This is a liquid maintenance product bundled with a microfiber cloth. It cannot function as a desktop humidifier.

Our Verdict
This product is not a humidifier. It is a 32 fl oz bottle of water treatment liquid bundled with a microfiber cloth.
You add this solution to your existing humidifier's water tank. It helps reduce lime, scale, and chlorine buildup.
The formula works with ultrasonic and vaporizer humidifiers. It cleans heat rods and transducers to keep mist flowing.
At $19.95, you get a maintenance accessory. You still need a separate humidifier to add moisture to your air.
Buy this only if you already own a humidifier and want to extend its life. It will not humidify your room on its own.
What We Like

- Neutralizes chlorine in tap water for cleaner mist output
- Includes a 14x14 inch microfiber cleaning cloth in the bundle
- Made in the USA with an odor-eliminating formula
- Works with both ultrasonic and vaporizer humidifiers
What Could Be Better
- Not a humidifier. This is a liquid water treatment accessory only
- No mist output, no tank, and no coverage area for any room
- No smart features, controls, or electronic components included
- 32 fl oz bottle will run out and need regular repurchasing
- Does not replace distilled water or proper humidifier cleaning
