Best Humidifier Dehumidifier Combos: A Buyer’s Guide

The Benefits of Getting a Humidifier Dehumidifier Combo

So, why not just get a humidifier or a dehumidifier on its own? Well, there are actually a number of benefits of getting a unit that combines the two.

It’s incredibly important to ensure that you have a balanced amount of humidity in your home. It’s important to avoid lots of moisture in the air, but overly dry conditions can also be problematic. 

Your air quality will be stellar throughout the whole year with a humidifier dehumidifier combo, and you won’t even need to spend extra money on getting two separate devices! It also means that you only have one device taking up storage space instead of two of them. 

Things to Look For

Level of Humidity

If you reside in a place that has a colder climate, using a humidifier is a good choice because there will be a lot of dry air. On the other hand, if you live in a warmer climate or somewhere that’s more humid, then a dehumidifier is a better choice because it can help to reduce the amount of extra water vapor or humidity present.

This means you need to worry less about allergies and corrosion that caused by mold and mildew. You should ultimately think about the weather conditions where you live and make a decision based on this. Ideally getting a dehumidifier and humidifier combination is the best option. 

Amount of Space 

It’s always important to think about the amount of area that you need to cover as every humidifier or dehumidifier has a particular size where they are able to function their best.

Always check if the unit is able to cover the amount of space that you need to treat. On the subject of space, however, you should also think about how much physical space you have, as some of these units can get pretty large.  


When you are looking for a dehumidifier humidifier you should always try and get an option that comes with a humidistat. These devices will show you whether you need to run the unit or not depending on the level of humidity. This means you can save on energy and optimize the amount of time that the unit is operating.

Usable Control Settings 

Your device is designed to maintain the correct amount of moisture in the air, so it should not be difficult to set it to actually do just that. Always opt for a machine that offers you easy controls so you aren’t spending ages trying to figure out how things work. 

Auto Shutoff

You find that a lot of dehumidifiers come with a reservoir container and this stores all of the water that the unit has collected.

The unit isn’t going to be able to handle too much water, so of course if the device continues to run when it’s full then it means that water will spill all over the floor – this essentially makes the whole device pointless because you’ve just put the water back into the atmosphere.

Having a device with an auto shutoff feature when it’s full is thus rather important, especially if you don’t want to have to keep checking every five minutes to see whether it’s full or not. 

Large Capacity 

Humidifiers and dehumidifiers require water reservoirs in order to function properly. If you are using the dehumidifier function, the reservoir is where the extracted water is store until you are able to empty it. Alternatively with a humidifier, the reservoir is where the water is stored before it is put into the air. Naturally, whatever option you’re currently using, a large capacity is definitely helpful.  

If you’re trying to dehumidify the whole house, it is important that you get a big storage bucket so there’s no need to empty out the water. For a humidifier, you don’t want to be refilling it every single day. For the sake of convenience, look for an option with a large capacity. 

Noise Levels 

It’s important that your unit doesn’t make too much noise, especially if you’ve put it in a bedroom. Who wants to hear their unit roaring at them all through the night? Check the dB rating of the device to see how noisy it is. Alternatively, you can also check other buyer reviews to see if it makes a lot of noise. 

Frequently Asked Questions 

Should you operate a dehumidifier and an air conditioner at once? 

It’s possible to run both at once, but if you need more dehumidification with more power, then you should operate the dehumidifier alone.  

Is a dehumidifier or an air conditioner better? 

It largely depends on what you need. A dehumidifier is designed to get rid of lots of dampness without causing the temperature to drop. On the other hand, having a system that controls the climate is going to help decrease the amount of moistness and it’s going to lower the temperature. In this case, you are better off using dehumidifiers in situations where you aren’t concerned about cooling but moistness is a problem.

Where is the best place to put a humidifier dehumidifier combo?

There are a bunch of different locations where you can put one of these units. Generally it depends on what your air is like in that specific location and what kinds of results you are expecting. Dry air usually becomes an issue during the winter, so in that case you will want to put the device in the location where you spend the most time during the winter. Bedrooms and living spaces are an example of this. 

If you are looking to dehumidify a room’s air, then it’s worth putting the machine somewhere that tends to have a lot of problems with damp and moisture. This is usually in the basement. This is because basements are usually wet and damp, and water can seep in through pipes or the foundations.

If you do have this issue, you should always keep the dehumidifier in the basement or downstairs in general in order to stop any mold and mildew, or other problems that may arise as a result of humidity. 

You could also keep the unit in the kitchen or the bathroom, areas that are especially wet and are more likely to get moldy. This can also help to improve the general air quality of the home. 

What are the main problems of low and high humidity?

High Humidity 

High humidity can often result in mold forming in the home. Not only this, but you may be more likely to get insects in your home if you have high humidity. A lot of these insects can eat mold, so you may be more likely to have insects such as cockroaches or mold beetles invading your home.

Humidity can also have a nasty affect on your woodwork or furniture. Things like paint and wallpaper can start to peel, and wood can begin to warp. You can also get all sorts of health problems and allergies as a result of mold growth in the home. 

Low Humidity

Low humidity can be just as much of an issue as high humidity can be. It can result in health problems, in addition to issues in your home. As far as health is concerned, low humidity can result in things like skin problems, issues with the respiratory system and can actually cause irritation in the eyes.

In fact, after prolonged contact with dry conditions, your skin can become flaky, dry and issue. It can even result in things like skin diseases, like eczema, psoriasis and skin allergies. 

There are even some people that experience respiratory problems. This is because your lungs and throat can become irritated when exposed to dry air consistently, and this can also make it rather difficult to breathe. 

Low humidity can also cause a plethora of problems in the home too. If you have air that is too dry, issues can arise such as warped or cracked wood on the floors, and the glue and caulk in the joints of the house can end up weakening. You’re also more likely to get issues with static electricity.
