NewAir ADS-400

The NewAir ADS-400 has been specifically designed for those of you that wish to stop your clothing, shoes and furnishing suffering the damage humidity can cause. Compact in design it will easily fit into a closet or under a counter. Unlike many other models in this bracket it is also deemed safe to use in your bathroom. Due to the technology used by NewAir this model is also quiet enough to dehumidify a nursery or small bedroom.

Review Details

Many larger dehumidifiers will use both a compressor and refrigerant to aid in the removal of moisture from the air. NewAir however has designed the ADS-400 using thermo-electric peltier technology that needs neither of these. This means whisper quiet operation without any vibration.

The ADS-400 is perfect for small spaces that have a relative humidity of 80% and will remove up to 10 ounces of water per day. The water tank has a capacity far larger than this (32 ounces) and is easy to remove. It also has an automatic power-off feature when the tank is full, preventing unwanted spillages.
Additionally this unit comes with a recessed carrying handle, and included is a car kit for effective dehumidification while you’re on the move.

What We Liked

  • Advance Noise Level Technology
    This little dehumidifier doesn’t use either a compressor or refrigerant. Instead NewAir has adopted thermo-electric peltier technology which makes for whisper quiet operation (perfect for a nursery or small bedroom).
  • Perfect for Small Spaces
    The ADS-400 will keep areas such as closets, nurseries, small bedrooms and other enclosed spaces free from the damage humidity can cause. Compact in design, it will not take up much space and can be left to quietly dry the air.
  • No More Spills
    The ADS-400 will automatically power off when the tank is full, preventing unwanted spillages. It’s also very easy to remove the tank and empty it.
  • Additional Features
    This model couldn’t be easier to transport with recessed carry handles, and the manufacturer has also included a car kit for effective dehumidification on the move.

What We Didn't Like

  • Effective Moisture Removal
    There have been complaints the ADS-400 is not very good at moisture removal however, the consumer should be aware this unit has been designed for very small spaces and will only remove up to 10 ounces of water per day.
  • Flimsy Design
    The ADS-400 may appear flimsy in design, and there have been complaints that some of the cosmetic features are not very durable.


If you have a mild problem with humidity in small areas or need to clear steam from a small bathroom, the ADS-400 is more than up to the job. It has been revered for its quiet operation making it perfect for the nursery. Given the thermo-electric peltier technology NewAir has used, maintenance is not a problem with this unit. Portability is also easy and considering it comes with a car kit we consider it a very good buy.
