PRECIMASK - Version Air et cartouches filtrantes
PRECIMASK® is an innovation designed and manufactured by French manufacturers.

A unique patented ceramic-based filtration system providing filtration efficiency equivalent to surgical mask (higher than 95% for 3 μm aerosols) protecting the wearer and their environment. The excellent permeability of the filter cartridges ensures  very high breathability level. No more filter replacement as the ceramic filter is durable and can be cleaned.

PRECIMASK® is made of a silicone that is flexible, translucent, light and biocompatible, which gives it a reinforced seal and optimal comfort.

The materials used for the design construction of PRECIMASK® have been specially selected for their great high stability over time to provide optimal durability. These materials are also very easy to clean, fully reusable and generate a minimum of waste since no additional consumables are required.

Available in three sizes S, M and L for € 99 incl. € 49 incl.

For the mask and filter cartridges, daily disinfection :
the cartridges placed in the oven at 90°C (200°F) 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 110°C (230°F) for 1 hour.

Never dismantle the integration capsules, their role is to protect the filter element and thus prevent damage to the filter medium.
