TECHNICAL DATA
Unique, durable and patented ceramic particle filtration system with a filtration level equivalent to a surgical mask (greater than 95% of 3 µm aerosols) and high breathability. No more filter changes to be expected, because the filter cartridges can be cleaned.
100% transparent mask in front of the mouth, with anti-fog and anti-scratch treatment, in order to see facial expressions. Thanks to its biocompatible silicone design, PRECIMASK® is a comfortable mask and allows maximum sealing. It incorporates a removable visor for full protective power.
The materials used for the design of PRECIMASK® have been specially selected for their great stability over time, capable of giving it optimum durability. These materials are also very easy to clean, fully reusable and generate minimal waste as no additional consumables are required.

Maintenance
For the mask and filter cartridges, daily disinfection :
the cartridges placed in the oven at 90°C/200°F (th.3) for 10 minutes, the rest of the mask is cleaned with hot soapy water, or with a virucidal cleaning solution.
Once a month, simple regeneration of the filter cartridges :
soak them in boiling water for 30 minutes. Then dry in the oven at 150°C/300°F (th.5) for 30 minutes.
