Coming across a sudden rise in humidity around the home is an experience that no one should go through. From degradation of wooden surfaces to the rapid spread of moulds and as a result their spores in large rooms, excessive humidity drags a lot of unhealthy living conditions along with itself and is only modified by the best dehumidifier for large room.
Humidity might be much easier to control in small-sized rooms, but in larger areas, you would need far more powerful products, than the regular dehumidifiers. The best large room dehumidifier should be able to pull a large amount of moisture from all corners of the room, and nothing less. Anything short of this would result in very poor dehumidification.
Depending on your peculiar situation, running the best dehumidifier for a large apartment or the best dehumidifier for a big room might just cut it. Keep in mind, however, that the dehumidifiers for the large apartment must be of more capacity than the one for just a big room.

What type of dehumidifier will dehumidify a large room effectively?
Speaking from experience that most large room are residential apartment, a dehumidifier that is designed to cover up to 4000sqft would suffice. There aren’t many single rooms out there larger than 4000sqft, and for the ones that actually are, they mostly make use of whole-house dehumidification, and not exactly portable dehumidifiers.
However, some Portable dehumidifiers rated up to 9000sqft (Dehumidifier for Large rooms) and would work well in large rooms since bigger is always better. But you are better off installing a whole-house dehumidification system for extremely large-sized rooms, which is more effective than portable units.

Top 5 best dehumidifier for large room
The different dehumidifiers on our review list would be discussed according to four categories; capacity, automatic features, ease of use/ noise level, and other features. Also note that all the products here come with the safety 20 seconds to 3 minutes time duration when powered on and off, to protect the compressor. Immediate shutting off can cause damage, and the delay time varies depending on the manufacturer.
1) Ivation 70 Pint Energy Star Dehumidifier
This dehumidifier is out rightly built for high-end purposes, precisely large room dehumidification. For this reason, the product is designed and built with high fan capacity for drawing in the air per minute, as well as sufficient enough compressor for the moisture removal process.
Its overall dehumidification system is able to remove an impressive amount of moisture from the air, up to 50 pints in a day according to the new department of energy standards.
This high moisture removal is backed up by a fan and compressor power that is able to dehumidify up to 4,500sqft area. The dehumidifier does indeed, remove a high amount of moisture when tested, and it is why the 1.3galon water tank was put in place, for sufficient backup.
For more convenient running, the water can be channelled through a continuous drainage passage to wherever you would rather it go to.
- Automatic features
This is a section in which the dehumidifier really comes out top amongst its peers. With every automatic feature, you can ever think of; this product has enough to practically run itself.
The first is a 24-hour timer function, allowing users to set precisely in hours, how long the device would run before shutting down. Proper use of a timer would afford users much operational flexibility of the dehumidifier, as well as intelligent power consumption. Moisture level can also be selected, after which the device is allowed to run and maintain it (auto mode).
The next automatic features to point at are the auto defrost, auto restart, and auto-shutoff. The auto defrosts monitors the coils of the compressor for ice buildups, which is common, especially under low temperatures. On detecting the presence of ice, it activates the auto defrost function, turning off the compressor and melting it off.
Having ice in the coils reduces the dehumidifier efficiency. The auto-shutoff, on the other hand, comes into play when the tank fills up. This feature causes the machine to shut off, preventing an overflow, while the auto-restart stores the preset user settings, restoring them on power outage and restoration.
- Ease of use/ noise level
The first comfort feature of this dehumidifier is in its mobility. With the unit sitting on four caster wheels, moving the dehumidifier around is very easy. It also has a digital LED user-friendly display, with soft buttons for easy controls, and understandable interface.

Examining the features as well as the actual performance of this kesnon product, it bears an exact resemblance to the previously reviewed iviation dehumidifier. It is built for the large areas, being rated for 4,500qft by the manufacture, and we must say it’s an area it can conveniently handle based on our performance tests.
This product has a very good fan, which is able to circulate the air in such large space and is responsible for its ability to dehumidify areas of up to 50 pints of moisture per day.
The dehumidifying capacity of this unit means that its water tank would fill up very quickly, and is the major reason why a 1.18 gallon of water is put in place by the manufacturer.
For those who would prefer not to cycle through the regular stress of emptying the tank every now and then, there is also an option for continuous drain, where the water is channelled directly out of the unit.
- Automatic features
The automatic skill set of this kesnos product is pretty packed too, with the presence of a timer, auto shutoff, auto defrost, and the most impressive auto mode of operation. The timer is also a 24-hour clock, which allows you to preset the entire runtime of the machine, including when startup and shut down.
The auto-shutoff, on the other hand, is a custodian of safety, monitoring the tank level and turning it off as soon as it gets filled up, while the auto defrosts ensures ice isn’t present to hinder the performance of the unit.
The most impressive feature of all is the automatic mode. After adjusting the humidity sensor to your desired moisture setting, the machine takes over from there, working on varying its fan speed in order to maintain this preset level at all times, keeping you exactly where you want to be.

