The 10 Best Single-Room Humidifiers
1. PureGuardian H940 Cool Mist Humidifier – Best Overall
Our best overall choice is the PureGuardian Ultrasonic Cool Mist Humidifier because it can provide up to 30 hours of runtime on one tank. The .5 gallon tank is of a small enough size to fill it easily. The humidifier has three speed settings, so you can choose which is best for your room. It provides up to 4L of moisture output per day, which is enough for even a dry climate. You can change the direction of the mist nozzle to point it toward you while you’re sleeping. It also has a refill-indicator light and automatic shut-off when empty, so you don’t have to worry about it overheating when it runs out of water. To prevent mold and bacteria growth, it has silver-clean technology in the tank.
Because of its slim design, this humidifier is difficult to clean. Certain cleaning products also cannot be used on the tank because of its silver-clean technology.
2. Pure Enrichment Mist Humidifier – Best Value
The Pure Enrichment Cool Mist Humidifier is the best single-room humidifier for the money because of its slim, compact design. It’ll fit anywhere in your house and has a high or low mist setting, so you can choose how much humidity you’d like in the air. It can deliver up to 60 ml/hr on low and up to 80 ml/hr on high, and it has a 10-hour runtime on one tank. The tank holds 0.7L, which contributes to its slim design. Because the tank is small, it’s easy to fill. The humidifier is also completely silent as it releases a cool mist.
This particular humidifier doesn’t have a directional mist nozzle, so you can’t point it toward you — the mist only goes straight up into the air. It also doesn’t have any special coating on the tank or UV light to inhibit mold growth, so you’ll have to clean it frequently.
3. LEVOIT Dual 100 Humidifiers – Premium Choice
If you also like to diffuse essential oils, this two-in-one humidifier is a great option. It has a sleep mode that turns off all display lights, so it won’t wake you or a baby in the night. It has a design that’s easy to clean and fill because you can take it apart. The water tank holds 8 liters, which gives it a runtime of eight to 20 hours, depending on which mist setting you have it on — either high, medium, and low — so you can choose the best one for your needs. It uses Spiral Air-Duct technology to create a fine mist that won’t damage furniture. It also has an auto shut-off feature to prevent overheating.
Even though this is our premium choice, it doesn’t have a special coating or UV light to inhibit mold growth. It should not be used on floors, towels, carpets, or any surface with fibers that may block the air inlet.
4. TaoTronics Cool Mist Humidifiers
The TaoTronics Cool Mist Humidifier has a space-saving design with a 1.8L water tank. With the dual-knob control, you can choose how much moisture to be released into the air. It also has an adjustable mist for 360-degree humidification, which allows you to move the nozzle to the perfect setting. It has a smart LED indicator, so you can see at a glance if the humidifier needs more water. It’s ultra-quiet and BPA-free, so it’s suitable for use in a bedroom or baby’s nursery.
Because of the slim design, this humidifier is tricky to clean. It’s especially difficult to get to the water tank. The humidifier is all white, including the water tank, so you can’t tell at a glance how much water is left.
5. MADETEC Cool Mist Humidifier
The MADETEC Cool Mist Humidifier is another option that allows you to diffuse essential oils. It has a rotating, removable nozzle that allows you to easily adjust the mist’s direction. There are three mist modes: low, high, and cloud, which is where you simply remove the nozzle. It includes a remote control, which is especially handy when you want to turn it on at night. It has a water tank capacity of 1L, so it can run for 20 hours on low and 11 on high. To prevent overheating, it has an automatic shut-off when it’s low on water.
It doesn’t seem to produce enough mist to fill a room, even on high. It also leaks water, so you have to be careful where you put it. The remote control is the only way to turn it on and off — there are no buttons on the actual machine — and it’s difficult to use.
6. warrita Cactus Humidifier
The warrita Cactus Humidifier has an ultrasonic operation to keep it whisper-quiet. This is a compact humidifier with only a 160ml water tank. It’s meant to be kept in a small place, like a bedroom or office. It has a fun novelty cactus design and includes different colorful lights. After four hours of running, it will turn off automatically. It also has an auto-shutoff feature when the water tank is low. This is one of the most inexpensive options on our list.
It has an extremely small capacity, so you’ll be refilling it often. Because of this, it has a short runtime and won’t last all night. There’s also no way to adjust the speed of the mist.
