It's not a medical device, but better then other home made masks. !!</p> <h3>Assembly</h3> <p>Glue all the parts together for the best results.</p> <h3>Safety precautions and cleaning.</h3> <p>All the filters are washable. I suggest sanitization using isopropanol after each use. Spray the whole mask with isopropanol and close it in an air tight bag. Then hang it on heater. That helps the sanitisation with IPA vapour.<br/> Keep it in the bag until next use. Preferably 48 hours.</p> <p>Hooks available here: <a href="https://www.prusaprinters.org/prints/26029-symmetric-rail-panel-heater-hook-hanger">https://www.prusaprinters.org/prints/26029-symmetric-rail-panel-heater-hook-hanger</a></p> <p>Better oversantize then undersanitize.</p> <p>Beware of high temperatures as PLA cannot handle it and IPA is flamable!</p> <p>Be very careful and if not certain you can use it safely, do not use it at all.</p> <h3>Print instructions</h3><p>Printed in PLA, but feel free to experiment with more materials.<br/> The finer the layer height will be the better, but it works great even with 0.3mm</p> <h3>Supports</h3> <p>The face mask needs NO supports<br/> The module for VP4360 filter needs NO supports<br/> The module for EF75B filter needs supports, but no supports are needed for the clamps.</p> <h3>Assembly</h3> <p>Glue all the parts together for the best results.</p>
