Can I use regular water with the inhaler?

No. Use distilled water ONLY.  Tap, bottled and filtered water contain minerals that are not compatible with the product.  The product will not work unless distilled water is used. Water not included with product.

IMPORTANT: Please note that using any additives in the water tank, any other liquid or water with minerals (e.g. bottled, purified, or boiled water) will damage the device and will void the warranty.