7. Homasy Cool Mist Humidifier
The Homasy Cool Mist Humidifier is another option for an essential oil diffuser. It has a 2.5L water tank capacity, and you can refill the tank from the top, making it easy to use. It has a runtime of up to 30 hours, which allows you to run it for two or three nights without having to refill the tank. It comes with three mist modes: high, low, and sleep. It’s quiet at only 28 dB, which is around the decibel level of a whisper.
However, after a few days of use, the humidifier becomes much noisier. Because of this, it can be difficult to sleep with it on at night. There doesn’t seem to be enough mist, even on high mist mode. It also tends to leak, so you should be careful what you place the humidifier on.
8. iTvanila C1A Humidifiers
The iTvanila Humidifier releases cool mist and has a 2.7L water tank capacity. This gives it a runtime of 12-28 hours, depending on the mist flow you choose. It has a 360-degree rotatable nozzle to change the direction of the mist flow. It has a whisper-quiet operation so you can run it at night without being bothered. It comes with an automatic shutoff when it’s low on water, and an indicator light tells you when you need to add more.
Unfortunately, the runtime isn’t as long as it states. This might be because the water leaks and the mister seems inefficient. There’s always a pool of water around this humidifier. It’s also difficult to empty and clean.
9. AICOOK QLS-06 Humidifiers
The AICOOK Humidifier has a large 3.5L water tank capacity, which allows it to run for 12-36 hours. This is great if you want a humidifier that you don’t have to fill constantly. It has a 360-degree rotatable nozzle so you can adjust the mist to your liking. It’s BPA-free, so it’s safe for use in a baby nursery. When the humidifier runs low on water, it automatically shuts off.
The light is bright, however, and there’s no way to turn it off, which might be problematic if you want to run it at night. The mist falls instead of shooting into the air, which causes water to pool around the humidifier. The tank is also difficult to refill and leaks.
10. YINGJEE Mini Humidifier
This is another cactus-shaped humidifier with a small, 340ml water tank capacity. It fits easily on a nightstand or a desk. It can also be used as a night light. Despite its small capacity, it can run for eight to 12 hours at a time while connected to a USB port.
This humidifier doesn’t hold a charge well. It’ll only run for a minute or two if it’s not plugged in. The nozzle also clogs easily, so you’ll have to clean it often. It doesn’t produce much mist, and water tends to pool around the humidifier. It can also quit working after only a few uses.
There are many features to keep in mind when shopping for a single-room humidifier. To make it easier, we’ve created a buyer’s guide to help you in your search.
Many humidifiers come with a built-in humidistat that allows you to set your desired humidity level. Once the humidifier detects that that level has been reached, it’ll shut off automatically. This makes things easier because you won’t have to monitor it closely. It also prevents the room from getting excessively humid and foggy.
Because single-room humidifiers are all portable, the size will depend upon runtime. If you want it to be light and portable, then a smaller water tank will be better. If you want it to last 30 hours or more, then a tank that’s at least 6 liters is best.
Water Tank Design
If you’ll be using the humidifier regularly, then it’s important to look for a water tank design that’s easy to use. A water tank that’s too tall, for example, might make it impossible to fill with your sink’s faucet. You also want a water tank that isn’t difficult to remove.
Auto-shutoff features can both make your life easier and prevent your appliance from burning out. With this feature, the humidifier will turn off when it runs out of water. If you plan to run the humidifier all the time, this prevents you from having to monitor it closely.
Humidifiers can quickly make you sick if harmful mold and bacteria are allowed to grow inside them. Certain humidifiers can be difficult to clean, which endangers your health. Those that have a UV light are especially helpful because they eliminate any microbes that may be growing inside the tank. This way, they aren’t released into the air along with the mist.
If you have hard water and don’t want to use distilled or bottled water in your humidifier, then a demineralization cartridge can extend the life of your appliance. It collects the minerals from the hard water that not only can collect inside the humidifier but also be released into the air.
Certain humidifiers come with filters that can trap irritants from the air like pollen, dander, and dust. For people with allergies, this can help prevent the humidifier from becoming another irritant.
Our best overall choice is the PureGuardian H940 Ultrasonic Cool Mist Humidifier because of its 30-hour runtime on one tank. The tank inhibits mold and bacteria growth with silver-clean technology. It has three speed settings and quietly releases a cool mist.
Our best value choice is the Pure Enrichment PEHUMSML Cool Mist Humidifier because its slim, compact design allows you to put it on even the smallest nightstand. The tank is only 0.7L, so you can refill it easily. It has a 10-hour runtime.
We hope our reviews and buyer’s guide have helped you narrow down your own list and find the best single-room humidifier to meet your needs.
