Our Himalayan salt inhaler is made of high-quality ceramic and contains food-grade Himalayan pink salt. When you inhale through the mouthpiece, micron-sized particles of Himalayan pink salt enters the respiratory system including sinuses, nasal cavities, throat and lungs. Like gargling & nasal rinses (Meti), inhaling is another way to enjoy the wonders of Himalayan salt in your own home, or on the go. Inhaling the micron-size salt particles cleanses the entire respiratory system.
