Why should I be concerned about indoor air quality in the work place?

Indoor air is dirtier and more polluted than outdoor air. Health issues such as cancer, headaches, respiratory problems and fatigue can be caused by indoor air contaminants. These risks greatly increase in industrial settings where significant amounts of dust, fumes, exhausts are a part of the work environment.

Won’t an open window give enough ventilation?


In an industrial setting, the dust, fumes and exhaust generated in fields such as welding, vehicle production and woodworking pose such great health risks that merely opening a door/window is not a sufficient removal system.

Not to mention leaving a window or door open wastes money and energy on cooling/heating systems.

What is a micron?

A micron is a micrometer- a measurement unit equivalent to one millionth of a meter. A human hair is about 100 microns wide whereas dust particles and red blood cells are about 7 microns in diameter.

What are particulates?

In relation to air quality, particulates refer to tiny particles suspended in the air. As a general rule, the smaller the particle, the longer it stays in the air. Inhalation of particulate matter has been linked to asthma, lung cancer, cardiovascular problems and early death.

What is source capture?

Source capture systems are used when a process (such as welding / running a vehicle indoors / soldering) releases particulate matter (dust / exhaust / mist) into the air. An arm, hose or back-draft is attached or placed near the source to collect the particulate matter immediately. The air is then filtered and clean air is cycled back into the room or is discharged to the outside through a ducted system.

What is an air filter?

A device that removes particulates from the air.

What is HEPA filter?

A High-Efficiency Particulate Air (HEPA) filter removes a minimum of 99.97% of air particles 0.3 microns in size.

How are air filters rated?

The American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) has established international standards for air filters.

What is the difference between ASHRAE 52.1 and 52.2?

Standard 52.1 (1992): Describes an air filter in terms of a general efficiency percentage.
Standard 52.2 (1999): Assigns MERV rating.


What is a MERV rating?

The Minimum Efficiency Reporting Value (MERV) Rating is based on the efficiency of an air filter to remove particle of various sizes at different airflow rates.


What is the difference between a cartridge and a cyclone dust collector?

Cartridge dust collectors have perforated metal cartridges with pleated filtering media to increase the surface area, increasing the filtering capability and reducing the overall collector size.
Cyclone dust collectors use a cyclonic action to separate dust particles from the air.

What is a down draft table?

A workstation with built-in ventilation that sucks particulates into a filtering system before dispersing into the air.
