How Hepa Filters Work
You have more than likely heard that Hepa filters remove around 99.97 percent of all particles found in the air down to .3 microns. However, do you really understand how these filters accomplish such a task?
With a hepa filter in your vacuum you will not only be removing dirt that you can see but you will be sucking up all those tiny little germs, dust, and grime that you cannot see. How can a vacuum filter do so much?
Okay, here is the run down on why and how the hepa filters work:
Are created from tiny glass fibers
Then woven into a tight woven paper filter
This makes many small sieves
These sieves capture very small particles including biological agents
After these particles are trapped, they cannot flow back into the air because of the absorbent pores
