Our Verdict
This product is not a humidifier. It is a water treatment additive for humidifiers you already own.
The Plexon 3US kit includes two 32 oz bottles of ultrasonic humidifier water treatment and one microfiber cloth. You add the liquid to your humidifier's tank to fight lime and scale.
It helps clean heat rods and transducers inside your existing unit. This can extend your humidifier's life and keep mist output strong.
The formula also neutralizes chlorine in tap water. This reduces chemical smells in the mist your humidifier puts out.
At $21.95 for two bottles, the price is reasonable for a maintenance product. But you still need a separate humidifier to get any humidity.
Buy this only if you already own an ultrasonic humidifier and want to keep it clean. It does nothing on its own.

- Helps prevent lime and scale buildup inside ultrasonic humidifiers.

- Neutralizes chlorine in tap water to reduce chemical odors in mist output.
- Two-pack of 32 fl oz bottles gives you a long supply of treatment solution.
What Could Be Better
- This is not a humidifier. It is a water treatment additive and cleaning accessory.
- No mist output, no tank, and no coverage area since it produces no humidity.
- No safety features like auto shut-off because it is not an electronic device.
- No smart features, app control, or voice assistant support of any kind.
- Cannot replace a humidifier for any use case including sleep, nursery, or office.
