What To Look For When Selecting A Dehumidifier

There are few main factors you should take into account when you’re looking to invest in a dehumidifier for your home.

1. Capacity

One of the most important aspects to consider before you buy a dehumidifier is the capacity.

If you have larger rooms in your home that have issues with high levels of moisture in the air, then you should look at dehumidifiers with more capacity in their containers. This will make things easier for you, and will prevent the need to constantly replace the container throughout the day.

70-pint is the largest dehumidifier we cover in this guide, which is capable of extracting up to 70 pints of moisture from the air. There are also 50-pint models which are suitable for most rooms, and then compact units which are ideal for the smallest of rooms.

2. Features

While dehumidifiers are only going to have a single purpose to remove moisture from the air, there are some useful features that a few models have.

The features won’t necessarily add functionality, but can make the experience of using them easier and can provide you more information on what your dehumidifier is doing.

For example, our top pick in this guide the Ivation 50-pint has a user-friendly LCD interface which displays a variety of helpful information such as a humidity meter. It also lets you set timers to suit your lifestyle and automate the process.

3. Noise Level

If you live with others, or plan to use a dehumidifier through the night, then you should bear the noise level in mind.

If it’s especially loud, you might find it disturbing which is the last thing you want. A lot of dehumidifiers will make a constant humming sound so finding one that is silent is a difficult task, but you can definitely find quieter models.

4. Energy Efficiency

Something which could save you a lot of money is investing in a dehumidifier which consumes a low amount of energy. Of course, you can’t help the fact that it will need to be on for a long period of time and will cost you money, but you can choose energy-saving options.

Some, like the Ivation 50-pint dehumidifier also feature technology which allows them to automatically switch off and restart to save wasting energy needlessly.

Frequently Asked Questions About Dehumidifiers

Do dehumidifiers help with mold?

Dehumidifiers can be a great way to help clear up mold, mildew, and dust mites.

The reason why dehumidifiers can be an effective tool to fight mold since the common household growth thrives in humidity. Mold tends to grow in humid environments like the basement and the kitchen, but having a dehumidifier in the room can stifle the growth.

They can also be used as a preventative measure, to ensure that mold is less likely to grow in your home. This makes them excellent for dealing with both potential and current issues with mold growth.

How do I get rid of mold in my dehumidifier?

If you don’t empty the water container of your dehumidifier on a regular basis, there’s a chance that it can develop mold.

In order to deal with mold buildup in your dehumidifier it’s best to slip on some rubber gloves and first empty out the water in the container into a sink or drain.

You can then create a solution of water and dish soap in the water container. Swirl this around to ensure you remove any remaining mold. 

Lastly, to deal the killing blow to any muld that’s settled on the inside of the water container, you can add a mixture of bleach and water. Let it rest for around 20 minutes, and then rinse out the water container one last time.

This should take care of any mold residing in the container, so you can start using your dehumidifier again.

What brand of dehumidifier is best?

It’s hard to pick out a single dehumidifier brand as the best, but there are some excellent options out there.

Ivation, Frigidaire, and Danby are all popular dehumidifier brands for various reasons. There’s also Pro Breeze and Eva-Dry which both have excellent portable dehumidifiers which are best suited for small spaces and rooms.

We especially like Ivation though, and we selected their 50-pint model as the best dehumidifier for tackling mold. What we like about it is its compact size and impressive performance. It can cover spaces up to 3000 square feet, and features an intuitive LCD interface for greater ease of use.

Where is the best place to put a dehumidifier?

As a general rule, you should try to put a dehumidifier in the room of the house that has the highest level of humidity for the best results.

This tends to be either the bathroom, the kitchen, or the basement in most cases, since water collects in all three of them.

However, it’s also usually the case that humidity is worse upstairs than downstairs. This means that if your home has more than one floor, you’ll have to decide between putting it in one of the most commonly affected rooms which are usually on the ground floor, or upstairs.

Another factor to bear in mind is the temperature of different rooms, and floors. If the top floor is colder, then that would be the better choice. Likewise, if the basement is especially cold, then that would be a great place to put it.

If you have a few rooms together which produce a lot of moisture in the air, namely kitchens, bathrooms, and laundry rooms, then one of those rooms would greatly benefit from a dehumidifier.

You should try to take all of these factors into consideration when deciding where to place a dehumidifier, but it also depends on your personal situation. If there is already mold in one room then of course you should put it there.

The great thing with dehumidifiers is that they’re easy enough to move around should you need to keep several rooms under control.

Do dehumidifiers really work?

Put simply – yes. Dehumidifiers do a great job of drawing excess moisture out of the air, which helps prevent such problems as mold growth and damp.

The question should be less about whether or not they work, and more about the right time to use one.

If your home is already showing heavy signs of mold or damp growth on the walls or ceiling, then it’s time to invest in a dehumidifier.

However, if you just notice signs of condensation and moisture, then there’s a chance you can deal with this before it becomes a major issue with extractor fans, smart sealing of cracks, or simply wiping down wetness whenever you notice it.

A Final Word on Dehumidifiers and Mold

Dehumidifiers can be very effective for addressing problems with mold and allergies at home. Hopefully this guide has shown you the different things to look out for to know which dehumidifier will be best for your home.

Especially if you’re in a cold climate and have a lot of moisture in the air, you could live a lot more comfortably with a dehumidifier.
