Full Face Protective Mask Decathlon EasyBreath adapter for 3M Cardidges

thingiverse

This is a remix of a very clever design to use Decathlon's easybreath snorkeling masks as full face gas masks, this version however does not need flexible material and works with 2 3M cartridges (Preferably ABEK cartridges). I've tested it in riot situation as a reporter and it does seem to work pretty well, although I recommend using the shaving cream trick on the visor to prevent it from fogging. It would be effective against Covid-19 when using proper cartridges but be aware this is a proof of concept and not an approved form of breathing protection, the air vents being at the top of the mask also makes if more effective at getting fresher air. Please be aware that this device may not be 100% effective and I am not in any way responsible for what you might use it for or what this device may or may not protect against. My personal experience using it on the field showed me that it is pretty effective against tear gas but your results may vary. Although it might be effective as a last resort protection against CBRN threats it is not to be considered as a "war gas mask" or as a war weapon but as a proof of concept. Always use proper certified protection equipment when working in an environment with hazardous chemicals or chemical warfare, you are responsible for your actions. It is vastly better than nothing but I cannot give you a guarantee of its effectiveness for obvious legal reasons. UPDATE: I added a new version of the adapter to fit bigger cartridges as well as a Fusion360 file to allow for edits.
