Can You Put Salt In A Humidifier?

The short answer is yes, you can put salt in a humidifier. However, whether you should or not depends on a few factors. Some people add salt to their humidifiers for various reasons, including improving air quality, enhancing the effectiveness of the humidifier, and creating a therapeutic environment. But before you start sprinkling salt into your humidifier, it’s essential to understand the different types of salts and their effects.

Can You Put Saline in a Humidifier?

No, it would be best not to put saline in a humidifier. Saline is a salt and water solution often used for nasal irrigation or as a nasal spray to help relieve congestion and other respiratory symptoms.

Adding Salt To A Humidifier – How Much?

Let’s discuss the various salts you can add to your humidifier and the recommended amounts. Remember that different salts may have varying effects, so choosing the right one for your needs is essential.

Iodized Salt

Iodized salt, the kind you find on your kitchen table, is not the best choice for your humidifier. It contains iodine and anti-caking agents, which can be harmful when released into the air. Please stick to the other salt options we discuss below.

Epsom Salt

Epsom salt, magnesium sulfate, is popular for bath soaks and home remedies. If you’re considering adding Epsom salt to your humidifier, start with a small amount, like a teaspoon per gallon of water. This will help you gauge its effect on the humidifier’s performance and the overall environment.

Sea Salt

Sea salt, derived from evaporated seawater, is another option for your humidifier. It contains trace minerals that can be beneficial for your health. Use about a teaspoon per gallon of water as a starting point.


Himalayan salt, a pink rock salt, is a popular choice for air purification and overall wellness. It’s believed to have numerous health benefits and is often used in salt lamps and salt therapy. When adding Himalayan salt to your humidifier, start with a teaspoon per gallon of water.

What Are The Benefits?

Adding salt to your humidifier may offer some benefits, such as:

  1. Salt therapy: Also known as halotherapy, salt therapy has been used for centuries to help with respiratory issues, allergies, and skin conditions. The salt particles released into the air can help cleanse and purify the air, reducing allergens and irritants.
  2. Improved air quality: Some salts, like Himalayan salt, are believed to emit negative ions when heated or dissolved in water. These negative ions can help reduce pollutants and allergens in the air, making the environment more comfortable for those with allergies or respiratory issues.
  3. Aromatherapy: When used with essential oils, salts can enhance the scent and therapeutic benefits of the oils. For example, a salt and lavender oil mixture can create a soothing and relaxing atmosphere.

I’ve Heard That It Is Good For A Baby

Using a humidifier with salt can benefit babies, especially those with respiratory issues or allergies. The moist air can help alleviate congestion, while the salt can help purify the air, reducing allergens and irritants. As always, consult your pediatrician before introducing new elements to your baby’s environment.

Adding Too Much Salt To Your Humidifier

As the saying goes, “Too much of a good thing can be bad.” Overdoing it with salt in your humidifier can cause some issues, including:

  1. Damage to the humidifier: Adding excessive salt to your humidifier can lead to buildup, clogging, and corrosion, ultimately shortening the life of your device.
  2. Reduced efficiency: Too much salt can hinder the humidifier’s ability to produce the right amount of moisture, resulting in less effective air humidification.
  3. Air quality issues: Excessive salt can cause discomfort, particularly for those with respiratory issues or sensitivities.

To avoid these problems, start with the recommended amount of salt and monitor your humidifier’s performance and the overall environment.

What Humidifier Should I Use With Salt?

Himalayan Salt Diffuser Humidifier

If you want to incorporate salt into your humidifier routine, consider a Himalayan salt diffuser humidifier (available here). These devices are specifically designed to work with Himalayan salt, combining the benefits of a humidifier, air purifier, and aroma diffuser in one handy appliance.

Himalayan salt diffuser humidifiers typically feature a salt chamber where salt crystals can be placed. As the humidifier operates, the salt is dissolved in the water, releasing the beneficial negative ions and creating a therapeutic environment.


In conclusion, adding salt to your humidifier can offer some benefits, particularly regarding air quality and therapeutic effects. However, it’s essential to choose the right type of salt, use the correct amount, and monitor the impact on your humidifier and environment. If you’re interested in combining the benefits of salt therapy with air humidification, a Himalayan salt diffuser humidifier might be the perfect addition to your home.

Remember to keep it friendly and casual, just like we did here, and always prioritize your health and well-being. Happy humidifying!
