Reviews last updated: August 2026 · How we calculate this

What we like about Airymium 501 Yellow

  • Serves well as both an air humidifier and an essential oil aroma diffuser
  • Easy to operate with straightforward controls and an included remote
  • Quiet ultrasonic operation makes it highly suitable for bedrooms and sleeping
  • Provides a steady, continuous aroma mist that effectively hydrates dry air
  • Visually appealing yellow finish and decorative appearance accent the room
  • Offers great value for money
  • Features a versatile 7-color changing LED light mode that doubles as a night light
  • Includes useful timer settings and a safe automatic shutdown feature when water runs out

What we don't like about Airymium 501 Yellow

  • Receives mixed feedback regarding long-term durability
  • Some users report intermittent functionality or the unit turning off prematurely
  • The 400ml tank capacity requires more frequent refills compared to larger whole-house humidifiers
  • Color variations can occasionally differ slightly from what is expected or advertised

Verdict

The Airymium 501 Yellow is a compact 2-in-1 ultrasonic cool mist humidifier and aromatherapy essential oil diffuser featuring a 400ml water tank, 3-watt power consumption, and a lightweight plastic, BPA-free construction measuring 17 x 17 x 13 cm. Main advantages include a quiet operating system suitable for bedrooms or offices, dual continuous or intermittent mist settings, a 7-color changing LED night light, up to 10 hours of runtime, and an automatic waterless shut-off feature for safety. On the downside, its smaller capacity requires more frequent refills than full-sized home units, it is limited to a coverage area of roughly 15 square meters, and the plastic construction may feel less premium compared to high-end alternatives.
