Top 5 Dehumidifiers For Basement Reviews
When you combine performance and price it just doesn’t get any better than this 70 Pint unit from Frigidaire. This is the best dehumidifier for basements. You can easily set the exact desired humidity via the electronic panel on the top of the unit.
It has a 13 Pint water reservoir that’s easy to pull out and empty but this dehumidifier also supports continuous drain function and that’s the way we’d go. Buy a hose (it doesn’t come with one) and connect it to the outlet of the unit and then run the hose into a drain. It doesn’t have a built in pump so make sure the end of the hose is lower than the outlet so gravity can do its job.
The auto defrost function makes it ideal to use in basements that experience really cold temperatures. This unit is a great option if you're looking for a garage dehumidifier as well.
If you’re looking for a 50 Pint dehumidifier then this is the best option for the price. It is effective in a space of up to 3,000 square feet and will remove 50 Pints of water a day.
If your basement experiences temperatures close to freezing then the auto-defrost function that it comes with will kick in. This unit supports continuous drain operation. Simply connect a hose to the outlet and have the other end empty outside or in a drain.
The electronic panel makes it pretty easy to set your desired humidity. Even if you experience a power failure it will start up automatically once power is restored and will remember your settings.
This is a very effective unit and is perfect for basement spaces. While most dehumidifiers in this class support continuous drain this product goes one better.
This unit has a built-in drain pump. That means that you can have the outlet hose empty into a sink or through a hole that is up to 15 feet higher than the unit.
Basements can get pretty cold but this unit will operate in temperatures down to 41 degrees due to its auto defrost function. The electronic panel makes it easy to adjust the setpoints and it will also show the current temperature and humidity.
DeLonghi have built up a reputation for making good quality appliances and this one is no different. It comes fully loaded with auto defrost, auto restart and a built-in drain pump. This means that it will continue functioning even when it gets really cold in the basement.
It also has an auto restart function so you can also rest assured that after a power failure it will start up again by itself with all your settings in place.
This unit comes with a built in drain pump which will pump away the water up to a height of about 10 feet so there’s no need to have to rely on gravity. They’ve also done a great job on making the fan and compressor really quiet so you won’t even know that it’s there.
Basements in general can get pretty cold but if yours regularly gets close to freezing then a compressor type dehumidifier just won’t be effective. You’ll need a desiccant dehumidifier and this is one of the best.
Don’t be fooled by the fact that it’s a 15 Pint unit. When it gets really cold it will outperform any of the units in the list above. It’s nice and compact so it’s easy to move around to particularly damp spots in your basement.
Desiccant dehumidifiers tend warm the space up a bit which can be an added bonus. Because it has no compressor this product is also extremely quiet.
If you’re looking for a top rated dehumidifier for basement areas then grab one of the ones we reviewed above. Ideally you want to try and keep the humidity in your basement between 40% and 50%. Any higher than this and you run the risk of creating an environment where mold can start to grow. To be able to do this effectively you need to be sure to buy the right product.
For most basements the units above will be more than sufficient. If you need a dehumidifier for large basement areas or have experienced flooding or severe water damage then an industrial type might be needed. To be able to work out the optimum dehumidifier size for basement spaces you can read our dehumidifier sizing page.
Pay attention to whether or not the unit comes with a built in drainage pump. If you have a drain that is lower than the outlet of the unit then you don't need one. If you're hoping to run the hose into a basin or up through a window then you're going to need one with a built in pump to counter gravity.
Don’t ignore the temperature factor either. When choosing a dehumidifier basement temperatures are an important consideration. If your basement isn’t heated and experiences temperatures close to freezing then there’s no point getting a compressor type dehumidifier. Even with the auto defrost function it will just sit there with the compressor off for most of the time. Even when it eventually does come on it won’t be effective when temperatures go below about 45 degrees. In that case you’re going to need to get a desiccant dehumidifier.
Whatever you choose, make sure you don’t put this purchase off. Choosing a good dehumidifier for basement spaces can end up saving you a lot of money. You may not see the inside of your basement very often but this is where a lot of home repair problems start. When high humidity and damp set in, expensive home repairs are soon to follow. It can even lead to unhealthy conditions that could make the home unfit to live in. Stop mold and mildew in its tracks by installing the best basement dehumidifier.
