Peace of Mind for COVID-19 Mitigation
The enVerid Air Purifier is a ceiling mounted, high efficiency air filtration system with an ultraviolet germicidal irradiation (UVGI) sterilization lamp that has been shown to capture 99.99% of viruses including a surrogate for the COVID-19 virus. Suitable for offices, classrooms, retail stores, and other commercial applications, 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.
Independent Testing Validates Unit Efficacy
Third-party tests conducted by LMS Technologies, a U.S.-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 99.95% for particles whose diameter is equal to 0.3-0.5 μm, the lower end of the size range generally 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.
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 multi-stage series of high-performance filters. 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.
This 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.
The Air Purifier’s slim profile and ducted design allows for easy installation and wide coverage area. Installation is simple for both retrofits and new construction; it can be installed below the ceiling or in the ceiling plenum.
Four hanging brackets are included with the unit. Duct connections and ceiling return may be required depending on the installation. The unit requires access to 110V or 220V 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 high efficiency filter replacement, which is required every six months if the UVC lamps are in use and every twelve months if they are not in use. The washable pre-filter should be cleaned every time the high efficiency filter is changed and replaced every 1-2 years. The UVC lamp bulbs should be replaced every 9,000 hours and cleaned whenever the high efficiency filter is replaced.
