Best Overall: Xiaomi Smart Humidifier 2 (¥299)

Xiaomi’s evaporative humidifier uses a rotating filter disc system that’s naturally anti-microbial and doesn’t produce the white dust common with ultrasonic models. The target humidity display is accurate, and the Mi Home app lets you create automations with temperature/humidity sensors. At just 32dB on low, it’s quiet enough for the bedroom.

JD Verified Buyer — Yang H. ★★★★★ “This is our third humidifier in 3 years and finally one that works properly. The evaporative type doesn’t leave white dust on furniture like our previous ultrasonic did. Auto mode maintains 50% humidity perfectly. Cleaning is easy—the filter just needs rinsing every 2 weeks. Highly recommend.”

JD Verified Buyer — Wang L. ★★★★☆ “Great humidifier but the water tank is 4.5L—fine for overnight but needs refilling daily in dry winter. The filter disc should be replaced every 6 months at ¥79. The connection to Mi Home dropped twice but was fixed by restarting. Otherwise excellent performance.”

Best Budget: Deerma Humidifier (¥99)

Deerma’s DEM-JS600 is the definition of “good enough.” The 4.5L tank runs all night on medium, the ultrasonic mist is adjustable, and it shuts off automatically when water runs out. No app, no sensors, no fancy features—just effective humidification at a price that makes buying one per room painless.

Verdict

The Xiaomi Smart Humidifier 2 at ¥299 is our top pick for 2026, offering the healthiest evaporative humidification technology and smart home integration at a mid-range price. Budget buyers should go with the Deerma DEM-JS600 at ¥99—simple, reliable, and effective.

Overall Score: 8.5/10
