Best Humidifiers For Large Rooms Buying Guide

Choosing the best humidifiers for large rooms need not be hard at all. After all, there are so many of them in the market.

You just have to note a few very important things before you buy one.

If you need to humidify a space that is larger than 400 square feet, get a humidifier for large rooms. Small and compact desktop varieties may not be so good for you.

Why do you need a humidifier?

If you live in an area that experiences really cold winters, or one that experiences a dry climate, you will definitely need to buy a humidifier.

After all, a humidifier injects moisture into the indoor air. It can do this by spraying mist into the room, which makes the air humid.

Most of the common types of humidifiers, that is, ultrasonic, cool mist, and warm mist humidifiers, operate this way.

However, there is another way: using an evaporative humidifier. With this one, it pulls the dry air from the room into the humidifier.

This air then passes through a wet wick, and it is then dispersed into the room. That is how evaporative humidifiers work.

Whatever the case, everyone needs a humidifier for their home. It makes the air more breathable and the living conditions more comfortable.

Besides, a humidifier may also help alleviate the symptoms of pollen, dust mites, and other allergies. All you need to do is ensure that you keep your indoor humidity at a maximum of 50 percent.

You can buy a good humidifier for a large room on Amazon.com. However, also remember that ultrasonic humidifiers are notorious for causing white dust.

Best humidifiers for large rooms: A buying guide

There are so many brands of the best humidifiers for large rooms on the market. Some are portable, some are large, and some are even installed in the HVAC system.

For a large room, you will need a large humidifier. Usually, when you buy one online, you will find out what space it is rated for. Bigger is better, but it will also be costlier.

If you don’t choose a humidifier rated for the square area that you want to humidify, you will be disappointed. When you buy a humidifier rated for a small space, you will never have enough humidity.

If the humidifier is rated for a larger area than the room that you want to humidify, it may end up over-humidifying the room.

Excess humidity is not good at all. It can lead to the formation of mold. It can also allow indoor allergens, such as dust mites, to thrive.

Since the area of coverage for humidifiers is measured in square feet, you must know the size of the large room that you want to humidify. This is not too hard. You can estimate or take a tape measure and find out.

In any case, it is much better to overestimate than to underestimate. It would be better to buy a humidifier that is rated for a larger room than a smaller one.

Consider the mist output: Best ultrasonic humidifier

It is not a secret that some models produce the most mist. For the best humidifiers for large rooms, you will need one that expels a lot of mist.

For a large room, consider getting an ultrasonic humidifier as your first option. It can do a good job of producing all the mist that you need without causing a racket. It is quiet and effective.

The good thing is that we have cool mist ultrasonic humidifiers as well as warm mist ones. To enjoy the benefits of a warm mist humidifier, you can buy an ultrasonic variety. You can read my article here to see how ultrasonic humidifiers work.

Here are certain benefits that you will enjoy from your ultrasonic humidifier for large rooms:

  • It is quiet; you can run it through the night and sleep soundly at the same time
  • Produces a lot of mist in a large room.
  • With minimal maintenance, it will last a long time
  • No replacing parts such as wicks and filters. It just has a diaphragm that vibrates at ultrasonic vibrations
  • Most of them are cool mist so they are safer in kids’ rooms since there is no steam involved
  • They are energy-efficient, so you do not have to worry about your bill spiking

Consider buying an evaporative humidifier

When it comes to mist output, the evaporative humidifier is only second to the ultrasonic one.

With this kind of humidifier, you can say no to dry indoor air in your house. Because of its ability to produce a lot of mist, this humidifier is really efficient for large rooms.

There is a bit of controversy over the information regarding evaporative humidifiers. Some people just refer to them as warm mist humidifiers (I will tell you why shortly).

Some people just refer to them as just that: evaporative. So, why do some people call them warm mist humidifiers?

The reason is that this humidifier boils the water in the tank. The water turns into vapor, which is then dispersed into the room.

Thus, instead of droplets such as those you get with the ultrasonic humidifier, the evaporative humidifier sends water vapor. This hangs on the air longer than water droplets can.

In some places, evaporative humidifiers are also called steam humidifiers because that is basically what they do: produce steam. So whether you get one or the other, you are getting the same thing.

Such humidifiers are going to consume more electricity than cool mist ones or even ultrasonic humidifiers. However, it is nothing to worry about since the results more than compensate for that.

Do the best humidifiers for large rooms need to be big?

