How can schools and childcare spaces use NanoFlashing?

Can a classroom unit maintain useful airflow while remaining quiet enough for teaching?

A classroom unit is a finished product of the manufacturer that makes it, and its noise, its controls, its cable and its stability are that maker's. What airflow a unit moves, and how quiet it is, are set by that unit's design.

C-POLAR markets a materials technology. Every commercial NanoFlashing™ product is made by a manufacturing partner, in their facility, in their format. The manufacturer and seller of a finished product are responsible for its design, manufacture, labeling, instructions, claims, sale, and warranty, except for a responsibility C-POLAR expressly accepts in a Separate Agreement. INHALO™, named on the Air page, is a wall-mounted air cleaner built around a NanoFlashing™ Air Filter. It runs continuously at breathing height without occupying floor space.

C-POLAR publishes no noise or airflow figure for a classroom unit; a figure of that kind belongs to the maker of the unit. Passive describes the filter, not the system around it. The filter is passive. It draws no power, and it has no power supply, electrode, lamp or reservoir. NanoFlashing™ is a technology; the name, rating and sale of a product that carries it are set by that product's maker and seller.
