1st Visit Fair Indoor Air Quality

2nd Visit Good Air Quality with a Desktop HEPA Air Cleaner

Ozone Alert Outdoors --Fair Inside Air Quality at the Desk!

The LIBRARY Indoor Air Quality is affected by the outdoor air quality.

The Librarian at Houston Graduate School of Theology can breathe easier with a HEPA Air Cleaner. The Indoor Air Quality was affected by 1 Million Vehicles and Trucks on Hwy 290 & 610 Loop / week and Train Idling on Hempstead Hwy. Fewer Particles were inhaled (> 50%) and fewer particles stayed in the lungs (> 50%). The Librarian breathed better through the work day and had more energy at the end of the day.

Emissions from cars and trucks are responsible for half of all the air pollution in Houston TX | www.drivecleanacrosstexas.org

610 Loop, Hwy 290, and IH-10 have 242,000 Cars and Trucks per Day (1.25 Million/Week) Traffic Intersection

The HGST School is surrounded by freeways that see > 1 million cars / trucks per week.

The southern winds blow the Diesel Fumes in the direction of the school from IH-10 and Loop 610.

Train Idling - The southern wind blows the Train's Diesel Fumes (Hempstead Hwy) in the direction of the Houston Graduate School of Theology.

HOW MANY PARTICLES THAT ARE INHALED STAY IN THE LUNGS?

ADULT SITTING IN AN OFFICE / LIBRARY

Adult BREATH 8.5 Liters/Min = (0.3 FT3/MIN)

INDOOR AIR QUALITY 40,000 Particles Count / FT3 @ >0.5 Microns

2,160 Particles Remaining in the Lungs and Blood Stream every minute. or

(1 million particles / 8 Hours Work Day)
