Filtration cartridges

The design and validation has been done with filter cartridges made using sintering 3D printing techniques that ensure that there are no leaks between the possible contaminated environment and the inside of the cartridge.

There are currently more than one 3D version available that are available for public use at the 3D Model link.

Eurecat is working on the injection mold of the filter cartridge and Prometal3D is working on the industrialization of its assembly.


The filtration cartridges are reusable, their useful life is 5 days in masks without exhalation valve.

This useful life of 5 days has been estimated, taking into account the prevention of the appearance of bacterial or fungal cultures due to the moisture accumulated during the hours of use.
