Description from the web:
Salin Plus is an international award-winning medical device that removes airborne pollutants, such as dust and pollen, like traditional air purifiers.
Additionally, it releases tiny therapeutic salt ions, for inhalation, providing a very convenient way for users to benefit from salt therapy while they sleep.
Salin Plus Salt Therapy is a great alternative to using other home devices such as humidifiers, salt lamps, salt pipes, air purifiers, mouth guards or saline sprays.
Friend,
if its actually releasing salt in "ion form" then its releasing chlorine gas.
I seriously question anyone who believes this, you can't just throw a bunch of sciency words together and call it a day. Again, the negatively charged part of salt is chlorine.
The only slightly related use of salt therapy is diagnosing asthma, and thats because it induces bronchoconstriction.
