All salts are not created equal! There are a variety of types of salts being used in salt rooms including Dead Sea, Mediterranean, Himalayan, Regular Sea Salt, different blends, and pharmaceutical grade salt. Salt is used as décor and salt is used in halogenerators.
Dead sea salt, Mediterranean salts, salt blends, etc… often have trace elements and various mineral content. Depending on the region where the salt is cultivated, there could also be some moisture, clay, and dirt particles that when crushed and ground, could harm the components inside the halogenerator. Likewise, people who have certain respiratory issues could have some adverse effect or reactions to some salts.
All of the validated clinical studies and scientific research for halotherapy involve using pharmaceutical grade salt in the halogenerator. Therefore, S.A.L.T. Chamber, Inc. highly recommends only using pharmaceutical salt for our halogenerators.
The salt on walls and floors do not inherently provide any therapeutic value, except that Himalayan salt in its natural form as bricks or panels, does provide some electrolyzed ions that add to the therapeutic benefit of the treatments.
