Inhalable dust is filtered in the nose, throat, and upper respiratory tract. Most of this dust is greater than 100 microns. This dust is removed through natural clearance mechanisms. |
|
Thoracic dust is filtered in the lungs and down to the gas exchange regions. Most of this dust is greater than 5 microns and can be removed through natural clearance mechanisms. |
|
Respirable dust refers to those dust particles that are small enough to penetrate the nose, upper respiratory system and to the gas exchange region (alveolar). Most of this dust is less than 4 microns. Particles that penetrate deep into the respiratory system are generally beyond the body's natural clearance mechanisms and are more likely to be retained. |

Your respiratory system acts as a gateway for carcinogens, pollen, dust and bacteria to infiltrate your body.
One micron is .000001 meters or about 0.000039 inches. The human hair is 100-500 micron. You can see down to about 30 microns. The dot at the end of this sentence is 600 microns.
Installers of the Perry Air Filter Systems have shown a technical understanding of how indoor air quality is an integral part of any HVAC system. They provide initial installation and can answer questions regarding future maintenance and filter media changes.
