What To Look For In A Dehumidifier

While most dehumidifiers are built to meet the most basic standards at the very least, some of the better ones stand out not only through their dehumidifying capabilities but also to fight mold and a variety of other humidity-related issues. the best thing about it – modern dehumidifiers neither have high operational costs nor are they difficult to look after maintenance-wise.

Even so, you are advised to take the time and figure out precisely what your needs are and what exactly you expect a dehumidifier to do for you. To give you some pointers, we put together a short guide that deals with the pros and cons of modern dehumidifiers in order to provide you with a clear perspective on what’s out there.

Perhaps the most important thing you want to consider when buying a dehumidifier is the coverage area. This is because each particular dehumidifier is designed to cover a specific area at maximum efficiency, so you need to think long and hard about the part of your house in which you will set up the device.

You can, of course, get a whole house dehumidifier if you’re planning on getting a dehumidifier for the whole family, but these devices are usually rather expensive and difficult to maintain. If you get one for your basement, for example, you need to make sure that whatever device you purchase can meet the space demands of your actual basement.

Whether you get a small dehumidifier or a large one, you want to take the time and consider the overall performance of the device and how it translates to your particular needs. When we talk about a dehumidifier’s performance we talk about the numerical variable used to represent the amount of moisture that a dehumidifying device can reduce over a specific period of time.

As such, you want a device that meets not only your necessities but also one that can be operated safely and inexpensively. For instance, basements are commonly humid by nature, so any device used to dehumidify the air inside a basement should be highly potent and able to work without human intervention.

You also want to think about a dehumidifier’s pumping power, mainly in regards to the physical pump many of these devices incorporate. A decent dehumidifier usually features an inbuilt pump that can push out a specific quantity of water over a specific period of time. In fact, a dehumidifier with pump should be considered a must-have by anyone who spends a lot of time away from home.

These types of machines are preferable to classic designs on account of clearing out the water themselves without needing any human intervention whatsoever. This way, you don’t have to keep going back to clear the water inside the tank every time it fills up.

Tank Capacity
A good dehumidifier should not only incorporate a water tank at this point in time but a fairly large one as well. Now, the point of a water tank is to store any collected moisture so that it can be easily disposed of at a later time. As we said, some dehumidifiers feature a pumping system that doesn’t involve a tank. These devices are usually less common than those with inbuilt water tanks, not to mention how much more expensive they are.

Depending on the size of the room you want to place the dehumidifier in, you might find it easier to simply get yourself a device with a decently sized water tank. Then again, the selection process usually leads to devices that meet certain functional parameters, meaning that form rarely has anything to do with it.

Whether you get yourself a cheap dehumidifier or decide to invest in a high-end model, you will definitely want a model that meets most of the basic industry standards. Given the sheer selection available at this point in time, you may have to do a fairly bit of research before finding one that not only delivers performance-wise but one that can also function according to preset parameters.

For instance, good dehumidifiers can perform at various speeds and can be used to serve a more versatile purpose. This is precisely what you want to consider before making a purchase because you won’t always use your dehumidifier at full capacity.

There are a few dehumidifiers out there that possess the capacity to drain the water continuously rather than store it in a tank somewhere. Needless to say, these dehumidifiers are quite rare and they are commonly bulky in size.

It isn’t that they do not have a water tank, because they do; it’s just that they also incorporate a drainage hole at the bottom of the tank for the water to pour away once the tank has reached a certain capacity. Alternatively, you can improvise a drainage system for any dehumidifier you might have as long as they meet all the structural requirements.

One should also consider the size of any dehumidifier they purchase, especially if they plan on setting it up in rooms with a limited amount of available space. As such, you might want to consider a portable dehumidifier for your household if you want to move the device around the house over time.

Although small dehumidifiers are much more accommodating in that regard, high-end models are usually bulkier in size and require a thorough installation process; albeit, with a much higher output than regular-sized dehumidifiers.

For instance, you might want also want to consider getting a crawl space dehumidifier to aid with your crawl space dehumidifying needs. As we said, it usually comes down to the size of each individual unit when determining where exactly to position them inside the house.

You should also try your best to get a dehumidifier with a long warranty, especially if you get a particularly expensive model. If you, for instance, acquire an energy star dehumidifier for your house, basement, or garage, then you also want to ensure that the device packs a fairly lengthy warranty. We say this because the more expensive a household appliance unit, the more it costs to repair it if it ever breaks down.

