Indoor Environment Quality


Your Indoor Environment

 Office employees spend up to 90% of their time indoors with HVAC air conditioning, and can receive high exposure to contaminants through the confined, air-conditioned space.

Indoor air quality (IAQ) refers to the cleanliness of air within a building. Contaminated indoor air possesses a health risk to people, causing headaches, coughing and respiratory illness.

Internal air systems (HVAC) play an important role in your standard of IAQ. Unmaintained HVAC systems can endanger occupant health and become costly for business owners and managers. HVAC systems should be assessed and cleaned regularly to ensure cleanliness of air. Maintaining acceptable levels of HVAC hygiene reduces the risk of degraded air quality and ensures the supply of clean, healthy air.
