Here is the version V3 of my filter adapter for the Easybreath tribord with active ventilation. Suitable for filters ("Toom" hardware store) with Ø 80mm thread. To protect against, for example, the Corona Virus. I used a filter class A1B1E1K1 for protection against organic, inorganic and acidic gases and vapors, as well as against ammonia and organic derivatives. You should get similar filters from other Hardware Stores to. Hardware you need: of course the "Easybreath" 4 pcs. Screw M3 x 40mm length 4 pcs. Nut M3 Axial Fan - size 60x60x20 mm For the groove (Gas mask adapter active filtering V2 Bottom) you can use a Ø1.75mm elastomer (TPE, TPU ore TPS) filament as a seal.
