The Vornado Evap40 evaporative humidifier is an effective way to add extra moisture into the air in your home. It utilizes a unique vortex system of air circulation to boost humidity rapidly and evenly throughout the room. Rather than the typical circulation used by evaporative coolers, this vortex system speeds up the circulation of the air to all corners of the space. With this method, the Evap40 can humidify an impressive 1,000 square feet.
At the highest speed, the 4-gallon tank will run out in 24 hours, but if a lower setting is used the humidifer can last much longer. With such efficiency, it reduces the number of refills required making your life a little easier.
Although there is no digital display, the dials for setting the humidity level and fan speeds are easy to use and very intuitive. You can set the level of humidity you desire, and the unit will shut off once that level is reached.
The humidifier itself is well built and has an eye-catching and unique design. You can immediately tell that this model will stand up to a lot of use and the manufacturer backs their product with a 5-year warranty.
While this is not the most functional unit on the market, for the price and size of the humidifier, the area it can humidify is quite impressive.

Tank Capacity: 3.5 gallons

On the display panel, you can also specify your desired humidity level. Once this is reached, the unit will shut itself off, conserving energy and water in the storage tank.
Made in the USA this high-quality large capacity humidifier is the perfect choice for increasing the moisture throughout your whole house or large living areas. If you only need to humidify a small space such as a bedroom, then this large unit is probably overkill.

Weight: 8.9 pounds
Dimensions: 12.2 x 18.9 x 8.1

Where the EVDC500 differs from other models is its focus on energy efficiency thanks to the energy smart DC motor and smart energy saving mode. The manufacturer claims that this model uses 90% less energy compared to a Vornado AC motor-driven humidifier.
With the smart energy saving mode, which is activated by the push of a button, the unit can stay operational but draw as little as 1 watt to keep you comfortable. The humidifier will also shut off when the target humidity is reached and when the water tanks are empty.
The next best feature on this unit is the easy to fill water tanks. While other humidifiers make the refilling process a real chore, the EVDC500 makes this process seamless.
Two separate 1-gallon tanks are on each side of the humidifier and can be taken off for refilling. The large openings on these tanks make refilling and cleaning a breeze.
With a 5-year overall warranty and a 10-year warranty on the electric motor, you can rest assured that this humidifier will last the distance.
Coverage Area: 700 square feet
Tank Capacity: 1.5 gallons

Dimensions: 10.2 x 18.8 x 9.1 inches

This model also utilizes the unique vortex action to circulate the humidified air through the room. The fan has two speeds that you can alternate between as needed along with auto-humidity control to achieve and maintain your ideal humidity level.
On the highest setting, the EV200 will consume approximately 2.6 gallons per 24 hours. However, on lower settings, this consumption can be reduced.
When it is time to refill, the designers have tried to make the process as painless as possible. This unit uses the same two tank design as other more expensive units in the range.
These tanks can be removed and refilled using the large openings. Many users also appreciate the access these large openings give for cleaning the interior of the reservoirs.
Like other humidifiers in this range, the company offers a lengthy 5-year warranty. This highlights the company's commitment to quality and their unwavering faith in the sturdiness of their products.