Your best choice in this regard is to get a unit made by a reputable manufacturer as they commonly offer the longest warranties by far. Another thing to consider is that a bathroom dehumidifier is bound to have a shorter warranty than one that people set up inside regular rooms.

Price Tag
Even though your primary concern should be the functional parameters of whatever unit you plan on buying, you certainly want a device that’s relatively cheap. Bear in mind that the more complex a dehumidifier is the more expensive you can expect it to be.

If you can, do a little research beforehand by checking online reviews so as to determine if the unit you want to buy meets the standards you expect. If you’re happy with what a certain dehumidifier has to offer, the price tag should be the least of your concerns given how durable most of these devices are.

Features To Look For

Despite the fact that most dehumidifiers meet specific standards towards the high-end part of the price spectrum, some definitely stand out more than others performance-wise. Some even incorporate complex features that may or may not be related to most people’s dehumidifying requirements. If you know what’s good for you, you will emphasize performance over virtually any other feature, function, or capability. Then again, people tend to have a very subjective view of what constitutes a good performance.

LED Indicators – In this day and age, you definitely want household appliances to boast some sort of display or user-friendly interface. It just so happens that decent dehumidifiers commonly incorporate LED/LCD displays that showcase all the functioning tasks and parameters of the device at any given time. While LCD displays are more compact and easy to access, LED displays are usually more visible in low-light conditions. It should also be said that with a wall mounted dehumidifier or similar, you rarely have full access to the device, thus the need for perfect visibility via its display.

Auto Shut-Off – This feature is more and more prevalent in household appliances nowadays and understandably so. Not only are devices that come equipped with auto shut-off functions more efficient overall, but they also provide a higher security standard. With dehumidifiers, you have to understand that sometimes the weather outside makes it so that the humidity levels inside the house are quite tame. When that happens, you don’t really want your dehumidifiers operating at full capacity, not if you want to avoid a large electric bill.

Defrosting – It needs to be said that some dehumidifiers underperform in cold weather conditions or refuse to function altogether. A decent dehumidifier, however, should incorporate an auto defrost module to prevent the machine from freezing up if left unattended. This is especially useful for people who rely on an under house dehumidifier to rid them of mold and mildew. So if your basement gets a little too cold during the winter, then perhaps you should consider investing in a dehumidifier with a defrosting capacity if you haven’t already.

Types Of Dehumidifiers

Heat Pump Dehumidifiers – These types of dehumidifiers make use of fans, heat pumps, and heat exchange coils to remove moisture from the air. As such, they are usually inflexible and require that you set them up in a deliberate way and never move them around. Performance-wise, these dehumidifiers can be expected to perform reasonably well in medium to small rooms on account of their practical design. It should be said that garage dehumidifiers fall into this category along with crawl space dehumidifiers and any limited-range dehumidifier out there.

Chemical Absorbent Dehumidifiers – Sometimes referred to as ‘desiccant dehumidifiers’, these devices consist of hydrophilic materials like silica gel. When operational, they employ single-use desiccant cartridges, gel, or powder to remove the humidity from the air around them. Needless to say, these humidifiers are quite intricate in their design, which also means that they come with a price tag to match. Not just that but they are also quite rare considering how peculiar they are not just in terms of performance but through their aesthetics as well. You will find that car dehumidifiers are sometimes built according to chemical absorbent principles and that they behave in a very practical way.

Whole-House Dehumidifiers – These practical systems act by monitoring the house according to a preset level of acceptable humidity. For this reason, these dehumidifiers are usually set up to turn themselves on whenever certain parameters have been met in order to not only protect your health and that of your family members but also to protect the furniture and any electric/electronic devices you might own. It should also be said that this type of dehumidifier also requires regular maintenance and end up costing more than basic models in the long run.

Homemade Dehumidifiers – There are indeed people out there who prefer to build their very own dehumidifiers. Although we strongly advise against such practices, you need to be made aware of their existence at the very least. Now, we do not recommend these dehumidifiers as a permanent solution for your humidity problems but it’s certainly something to consider if you possess the technical know-how and you have the will and ambition to actually build up such a system.


Whatever your perspective on dehumidifiers, you need to take your time deciding which unit to buy and where exactly to set it up inside the house. You need, for instance, to get yourself a quiet dehumidifier for your bedroom or the children’s room, whereas garage and basement dehumidifiers are allowed a little bit of extra noise. In the end, it usually comes down to personal choice more than anything, especially in this day and age in which most modern devices share a wide range of functional parameters they all try to adhere to.
