the good news is that HEPA air filters actually are capable of filtering particulates smaller than 0.3 micron, even as small as 0.01 micron, but the percentage that is actually filtered drops of quickly at that size.
