Pros and cons

According to our humidifier expert
  • Thanks to the ionization function, you improve the humidity and also clean the air right away.
  • The humidifier has a built-in hygrometer, so that you're always aware of the humidity in the house.
  • With a maximum noise level of 30dB, these humidifiers are more silent than most humidifiers in this price range.
  • You need to replace the water filter at least once per month for optimal use.
  • This humidifier can splash a little and is less suitable to place on a wooden surface.
  • Pets may not like the sound of an ultrasonic humidifier.

Description

With the Medisana AH665, you not only humidify the air in a room of up to 30 square meters, you immediately improve the air quality. This humidifier has an ionizer, which ensures that dust particles become weightier and land on the floor. Very useful, because now you won't breathe them in any longer. This humidifier has an integrated hygrometer that measures the humidity level in your house. You can read the current humidity level on the display. Want to use the humidifier in the bedroom, but not the entire night? Set the timer and the humidifier will switch off after the set time.

Note: if you use the humidifier daily, you have to replace the water filter at least once a month. When using hard water, you need to descale it regularly. Find out how to do that in the manual.

Cheap and basic device with a futuristic look

  • Simple device with the shell designed by a rocket scientist
  • Large water tank and large humidification capacity
  • At the highest setting and relatively cold room, the moisture is not absorbed well, if the stove is at 21 degrees it is no problem.

Recommended!

  • Easy device
  • Quiet
  • Doesn't throw the atomizer high enough, so you sometimes get a wet surface.

Product does what it is supposed to do and does it well and quietly. You do not want to know where the designer of the device has followed his course, but that should not spoil the fun. We'll let them guess the device for what it's for and we've already had the most hilarious options. In short: in addition to moisture, the device also brings pleasure to your home.

  • cheap
  • good
  • simple
  • few options

Simple to operate device that does its job well. Large water tank that lasts a few days. No options such as a hygrometer, but the price is there too. The device is fairly quiet, but you do hear a slight buzz from the small fan.
