Putting Salt In Humidifier : is it good ?

Ah, the humble humidifier—our trusty companion through dry winters and stuffy summers. But did you know there’s a little trick to boost its performance? That’s right, we’re talking about adding salt to your humidifier. Before you start pouring your table salt into the tank, let’s dive into the right way to do it.

This blog is your go-to guide for understanding why a pinch of salt might just be the secret ingredient your humidifier has been missing. So, grab your favorite cozy blanket, and let’s unravel the mystery together!

Why to add salt in Humidifier ?

Adding salt to your humidifier’s water tank might seem a bit unusual, but there’s a good science behind it. Here’s why it’s a clever idea:

  1. Boosts Performance: Salt helps the water in your humidifier boil faster, which means it can produce steam more quickly. This makes your humidifier work better and faster, adding more moisture to the air in less time.
  2. Improves Air Quality: Not just about quantity, the quality of steam matters too. Salt can help kill off harmful fungi and pathogens floating around, making the air cleaner and healthier to breathe.
  3. Health Benefits: If you’re dealing with seasonal coughs or colds, adding salt to your humidifier might give you some relief. The saltier steam can be more soothing for your respiratory system, help you breathe easier, and even aid in getting a good night’s sleep. Plus, it’s great for tackling dry skin issues by providing a denser, more beneficial steam.

In short, a little pinch of salt not only ramps up your humidifier’s efficiency but also packs in some extra health perks.

How to put salt in humidifier ?

Adding salt to your humidifier can be done quickly and easily. Just follow these straightforward steps to ensure you’re doing it safely and effectively:

1. Power Off

Start by turning your humidifier off. Unplug it from the wall and also disconnect the power cord from the humidifier itself for safety.

2.Access the Water Tank

Locate and remove the water tank from the top part of the humidifier. If you’re not sure how to do this, take a quick look at the user manual that came with your device for guidance. Before you add any water, give the tank a good clean as per the instructions in your manual.

3.Fill With Water

Pour room-temperature distilled water into the tank. Avoid using water that’s too cold or too hot for the optimal functioning of your humidifier.

4.Add Salt

Now, sprinkle just a pinch of salt into the water. Be careful not to overdo it – it’s better to add too little at first than too much. You can always mix in a little more if needed, but starting with a small amount is key.

5.Mix Well:

Give the water and salt a thorough stir to ensure the salt is fully dissolved and evenly distributed, leaving no clumps.


Put the water tank back in its place on the humidifier.

7.Power On

Plug your humidifier back in and turn it on. You should notice that the mist starts forming more quickly than before, thanks to the addition of salt.

Why Adding Salt to Cool Mist Humidifiers Is Not Advised

Cool mist humidifiers operate on a principle vastly different from their warm mist counterparts; they do not boil water. Instead, these devices generate water vapor through high-speed vibrating plates, which means the water’s temperature remains unchanged.

Since the effectiveness of adding salt is tied to enhancing the boiling process to produce steam more quickly, incorporating salt into cool mist humidifiers serves no practical purpose and will not improve their performance.

Benefits of Using Salt in Suitable Humidifiers

Enhanced Vapor ProductionSalt increases the water’s boiling efficiency, leading to more vapor production and faster humidification of the room air.
Air PurificationSaltwater in the humidifier can help eliminate harmful viruses and germs, ensuring the air in your room is cleaner and safer to breathe.
Skin Health ImprovementMany skin issues arise from dry indoor air. Adding salt water to your humidifier can boost indoor humidity, helping alleviate dry skin problems.
Respiratory ReliefFor those suffering from dry coughs or other respiratory issues, the inhalation of salt-enriched air from a humidifier can provide significant relief.


Adding salt to perticular types of humidifiers can increase their steaming efficiency. By adding salt into the water, it serves as a catalyst, boosting the heating process and leading to increased vapour production. This can significantly enhance the humidifier’s overall effectiveness.

Also The salt brings added benefits such as its bactericidal properties, which aid in purifying the air by eliminating bacteria, viruses, and other harmful microorganisms.

However, it’s crucial to maintain your humidifier by cleaning it regularly, especially if you’re frequently adding salt. A bi-weekly cleaning schedule is advisable for consistent users to ensure optimal performance and hygiene.


Can I add salt to any type of humidifier?

No, you should only add salt to humidifiers designed for heating water, such as warm mist humidifiers. Cool mist humidifiers, which use a different method to generate vapor, should not have salt added to them.

Why should salt be added to a humidifier?

Adding salt to a suitable humidifier can speed up the process of boiling water, thereby creating more steam faster. This can enhance the humidifier’s efficiency and increase the humidity level in your room more quickly.

Are there any health benefits to adding salt to my humidifier?

Yes, salt has bactericidal properties that can help eliminate bacteria, viruses, and other harmful microorganisms from the air. Additionally, the increased moisture can be beneficial for skin health and respiratory issues, such as dry coughs.

How much salt should I add to my humidifier?

Usually, a pinch of salt is sufficient. It’s important not to overdo it, as too much salt can damage your humidifier over time. Start with a small amount and adjust based on the performance of your humidifier.

How often should I clean my humidifier if I’m adding salt to it?

Salt can leave residues that may affect your humidifier’s performance. If you’re adding salt regularly, it’s recommended to clean your humidifier at least twice a week to prevent buildup and ensure it operates efficiently.
