Sorbent air cleaning: A new way to think about ventilation

This webinar is available online


In commercial HVAC systems, one of the biggest challenges is managing the amount of volatile organic compounds (VOCs) in the air. A common solution is to use a large amount of outdoor air for ventilation—a method that uses a lot of energy in order to heat and cool the outdoor air. Sorbent air cleaning is an emerging technology that filters VOCs directly from the indoor air, making it a promising way to achieve indoor air quality while saving energy. 

In this webinar, Slipstream engineer Drew Morrison provides an overview of how sorbent air cleaners operate and how they are integrated into HVAC systems. Using real-world data from a 2019 field study of an sorbent air cleaning retrofit, we identify the building types where adsorbent air cleaners can be most beneficial and list several design and operational factors which make a building suitable for the technology. 

As a result of this webinar you will be able to:

  1. List the contaminants of concern that are addressed by sorbent air cleaners
  2. Explain the physical mechanism of sorbent filtration and the operational cycle of sorbent filters
  3. Explain how adsorbent air cleaning devices are installed in HVAC systems
  4. Quantify the net energy savings achieved by sorbent air cleaning systems
  5. List building design and operational features which make a building suitable for sorbent air cleaning
