EnviroKlenz conducted case studies with educational partners at various locations in the United States during the COVID-19 pandemic.  EnviroKlenz Air System Plus was deployed and operational alongside an air meter that measures and records particulate matter. The EnviroKlenz Air System utilizes multi-stages of filtration consisting of patented technology for a broad array of contaminates, UVC (254 nm wavelength), and HEPA.  The air meter provides real-time estimates of particulate matter concentrations (PM1, PM2.5, PM10) and particle size distribution using a combination of multiple light scattering-based particle sensors.

The systems ran in operational educational environments with daily schedules being carried out as usual.

Increases and decreases in the particulate matter were observed as expected given the conditions with the air monitor.

The results from the case studies with the EnviroKlenz Air System Plus were compared to particulate matter data from the Environmental Protection Agency (EPA).  From 2000-2019, the EPA, through a nationwide network of over 400 monitoring sites, developed ambient air quality trends for PM 2.5 particle pollution, representing fine inhalable particles, with diameters that are generally 2.5 micrometers and smaller.  In the EnviroKlenz case studies, a broader range of particles was monitored, all with similar trends, but for illustration purposes, the data collected aligned to the size range of the EPA data is shown by plotting the national standard and the top 10 percentile for air quality for comparison.
