The Best And Most Popular Dehumidifier Features

If you have high humidity levels or a big moisture control problem in your home, then you are probably going to want to purchase a dehumidifier. Not just anyone will do, however. You want the best dehumidifier for your money. If that is the case, then this article was written just for you. That’s because we are going to talk about the features you need to look for when choosing one of these units.

I have spent a considerable amount of time reviewing and testing dehumidifiers. I have seen really good models with all of the features a person could want and I have seen models that I wouldn’t buy at a garage sale. So many in fact, that I can now tell a great unit from an average unit just by taking a quick look at the features it has. Yes, just by casually checking out the features in dehumidifier reviews I can tell if a unit is worth buying or not. Information that I am now going to share with you today. Below you will find a list of features that can be found on some of the best units on the market today. Find a unit that has the majority of these features, and you will most likely find out it is one of the best.

40-70 Pint Capacity

I have found that the best capacity for most homes is around the 40-70 pint capacity range.  That’s big enough to deal with most humidity problems that can be found in the home. Of course, if the dehumidifier is going to be used in an industrial or commercial capacity, then this pint range would be too low. But for the average home it is perfect.

Auto Shutoff

If your dehumidifier uses a reservoir collection system, then you are going to want to make sure that it has an automatic shutoff system as well. All this feature does is turn off the unit when the reservoir capacity has been reached. This not only protects the unit but also keeps it from making a big mess.

Electronic Controls

While I don’t have any particular aversion to manual control systems on a dehumidifier, I do think that electronic controls are the way to go. Not only do they make the machine easier to use, but they often allow you to to zero in on your preferred humidity range a lot better.


A humidistat is another feature found on the more popular dehumidifiers. This features shuts off the machine when the preferred humidity level is reached and turns it back on when the humidity is beginning to get high again.

Caster Wheels

If you’ve ever had to move one of the bigger dehumidifiers around the house, then you know why this feature made this list. Having caster wheels on the device just makes it that much easier to move it from room to room. Which is a big plus if you have multiple rooms in your house with humidity problems and need to service these rooms in sequence.

Essential Dehumidifier Features

While one person’s definition of the best dehumidifier will differ from another person’s definition, I think it is probably safe to say that there are probably some features that should be common to all high quality dehumidifiers. Essential features that will ensure that the dehumidifier not only performs the job it is designed to do, but will do it without needing a whole lot of user input. Today, we are going to talk about some of these essential features of dehumidifiers and why they are important for you to consider before purchasing one.

The Water Reservoir

This feature can be found on most dehumidifiers. I am saying most because some use units don’t use a reservoir but either have a continuous drainage feature or uses some form of water absorbing material, such as silica gel, to collect water. We will talk about some of those a little bit later.

Dehumidifiers have reservoirs to collect the water that drip from the condensing coils when the moisture is extracted from the air. Therefore, you really can consider it as being an essential part of the whole dehumidifier. When buying a dehumidifier, it is important to get a dehumidifier with a decent size reservoir because you don’t want to have to empty it out more often than you really have to.

Continuous Drainage And Condensate Pumps

You will find continuous drainage on systems that don’t use a reservoir system, and its basic operation is fairly simple. What a continuous drainage system does is send the water down a hose so that it can exit the system via a floor or sink drain. As water is collected form the air, it is sent to the exit hose where gravity does its thing and carries it away from the unit.

Some dehumidifiers with a continuous drainage system also have a condensate pump that isn’t gravity based. Which means that it can pump the water upwards away from the system. This allows the drainage hose to be put into a sink drain or through a basement window.

Automatic Defrost

If you look through dehumidifier reviews, then you’ll notice that a lot of dehumidifiers have an automatic defrost feature. All this feature does is to defrost the condensing coils if they freeze up because of lower than standard room temperatures. This allows the unit to be used in cooler environments—such as basements—that often fall below 42 degrees.


A humidistat is an essential feature in my opinion because it allows you to fine tune the humidity levels in your room. Units that don’t have one usually have to either run all of the time, or the user has to manually turn them on and off to keep humidity levels in their preferred range. Units that have a humidistat will automatically shut off when they have reached the minimum humidity level and turn back on when the humidity level gets too high. All without user input.

The above features are the ones that I consider essential on any dehumidifier. They not only allow the unit to operate more efficiently and effectively, but they also reduce the amount of time that you have to dedicate to setup and operation of the unit.
