Causes of IAQ Problems

Reduced Reduced VentilationVentilation

InadequateInadequate

MaintenanceMaintenance

Since the energy crisis of the 70’s,

buildings are built tighter ... have

less ventilation...

and common pollutants are

trapped inside.

Why is IAQ a Problem?

EPA STUDIES SHOW THAT INDOOR POLLUTANTS ARE 10 –100 TIMES GREATER THAN OUTDOOR

Why is IAQ a Problem?

AMERICANS SPEND 80% - 90% OF THEIR TIME INDOORS

COST OF EMPLOYEE ABSENTEEISM IS ESTIMATED BETWEEN $6 - $9 BILLION EACH YEAR

How to Reduce VOCs

IF WE CAN’T REMOVE THE SOURCE WE NEED TO MODIFY

THE SOURCE

Increase VentilationClean Vents for good

air flow

DUST

What is Dust?

ash, soot, dirt cotton, paper, fibers asbestos, fiberglass paint, metal, mineral plaster, chalk dander, pollen, spores

Anything small enough to float in air.

Size of Airborne Dust

Very small (1 - 100 microns)

1/100,000 to 1/10,000 inch

Cannot be seen by

“naked eye”

WALKS

door

Over 85% of Building Dust

To Reduce Dust

Walk off Mats Filters, filters, filters... Treated Dust Cloths Dust Mopping Always dust mop after

buffing Dust air vents Effective Vacuuming with good vacuum
