Buying Guide

Those on a budget may not be able to afford a huge, high-end dehumidifier to take care of these issues, but a smaller model that costs less than $100 is a great alternative. Though cheap, these little dehumidifiers work well in small spaces, taking up very little room while still doing a fantastic job of removing the excess moisture from your home. If you’re unsure which one is right for you, check out the sections below for more information.

Features to consider when choosing a dehumidifier under $100

5 Most Functional Dehumidifiers under $100 Only — Effective Solution at a Fraction of the Cost

When choosing the best dehumidifier for under $100, there are a few features you may want to consider. This will ensure you’re getting the right model for the space you have available and the moisture issues you’re dealing with.

Coverage area

The coverage area listed for the dehumidifier you buy is one of the most important features since this tells you the largest area the model will work well in. The smaller the coverage area, the smaller the area your dehumidifier can be used in.

For instance, the Ivation Thin and Compact Dehumidifier has a coverage area of 30 square feet, so it can be used in crawl spaces, powder rooms, closets, or other small areas that are this size or smaller. If you tried to use this model in a room that exceeds this area, it likely won’t be able to keep up, removing very little moisture out of the air since it can’t circulate the air efficiently.

For large rooms, you need a unit that can handle the space. Of course, you won’t be able to get a whole-home dehumidifier for under $100, but at this price, but you can get few small ones and place them wherever you need them the most in your home.

Capacity

The capacity of a dehumidifier tells you how much water the tank will hold before the unit shuts off or overflows. The more water it holds, the less often you need to empty it on a particularly humid day. Some of these models only hold small amounts of water, like the Pro Breeze Electric Mini Dehumidifier, which has a capacity of 16 ounces. This means that the tank isn’t very big, so on a humid day, you may be emptying it once a day or more, depending on how long you have it running.

A larger tank, like the 64-ounce reservoir on the InvisiPure Hydrowave Dehumidifier, holds more water, so you may only need to empty it every few days. Of course, the more water there is in the tank, the heavier it will be to carry to a sink or drain to empty it. Though it takes less time, it may be a more difficult task, so keep this in mind when choosing a new dehumidifier model.

Dehumidification performance

5 Most Functional Dehumidifiers under $100 Only — Effective Solution at a Fraction of the Cost

Another feature to look into when choosing a dehumidifier for under $100 is the performance. This tells you how much moisture the unit is pulling from the air over an entire day. This can vary depending on a unit, so don’t assume that one with a higher coverage area or a larger tank will work faster than a smaller, lower coverage model.

Most of the small capacity models that cost $100 or less have lower dehumidification performance than the more expensive, high-end models. The ones in our reviews range from about 10 ounces per day to almost 30 ounces per day. As well as looking into the features we’ve described above, consider the humidity in the area you live in and how efficient you want your model to be. Higher humidity may need better performance to keep moisture issues at bay.

Dimensions and weight

The dimensions of the unit tell you how much space the dehumidifier will take up in your home. Most of the cheaper models on the market are compact, but there are some differences to consider. You can choose a tower dehumidifier under $100, like the Ivation Thin and Compact Dehumidifier, which are tall and slim, so you can squeeze them onto a shelf or desk without using up too much space. There are also square-shaped or rounded models that are a little wider but are also short, so they can fit onto a nightstand or even in a corner of a bedroom or bathroom. Consider where you’d like to place your dehumidifier and buy the model that fits best with the other features you want.

You should also consider the weight of your new dehumidifier, especially if you plan on moving the little model from room to room. Luckily, all of the models in our reviews are quite light at less than 10 pounds each, so you won’t strain yourself when you shift their position now and then.

Built-in handle

Though not a common feature on these types of dehumidifiers, a few of them do have a built-in handle on the unit that makes it easy to carry it with you wherever you need it. The InvisiPure Hydrowave Dehumidifier is one of these units, with a carry handle located at the back of the unit, built right into the plastic. This gives you the perfect handhold when you are carrying your dehumidifier to a new room or from your RV to your house after a camping trip. A built-in handle makes a unit like this much more portable and easier to move when needed.

Other features

The features described above are the main ones to focus on when choosing a new dehumidifier under $100. Of course, there are some extra features you may want to consider since these will make the model you purchase much more convenient to have in your home.

One thing to look at is the controls. These should be easy to use, even if it’s your first time setting up a dehumidifier. All of the models in our reviews have a single button or switch to turn them on and off.

An auto-shutoff is also something to look for. This feature turns off the dehumidifier when the water tank reaches a certain level. This prevents the tank from overflowing, so you won’t have a mess to clean up. An indicator light is often included with the auto-shutoff, turning on or changing colors to tell you that the tank needs to be emptied. Many models also include transparent tanks or a tank window to allow you to monitor the tank level at all times.

The dehumidifier design is another feature to consider. Some of the models in our reviews have a sleek, modern look, while others are more utilitarian. They also come in varying shapes and sizes, with tanks and controls located at the front or the back. Choose the design you like best that will work well in your home.

FAQ

This depends on the amount of moisture you’re dealing with. It is a good idea to leave your dehumidifier running at all times when trying to eliminate moisture from a leak or plumbing issue or in damp or humid weather to reduce the moisture levels in your home. In drier climates or for bathrooms with low ventilation, you can turn it on when you need it and then off again instead of running it continuously.

To clean the water tank on a dehumidifier, you first need to turn off the unit and empty any water it has collected. Then fill the tank a quarter full with warm water and a few drops of dish soap. Scrub it with a sponge, getting into all the corners. Empty the tank again, then spray it with pure vinegar. Leave it for about 10 minutes, then wipe it clean with a damp cloth. Let it dry, and then replace it in the dehumidifier.

The continuous drain option allows you to attach a hose to the unit, which allows the dehumidifier to drain the water instead of collecting it in the tank. This is a great option for those who plan to use the dehumidifier constantly since you don’t have to empty the tank every day or two to keep it running. You do need a drain near the dehumidifier for the hose to drain into, like a floor drain in a basement or a sink.
