Best Dehumidifier for Basement

best dehumidifier for basementDehumidifiers are a necessary appliance for many homes, but not all are equally suitable for the stickiest conditions and higher humidity in many basement areas – so what is the best dehumidifier for basement duty?

Before we get to our picks, let’s quickly go through what we consider to be important criteria for a basement dehumidifier:

  • High Capacity.  Unless you have a very tiny basement, chances are you will need at least a 50-pint or 70-pint model to really dry the air and keep humidity at desired levels. And when in doubt, it’s usually best to go for a larger capacity unit since they tend to operate more efficiently and can simply shut off when the selected humidity level is reached. If you err on the smaller side, your unit may not be able to bring humidity down sufficiently and/or may be forced to run it continuously 24 hours a day, which may cause the dehumidifier to burn out or fail prematurely.
  • Good Digital Humidistat.  Good electronic controls are crucial for any dehumidifier, and this goes doubly for a basement model that hopefully will need very little monitoring. Although most newer models come with a digital humidistat, they vary in accuracy and reliability.
  • Automatic Defrost. Once temperatures start approaching 50 degrees Fahrenheit, most compressor-driven dehumidifiers become vulnerable to freezing up. As a result, most newer models have an automatic defrost cycle that allows them to work down to temperatures in the low 40s, although this will vary depending on the model.
  • Automatic Restart.  This is an important feature that ensures that the unit resumes operation in the event power is interrupted for whatever reason. After the power returns, the unit should turn itself on a continue working with the same settings it was working under before the outage.
  • Reliable Continuous Drain.  Unless you want to be manually dumping condensate ever few hours or days, you will need to connect the dehumidifier to an existing drain, sump, or any other convenient outlet. There are two types of continuous drain systems, those with pumps and those that are simply gravity draining. Gravity draining systems are not as preferable just because the drain has to be lower than the collection bucket to work, and there is only so far gravity will take the condensate, so you normally have fewer options as far as which drains are available. Pump-type drains, however, are powered and therefore can send condensate over longer distances, horizontally and vertically, so you have a lot more flexibility with respect to finding a suitable drain outlet.
  • Outstanding Reviews & Ratings.  This is obvious, but because we are looking for a basement dehumidifier, we are not so much concerned about sound as we are performance and how well the unit works with little or no supervision.

So what’s the verdict??