Many people think that the size of a humidifier matters a lot, and, to some extent, it does. For example, you cannot use a small bottle humidifier for a whole room.

However, most of the time, the size does not matter that much, that is, as long as you get a reasonably-sized humidifier. Consider the model more than you would consider the size.

At the same time, you should read the description of the humidifier. If you are buying one on Amazon.com, this should be easy, as buyers also leave their reviews. That way, you will know what the humidifier capacity is rated for.

Most people worry that a big humidifier will be noisier. Again, this is not correct because the noise level of a humidifier depends on the model.

A big ultrasonic humidifier such as the Proscenic 807C Ultrasonic Cool Mist Humidifier that you can buy on Amazon.com has very low, almost negligible noise levels. The capacity is big, though, as you can tell from the 5.5-liter tank.

When it comes to noise levels, well, ultrasonic humidifiers are king, again! The ultrasonic frequency vibrations are so low as to be negligible.

It does not matter how large it is, because as long as it is an ultrasonic one, it will suffice even for baby’s room.

If you want to humidify a medium-sized room, the warm mist humidifiers come in handy. There is a small setback, though, because most of them cannot humidify a large room. It is much better to go for a cool mist ultrasonic humidifier.

Consider ease of cleaning of large room humidifiers

The best humidifiers for large rooms are easy to maintain. Since humidifiers are about water, it is easy for them to breed bacteria, mold, and viruses.

If you let it get to that, these disease-causing agents will be dispersed with the mist, and you will inhale them.

The only way to keep your humidifier mold- and germ-free is by cleaning it. Mostly, you clean the tank, the wick, and the filters if you are using cool mist or warm mist humidifiers.

You need to access the humidifier parts that need cleaning. It should be easy work to take everything apart and put it back together.

If you are using a warm mist humidifier, you will not need to clean it as often as someone who has a cool mist humidifier. The boiling water kills the bacteria.

For a cool mist or ultrasonic humidifier, you will need to clean it a few times a week; some even do it just once. You would need to use a water and vinegar solution for cleaning the tank, then rinse it thoroughly with clean water.

Usually, every humidifier comes with cleaning instructions from the manufacturer. Always read the user manual before you can crank it up.

The price of the humidifier

We always say that you should not sacrifice quality on the altar of money. It is better to pay more and get more features than to pay less and get fewer features.

Thankfully, the best humidifiers do not cost too much. Well, the most extravagant ones can go up to $1000, perhaps more, but the features are well worth the price. At best, humidifiers can cost anywhere from $10 to $500.

The best humidifiers for large rooms may cost more than the smaller ones. Just ensure that the humidifier has enough features for the price. It is not the cost that matters; it is the value that you will get from the item.

Consider the warranty too. 12 months or more of warranty is a good confidence booster.

Automated features of the best humidifiers for large rooms

The best humidifier should have good features. The more automated features it has, the better! Since a humidifier for a large room means it can give more mist, if left unmitigated, the damage could be quite extensive.

Humidistat

Image of a humidistatAt the very least, always buy a humidifier with a humidistat. The humidifier switches itself off automatically when the desired humidity level is achieved.

Without this feature, the humidifier would raise your indoor humidity higher than you need, to destructive levels.

Built-in timer

This is another important feature. Some humidifiers even come with a timer that can be controlled through a smartphone app.

With a timer, you can set the time when you want the humidifier to start releasing mist. That way, you will find your room already well-humidified by the time you get home.

Some humidifiers also have a remote control for programming them. Some can be programmed through an app. You can also program the humidifier for large rooms so that it shuts down once the water in the tank is finished.

Aromatherapy feature

Sometimes, you need something extra to increase the humidity in the room. Just consider buying a humidifier with aromatherapy function.

You will be able to add essential oils to the container integrated into the humidifier for just that. That way, when the mist rolls out, it has a touch of a nice aroma to it, making the indoor air feel fresh.

It may not feel as pure as it would if you had an air purifier for your home, but it will be good.

User-friendliness of a humidifier for large room

No matter how many features a humidifier has, if it is not user-friendly, then it is not very good. Using one should be a straightforward matter—filling it with water, cleaning the tank, and so on.

If it needs programming, that too should be very simple. You do not want to have to keep referring to the manual or check Google for information about how to start it, stop it, and so on.

The best humidifiers for large rooms should be easy to use, clean, and store. Luckily, manufacturers are integrating more features into simple designs, so you should have a pretty easy time using one.
