The science behind salty air: how do humidifiers with salt content work for healthier indoor air?

In recent years, awareness of the health benefits of an environment with salty air has increased significantly. People with respiratory conditions such as asthma and allergies in particular are looking for ways to make more frequent use of this healing effect. To this end, more and more spas and recreational areas are being built that are dedicated to the topic of salt. These also include special playgrounds. On the other hand, those who cannot regularly spare the money for such leisure activities are looking for long-term and easily accessible solutions. Humidifiers with salt content offer an interesting option for creating air quality similar to that of the North Sea. But how exactly do they work?


The basics of salt humidifiers

Salt humidifiers also use the principles of salt therapy or halotherapy, which has been used for centuries to treat respiratory diseases. Salt therapy involves inhaling fine salt particles that penetrate deep into the respiratory tract and are said to have anti-inflammatory and antibacterial effects. The focus with household appliances is on simple use and easy cleaning, especially of the surrounding areas. For very few people, lining the living room with salt blocks or a salt carpet is an option.


How humidifiers with salt content work

Many such humidifiers work according to 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, where it is inhaled by the occupants. The fine salt particles are said to offer similar health benefits as the natural salty air on the coast. This type of salt air conditioner is particularly suitable for wet rooms or, if available, a sauna. The salt particles are strongly agitated and circulate throughout the room, settling everywhere as fine dust.

There are also some models that work with a lower salt content and use complex technology to enrich the room air with water and a little salt. Sometimes with fans or via infrared. The fact that these devices usually work with low salt doses is due to the electrical components, which are more susceptible to salt corrosion.


SalinoVatis' Mini Saline

One example of a natural humidifier with brine is the SalinoVatis Mini Saline, which is based on the principle of large graduation towers. 3D printing creates an effecient surface area of around one square meter in a compact form. The device therefore fits on any windowsill, desk, bedside table or corner. The effective area in which the salt air is felt most strongly is approximately a radius of 1-2 meters. It is suitable for rooms between 10-15 square meters to noticeably change the atmosphere of the room. In larger rooms, the effect is less noticeable and might only be felt right next to the appliance.

The device is filled with water and sea salt, and the brine is distributed over the salt tower via an aquarium pump, keeping it in constant motion. This continuous movement means that mold or bacteria are less likely to form in the water. By distributing the brine over the extremely large surface area inside the tower, the air has plenty of contact surface. The water evaporates naturally, releasing 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. This makes it particularly beneficial for people with asthma, allergies or other respiratory conditions. One study that looked at the effect, for example, is the "Effectiveness of Halotherapy in the Treatment of Bronchial Asthma: A Randomized Controlled Trial"
This study was conducted by Chervinskaya AV et al. and investigated the effects of halotherapy (salt therapy) on patients with bronchial asthma and concluded that halotherapy had an anti-inflammatory effect and significantly improved patients' symptoms.


Potential disadvantages of salt humidifiers

Some potential disadvantages should be considered when using salt humidifiers. These include possible corrosion of metallic surfaces by salt particles, the risk of increased humidity and resulting mold growth, the accumulation of salt residues and the risk of unintentional inhalation of salt particles. The last point only affects a small group of people, but it is possible, especially those with cardiovascular problems such as high blood pressure, that increased salt intake can have negative effects. Therefore, to be on the safe side, a doctor should determine the safety of a salt air treatment for oneself before purchasing it. For many people, however, the benefits outweigh the risks and there are simple measures that can be taken to reduce the risk of using a salt air conditioner. For example, choosing the right location, regular ventilation and regular wiping of surrounding surfaces.


Salt humidifiers: Top or flop?

Humidifiers with salt content offer a promising opportunity to utilize the health benefits of salty air indoors. By removing pollutants and improving air quality, they can help to 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 is appropriate to individual needs and circumstances. People with known salt sensitivities or other health problems should always consult their doctor before using such humidifiers.
