The clear path to healthier air

This question (related to airborne transmission) is too difficult to answer without knowing all of the the associated environmental variables. There is actually an equation for this, called the Wells-Riley equation. The main variable is airflow dynamics.

The secondary variables to the risk of infection are the particle sizes expelled, the viral load (contagion), inhalation, and time. The best answer I can give is that the optimal protection from anyone in a room that has a viral load from COVID-19 is our Air Guardian solution. That has to do with VENTILATION (airflow) and the extent to which we purify that airflow. Clean air is 100% processed by our fixture and dropped into safe zones that reside within the strata of air that is being inhaled.

In an airborne infection, how that particle is carried through the air, how fast, and at what level must be considered as the primary variables and hazards to infection. You can read all about this in our white paper.

The Air Guardian solution actually makes rooms with less air “circulation” safer for the above reason. We mechanically induce ventilation and mix clean air into the rooms with high-volume room air changes.

Within the Air Guardian, air first passes through a ceramic mesh of titanium dioxide embedded with TiO2 nanoparticles, which are rutile-state reflective crystals. They are highly reactive to ultraviolet light. The ceramic mesh used is irradiated by powerful UVA 365 light, thereby forming a cloud of highly reactive electrons and subsequent ROS. The UVA light irradiance itself is also destructive, so dual toxicity begins immediately within the Air Guardian. Intense 265 nm UVC light (30 joules) bathes the air for up to 36 seconds. This mechanism, along with The ROS inactivate microorganisms, including viral pathogens. The ROS oxidation process produces no noxious compounds.
