Combining a full-face snorkel mask (Decathlon Subsea Easybreath) with a HME bacteria and virus filter used in anesthetic equipment and ventilators, the COVID Lifesaver Mask is an ingenious solution to the shortage of personal protection and face masks in many countries with shortage. We hope it will also improve safety for medical staff in case certified personal protective equipment (PPE) is unavailable.





Test results

At this time our test results show some leakage, the level of protection of the mask currently can not be quantificated.







Both literature and our tests suggest that pleated, hydrophobic filters are superior to electrostatic HME filters. The HME filter combination does pass tests but only in N95 setting. It seems that the that pleated, hydrophobic filters are superior, to find more results and elaborate testing please visit https://www.pneumask.org/clinical-validation





Sharing the designs

As the severity of the Corona virus epidemic needs fast action, we were sharing the designs immediately on an open-source basis, so that the adapted mask could be quickly and easily replicated for use by medical staff around the world.

With superior filter alternative filters available we would suggest you would use the links to other interesting projects for their designs.





Our thingiverse link is currently unavailable untill we have a definate grade of the safety level. Before use a personal fit test would always be recommended. A solution to overcome the risk of inward leakage could be combining the mask with possitive air pressure.





If you have certified PPE available we strongly recommend you use this.





Testing is on-going

While development and testing is on-going, we welcome your feedback.
