Fabric treated with Purotex use microcapsules that contain natural probiotics. Probiotics are a 100% natural remedy against allergenic sleep disrupters. Thanks to friction between your body and the mattress or between your head and the pillow, the microcapsules burst open and start multiplying. The probiotics absorb humidity and start to clean up allergens. Discover Purotex, nature's own technology for a clean, fresh and healthy sleep environment.
