PITTA MASK is an anti-pollen mask made of soft stretch polyurethane. Using a new variety of polyurethane material it reaches a new level of wearability causing no discomfort to the ears, even when worn for extended periods of time, and fits snugly to the contours of the face, blocking the gaps through which pollen might get in. This polyurethane material has a steric mesh structure which controls its cells, making them the optimal size and density for catching pollen, while adopting a porous filter technology which perfectly clears the cell membranes that can block breathability. This achieves what might appear to be conflicting functionality with 99% pollen filtering, and high ventilation performance making it extremely easy to breathe. It can be reused after washing, and maintains a rate of 99% pollen filtering even after the third wash.
