Should You Use Distilled Water in Humidifiersの全貌を詳しく解説してご紹介します。

Use distilled if: you have a cool-mist ultrasonic humidifier, you hate cleaning, or you notice white dust on your electronics. Also, if you have respiratory issues like asthma, the purest air might be worth the extra cost.

Skip distilled if: you have an evaporative model, you’re on a tight budget, or you’re diligent about weekly vinegar cleanings. Tap water is a perfectly fine, low-impact choice for many setups.

The real secret? It’s not just about the water—it’s about the habit. A clean humidifier with tap water beats a dirty one with distilled, every single time.
