Salt is a very versatile substance, with many uses including cooking, spirituality and medicinal purposes. As for salt therapy, there are countless variations and different names to figure out. This isn’t surprising, considering that salt therapy has been around since ancient times.

So, what exactly is the difference between salt caves, home salt therapy and other therapeutic uses for salt? We decided to go over a bit of quick history, to try and ‘clear the air’ about salt therapy.


The first recording of the beneficial usage of salt was in 1843, by a Polish physician named Felix Boczkowski. While he was stationed at a salt mine in Wieliczka, he noticed something different about the miners.

Normally, men working in mines suffer from terrible respiratory problems but Dr Boczkowski saw that the salt miners emerged breathing easy. Such was the official beginning of Speleotherapy, Speleomeaning to be of/inside a cave. Dr Boczkowski’s predecessor started a mineral spa based on these observations. The act of bathing in minerals and salts is known as balneotherapy.

The success of speleotherapy and balneotherapy lead to more and more people considering salt caves as therapeutic. The benefits of natural rock salt inside the microclimate of a cave were numerous, but meant travelling to the cave itself. Eventually, with the advent of modern technology and innovation, home salt therapy was born – giving people the option to experience speleotherapy from home.


Salt therapy devices replicate the conditions of salt caves. They contain rock salt (not table salt) like in salt caves, but are portable and can be used almost anywhere. Of course, to replicate a salt cave, it’s best to use them in a similar environment to a cave. Maintaining a low humidity and closing doors and windows results in the salt particles working to their fullest.

The Salin Plus Salt Therapy Device emits dry salt aerosol made from natural rock salt so you can breathe in microscopic salt particles all night. These devices produce dry sodium chloride (salt) that is negatively charged, which means they are attracted to positively charged surfaces, such as the inner airways.

Salt is essential for life, and is used for the balance of fluids and electrolytes in the body. The dry salt aerosol from the Salin Plus Salt Therapy Device is safe even for those on low-salt diets, and as a bonus, is non-corrosive.

When used outside a cave environment, salt therapy is also known as Halotherapy. Halois Greek for salt. Halotherapy, in its many forms, has been used for millennia.


Salt is a staple of modern life, no matter where you look for it. Epsom salts can be used in baths, isolation tanks, agriculture and even beer. Himalayan salt lamps are thought to have beneficial properties, but without a filter and fan like there is in a Salin Plus Salt Therapy Device, it’s hard to see how the salt moves around the room.

There are so many uses for salt that it’s hard to keep count. After years of successful use of salt by our ancestors for healing and health, we’ve refined the use of salt into a fine art. We now have the knowledge to take advantage of this amazing mineral for our well-being, and in the comfort of our own homes.

Mini Hygrometer & Thermometer
Mini Hygrometer & Thermometer

This device is useful for monitoring the Relative Humidity level in your home. It should be placed along side your Salin Plus device. The ideal RH level is 55%. If the RH level exceeds 70%, there is a risk that your room is too damp and the Salt Filter will absorb this moisture. A damp filter can leak water as well as reducing the effectiveness of the filter. Dust mites thrive when the RH level exceeds 65%. 

It is a very useful device to have in your home, not only to ensure that humidity will not impact the performance of your Salin Plus Salt Therapy Device but also if you are prone to allergies or have reactions to moulds or mites.
