PRECIMASK® are cleanable and durable masks over time.

the cleaning protocol is broken down into several types :

Type 1 for daily disinfection of the mask
Type 2 for the simple regeneration of the filter cartridges once a month
Type 3 for enhanced regeneration of the filter cartridges in case of clogging (cannot be regenerated with boiling water)

Regenerations (Type 2 & 3) allow the ceramic to be thoroughly cleaned.

Cleaning protocols

Daily disinfection

of PRECIMASK®

Type1

CLEANING

This cleaning is recommended after a day of wearing the mask to ensure viral inactivation and to properly dry the cartridges, especially if used in a humid environment. Place the filter cartridges in your oven at 90°C (200°F) for 10 minutes. The rest of the mask should be washed with hot soapy water, or with a virucidal cleaning solution.

If you have chosen the wide strap (without Stop Cordon), you can put the entire mask in the oven at 90°C (200°F) for 10 minutes.

If you wear the mask in a humid environment, or if you feel decreased breathability, it is possible to increase the oven temperature to 110°C (230°F) for 10 minutes in order to dry the filter ceramic.

WARNING | Do not put the Stop Cordon in the oven as it could deteriorate.

Simple monthly regeneration

of filter cartridges

Type2

CLEANING

Once a month or after storage for more than 4 weeks, it is recomended to soak the PRECIMASK® filtration cartridges in boiling water for 30 minutes. Then, dry in the oven at 110°C (230°F) for 1 hour.

WARNING | Handle the filtration cartridges with care when they come out of the oven so as not to burn yourself and wait for them to cool completely before putting them back on the mask.

Enhanced regeneration

of filter cartridges

Type3

CLEANING

This step is to be applied only to filter cartridges in case of clogging of ceramic filters by dust for example.
