Humidifiers are a great way to add moisture to the air, but you may wonder if you can use spring water in your humidifier.

The answer is yes! Spring water is a great option for your humidifier because it is naturally filtered and contains minerals that can help improve indoor air quality.

Key Takeaway’s

  • Humidifiers are devices that help to increase the humidity, or moisture, in a room.
  • There are many different types of humidifiers, including spring water.
  • Spring water can be used in a humidifier, but it is important to use distilled or filtered water to avoid damaging the unit.
  • Using spring water in a humidifier can help to improve the air quality in your home and make it more comfortable.

Here’s The Answer To Can You Put Spring Water In A Humidifier

You can technically put spring water in a humidifier, but there are some things you should know before doing so. First of all, spring water typically has a high mineral content.

This can be beneficial in small amounts, as the minerals can help to purify the air. However, too much mineral content can be detrimental to your health.

If you decide to use spring water in your humidifier, clean it out regularly to prevent the build-up of minerals. 

Some spring waters may contain bacteria or other contaminants you don’t want in your home. Generally, it’s probably best to stick with distilled water in your humidifier.

Now that you are aware of the answer to this query let’s discuss the drawbacks of using spring water in your humidifier.

First, spring water contains minerals and other contaminants that can clog the humidifier’s internal components over time.

If you don’t want your machine shutting down on you every few days, use distilled or filtered water instead of spring water in your humidifiers.

Suppose you fill your humidifier with springwater (even after boiling it first). In that case, there’s a good chance you’ll be encouraging the growth of bacteria and mold inside of it because of its high mineral content.

Spring Water Can Contain Minerals And Other Contaminants

You might be tempted to think that spring water is the same as distilled water, but it’s not. Distilled water is boiled and then condensed into a pure form where all the minerals have been removed.

While in some circumstances, this can be useful (like when using your humidifier), it’s not necessary for most users because spring water contains minerals and other contaminants that will make a humidifier work more effectively.

Spring water contains mineral salts that help keep your body at an optimal pH, so bacteria don’t grow on surfaces like in distilled or purified water.

Spring Water Can Also Encourage The Growth Of Bacteria And Mold In The Humidifier

One of the main reasons you should use distilled water in your humidifier is that spring water can contain minerals that can clog the humidifier and make it less effective.

The minerals in spring water promote the growth of bacteria and mold, which is a problem if you plan to use your humidifier around children or pets.

If you decide to use spring water, just be aware that this may cause problems later on with your appliance.

You Should Only Use Distilled Water Or Filtered Water In Your Humidifier

Spring water is not recommended because of its mineral content, which could cause your humidifier to produce an unpleasant odor.

Tap water is also not recommended for the same reason, but if you must use it, let the air out of your humidifier and add some plain white vinegar before putting it in the tap water.

This will help remove any minerals in the tap water so they don’t get into your lungs when you breathe through your nose while sleeping at night.

If You Want To Use Spring Water, You Should Boil It First To Remove Any Contaminants

You should boil spring water before using it in your humidifier to get rid of any impurities. Boil the water for at least 10 minutes before adding it to your humidifier. You can also add some bleach to kill off any bacteria in the container.

Put a pair of gloves on, turn on the stove, and bring a pot of clean water to a rolling boil.

When the water boils, turn off the flame and let it sit overnight so that all of its impurities fall out into the bottom of the pan where they cannot be re-distilled when they are boiled again later on (this will also reduce how much foam forms during this process).

The next day, strain out all solid particles with cheesecloth or an old t-shirt (old T-shirts work great because they have very fine pores) so that only clear liquid remains in its container after straining.

You might be asking, “Why to use spring water in a humidifier?”

  • It’s more expensive than tap water. Therefore, if you enjoy spending a lot of money on things you don’t really need, this is for you.
  • It’s better for you than tap water. If you enjoy spending money and feeling good about yourself (which are not mutually exclusive activities), this also makes sense!
  • The pH level of spring water can be higher than tap water. This means that it may or may not kill off some harmful bacteria that live in your humidifier and make it smell bad. We can’t say with 100% certainty that this will happen, but let’s just say it does happen, so we don’t get sued by someone who used our article for advice on how to create their bio-weapon using nothing but their bedroom fan and bottled H20 from Trader Joe’s (and now we’ve gone too far).

Are There Any Risks Associated With Using Spring Water In A Humidifier?

The short answer is yes. You can put spring water in a humidifier, but you should be aware of the risks associated with doing so.

First and foremost, it’s important to note that while you may not have had any problems when using tap water in your humidifier before now, this doesn’t mean there weren’t any issues.

The fact that you didn’t notice anything out of the ordinary could simply mean that no problems were occurring until now.

Unfortunately, once mold grows inside your machine (and it will), it becomes very difficult to remove without damaging the essential parts of the unit.

What Are Some Alternative Options For Using Water In A Humidifier?

  • Distilled water is the purest form of water. It’s made by boiling water and then recondensing it. All mineral deposits are removed when you boil the water, and only pure H20 remains. If a humidifier uses distilled or filtered water, it will not have to be cleaned as often and can last longer than one that uses tap water.
  • Filtered or bottled spring water can also be used in your humidifier without worrying about cleaning out mineral deposits or white dust from regular tap water (although some people don’t like the taste of these humidifiers). Some bottled waters contain minerals that are good for your skin, so if you have an issue with this, look into using filtered or bottled spring waters instead.


While you can technically put spring water in a humidifier, it is not recommended. Spring water contains minerals that can build up in the humidifier and lead to problems.

To avoid these problems, it is preferable to use distilled water or water that has undergone filtering.

If you like the idea of using spring water in your humidifier, there are other options.

You can boil it first to remove any minerals or contaminants or use distilled or filtered water instead.
