SPT SD-31E Dehumidifier
The SPT SD-31E Dehumidifier is a smaller model of the brand’s 70 pint Dehumidifier that only collects 30 pints of water per day. The Dehumidifier works by removing excess moisture in the air and converting it into water through the filter. Removing moisture in the air is an efficient way of preventing mold and mildew from growing within your home. It also helps protect your home from any unwanted airborne bacteria. This is a must have type of product for anyone who lives in a place with high humidity levels.


  • Collects up to 30 pints of water per day.
  • Has a Continuous Dehumidifying setting between 35-85%, which helps to meet any of your need and requirements.
  • Is capable of using a Continuous Drainage System, which requires you to a have a nearby suitable drainage point, as well as a hose, which is not provided.
  • Includes Memory IC, this remembers your previous settings, so that when you turn it back on it automatically goes back onto the previous setting.
  • Also includes an indicator to notify you when the Dehumidifier is full and needs to be emptied.
  • Weighs only 29lbs.


  • It comes with a normal speed as well as a turbo speed, to remove the moisture in the air even quicker.
  • Includes a built-in timer, so that it can turn on at certain times of the day, even when you are out.
  • The Memory IC is very useful for when you are using the timer, as you don’t have to worry about the settings that it has come on at.
  • The filter is also easy to remove, and can be cleaned quickly and easily.
  • Equipped with wheel casters for easy mobility.


  • It does not collect as much water as some of the other dehumidifiers do in a single day (you can check out our to see models with higher capacity).
  • When on turbo speed it is quite noisy and distracting when compared to the normal speed.
  • Just like with every other Dehumidifier, the Continuous Drainage System is difficult to set up.
  • The collection bucket is not designed very well as it can be difficult to take in and out, this can result in you spilling the water, as there is very little extra room in the bucket when it is full.


Overall, this dehumidifier has some issues regarding the collection bucket. I would only recommend this if you are going to use this with the Continuous Drainage System, and if you are not in a extremely humid location, that won’t need to take more than 30 pints of water in a day. If you are in a more humid climate I would recommend looking at the SPT SD-71E Dehumidifier.
