When Distilled Water is Not Available to Fill a Humidifier: What is the Best Second Choice?

It's a common situation: you need to fill your humidifier but distilled water isn't available. Don't fret! There are several excellent alternatives that can work just as well. Let's explore these options and how to use them effectively.

Purified Water

Purified water is a popular choice and is usually sold alongside brands like Spring water. It is water that has been treated to remove impurities, similar to home filtration systems from companies such as Pur. While it may contain trace minerals, it's still safe for use in most humidifiers. Benefit: It's readily available and easy to use.

Spring Water or Bottled Drinking Water

Spring water or any brand of bottled drinking water is another excellent substitute. These varieties do not contain calcium or other minerals that could potentially harm your humidifier. Benefit: It is readily available and doesn't require any special handling.

Reverse Osmosis Water

For a more advanced option, consider Reverse Osmosis (RO) water. This process removes almost all impurities, including minerals. You can find RO water at grocery stores or even at independent aquarium stores. Benefit: It's one of the purest forms of water you can use in a humidifier.

DIY Distilled Water: A Simple Process

For those who prefer to make their own distilled water, it's super easy! Distilled water is created by boiling water into steam and then recondensing it back into liquid form. This process removes all contaminants, chemicals, and minerals, leaving pure H2O. Follow these steps to create your own distilled water:

Fill a large pot 1/4 to half way with tap water. Place a bowl or another pot on top of the water. Ensure it covers most of the middle, as the water will move when it starts boiling. Place a lid upside-down on the pot. Place ice on top of the lid, on the outside. Boil the water. As it boils, the steam rises and gets trapped under the lid, where the ice causes condensation. This condensation gathers in the middle of the lid at the bottom and drips into the bowl. The water in the bowl is now distilled.

Another method to create pure water from tap water is to either boil it without a lid and let it sit out in open air for a day or 3, or leave it uncovered in a container. Both methods will help evaporate impurities and minerals. Benefit: It's a cost-effective solution for those who want to avoid purchasing special water.

Using Clean Springs in Your Humidifier

While tap and purified water are both viable options, it's important to note that impurities can still collect in the humidifier and contaminate the air or lead to mold/fungus growth on the machine. If you use pure water, keep an eye out for discolored or weird films on the machine. Use alcohol or bleach to clean off any mold or fungus that may appear, but be sure to thoroughly rinse the machine before using it again. Benefit: Regular cleaning helps maintain the machine's performance and longevity.

Conclusion

When it comes to finding a suitable alternative for your humidifier, you have several options. Whether it's using purified water, spring water, reverse osmosis water, or even DIY distilled water, there are plenty of choices that can work. Each option has its benefits, so choose the one that best fits your needs and availability. Remember to always maintain your humidifier to ensure optimal performance and longevity.
