The Best Water for Your Humidifier: The Humidity Hack - Inn Mattress

Are you struggling to get the most out of your humidifier? One crucial factor that many people overlook is the type of water they use in their machines. Not all water is created equal when it comes to humidifiers, and choosing the right type can make a big difference in terms of performance and longevity.

The Importance of Choosing the Right Water

Humidifiers work by adding moisture to the air, which can alleviate dry skin, improve breathing, and reduce snoring. However, if you’re using tap water or hard water in your humidifier, you may be doing more harm than good.

Tap water contains minerals like calcium and magnesium that can build up over time and damage your machine’s internal parts. Hard water can also leave behind mineral deposits that create a breeding ground for harmful bacteria and fungi.

Using distilled or demineralized water instead will minimize these risks and help extend the life of your humidifier. These types of water have been treated to remove impurities like minerals, chlorine, and other contaminants that could clog up your machine or cause health issues.

Types of Water for Humidifiers

When it comes to maintaining a comfortable and healthy indoor environment, a humidifier can be a game-changer. However, choosing the right water for your device is crucial to ensure its longevity and effectiveness. In this article, we’ll explore the three main options for your humidifier: distilled water, demineralized/deionized/ion-exchange resin-treated water, and tap water.

Distilled Water: The Purest Choice

As mentioned earlier, distilled water is one of the safest options for your humidifier. It has been purified through a distillation process, leaving behind pure H2O molecules without any contaminants.


  • Free from contaminants
  • No risk of buildup on internal components


  • More expensive compared to other types
  • Requires extra trips outside the home since not always available at grocery stores

Demineralized/Deionized/Ion-Exchange Resin-Treated Water: A Convenient Alternative

This type of water minimizes mineral oscillations, resulting in less buildup on your device’s components. It’s a convenient option, as it’s readily available at most grocery stores.


  • Less expensive than distilled water
  • Readily available at most grocery stores


  • Some minerals may still remain in the water

Tap Water: Use with Caution

While tap water could be used as a last resort, it’s not recommended for long-term use in your humidifier. It contains more minerals that can deposit on the internal components of your machine, leading to clogs or permanent damage.


  • Readily available and cost-effective


  • Can cause mineral buildup and damage to your humidifier

Distilled water is the safest option for your humidifier, while demineralized/deionized/ion-exchange resin-treated water offers a more convenient alternative. Using tap water should be avoided if possible to prevent damage to your device. Regardless of the water type you choose, always follow the manufacturer’s guidelines and clean your humidifier regularly to ensure its optimal performance.

If you want your humidifier to function correctly and efficiently for longer periods, using distilled or demineralized/deionized/ion-exchange resin-treated should be considered when possible. Although tap water can work at times, its benefits could only last short-term while potentially harming the machine through mineral accumulation internally.

By following this humidity hack, not only will you improve your air quality and enjoy better health benefits from your humidifier but also prolong your investment’s life span thus saving costs over time.