Built for large area dehumidification, this product packs a good fan as well as compressor and other features to make the users’ life easy while getting the job done. It is suitable for areas up to 4000sqft in size according to the manufacturers, and we agree on; however, its 70 pints of moisture extraction per day is questionable.
On actual testing, this device extracts something closer to the 30 – 50 pints number, rather than the proclaimed 70. This is still a very high capacity and would do for a 4000sqft sized room. The tank is able to hold up to 7.4 pints of water in size, meaning you would have to empty it a couple of times in a day at high moisture environs, or better still, simply make use of the optional continuous drain connection.

According to the manufacturers, its numbers stand at 50 pints of moisture removal per day from the air, coupled with being able to work effectively in up to 4000sqft area. This puts the dehumidifier amongst the top products at least, even though those numbers might be a bit exaggerated, the square feet area especially.
It backs it’s high per day moisture extraction rate with a 1.5-gallon tank which holds a good amount of water. For more convenience, you can always turn to the continuous drain option by attaching the hose and channelling to where ever desired.
- Automatic features
The automatic features are championed by the auto-shutoff for safety first, turning off the dehumidifier to prevent an overflow of water when the tank fills up, while also freezing all button functions till the tank is emptied.
It is seconded by another rather efficiency feature in the auto defrost, kicking in every 45 minutes to get rid of ice formed in the coils to keep the unit running at maximum efficiency.
Asides those two frontiers, the auto mode is another feature that is in a league of its own. In this mode, it shuffles between off and on the state, automatically stops working when a specified humidity is reached, and restarts when higher than the target humidity. This humidity must have been previously set by the user.

5 Factors to consider in choosing the best dehumidifier for large room
The relationship between the capacity of a dehumidifier and its performance is in direct proportion. This means that the higher its pint rating, the more effective it would be in drawing moisture, as well as taking lesser time.
Keep in mind that a product is always rated by its manufacturer, indicating its maximum square footage and the capacity holds as far as it is running in the recommended footage too.
Although bigger is always better when it comes to dehumidifier capacity, for more economic reasons, however, we recommend you purchase a slightly higher square feet product than your room (100 to 200sqft more).
- Automatic features:
Automatic features adds the much-needed bliss to user experience while using a dehumidifier. The most important ones which we recommend your product should have at least are; auto shutoff, auto defrost, auto mode, and timer.
These functions both help create a safe working environment, preventing the device from overflowing with water (auto-shutoff), melting ice in the coils as they form (auto defrost), working independently to balance humidity(auto mode), and a timer to choose how long it would stay in service. In all, with all these features, using the dehumidifier would be much more convenient.
Due to possessing large compressors as well as high capacity fans for air circulation, dehumidifiers are almost certain to produce an amount of noise.
This should, however, be minimal, enough to not irritate. Purchase a product with a track record of quiet only, unless you intend locking it away to work somewhere in your basement.
- Ease of use:
Features that make a product easy to use includes a digital display with control buttons and indicators. The button’s visual appearance alone screams at users what they do. Other convenient features include wheels for mobility because dehumidifiers are pretty heavy due to having compressors, and also handles for carrying.
- Continuous drain:
This is another must-have feature in dehumidifiers for large rooms. Large room dehumidifiers have a larger tendency to accumulate water faster than the one in an average-sized room. Hence their tanks fill up faster and would require frequent emptying.
Having a continuous drain option eliminates the stress of taking out the water every now and then, and although it does not seem like much, it is basically the most user convenient feature to have in a dehumidifier.
How a big of a dehumidifier do you need for your room
Well, the size of the dehumidifier needed is determined by how large your “large room” is. From the efficiency perspective, you should get the largest size of dehumidifier that you can afford, as that would keep humidity far away from your environs, but when we look on the other side of economics, it is not exactly a wise thing to do.
At most, purchase a device that is rated to serve rooms a little larger than yours, in order to make up for any exaggeration in qualities as regarding performance. Simply measure your room size and shop products for that range accordingly.
How many pint dehumidifiers do you need for a large room?
A dehumidifier that is rated for a particular room size always comes with a minimum moisture removal rate in pints. For example, dehumidifiers with capacity up to 4000sqft, are mostly rated around 50 or 70 pints depending on the department of the metric energy system, per day.
The range of 1500sqft to 3000sqft usually remove 30 to 40 pints per day. What we are saying, in essence, is that as far as the product is recommended for your room size by its manufacturer, then it has enough pint moisture removal at least, to dehumidify your room.
You can choose to go for more performance, however, by vying for high pint products in the same class, for more effective performance, and in all you do, never go below a product that removes 40 pints of moisture per day.
Can a dehumidifier be too big for a room?
Yes, there is a possibility that the dehumidifier is too big for a room. This is characterized by having very dry air, too frequently, and in a short amount of time.
On the flip side of things; however, you could simply have a larger product for a room, but with controls that allow users to limit its capacity to fit its immediate environment. Therefore, in the real sense, a dehumidifier might be too big for a room, but works just fine, or be too big and cause too low humidity levels that are harmful to inhabitants.
