Dyson AM10 is a stylish model with a stylish ring design and clean water tank.

Amazon reviews give Dyson AM10 an average score of 4.2 (out of 5), but 70% of them are five-star reviews. Positive reviews commented on how effective UV is at killing bacteria in the water and how easy it is to use. Negative reviews point out that the machine is quite complicated to set up and clean, while others comment on how small the water tank is, which means you have to add water more frequently than other humidifiers.

 It can be used as both a humidifier and a fan. It has 10 floors and looks great in any office or living space. With some powerful features, you can set it to sleep mode, while the automatic mode allows you to choose the humidity level you like. However, it is one of the most expensive models on the market, and its water tank is relatively small-only 3.75 quarts.

One of the great advantages of this Dyson humidifier is that before the water evaporates, it will purify the water-using ultraviolet rays to remove bacteria and minerals. This is one of its best qualities, especially for those who worry about the air quality at home. It is easy to replenish water. You can use it continuously for 12 hours before you need to rehydrate. This model is more suitable for smaller rooms under 172 square feet.

There is only one button on the actual model, and the humidifier is controlled by the remote control, allowing you to change the fan and humidity level. The humidity level can be set between 30% and 70%. However, this humidifier is also designed to adjust the temperature you want and will change according to the temperature in the room. This Dyson humidifier is a good investment product, especially when it doubles as a fan, which means it will not sleep in the summer. 

This humidifier is perfect for large rooms because it has a large water tank that can hold up to three gallons of water. 

Reviews on the Honeywell HEV685W humidifier on Amazon rated the model 4.4 out of 5, most of which were given 4 or 5 stars. Satisfied customers commented on its effectiveness in humidifying the room-up to 50%, while others expressed how easy it is to humidify and multi-fan speeds. Negative comments are about the ease and noise of changing the filter. 

However, it is a loud and bulky model, so it is not suitable for an office or sleeping environment. This humidifier has a fairly basic design and has fewer features than competitors in this price range.

This model is easy to install, with two easy-to-install flat propellers and two water tanks. As an evaporative humidifier, this model sucks in dry air from the room through a wet filter, and then draws out warmer air to change the humidity of the room. If you are looking for a high-tech humidifier, then you might want to look elsewhere because this model has only two buttons to control its humidity and fan speed. The fan speed can be fast, medium or low, which is also its quiet setting. Without an LED screen, being able to actually set the humidity level you are after can be confusing.

This humidifier performs well, with a maximum humidity of 63% and a minimum humidity of 53%. Since both of its water tanks are large, it can also run continuously for 24 hours at the lowest setting, and then needs to be refilled again. 

The Levoit LV600HH humidifier has some interesting features, including three atomization settings, essential oil diffuser for aromatherapy, and dual nozzles that can rotate 360 ​​degrees. 

Customers on Amazon gave the Levoit LV600HH humidifier an average score of 4.5 points (out of 5), and they mentioned humidity levels and remote controls the most. Positive reviews say that the mist output is high and easy to clean, while negative reviews mention how warm mist can become very hot and how inaccurate the automatic settings are.

As a smaller model, it is very quiet but can hold a lot of water, which means it can run for up to 36 hours. 

This humidifier is perfect for larger rooms between 430 and 753 square feet. The built-in water tank is transparent, which means you always know how much water is left in the tank. Being able to sit on your workbench or hide under the table is a bit tricky to fill it up. However, this humidifier can be used as soon as it is out of the box, and no other settings are required except for adding water.

There is a small LCD display on the front, as well as various buttons that allow you to control the haze, humidity and operating time of the humidifier. The atomization function has three settings from low to high, and the humidity button allows you to change the percentage of humidity in the air. At the same time, the beautiful remote control means you can control the humidifier from 16 feet away. Useful is that this humidifier is easy to operate and very quiet.

This is a small and attractive model with touch screen buttons and a large display that shows temperature and humidity levels. 

Elechomes HTJ-2119 ultrasonic humidifier performed very well on Amazon, with a score of 4.5 (out of 5). Many people like the smoothness of the humidifier and the very low noise. Other positive comments like how it is controlled via the remote control and how easy it is to set a specific humidity level. Negative comments focused on how small the handles of the models were, and some people said that the lights on the models distracted them at night.

The humidifier emits cold mist, and the built-in humidity sensor allows you to set the humidity level you prefer. Other features include child lock, sleep mode and the option of adding essential oils.

This model is stylish but tall, so if you want to tuck it into a corner or under furniture, you need to be about a foot high. Filling the water tank is fairly easy, and it performs best in a medium-sized room or house or anywhere equal to 322 to 528 square feet. The buttons on the display are easy to use and clear at a glance, and the remote control can also control the humidifier. 

The highest fog setting can increase the humidity level of a medium-sized room to 69% within an hour, and the humidity target can be adjusted so that you will not feel uncomfortable with the humidity level of the room. However, please be careful not to leak water at the highest setting-our reviewer found a leaking pool during testing. Fragrance pads are also a good choice, allowing you to add essential oils to the pads, and then the humidifier will emit with the mist to bring extra fragrance to the air. 

The only smart humidifier on our list, the Levoit Classic 300S humidifier, is connected to the VeSync app, which allows you to control the haze and notify you when it needs cleaning. 

Amazon's review of the Levoit Classic 300S humidifier received an impressive 4.6 points (out of 5), and many satisfied customers commented on how quiet it is and how easy it is to clean because of the large opening on the top of the humidifier. Negative comments focused on how the humidifier is too sensitive and the automatic mode is not as easy to use as other models.

Medium-sized and fashionable model, the clean water tank is located on the top, so you can clearly know the remaining water volume.

Very suitable for small and medium-sized rooms, the humidifier requires some assembly, but it is not a complicated matter. With a large LED display, it can clearly indicate the humidity level, and the buttons for haze, night mode and humidity level are located around this. The connection app is easy to download and connect via WiFi. After downloading, the app allows you to switch between manual, automatic and sleep modes. You can also set a timer and change the humidity level through the app.

This humidifier is easy to clean, and its humidity level performs well in both high and medium fog settings, rising to a level of 68% within two hours at the highest setting. Another quiet model, it lasts 19 hours at high settings, but 60 hours at lower settings. However, the built-in humidity sensor is very sensitive, and the model does need to be cleaned regularly to prevent bacteria from entering the water. 

The best humidifiers are a great investment for your home, but like many basic equipment, they require aftertreatment to keep them in top operating condition. The representative of the Environmental Protection Agency Tim Carroll gave Live Science advice on how to maintain the humidifier: 

• Empty the water tank every day, dry all surfaces, and add water to the portable humidifier to reduce the growth of microorganisms.

• Use water with low mineral content to prevent mineral accumulation and reduce the possibility of mineral diffusion into the air.

• Clean the portable humidifier every three days.

• When storing the product or not using it frequently, clean and dry the humidifier thoroughly.

• Do not humidify until the relative humidity level in the room exceeds 50%.

• Do not let the area around the humidifier get wet or damp.

• Follow any specific manufacturing instructions for use, cleaning, and maintenance.
