Our salt booth contains highly concentrated medical grade salt particles. The salt will spray out of the filter every minute for 5 seconds filling the booth with salt. The more salt you breath in through your nose and mouth, the better results you’ll get. The salt kills bad bacteria in your lungs, airways and sinus passages. It breaks down mucus on your chest and in your sinus passages so it’s normal to cough, sneeze and blow your nose. If you have any skin conditions it is great to expose your skin to the salt as it also kills bad bacteria on the skin and reduces inflammation. It can help alleviate eczema, psoriasis, rosacea and prevent future flare ups. If you are using the salt booth for cold and flu or respiratory conditions you can be fully clothed in what you feel comfortable wearing. The salt booth is completely safe for children and babies and is big enough to fit 2 people or 3 kids.