You can cycle through the humidity settings and different fan speeds using the control panel on the front of the humidifier. With the adjustable humidistat, you can set your desired humidity level, and the unit will automatically maintain it and shut itself off once the set humidity level is met.
Regarding build quality, this is a sturdy unit. It is built in the USA using quality parts and materials, so you can trust it to keep on working for years to come.
While this may be a great unit if you are looking to humidify your whole home, it may be a bit too heavy duty if you only want to use it in a single room.
What Is the Recommended Level of Humidity Inside Your Home?
The Environmental Protection Agency (EPA) has done comprehensive research on the topic and concluded that indoor humidity levels should be kept below 60% and ideally between 30-50% at home.
The more advanced humidifiers have a built-in humidistat which you can use to set your preferred humidity level in your room. It is also a good idea to have a hygrometer as a backup to give you accurate readings of the relative humidity. Click here to see our guide on the best hygrometers to use with your humidifier.
How to Choose the Right Type of Humidifier for a Big Room
There are many different types of humidifiers, and they all have unique pros and cons, which can make choosing the right model for a large room difficult. Every manufacturer also makes big promises, but it can be hard to figure out whether the humidifier will suit your specific needs.
To help you make the right choice, we are going to look at the different types of humidifiers that are available. The following information will help you to understand how they work and which one is best for you.
1. Ultrasonic Humidifiers
Ultrasonic humidifiers are the latest in humidifier technology and can be an excellent choice if you want a model with minimal noise. They work in a way that sounds complicated but is actually quite simple.
Ultrasonic humidifiers create a visible mist by using a high frequency to send vibrations through the water. As the water vibrates, water droplets form, which are then distributed through the room, increasing the moisture in the air.
The main benefit of these units is that they do not need noisy fans to operate. Not only does this save electricity, but it also makes them super quiet which is perfect for use in bedrooms at night.
Some users experience problems with white dust when using ultrasonic humidifiers. This residue is a result of the minerals in tap water that are left behind after the mist lands on furniture or others surfaces and dries up.
While the residue is not harmful to most people, it could potentially be problematic for people with asthma or other lung/sinus health conditions. The only real solution to prevent white dust is to use distilled water instead of hard water.
Large ultrasonic humidifiers are a good option, especially when noise needs to be kept to a minimum. However, they are more suited to medium to large-sized bedrooms rather than large living areas or the whole house.
2. Evaporative Humidifiers
Evaporative humidifiers are by far the most common type of humidifier amongst the large-sized models. This type of humidifier has been around for a long time and can be particularly useful for larger rooms.
Evaporative humidifiers rely on both a fan, a wick filter and a water reservoir to operate.
The wicks, which are made of a permeable material, pull water up from the storage reservoir. The fan blows dry air into the moist wick, causing the water to evaporate. The purified mist is then circulated around the room, increasing the humidity level.
With this effective and simple system, you can get guaranteed results very quickly, but there are some disadvantages as well.
First of all, the fan can be quite loud on some units, mainly when the highest setting is used. This can disturb your sleep if you wish to keep the humidifier running overnight. In addition to this, the wick filter needs to be replaced approximately every 4-8 weeks which incurs an extra cost and can prove to be an annoying chore.
Despite these negatives, the vast majority of big humidifiers are evaporative as the powerful fan makes them very efficient at humidifying spacious areas. If you are looking to humidify a large living area or even your whole house at a fast pace, then an evaporative humidifier is the best option for you.
3. Whole House Furnace Humidifiers (AKA In-Duct or HVAC Humidifier)
Many people, especially those building new homes or doing extensive renovations are having whole house humidifiers fitted. These humidifiers are installed as a part of the heating/HVAC system and deliver moist air alongside the home's heating or cooling.
These systems can be quite effective and have the benefit of being unobtrusive. However, there are some key reasons why we do not recommend going down this path.
The most significant disadvantages to these systems is that they are expensive and limited by the existing ducting in your home. While the air near the ducts will be humidified, other areas of the room can miss out. At least with portable ultrasonic or evaporative humidifiers, you can move the unit to where it is needed the most.
You will also need to consider the cost of having a furnace humidifier installed by a professional. It is definitely not a cheap option, and the ongoing maintenance can hurt your back pocket.
Warm Mist vs. Cool Mist Humidifier for a Large Room
Warm mist humidifiers work by heating water into steam. The entire process is not only very inefficient, but it can also be unsafe for children.
With hot steam and heating coils, it is possible for children or even adults to be burnt. In fact, the American Academy of Pediatrics (AAP) recommends against the use of warm mist humidifiers in homes with children.
Despite this, some people do like the warmth that the steam gives. At the end of the day though, the risks and extra costs aren’t worth this small difference as they are no better or worse than humidifying a room compared to an evaporative or cool mist ultrasonic model.
Our top product recommendation, the Levoit LV600HH is a hybrid model that can produce warm and cool mist at levels that can be easily adjusted, giving you the best of both worlds if you desire a warm mist model.
Choosing Your Humidifier Based on Room Size
Now that you have an idea of the best large humidifiers on the market, you face the challenge of selecting the correct one for the size of your house or a particular room. Unless you get a unit suitable for the size of the area you want to humidify, you may be disappointed with the results.
