micron is really, really small. The width of a human hair is about 70
microns. Our eyes can see no smaller than 40 microns, and you’ll need
a decent microscope to see a particle 20 microns wide. Allergens like
dust, smoke and bacteria are particulates that are often .3 microns or
less. At that size, they can get deep into your lungs, because they
aren’t filtered well by your nose and throat.
you’re concerned about controlling those airborne particulates, it’s
good for you to know that Trane
CleanEffects™ removes 99.98% of particulates, all
particulates, from the air inside your home.
