What Kind Of Water To Use For Humidifier?

To get the maximum effect from your humidifier, you need to choose the best type of water. Let’s look at what types of water are best for your humidifier.

Humidifiers can be very useful during the dry season. It helps keep your sinuses healthy and your airways moist, especially if you have asthma or allergies that cause inflammation of the mucous membranes.

In addition, humidifiers are able to add moisture to dry air, making them ideal products for the home during the cold months.

However, to get the maximum effect from your humidifier, you must also select the best water type for it. Let’s look at what water types are best for humidifiers and how the water types should affect this device.

Explanation of Types of Water for Humidifiers

Humidifiers work by increasing the humidity in the air. It can be divided into two types: hot mist humidifiers and cold mist humidifiers.

A warm mist humidifier is a type of device that heats the water before turning it into steam, while a cold mist humidifier turns water into tiny droplets without first heating it. The former is believed to work better than the latter and works by mixing different types of water with liquid glycol.

The good news is that for health reasons, hot and cold mist humidifiers work almost equally well, so you can simply choose the type that best suits your needs. It should be noted that the cold mist humidifier produces a little more white powder due to operational reasons, but this is not a big problem.

Can tap water be used in a humidifier?

Tap water is not the best choice for a humidifier. Because it contains chlorine and other impurities that can damage the humidifier and cause health problems.

what kind of water to use for humidifier

Tap water damages electronic devices due to its mineral content. In general, using tap water in a device is not recommended if you want to extend its lifespan.

When tap water evaporates, minerals are formed that can damage the humidifier. In addition, tap water becomes very hard in winter and therefore needs to be cleaned more frequently to prevent mineral deposits on appliances and furniture.

However, if you need cheap water for your humidifier or don’t want to spend a lot of money on distilled or purified water, filtering can reduce the damage. However, we still advise against using tap water in the humidifier.

Best Types of Water for Humidifiers

Distilled Water

Distilled water is not only the best water for humidifiers, but it’s also actually better than hard tap water (which contains chlorine and minerals) because it contains no impurities. Because of this, distilled water is considered the best water for humidifiers. You can buy it in supermarkets.

Distilled Water

Please note that many humidifier manufacturers recommend that you only use their own products to clean their devices, so you will need to use a specific cleaner for your device if necessary.

Also remember that distilled water has a very low pH level which can lead to the deterioration of materials such as limestone, marble, and even wood. Using distilled water without proper care can also damage fireplaces and grills.

A distilled water humidifier is therefore an ideal option for anyone who doesn’t want to damage their home or has expensive household appliances.

Distilled water is preferred in a humidifier for several reasons:

  • It is completely sterile, making it the safest type of water for a humidifier.
  • distilled water is stronger than filtered tap water, which speeds up the humidifier’s cleaning process.
  • Since distilled water contains no minerals, the humidifier does not need to be cleaned as often as with hard tap water.
  • distilled water evaporates faster than other types of water, which means less ammonia builds up.
  • However, distilled water also has some disadvantages:
  • It is very expensive in the supermarket (on average, a liter of distilled water costs $0.50). You can save that if you buy water still for your home.
  • A small amount of minerals in water is good for health as it prevents osteoporosis, tooth decay, and other health problems.
  • Distilled water can dry out skin and hair due to its low pH.

Purified Water

Purified Water is also a good option for a humidifier. It can be easily made at home or bought from the supermarket and contains no chlorine, fluoride or other contaminants found in tap water.

Purified Water

However, sometimes an additional filtration system is required to get better results out of the water. Also, purified water has a slightly higher pH than distilled water, which can be a problem with some materials.

It should be noted that purified water often contains minerals, so it is excellent for plants. Distilled and purified water is the best choice when you need the best-performing humidifier but don’t want to damage expensive items in your home.

Deionized Water

Deionized water is almost identical to distilled water. Deionized water is commonly used in medical care and for cleaning teeth, but it can also be used in a humidifier.

Deionized Water
If you don’t want to destroy your expensive equipment, demineralized water might be the best choice for you. It contains no minerals and has far fewer bacteria than tap water (the bacteria are still there, but the amount is much lower). Tap water).

However, it is possible to clean the humidifier more frequently because the demineralized water evaporates very quickly.

Demineralized Water is also one of the best options for those who need maximum performance from their humidifiers and want to stop using them due to mineral buildup.


It is important to use the right type of water in the humidifier. Tap water contains minerals that can collect on the humidifier and release dust into the air. To avoid this, choose distilled, demineralized, or purified water instead.
demineralization cartridges or filters that can also be used in the room humidifier; These help to reduce limescale deposits and machine dust.
