How this humidifier scores for different use cases
Built for 1614-2153 sq ft coverage with a massive 6.29-gallon tank, 0.53 gal/h mist output, 12+ hour runtime, and wheels for easy repositioning. This is exactly its intended use case.
This is a large commercial-grade unit standing 43.3 inches tall with no quiet operation feature, no sleep mode, and no night light. Its size and lack of noise-reduction features make it a poor bedroom choice.
No quiet operation, no BPA-free certification, no night light, and no humidistat for precise humidity control. The large industrial design is overkill and potentially noisy for a nursery.
At 43.3 inches tall and 14.77 lbs, this is far too large for a desktop. It has no USB power option and is designed for commercial spaces, not personal desk use.
No WiFi control, no app control, no voice assistant integration, no remote control, and no timer. It uses only a manual mist adjustment knob with zero smart features.
At nearly 15 lbs and over 43 inches tall, this is a floor-standing commercial unit with casters. It is completely unsuitable for travel or portable use.
Our Verdict
The Treliamd 6.29-gallon humidifier is a workhorse built for big spaces. It pumps out 0.53 gallons of cool mist per hour and covers over 2,100 sq ft.
You can fill it from the top or connect it directly to a faucet. The tap-fill feature saves you from hauling water back and forth. That alone makes this unit stand out for commercial use.
Four rolling casters let you move it from room to room. At 43.3 inches tall, it sits on the floor like a small appliance. The extension tube helps direct mist where you need it.
Here is where it falls short. You get zero smart features. No WiFi, no app, no remote, no timer. You control everything with one manual knob.
It also lacks a humidistat. You cannot set a target humidity level. You must guess or buy a separate hygrometer.
This humidifier fits greenhouses, warehouses, large offices, and open-plan homes. It does not fit bedrooms, nurseries, or desks. Buy it when you need raw mist power for a big space.

Yes. It includes a water inlet hose that connects to your tap for automatic refilling. You can also fill it from the top.
Does this humidifier have a built-in humidity sensor?
No. It does not have a humidistat or humidity display. You adjust mist output manually with a knob and would need a separate hygrometer to monitor room humidity.

What happens when the water runs out?
