The idea of the Delphin multifunctional cleaning system comes from a father of a child with severe allergies. The father, Mr. Helmut Grassinger could not stand no longer about his son suffering from allergies so he established Proair in Allgaeu, Germany. Since 1993, he puts all his efforts and the rest of his life in building the new home-cleaning concept, satisfying people's wishes and to ensure that no more allergies exist by replacing the traditional cleaning methods. Today, the Delphin multifunctional cleaning system has been successfully sold to multiple countries around the world.
