Air-O-Swiss AOS 7147

Air-O-Swiss needs no introduction in terms of their presence on the market with electrical goods, and the AOS 7147 cool/warm mist humidifier certainly doesn’t disappoint. It’s sleek in design, covers an area of up 650 sq ft and comes with many up to the minute technological features. The mist system with this model is such that the minute it’s released into the air it dissipates, leaving the room with a clean and fresh feel.

Review Details

One of the best features with the AOS 7147 is the Intelligent Temperature Compensation system which is unique to Air-O-Swiss. This means the mist produced is automatically set to the temperature in the room and the unit will adjust as the temperature changes, all without the need for human intervention.

It also has surface touch controls and comes complete with a sleep mode so the unit can pre-determine what level of humidity will make for a comfortable night’s sleep. You can also make use of the timer, which can be set for continuous use from 1 to 8 hours.
Quiet operation is also something that the AOS7147 rates high on. It uses ultrasonic high frequency vibrations that can barely be heard.

What We Liked

  • Advanced Humidification
    ITC technology monitors the ambient temperature in the room. It also has a replaceable demineralization cartridge which ensures the mist produced is free from mineral deposits.
  • State of the Art Design
    The AOS 7147 is sleek in design and will fit into any type of decor with ease. It comes with surface touch controls that are very simple to use.
  • Performance and Energy
    This unit uses the latest in technology, ensuring it’s one of the most energy efficient models on the market. The humidistat included is incredibly accurate and operation is quiet enough so as not to disturb sleep.
  • Ease of Use
    With one touch of a button the level of humidity can be set, and the mist can either be warm or cool. All that’s required is for the user to set what they would like and the unit will do the rest.

What We Didn't Like

  • No Fill Line
    The tank on this model does not have a fill line, which can make it easy to overfill. However, the tank is clear so it is possible to see how much water it’s holding.
  • Setting Controls
    Whilst the AOS 7147 does have pre-set controls, it won’t remember them each time the unit is powered up. The reason for this is that the settings used before may not be the same.


The design of the AOS 7147 suits what everyone has come to expect from Air-O-Swiss. With automatic settings and simple to use one-touch controls, there is little need for human intervention.
The Air-O-Swiss 7147 ranks very high in terms of performance, ease of use and reliability. The ITC technology used is one of the most advanced on the market, allowing for both cool and warm mist humidity.
