Commercial Indoor Air Quality

According to the EPA, poor indoor air quality (IAQ) is among the top five environmental risks. Pollutants in your building’s air can cause dizziness and headaches, and can aggravate allergies and asthma.

Regular cleaning and vacuuming can go a long way toward improving the air you breathe. But cleaning alone will not solve IAQ problems.

Four key strategies to improve air quality, comfort and productivity:


To help keep track of relative humidity and carbon dioxide, sensors measure these levels and can be acted upon by by a facility manager or HVAC system.


By taking steps to remove harmful elements circulating in your building, you minimize the build-up of pollutants to enhance comfort, efficiency and air quality. Lennox’ dehumidification systems are part of an effective strategy to maintain a proper balance of temperature, humidity and airflow.


Ventilation is essential to improving indoor air quality by cost-effectively incorporating fresh air that reduces the concentration of chemicals, carbon dioxide and other contaminates. Ideal for tightly sealed buildings, a ventilation system helps replace stale, contaminated indoor air with fresher outside air.


Pollen, dust mites, dirt, bacteria and molds are just a few of the contaminants that can adversely affect air quality. Filters provide a valuable barrier to eliminate the circulation of these harmful elements.
