Using Salt in a Humidifier


By: Evan Scoboria, Last updated: June 28, 2023

Adding salt to a humidifier can help alleviate respiratory issues and improve air quality by creating a humid environment that soothes dry nasal passages and eases allergies and asthma symptoms. Different types of humidifiers require various methods for adding salt, and it's essential to use pure, non-iodized salt and follow manufacturer instructions to avoid damaging the humidifier. Salt therapy involves inhaling salt particles and has been credited with numerous health benefits for respiratory and skin conditions.

Why Add Salt To Your Humidifier?

The benefit of adding salt to your humidifier is that it can help alleviate respiratory issues and improve overall air quality. Salt particles attract water molecules, evaporating into the air and creating a more humid environment. This can help soothe dry nasal passages and ease allergies or asthma symptoms. A study published in the International Journal of Occupational Medicine and Environmental Health found that adding salt to a humidifier can also reduce the concentration of airborne bacteria.

What Types of Humidifiers Can You add Salt To

You can add salt to an evaporative humidifier. Adding salt to the water in an evaporative humidifier can help prevent the growth of bacteria and other microorganisms. The salt also helps to keep the humidifier clean and free from mineral buildup. 

You cannot add salt to an ultrasonic humidifier. Ultrasonic humidifiers use high-frequency vibrations to create a fine mist, and adding salt to the water can cause the mist to become too heavy and clog the machine. Additionally, the salt can damage the ultrasonic membrane and shorten the humidifier's lifespan. 

You cannot add salt to a warm-mist humidifier. Warm-mist humidifiers boil water to create steam, and adding salt can cause mineral buildup on the heating element. This can lead to reduced efficiency and potentially damage the humidifier. It's best to use distilled water in a warm-mist humidifier to prevent mineral buildup.

What Type of Salt to Add to a Humidifier

You should only add pure, non-iodized salt to a humidifier. This is because iodized salt contains additives that can clog the humidifier and potentially release harmful chemicals into the air. Using table salt or sea salt can also lead to mineral buildup and damage the humidifier. It's essential to read the manufacturer's instructions and use the recommended type of salt to ensure the safe and effective use of the humidifier.

In addition to non-iodized salt, a few other types of salt are considered safe for use in humidifiers. It's important to note that the choice of salt can have varying effects on the operation of your humidifier and the quality of the mist it releases.

  1. Epsom Salt: Epsom salt, or magnesium sulfate, is a commonly used humidifier option. However, prolonged use can leave a white residue around the humidifier. Clean the humidifier regularly if you choose to use Epsom salt.

  2. Himalayan Pink Salt: Known for its distinctive color and supposed health benefits, it is another option. It contains numerous minerals and is free of additives, which makes it a suitable choice for use in a humidifier. Be aware, however, that the minerals present in Himalayan pink salt might contribute to a buildup in your humidifier over time.

  3. Rock Salt: This type of salt is typically free of additives, making it a good option for use in a humidifier. However, it's essential to ensure the rock salt is finely ground before adding it to the humidifier to avoid damaging the unit.

  4. Kosher Salt: Kosher salt is a pure salt that doesn't contain iodine or anti-caking agents. Its coarse structure allows for slower dissolution, which may benefit the overall operation of the humidifier.

Always check the manufacturer's instructions before adding anything to your humidifier. The incorrect type of salt or an excessive quantity could lead to problems, such as clogs or the release of harmful particles into the air.

How Much Salt to Add to a Humidifier

The salt concentration in a humidifier should be one teaspoon per gallon of water. To achieve this, measure the appropriate amount of salt using a teaspoon and mix it thoroughly into a gallon of water. It's important to note that too much salt can damage the humidifier, so measure carefully. Once the salt is mixed in, pour the solution into the humidifier and operate as usual. Regularly checking and adjusting the salt concentration can help keep your humidifier running smoothly and effectively.

How to Add Salt to a Humidifier

Add salt to your humidifier by following these simple steps:

  1. First, make sure that your humidifier is designed to use salt. Only some humidifiers are compatible with salt, so check the manufacturer's instructions or consult a professional if you need clarification.
  2. Next, fill your humidifier with water as you usually would. Be sure to use clean, fresh water to avoid any buildup of bacteria or other contaminants.
  3. Add a small amount of salt to the water. The exact amount will depend on the size of your humidifier and the manufacturer's recommendations. Still, a general rule of thumb is to use about one tablespoon of salt per gallon of water.
  4. Stir the water to dissolve the salt. You may need to wait a few minutes for the salt to dissolve fully.
  5. Turn on your humidifier and adjust the settings as needed. You should notice a difference in the humidity level of your home or office within a few hours.

Adding salt to your humidifier can help to improve the quality of the air you breathe, especially during dry winter months. Follow these steps carefully to avoid damaging your humidifier or potential health risks.

Health Benefits of Salt

Salt therapy has been credited with numerous health benefits. It involves inhaling salt particles in a controlled environment, which can help alleviate respiratory issues such as asthma, allergies, and bronchitis. The salt particles can also help clear mucus and reduce inflammation in the airways.

Furthermore, salt therapy has positively affected skin conditions such as eczema and psoriasis. The salt particles can help exfoliate and detoxify the skin, leaving it feeling smoother and more hydrated.

In addition, salt therapy has been found to have a calming effect on the nervous system, which can help reduce stress and anxiety. It can also improve sleep quality and promote relaxation.

Salt therapy is a natural and non-invasive way to improve respiratory, skin, and overall well-being.
