This is the two-in-one Himalayan salt lamp and aromatherapy oil diffuser. As a salt lamp it utilizes the ancient remedy of halotherapy to help treat respiratory ailments. An included 10-watt bulb heats the genuine 100% pink Himalayan salt, which releases charged particles that help allergy and asthma sufferers clear their airways. As an oil diffuser, it uses inaudible high frequency waves to produce a safe, fragrant mist. It is quieter than a whisper and is easily operated by filling the reservoir with water and a few drops of your favorite essential oil (not included). The lamp and diffuser can be operated individually or together. The lamp has five brightness settings and the diffuser covers a 160' sq. room. Includes two bulbs and measuring cup. AC plug. White. 8" Diam. x 8" H. (5 lbs.)