Before even looking at a humidifier, get an approximate measurement of how many square feet your room is. Then when choosing a model, you can compare your measurements to the capacity of the unit.
As you will have seen in the reviews above, we have listed the coverage area for each recommended unit. These are the guidelines given by the manufacturer. They’ll give you a good indication of what size room the humidifier is best for.
Once you have chosen a suitable humidifier, you need to then look at things such as efficiency, noise level, and portability. There is almost always some kind of trade-off when making this choice.
For example, the most powerful console units are noisy and heavy due to their evaporative cooling process and large water reservoirs, but portable devices can lack the power for large spaces. At the end of the day, only you can decide which humidifier will suit your needs.
The frequency of refilling is also something to consider. The more portable the unit is, the more often you usually need to refill it which can be a bit of a chore. If you plan to run the humidifier for long extended periods, then you may want to look at a larger model that is less portable but has a big water reservoir.
If you need a humidifier for a smaller area, particularly bedrooms, then you should get an ultrasonic humidifier. While they're not as powerful as an evaporative humidifier—the advantage is that they make very little noise which allows you to have an undisturbed sleep through the whole night.
What to Look for When Buying a Large Humidifier
In addition to the considerations outlined above, we have put together a brief list of other important features to look for. As long as you do your research now before you make a purchase, you are guaranteed to be happy with the humidifier you end up choosing.
Ease of Use
First of all, you want a humidifier that is easy to operate. This includes being easy to change settings, move around, clean and refill. The controls should be user-friendly—look for a model with a digital display and remote control for the best experience, such as our top pick the Levoit LV600HH. If you want an evaporative humidifier, then ensure that the wick filter is straightforward and inexpensive to replace.
One of the biggest complaints people have about evaporative humidifiers, in particular, is the noise they generate. To help you control this, you should look for humidifiers where you can adjust the intensity of the fans and subsequently the noise level. A humidifier with multiple fan speeds will also help you to increase the humidity across a larger area rapidly when required.
Another useful feature that you should look for is a timer. A lot of people like to set a timer overnight so that the humidifier runs for a fixed period as they’re sleeping and then shuts itself off automatically.
Humidistats are pretty much a necessity in a modern humidifier. They allow you to set a target humidity level and then the humidifier will automatically shut down or activate as needed to maintain that level.
Waterless Automatic Shut-Off
Choosing a model with waterless automatic shut-off is a great way to ensure maximum efficiency. This function detects when the tank is empty and shuts the unit off, saving electricity and preventing unnecessary wear and tear on the humidifier.
We rated the Levoit LV600HH the best large area humidifier on the market because it has all of these important features and many more.
Why Is Cleaning and Maintaining Your Humidifier so Important?
Before you rush out and buy a humidifier, it's important to understand that you will need to regularly clean it to see the full benefits and to prevent any health hazards. If it is not frequently cleaned, a humidifier can become a breeding ground for mold and bacteria. The EPA recommends cleaning humidifiers every third day.
Although evaporative models can be very effective, they also require a bit of extra maintenance. The wick filters in the evaporative models need to be replaced approximately every 4-8 weeks to keep the humidifier working efficiently. Many factors affect the life of the wick, including the amount of use and water hardness. You’ll know when it needs to be replaced when the filter becomes hard and is no longer absorbing water properly.
We also recommend using a Bacteriostatic Water Treatment which is specifically designed for evaporative models to prevent the growth of bacteria and algae in the filtration system. This treatment will eliminate any unpleasant odors and maximize your humidifiers effectiveness.
If you choose an ultrasonic model, it is recommended to use distilled water in the tank. Tap water can have a higher mineral content (hard water) and can leave a white residue (white dust) around the area where your humidifier is being used.
Below, we will outline how you should clean a humidifier.
How to Clean Your Humidifier
Firstly, make sure to turn your humidifier off and unplug it from the wall outlet before starting any cleaning maintenance.
Draining, rinsing and changing the water in the tank before each use is ideal to help eliminate any bacteria that may have started to grow inside the container. Periodically, the tank will need to be wiped down and cleaned with mild detergent and water to remove any buildup of impurities.
Preferably twice a week you should do a deep clean of the base. For this, you can use a diluted vinegar solution to clean the unit and remove any mineral deposits. Then use a diluted chlorine bleach solution to disinfect the humidifier which will prevent any bacteria and mold growth that may occur.
Ultimately, you should follow the manufacturer’s instructions for the humidifier you have purchased.
Frequently Asked Questions
Q: Where Should a Humidifier Be Placed in a Room?
A: When you position your humidifier in a room, remember that the area closest to your humidifier will be affected the most. Ensure that it is placed at least 1 foot away from all walls, furniture, curtains, and electrical appliances and ensure the mist nozzle is pointing towards the center of the room to avoid any water damage.
We recommend elevating ultrasonic humidifiers at least 2 feet off the ground on a desktop or nightstand with a water-resistant tray underneath your unit. This height gives the mist from the humidifier enough time to evaporate in the air before it reaches the ground. If you are using an evaporative humidifier, you can place it on the floor, but we also recommend using a water-resistant tray underneath just in case of a spillage.
Do not place your humidifier on or close to wooden surfaces or carpet where water damage could occur without protection. Always use a flat surface to keep the humidifier level and avoid any heated or warm surfaces such as on top of a furnace.

