Clean Air Everywhere You Stay — RZ AIRFlow for PTAC Heating & Cooling Units The RZ AIRFlow is an internationally patent-pending air purifying system engineered specifically for PTAC (Packaged Terminal Air Conditioner) units — the wall-mounted heating and cooling systems found in hotels, senior living facilities, apartments, and extended-stay properties. Where standard PTAC units recirculate unfiltered air, the RZ AIRFlow installs directly into the unit and delivers True HEPA 99.97% filtration of airborne particulates down to 0.3 microns, combined with an active carbon layer that eliminates organic smells and odors and VOCs. Built by RZ Mask — The company behind 3+ million respiratory protection products sold worldwide since 2010 — The RZ AIRFlow applies the same filtration engineering that defines the RZ Mask lineup to the spaces where people sleep, recover, and live.
