Wash and dry, in a washing bag, in the machine and/or dry heat treat before each use. (1 day =1 use) A combination of these two types of disinfection is also possible (e.g. 1 machine wash every 5 dry heats)

Machine wash: (in a wash bag)

Gentle cycle, water temperature ≥50-71°C (hot). Minimum 30 minute cycle. Regular detergent. NO fabric softener, bleach or additives. Place in a mesh washing bag to increase durability. To dry: tumble dry on high

Dry heat treatment:

Preheat the oven to 93°C (200°F); When the temperature is reached and checked, place the mask(s) on a rack or parchment paper and wait 30 minutes. Let cool for 5 minutes. Pay attention to the proximity to the heating elements. Store in a dry, clean place, not exposed to heat or sunlight above 100° C (212° F).
