How this humidifier scores for different use cases
Full smart home integration with dedicated app, Alexa, and Google Assistant support. Offers scheduling, humidity control, and remote operation via 2.4GHz WiFi.
The 30dB noise level, 24-hour runtime, auto shut-off, and night light make this a strong bedroom pick. The 3L tank gets you through the night without refilling.
Compact 7.26-inch footprint and quiet operation fit a desk well. App control lets you adjust settings without leaving your task. The 3L tank lasts a full workday.
Cool mist only, auto shut-off, and quiet 30dB operation suit a nursery well. However, no BPA-free certification is listed, which is important for baby-focused products.
The 300 sq ft coverage and 3L tank are modest for large rooms. This unit works best in single medium-sized rooms, not open floor plans or whole-home use.
At 2.8 lbs and nearly 12 inches tall, this is not a travel humidifier. It requires a wall outlet and is too bulky for packing in luggage.
Our Verdict
The CLEVAST CL-HD022 stands out as a smart humidifier at its price point. You get full app control, Alexa, and Google Assistant in a compact 3L package.
The 30dB noise level keeps your bedroom quiet at night. A 24-hour runtime means you fill it once and forget about it until tomorrow.
The 7.1-inch top-fill opening is one of the widest in this size class. You can fill it under any faucet and wipe the inside clean with ease.
The separate aroma box is a smart design choice. Your essential oils stay off the ultrasonic plate, which helps the unit last longer.
This humidifier covers up to 300 square feet. That works for a bedroom or office but falls short for a living room or open layout.
You miss out on warm mist, which some buyers want during winter months. The 3L tank is average for this category.
If you want smart features in a bedroom humidifier without paying premium prices, this CLEVAST model delivers where it counts.

How long does the CLEVAST humidifier run on a full tank?
The 3L tank provides up to 24 hours of continuous mist on the lowest setting. Higher mist levels will use water faster.
Can I use essential oils in this humidifier?
Yes. It has a separate aroma box with two included aroma pads. Add 2 to 3 drops of essential oil to the pad, not directly into the water tank.
Does this humidifier work with 5GHz WiFi?
No. The CLEVAST smart humidifier only connects to 2.4GHz WiFi networks. Most routers broadcast both 2.4GHz and 5GHz bands.
How loud is this humidifier?
It operates at 30dB or less. That is quieter than a whisper and will not disturb sleep in a bedroom or nursery.
What happens when the water runs out?
The humidifier pauses mist output and flashes a red light. It also sends an alert to the CLEVAST app. If you do not refill within 40 seconds, it shuts off automatically.
