AIR QUALITY

INDOOR AIR QUALITY

PARTICLES in the air are a common form of pollutant. Approximately 2.4 billion particles can be found in a cubic foot, and of those 99% are smaller than 1.0 macrons.

HARMFUL EFFECTS of particulate matter (PM) can include damage to the cardiovascular system and can result in heart attacks and strokes.

INCREASE AIR QUALITY by developing an optimum filter plan. Air filters will remove harmful particulates and other contaminants from the air. When choosing the proper air filter, it is important to consider the following:

AIR QUALITY INDEX

ANSI/ASHRAE Standards 62.1 and 62.2 are the recognized standards for ventilation system design and acceptable indoor air quality (IAQ). Expanded and revised for 2022, both standards specify minimum ventilation rates and other measures in order to minimize adverse health effects for occupants.

STANDARD 62.1 specifies minimum ventilation rates and other measures intended to provide indoor air quality (IAQ) that’s acceptable to human occupants and that minimizes adverse health effects. The standard provides procedures and methods for meeting minimum ventilation and IAQ requirements to engineers, design professionals, owners, and jurisdictional authorities where model codes have been adopted.
