Solis was founded in 1908 by researcher Wilhelm Schaufelberger in Zurich and has been selling household and professional devices for over 110 years, enjoying great popularity both domestically and abroad. The company's first product was an electric heating pad designed to relieve the founder's pain. The first Solis hairdryer, housed in an unbreakable nickel casing, was developed in 1933 from metal and wood. In 1958, the product range was expanded to include quartz lamps, heating blankets, and an electric coffee grinder. In 2002, Solis introduced a hairdryer with integrated ion technology to the European market. The Swiss traditional company, based in Opfikon with its own production facility in Mendrisio, Ticino, offers a wide range of household appliances in the areas of beauty, wellness, kitchen, and climate. These practical high-end products provide both high quality and useful additional features, as well as timeless design and durability. Years of experience and excellent market knowledge enable Solis to bring innovative and safe products to the market.
