Why the aerosol-reducing mask?

The Aerosol-Reducing Non-Invasive Ventilation Mask is intended to be worn by hospital patients in respiratory distress. It has a universal 3D printed adapter that allows it to be attached to any existing commercial BiPAP or CPAP machine.

The device functions similar to existing masks, but has the advantage of significantly reducing aerosolization – the process by which virus droplets are emitted into the air. Healthcare workers have long been at risk of virus exposure with BiPAP and CPAP patients, a risk that has been compounded by the ongoing COVID-19 pandemic.

Using off-the-shelf devices and 3D printing technology, our Aerosol-Reducing Mask is poised to transform the standard of respiratory care by nearly eliminating risk of aerosolization.

Traditional masks for BiPAP and CPAP machines leak air at high pressures; as that air can contain virus particles, it can cause infection of anyone within the vicinity of that patient. To address this problem, we’ve combined readily available facepieces that have a double seal – one around the mouth and nose, and another around the face – with open source 3D printed adapters to create a high quality device that leaks less air. The Aerosol-Reducing Mask is produced by Glia as a Health Canada-approved Class II medical device.

The Aerosol-reducing Mask can be used any time infection control is a concern, including with patients who may be at risk of an aerosol-borne disease such as COVID-19, influenza, or other viruses.

The Aerosol-Reducing Mask has been extensively tested and is ready for use in emergency rooms, intensive care units, pre-hospital transport, intra- and inter-hospital transport, and for emergency use in remote health stations without access to assisted ventilation systems. It comes in multiple sizes to ensure proper fit, and includes a large visor for patient comfort and visibility.
