Pure Enrichment PureGlow Crystal - 2-in-1 Himalayan Salt Lamp & Ultrasonic Essential Oil Diffuser, Original Salt Therapy Lamp, 100% Pure Himalayan Salt, Ambient Glow, 160 mL 16-Hour Tank (White)

This has been really great! My child had a cough that seemed to last forever. The doctor felt she must just be a more reactive cougher but I wanted it to stop. I wanted to try a more natural solution, and found information on halogenic therapy and decided to give this a try (even though it's not emitting small salt crystals in to the air). Over the last few months, I've noticed a huge difference in her cough! It could be the salt lamp, or it could be that after months to a year it finally cleared up. But I'm happy to keep it and use the diffuser.
