FHNUVB Cannon Blast Aroma Humidifier: Is This 7-Color LED Vapor Cannon Worth It in 2026?
A fun, cannon-shaped desk diffuser with LED lights and aromatherapy at $19.99, but the tiny 280mL tank limits its use as a serious humidifier.

How this humidifier scores for different use cases
The compact 5.9 x 5.35 x 5.35 inch footprint, quiet operation, and LED lighting make it a solid desktop companion. The 280mL tank can cover a few hours of desk time.
At 13.9 ounces and roughly 5-6 inches in each dimension, it is fairly portable. However, it is not USB-powered and is slightly bulky compared to dedicated travel humidifiers.
The <28dB noise level and 1/3/5-hour timer support overnight use, but the tiny 280mL tank limits runtime severely. You will likely need to refill during the night.
Cool mist and auto shut-off are positives, but no BPA-free certification, no humidistat, and a very small tank make this inadequate for consistent nursery humidification.
At 280mL tank capacity with no coverage area specified, this desktop unit cannot meaningfully humidify a large room. It is designed for personal-space use only.
No WiFi, no app control, no voice assistant support, and no remote control. This product has zero smart home integration capabilities.
Our Verdict
The FHNUVB Cannon Blast is a novelty desktop humidifier shaped like a turret. It shoots mist like a cannon for a fun visual effect. It works best as a small desk accessory.
The 280mL tank is the biggest limitation here. That is just over one cup of water. Expect frequent refills if you run it for more than a few hours.
Quiet operation below 28dB is a real strength. You can place it on your desk without distraction. The 7-color LED adds a nice ambient glow.
Aromatherapy support and a built-in timer round out the feature set. These extras add good value at the $19.99 price point.
This is not a serious humidifier for dry rooms or large spaces. It lacks a humidistat, variable mist, and smart features. Think of it as a decorative diffuser with light humidification.
If you want a fun, affordable desk gadget that adds a little moisture and scent, it delivers. For real humidity control, you need a larger unit.
