DISCLAIMER
This product does not guarantee complete protection against COVID-19 as its efficacy is strongly dependent on the filter used.
It has been created aiming to reduce the usage of professional respirators by the public as they shall be reserved for medical operators.
Many 3D printed masks around the web claim to have a big intake area (filter slot) in order to reduce pressure drop on it and increase filter efficacy. This is true when talking about professional certified respirators. But be careful! Most of the homemade filter you are using cannot be considered fully effective against COVID-19.
A 3D printed respirator shall be thought more as a shield (assuming the filter will not be a professional one). Therefore the smaller the intake area the better (still assuring proper breath-ability). If proper filters would be so common and available, there would be no need of printing a mask.