Q: Is It Safe to Leave a Humidifier on All Night?
A: It is safe to sleep with a humidifier on all night provided you keep the humidifier clean, and you don’t over-humidify the room.
To avoid any health issues, change the water before each use and wipe down the inside of your humidifier regularly. Cleaning your humidifier should be done ideally twice a week with a mixture of white vinegar and water.
Also be wary of white dust, which is a buildup of mineral deposits from tap water that is left behind when the mist from an ultrasonic humidifier settles on surfaces. To prevent white dust, use distilled water that does not contain any mineral content.
The National Sleep Foundation suggests that the ideal humidity level in your bedroom is between 30% to 50%. Remember to monitor the humidity with a hygrometer and maintain an appropriate humidity level. We recommend using an ultrasonic humidifier with a built-in humidistat. The humidistat will shut the unit off when the desired humidity level is reached to prevent any chance of over-humidification.
Q: Does a Humidifier Help Congestion and a Cough?
A: If the air in your home is overly dry, a humidifier can help alleviate coughing and sinus congestion by adding moisture to the air. The increase in moisture can loosen the mucus and open your air passageways.
Remember to keep the humidifier clean. Otherwise, bacteria and mold can grow in the tank and be released into the room through the mist, potentially causing health problems ranging from flu-like symptoms to serious infection.
Q: What Kind of Water Do You Put in a Humidifier?
A: If you have an ultrasonic humidifier, using distilled or demineralized water instead of tap water eliminates the risk of white dust from the unit being spread into the air and breathed into your lungs.
If you have an evaporative humidifier, the type of water you use in your unit will depend on where you live. Tap water will suffice for many owners. However, if your tap water is particularly hard, it is better to use filtered water to prolong the lifespan of your wick filter.
Which Large Capacity Humidifier Is the Best Choice for Your Home?
Overly dry air inside your home can impact your family’s quality of life. Especially when using heating systems in the winter, the air inside your home can be rapidly stripped of moisture causing several annoying problems—ranging from irritated sinuses to nosebleeds to itchy eyes and long sleepless nights. Fortunately, a humidifier is a simple solution that accurately increases the moisture in the air to combat this age-old problem.
If you have large rooms or a large home with open plan living, you may think it is impossible to humidify the air effectively, but you would be wrong. As you will have seen in the above reviews, there are many models on the market suitable for use in large homes. It is true that some units are substandard and are hard to keep clean, but if you choose the right product by following our recommendations, you will be amazed at how quickly and easily a humidifier can work.
