Commercial Indoor Air Quality Services

Some of the most common types of Indoor Air Purification technologies include:

HEPA (High Efficiency Particular Air) Filters – These powerful filters are capable of 99.7% effectiveness in eliminating allergens and most types of bacteria but will not remove gases and fumes, including those produced by many industrial solvents and cleaners.

Ultraviolet Germicidal Irradiation (UVGI) Lamps – long used in laboratories and hospitals for their ability to kill disease causing micro-organisms, a UVGI light system can make a valuable contribution to increasing indoor air quality. The lights are typically placed within the HVAC system or ducts and so are not visible. While they do destroy a host of dangerous micro-organisms, UVGI systems do not actually remove particles or gases from the air and are less effective against mold and bacteria.

Ionizer Purifiers – these units use electricity to create charged ions which attach themselves to airborne pollutants which are then drawn into a charged collection plate that can be periodically cleaned. Ionizer Purifiers are available as portable units or can be permanently mounted (in which case they are called electrostatic precipitators).

Disadvantages include the production of trace amounts of ozone and, in some units, a popping noise from the electrostatic charge.

Humidifiers and Dehumidifiers – to achieve a healthy building it is essential to maintain the proper level of humidity – too much moisture in the air can lead to the growth of mold and harmful bacteria, too little allows particles to remain airborne and can lead to increased instances of illness. A trained IAQ professional can measure the level of humidity and make recommendations for the right system to regulate it.
