Better indoor air quality and up to 40% HVAC energy savings for commercial buildings

Each HVAC Load Reduction® module provides cleaning capacity for 15,000-25,000 ft2 of space. One or more HLR modules can be used to scale to any building size or system type.
Discover HLR Technology

We make the world a cleaner, healthier place – both inside and out.

Reduce HVAC equipment costs

HLR modules clean the air in buildings so that indoor air can be safely recirculated. This allows outside air requirements to be reduced by up to 85% using ASHRAE’s Indoor Air Quality Procedure (IAQP). The reduction of required outside air decreases project first costs by allowing for HVAC system downsizing. 

Reduce building operating costs

Lowering outside air requirements using HLR technology and ASHRAE’s Indoor Air Quality Procedure (IAQP) reduces the load on HVAC systems, which in turn saves energy, reduces carbon emissions, and extends equipment life. This is because less outside air needs to be heated in the winter and cooled in the summer before it is circulated throughout a building. Lower outside air requirements also make it easier and less expensive to control humidityDeploying HLR modules with ASHRAE’s IAQP can deliver up to 40% HVAC energy savings.

Improve occupant health and productivity

HLR modules improve indoor air quality, removing contaminants generated by building materials, furniture, and cleaning agents, and by reducing the intake of outside air that is often polluted with exhaust from highways and airports, smoke from industrial parks and wildfires, pollen, and ozone, which is a known carcinogen.

Reduce building carbon footprint

Reducing load on HVAC systems by cleaning the air in buildings so that it can be safely recirculated and outside air requirements can be reduced significantly lowers the carbon footprint of buildings by making the HVAC system more energy efficient. Buildings account for approximately 40% of global carbon emissions, and heating and cooling is the single largest energy consumer and contributor to their emissions. 

Healthy Buildings by Joseph G. Allen and John D. Macomber

Recommended by Healthy Buildings and IAQ Experts

Healthy Buildings by Joseph G. Allen, Director of the Healthy Buildings program at Harvard’s T.H. Chan School of Public Health and John D. Macomber of Harvard Business School has this to say about enVerid’s technology (pg. 227-228):

Then there are companies working on better ways to clean the air. …like enVerid, which can install a system within your existing ductwork to capture and purge VOCs, CO2, and other chemicals.”


“We chose to single out these particular companies because we’ve gotten to know them well. We’ve met with dozens of executives from different organizations, and there is a reason these companies show up in our book: we think they are doing it right, or are on the path to doing it right.”
