enVerid’s HLR technology is the only solution that removes carbon dioxide (CO2), aldehydes, volatile organic compounds (VOCs) and particulate matter (PM2.5) from indoor air.

The enVerid HVAC Load Reduction (HLR) Modules is an air scrubbing solution that contains regenerative sorbent cartridges, along with embedded web-accessible controls and sensors. Individual or multiple HLR modules can be used depending on the building size. The HLR modules can be retrofitted into an existing HVAC infrastructure or installed in new construction or renovation.

The enVerid Air Purifier is an in-room, ceiling mounted True HEPA air cleaner with optional UVC lamps that captures 99.99% of viruses including a surrogate for the COVID-19 virus. Suitable for offices, classrooms, retail stores, and other commercial applications looking for a long-term, commercial-grade local HEPA solution, the product delivers a low cost, easy to install, ultra-quiet, and energy efficient alternative to costly HVAC system upgrades. Units can be mounted below the ceiling where their visibility provides peace of mind, or out of sight in the ceiling plenum. Each unit comes with a wall-mounted LCD display controller for easy monitoring and control.

Brand Details

enVerid’s mission is to make the world a cleaner, healthier place – both inside and out. We do this by developing products that deliver cost savings and healthier indoor air quality (IAQ) for the built environment. This endeavour has been internationally recognized as follows:

  • ASHRAE product of the year 2019, 1st Place AHR Green Building category 2019
  • ASHRAE Product of the Year 2018

ASHRAE Standard Compliance:

62.1: The HLR 14M & 15R Modules are compliant with ASHRAE 62.1 Indoor Air Quality Procedure (IAQP), the preferred approach to achieve energy efficiency and indoor air quality (IAQ). Introduced in 1981, IAQP is a performance-based design procedure that determines outdoor air intake rates based on an analysis of contaminant sources and air cleaning capacity to stay below recommended contaminant concentration limits. The ASHRAE 62.1 Standard recognizes that “The IAQP may allow for a more cost-effective solution to providing good air quality.” Additionally, “The IAQP may also be used to achieve better air quality than VRP.”

145.2: The cleaning efficiency for HLR modules was tested by a third-party lab in accordance with ASHRAE Standard 145.2 – Laboratory Test Method for Assessing the Performance of Air-Cleaning Systems.
