That’s right! The air inside a typical home is up to 5 times dirtier than the air outside! The same technology that makes our homes energy efficient, also keep in chemicals and particulates that we would be better off not having to take into our respiratory systems.

Everyone has a certain tolerance for airborne chemicals and particulates. Some people’s tolerance is very high. Other folks, such as those with allergies, the very young, the elderly and those with compromised or weakened immune systems are not so lucky and are more at risk if exposed to excessive airborne contaminates.

The key is to reduce the amount of contaminants taken into the body’s respiratory system. HEPA, which is an acronym for High Efficiency Particulate Absorbing, is an air filtration standard developed by the U.S. Atomic Energy Commission. HEPA air filtration is 99.97% effective at removing particulate 0.3 micrometers in diameter.

Without getting too technical, it is important to understand that 0.3 micrometers is not the smallest size HEPA filters will capture, but 0.3 is what is known as the MPPS or Most Penetrating Particle Size, and 99.97% of all particles exactly this size will be stopped by the HEPA filtration. Particles smaller or larger than 0.3 are trapped with even higher efficiency.
