Indoor Air Treatment

Indoor air quality (IAQ) directly affects the health and productivity of building occupants, making it one the most critical aspects of indoor environments.

While some contaminants appear as “particles,” such as dust, that can be captured by conventional filters, others appear as free-floating molecules, far too small to be filtered. For this reason, air replacement has been the only way to offset the buildup of these “molecular” contaminants. This is particularly true of CO2, by far the most abundant indoor-generated molecular contaminant, though equally relevant are volatile organic compounds (VOCs). Read more about research results showing the detrimental effects of increased CO2 levels on our brains. Indoor air treatment is one of four integrated capabilities in enVerid’s HLR® (HVAC Load Reduction) module. enVerid’s game-changing approach is based on molecular cleaning of indoor air. In its “adsorption” mode of operation, the HLR® system utilizes a combination of novel, efficient adsorbents to capture molecular contaminants and clean the inside air. Simultaneously reducing the amount of outside air being brought into buildings reduces the load on the HVAC system to heat or cool the air. The result: significant energy savings.

Cleaning Indoor Air

The HLR® system is the only commercially available solution that effectively captures CO2, VOCs and formaldehyde from indoor air in buildings. During the adsorption phase of the HLR’s operating cycle, a small portion of indoor air flows through the sorbents and contaminants are captured, allowing clean air to flow back into the building. CO2 levels are maintained near or below their target parts-per-million (ppm) levels, which can be set by users, even with high occupancy densities. VOCs and formaldehyde levels are also maintained at or below target levels. The intelligent feedback mechanisms designed into enVerid’s HLR control algorithms allow the system to keep up with dynamically changing levels of indoor contaminants, maintaining consistent and controlled indoor air quality.
