raydrop: the compact humidifier for the bedside table

Prices in euros from Amazon.de, as of 11 June 2026. Prices and availability may differ on Amazon.co.uk.

By Seydhan Cakmak · Editor-in-chief · Updated: · AI-translated from the German original

The raydrop is a deliberately plain ultrasonic humidifier: rotary knob instead of an app, a 1.7 litre tank and a base only 12 cm slim that fits on any bedside table. It runs quietly at 26 dB, and automatic shut-off at low water level is on board. As an entry-level appliance it scores mainly on price and three years of warranty.

Built for 230 V and EU plugs. In the UK, use with a fused travel adapter; in the US, the device will not run on the 120 V mains.

raydrop 1.7 L Ultrasonic: what works, what doesn't?

What works well

  • Very cheap: a clear price entry among ultrasonic humidifiers, solid basic function with no surcharge for extras
  • Space-saving: only 12 cm base diameter, fits on narrow bedside tables and in tight corners
  • Child's-play operation: one rotary knob controls the mist, no menu, no app, suitable even for the tech-averse
  • Quiet operation: 26 dB disturbs neither sleep nor concentrated work at the desk
  • 3 years warranty: an unusually long warranty commitment for an appliance in this price range

Points of criticism

  • Small tank: 1.7 litres last only around 9 hours on the highest setting, tight for a full night, and during the day you refill more often
  • No automation: no humidity sensor and no timer function documented, and output is regulated manually only
  • No-name brand: support and spare-part supply are hard to assess for this brand, despite the long warranty

Build quality & everyday use

What carries the raydrop 1.7 L Ultrasonic in everyday use: Very cheap (a clear price entry among ultrasonic humidifiers, solid basic function with no surcharge for extras) and Space-saving (only 12 cm base diameter, fits on narrow bedside tables and in tight corners). We have to be honest about the weaknesses: small tank, since 1.7 litres last only around 9 hours on the highest setting, tight for a full night, and during the day you refill more often.

If you set the device up to save space, make sure it stands on a stable, level surface with some air around it. This protects the mechanics and electronics in continuous use.

“raydrop Ultrasonic Humidifier 1.7 L: very cheap and space-saving, and the trade-off is the small tank. At 7.6/10 a fair deal from €20.”
