Testing High School Air Quality with the Dylos Air Quality Monitor Laser Particle Counter

Testing the air for 10 minutes during a class change at a Houston High School.
Dylos DC1100 Air Quality Monitor	Dylos Air Quality Monitor Laser Particle Counter measured the air particles in the hallway during 5 minute class change.
	5 Minute Class Change This Houston High Schools has 3000+ students in the hallway during class change. More than 500 kids passed me during this 10 minute test. Readings taken a 4 feet
Class Change 5 minutes	Lung Damaging Dust Particles reaching the Lungs Alveoli. >0.5 micron size particle count during the class change. Started at about 100,000 particles / ft3. In 8 minutes it was 3 times worse 300,000 particles / ft3. It's typical 100,000 particles / ft3.
Class Change 5 minutes	Dust, Pollen, & Molds Particles >5.0 micron size particle count during the class change. Started at about 2,000 particles / ft3. In 8 minutes it was 10 times worse 18,600 particles / ft3. A typical high pollen count day outdoors in Houston TX is 2,000 particles / ft3.
	Sneezes are capable of spreading respiratory disease through the potentially infectious aerosol droplets that they can expel, which generally range from 0.5 to 5.0 microns in diameter. A single Sneeze can send 40,000 tiny droplet particles speeding out of your nose at up to 100 miles per hour!
	Cough and sneeze in your elbow or on your sleeve.
