Himalayan Salt works like an air purifier. Heating the salt with a tea light candle releases negative ions into the air, creating an effect similar to an ionizer, purifying the surrounding air. Once lit the candle holder will emit a calming Amber color. Comes with a Yankee Candle Juicy Citrus & Sea Salt tea light. Notes of orange and grapefruit. Burn time 4-6 hours.
