HODOmask KIDS has the same technical features as HODOmask, but in a size suitable for children; the mask is composed of 5 layers and uses a PTFE nano-porous membrane as a filtering material, made with a unique technology called HYPROOF. The HYPROOF technology allows for a high porosity structure (nano pores) with irregular permutation, ensuring the filtration of more than 95% of particulates down to 0.3µm. It is therefore the ideal companion for protection against fine dust, bacteria, and smog! HODOmask KIDS! It is NOT PPE, NOR a medical device.
