Peace of Mind for COVID-19 and Wildfire Smoke Mitigation
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. The enVerid Air Purifier can be used in conjunction with our HLR units or independently.
Independent Testing Validates Unit Efficacy
Third-party tests conducted by LMS Technologies, a US-based independent air media and filter testing company, showed that the enVerid Air Purifier removes 99.99% of viruses from air passing through the filter. Testing was done using MS-2-bacteriophage, a surrogate for SARS-CoV-2. Viral efficiency testing was performed according to ASTM F2101–19, the testing standard for medical face mask materials. Testing by LMS also showed a single pass efficiency of 99.99% for particles as small as 0.1μm, well below the size range attributed to bioaerosols that can carry viruses. The UVC sterilization lamp installed in the return air box kills bacteria and viruses adsorbed on the filters. The enVerid Air Purifier can also be used without the UVC sterilization lamp. The enVerid Air Purifier unit and the display panel are fully UL certified according to UL 507, UL 867, UL 900, and UL 60730-1.
A Better Solution for Cleaning Air in Schools
The enVerid Air Purifier offers schools a cost-effective, long-term solution to remove virus particles and wildfire smoke from indoor air without the significant expense of upgrading HVAC systems and the “energy penalty” associated with conditioning higher volumes of outside air. Unlike temporary portable air filters that are noisy and distracting, use valuable floor space, present trip hazards from electrical cords, and are difficult to track and manage because they are easy to unplug and move, the enVerid Air Purifier is a permanent, optimally placed solution that is quiet, easy to operate, and manage at scale.
How it Works
Each enVerid Air Purifier unit is mounted from the ceiling, quietly pulling air from the occupied space and running it through a pre-filter and True HEPA filter. Cleaned air is then sent back into the space. Each unit treats up to 1,000 ft2 of space, cleaning the entire air volume every 20 minutes. Multiple units can be installed to meet the requirements of any size space.
The diagram shows the components within the enVerid Air Purifier and the wall-mounted control panel. The control panel is connected to the unit using a hard-wired connection and can be mounted in the space or in a nearby IT or electrical/ mechanical room.
Installation and Maintenance
The enVerid Air Purifier’s slim profile and ducted design allows for easy installation and wide coverage area. It can be installed below the ceiling or in the ceiling plenum.
Four hanging brackets are included with the unit for installation with 3/8” threaded rods (not included). Duct connections and ceiling return may be required depending on the installation. The unit requires access to 120V power and is connected to the controller with an 18-gauge stranded shielded communication wire (not included). Side access is required for safe and easy filter replacement. The filter display on the control panel shows the number of days until the next HEPA filter replacement, which is required every six-months if the UVC lamps are in use and twelve months if they are not in use. The washable pre-filter should be cleaned every time the HEPA filter is changed and replaced every 1-2 years. The UVC lamp bulbs should be replaced every 9,000 hours and cleaned whenever the HEPA filter is replaced.
