OTBK Portable Mist Sprayer Humidifier for Face & Eyes — Removable Tank, USB-C Rechargeable, Ultra-Fine Mist

OTBK Portable MultiUse Mist Sprayer is a USB-C rechargeable, ultra-fine facial and eye humidifier with a removable tank for easy refills and cleaning.

This compact device delivers a gentle, evenly distributed mist to refresh facial skin and the delicate eye area. Designed for travel, office use, or quick touch-ups at home, it combines a lightweight ergonomic body with a quiet motor and a detachable spray module to keep maintenance simple. The OTBK sprayer is intended for external use with clean, water-based liquids and includes safety features such as a 10-minute auto shut-off.

How fine and even is the mist for facial and eye use?

The sprayer uses a fine-mist nozzle engineered to produce an ultra-fine, consistent spray that sits lightly on skin without dripping. That even dispersion helps hydrate and refresh sensitive areas like around the eyes while minimizing wet spots on makeup or clothing.

• Ultra-fine mist for gentle surface hydration
• Even particle distribution reduces pooling
• Designed for use with water-based facial mists and toners

How long does the battery last and how do I recharge it?

OTBK's sprayer runs about 60 minutes on a full charge, giving plenty of continuous misting for travel or daily touch-ups. Charging is simple via the included USB-C cable, so you can top up from a laptop, power bank, or wall adapter.

• USB-C charging for fast, universal recharging
• Approximately 60 minutes continuous mist per full charge
• Indicator and cable included for convenience

Is it easy to clean and replace parts?

The spray head and tank form a modular assembly that detaches for straightforward rinsing or swapping with a pre-filled spare. A sloped inlet/outlet design helps reduce trapped residue, and the replaceable module keeps long-term hygiene simple.

• Detachable tank and spray head for easy cleaning
• Sloped inlet/outlet to prevent liquid build-up
• Modular spare tanks can be pre-filled for quick swaps

Is the sprayer quiet and safe to use around others?

The unit operates at under 40 dB, making it discreet in open offices, libraries, or shared spaces. Safety features include a 10-minute auto shut-off and guidance to use only clean, non-oily, water-based liquids for external application.

• Runs under 40 dB—suitable for quiet environments
• 10-minute automatic shut-off for safe operation
• Use only clean water-based liquids; avoid oils or corrosive substances
