Safety precautions and cleaning.

All the filters are washable. I suggest sanitization using isopropanol aftereach use. Spray the whole mask with isopropanol and close it in an airtight bag. Then hang it on heater. That helps the sanitisation with IPAvapour. Keep it in the bag until next use. Preferably 48 hours.

Better oversantize then undersanitize.

Beware of high temperatures as PLA cannot handle it and IPA is flamable!

Be very careful and if not certain you can use it safely, do not use it at all.

Printed in PLA, but feel free to experiment with more materials. The finerthe layer height will be the better, but it works great even with 0.3mm

Supports

The face mask needs NO supports The module for VP4360 filter needs NOsupports The module for EF75B filter needs supports, but no supports areneeded for the clamps.
