What is an Indoor Air Monitor?

Malcolm Tatum

An indoor air monitor is a device that is designed to constantly assess the quality of air found within an enclosed structure. Monitors of this type are routinely used in many different types of manufacturing and research facilities and are considered important in protecting the health of individuals employed within these facilities. This process of constant air monitoring makes it possible for the business to remain in compliance with standards set by the government agency that oversees conditions in the workplace. The presence of the indoor air monitor also allows the company to take immediate action in the event that devices used to purify the air begin to decrease in efficiency.


There are a number of different indoor air monitor solutions open to different types of businesses. Some monitors are stand-alone equipment that operate independently of heating, ventilation and air conditioning or HVAC systems. This means that even if an issue arises that interferes with the operation of the indoor air conditioning and heating system, the indoor air monitor will continue to function. There are also monitors that are included in the overall framework of air conditioning systems, some structured to operate on some type of backup power supply in the event that the main system should fail for any reason.

The main purpose of any indoor air monitor is to make sure the quality of air within the space is within acceptable environmental standards. This is particularly important when employees work with chemicals or other products that may emit fumes or release contaminants into the air. Depending on the nature of the business operation, the monitor can be configured to provide immediate notification in the event that indoor air pollution reaches certain levels that are considered unsafe. At that point, steps can be taken to evacuate the area and begin the process of cleaning the air and reducing the amount of pollution within the space.

While an indoor air monitor is typically found in modern manufacturing facilities, an increasing number of office spaces are making use of these devices to monitor indoor air quality. Along with helping to minimize airborne contaminants that increase the chances of colds and other ailments that adversely affect the productivity of employees, the monitors also play a role in preventing extended exposure to unsafe levels of contaminants. This in turn increases the chances that employees will not develop permanent health issues as a result of working for the company, and will not require some type of disability support in their later years.
