Louis Pernat is a passionate and exciting business leader. He drives with great dynamism the daily evolution of his companies. Customer demand at the heart of his priorities, he never neglects the social and ecological aspects of his activity. Example with the Precimask, created during the first confinement.
Industry 360°…
"My name is Louis Pernat, I am the head of the HBP group which comprises 3 entities: Bouverat Pernat specializing in precision machining, NanoCeram, whose business is working with ceramics, and Cecam, a company that develops fastening solutions for soft and composite materials."
Stop the masks thrown on the ground
“The Precimask adventure began during the first lockdown. Our partner called me right in the middle of COVID and said, ‘Listen, I’m fed up with seeing all these masks lying around in the street. Isn’t there a solution to create sustainable filters?’”
I replied, "Deal, let's do it! We'll try to find a solution." It wasn't so simple because during the first test, we managed to filter, but it was difficult to breathe! That's when we joined forces in this great adventure with Saint-Gobain's European research center, in order to find the right compromise between breathability and filtration.
This is how we brought out these famous filter capsules which are the heart of the mask. The adventure was born in this way, and we developed the Precimask in record time.
This mask is durable, since its silicone part can be cleaned with soap and water. For the two capsules that adorn it, just put them in the oven and they are cleaned! It's childishly simple!
The case can be either opaque and dark, or white… And different colors of capsules are available. They can easily be matched to your outfit: they can be a fashion accessory.

Economic, ecological and social
“Most of the components are manufactured locally. The cartridges are made here, at Bouverat Pernat. The assembly is entrusted to Azêta, a social enterprise.”
I am proud of this success, because this mask is the result of a great collaboration. It is economic, ecological and social. You can find all the technical characteristics on the precimask.fr website.
