The science behind salt air: How do salinity humidifiers work for healthier indoor air?
In recent years, awareness of the health benefits of salty air has increased significantly. People with respiratory diseases such as asthma and allergies in particular are looking for ways to make more use of this healing effect.
Basics of salt humidifiers Salt humidifiers use the principles of halotherapy, which involves inhaling fine salt particles that penetrate deep into the respiratory tract and are said to have anti-inflammatory and antibacterial effects. Household appliances focus on ease of use and cleaning.
How salt humidifiers work Many of these devices work on the evaporation principle. They evaporate water and mix it with a salt solution to create a fine salt mist solution. This is then released into the room and inhaled by the occupants. The fine salt particles offer similar health benefits to the natural salty air on the coast and are particularly suitable for humid rooms or saunas. The salt particles circulate in the room and settle as fine dust.

There are also models that work with a lower salt content and use complex technologies such as fans or infrared to enrich the room air with water and some salt. These devices often use lower salt concentrations to avoid corrosion on the electrical components.
SalinoVatis Mini Saline An example of a natural brine humidifier is the SalinoVatis Mini Saline, which works on the principle of large graduation towers. 3D printing creates an efficient surface of about one square meter in a compact form that fits on any windowsill, desk, bedside table or corner. The effect is noticeable within a radius of 1-2 meters and is suitable for rooms of 10-15 square meters. In larger rooms, the effect is less noticeable and can only be perceived near the device.
The device is filled with water and sea salt, and the brine is distributed over the salt tower via an aquarium pump so that it is constantly in motion. This prevents the formation of mold or bacteria in the water. Due to the large contact surface of the brine in the tower, the water evaporates naturally and releases salt aerosols into the surrounding air.
The Effect on Health Studies show that salty air can have anti-inflammatory and expectorant properties. Breathing in salty air can help clear the airways, loosen mucus and reduce inflammation, which is especially beneficial for people with asthma, allergies or other respiratory conditions. One study examining this effect is "Effectiveness of Halotherapy in the Treatment of Bronchial Asthma: A Randomized Controlled Trial" by Chervinskaya AV et al. The study showed that halotherapy has an anti-inflammatory effect and significantly improved patients' symptoms.
Potential Disadvantages of Salt Air Humidifiers Some potential disadvantages should be considered when using salt air humidifiers. These include possible corrosion of metal surfaces by salt particles, the risk of increased humidity and associated mold growth, the buildup of salt residue, and the risk of inadvertent inhalation of salt particles. In particular, people with cardiovascular problems such as high blood pressure could experience negative effects from increased salt intake. Therefore, a doctor should be consulted to determine the safety of salt air treatment. However, for many people, the benefits outweigh the risks, and there are simple measures to minimize the risks, such as choosing the right location, regular ventilation, and regular wiping of surrounding surfaces.
Salt Humidifiers: Hit or Miss? Salt humidifiers offer a promising way to harness the health benefits of indoor salty air. By removing pollutants and improving air quality, they can improve the well-being and quality of life of people with respiratory conditions. However, it is important to consider potential drawbacks and ensure that the use of such devices fits individual needs and circumstances. People with known salt sensitivities or other health problems should always consult their doctor before using such humidifiers.
