Things to Consider
There are many unique features that are important to take into consideration when looking to purchase a dehumidifier. With so many options on the market, it can be difficult to determine what makes for a good choice. Thankfully, in our buying guide below, we outline all the important features to look for, as well as provide some examples. Ready to learn more? Let’s get started.
Main advantages of low-temperature dehumidifiers
There are many advantages to using a low-temperature dehumidifier. However, the main advantage of this product is that it is able to be used in cooler temperatures. While most people imagine humidifiers are used in warm and humid places, there is often a need to reduce the humidity of places that are wet and cold. In these instances, a low-temperature dehumidifier will be sure to do the trick as they were manufactured specifically to operate in these rather unusual settings.
One of the best parts about low-temperature dehumidifiers is that while they were designed to only be used in cooler areas, they still offer all the benefits of a “regular” humidifier. The low-temperature dehumidifiers will still reduce the amount of allergens such as dust, mold, and mildew in the home.
How to pick the best low-temperature dehumidifier
There are quite a few factors to take into account when looking to purchase a low-temperature dehumidifier. How big is the area that you are looking to place the dehumidifier in? This will determine the coverage area you will want the dehumidifier to offer. Other factors that are important to take into consideration include the size and weight, the machine’s noise level as well as its design and controls. These factors are all important as you will want to ensure that the dehumidifier is durable as well as easy to use.
When looking to purchase a dehumidifier, it is important to understand how far the machine will cover. To determine what you will be looking for to cover all of the space in your desired room effectively, you will need to take some measurements.
Firstly, you will need to measure the length and width of the floor. Once you have determined these measurements, multiply the two numbers together, and you will have the square space of your room.
Be sure to keep the coverage area in mind when looking at potential dehumidifiers and make sure that all machines you are checking will be able to cover your room’s measurements.
A great example of a unit that can cover a lot of space is the Vremi 4,500 Sq. Ft. Dehumidifier, which can also be used for 3,000 sq. ft. rooms or even smaller.
The performance is another factor that is important to think of. A dehumidifier’s performance refers to the rate in which the machine effectively removes the excess moisture from the air. Oftentimes, the amount of water the dehumidifier can remove from the air is in direct correlation with the coverage area offered by the machine. For example, the larger the dehumidifier performance rate is, the larger the coverage area will be. The COLZER 70 Pint Dehumidifier is a good example of this, given that it has a performance of 70 pints a day and has a coverage area of 4,000 sq feet. While there are a few exceptions to this rule, this generally is the case.
When choosing a low-temperature dehumidifier model, it is important to think about the water tank of the machine. One of the essential features of the water tank to note is its max capacity. This is especially important to look at in regards to the performance rate that we mentioned. If the capacity of a water tank is 7 pints but has a performance rate of 35 pints, the user will need to empty the water tank about 5 times a day when there is a good amount of humidity in the air. While this is not necessarily a make or break feature, it is important to think about as it will influence the ease of use. If you are looking for a dehumidifier that you can turn on and walk away from without needing to empty the water tank throughout the day, consider looking for a model that features a larger water tank or continuous drainage, such as seen with the Ivation 4,500 Sq Ft Energy Star Dehumidifier.
Size and weight
The size and weight are the two most important factors that should be taken into consideration when looking to purchase a low-temperature dehumidifier. Size is essential to keep in mind as you will need to plan for the humidifier to sit in the room that you want to remove the excess moisture from. After all, you won’t want to get a humidifier that takes up the majority of the room! Weight is also a crucial factor, especially if you are planning to move the humidifier between rooms in the house. A great example of a lightweight appliance is the Whynter Energy Star 30 Pint Portable Dehumidifier.
You won’t want the humidifier to be exceptionally heavy, as it will make it much more difficult to move the unit from room to room.
The noise level is another concern that many potential buyers have. When using the dehumidifier in the evenings or even all day long, it is extremely irritating to have a machine loudly humming in the background. Thankfully many low-temperature dehumidifier manufacturers took this concern into consideration when designing their product. Now nearly every low-temperature dehumidifier that is featured on the market, including the hOmeLabs 4,500 Sq. Ft Energy Star Dehumidifier, is extremely quiet and practically undetectable. However, if you would like some more insight into the sound levels of a specific machine, checking the various customer reviews should give you more information about the specifics of the particular model.
Design and controls
The design and control panel of a dehumidifier are also crucial to take a look at, especially if you are looking for a machine that is simple to use. At the most basic level, it is important that the settings on the dehumidifier are clearly marked and easy to read.
Some dehumidifier models have control settings that work with a timer, making for easier, hassle-free use as the machine does all the work for you! Taking the ease of use even further, some low-temperature humidifier models have a remote control function, which enables you to operate the machine from anywhere in your house.
The warranty offered by each low-temperature dehumidifier’s manufacturer is important to look into. It is especially crucial to make a note of how long each warranty lasts for. A warranty ensures that each product is fully functional as well as durable. On the off chance that a part of the dehumidifier is malfunctioning or something in the machine breaks, the product’s warranty ensures that each and every problem will be fixed, and the buyer will have a pristine and fully functional unit once again. The Frigidaire 50-Pint FAD504DWD is a great example of the appliance that has a generous warranty with 1 year on the unit and 2-5 years on the sealed systems.
Brands and prices
Brands, as well as prices, are two factors that you should consider when looking to purchase a low-temperature dehumidifier. There is a huge variety of dehumidifiers on the market, so it is wise to see a wide selection of models. Also, because there are so many options available, each buyer is sure to find a dehumidifier that fits in their budget.
The TOSOT 1,500 Sq. Ft. 30 Pint Dehumidifier is on the inexpensive side, running at about $175. On the other side of things, a premium low-temperature unit is the LG High Efficiency PuriCare Black 70-Pint Dehumidifier, which can be found at $300. If you are looking for a dehumidifier model that is in the middle of those two choices, we have eight other highly rated products for you to consider.
It is no secret that low-temperature dehumidifiers work best in cooler climates. It is commonly said that these machines function best in conditions about 65 degrees or less. However, the lowest temperature that a machine can handle is about 41 degrees Fahrenheit. It is important to note that the lower the temperature is, the less effective the machine works at removing water from the air.
Yes! It is safe to use a dehumidifier for the whole day. However, you must monitor when you need to drain the water from the tank. This is mainly dependent on the water tank size. The larger the water tank, the less frequently you will need to empty the collected water. Without knowing the specific measurements of any dehumidifier machine, it is safe to say that the water tank should be emptied at least once or twice a day.
It is important to clean your dehumidifier frequently as the machine can create a build-up if not maintained properly. To clean the water tank, be sure to frequently empty the collected water as well as clean it with soap and water about every other week. To clean the grills often found on the front of a dehumidifier machine, you can use a vacuum cleaner as the best option to remove the dust build-up.
At the top of our list, we have the hOmeLabs 4,500 Sq. Ft Energy Star Dehumidifier. This fantastic model comes with a 2-year warranty, is extremely quiet during use, and includes an automatic shut-off feature.

Last but not least, the LG High Efficiency PuriCare Black 70-Pint Dehumidifier is our premium choice here. A 1-year warranty, 2 different speeds as well as a timer make it a very great option. With all this included, it is easy to see why this model is featured on our list of the best low-temperature dehumidifiers.
