Affordable, modern, smart, and top-fill, this Levoit dual 200s humidifier is one of the best cool mist humidifiers I have tested. I am amazed that we can get such an advanced humidifier at this price range but it is only good for small to middle-sized spaces.

Why you can trust this review: I purchased this Levoit 200s humidifier with my own money, took pictures, and spent two weeks testing it for its noise level, output, and humidification performance.

Levoit has become a household name in both the humidifier and air purifier industries. Many of their humidifier models are popular in the market, and this 200s one is one of them. During my research, I pegged it as a value-for-money pick. But did it live up to my expectations? Keep reading this review to find out.

Levoit Dual 200S Humidifier Ratings Breakdown

Humidification Performance 8.5?

Although this Levoit dual 200s has many great features, its humidification performance is a bit below the average. Overall, it is a good humidifier for small to medium rooms, but not large rooms.

In my tests, it demonstrated a moderate output of 147ml per hour and effectively raised humidity from 42% to 49.6% in an hour in a 160 sq. ft. room. But It is not as powerful as some powerful ones, such as Vorndao EVDC500, which has an output of 250ml.

Ease Of Cleaning 9.5?

While it seems to have more components than many simple humidifiers on the market, each component is easy to disassemble, allowing for straightforward cleaning.

Though an ultrasonic model, this Levoit humidifier includes a filter that helps minimize mineral residue. However, I recommend daily tank emptying and weekly cleaning, as neglecting water change for over a week led to odor development in my experience.

The filter, located in the tank, could contribute to this smell if not regularly cleaned or replaced. Fortunately, replacements are affordable.

Noise Level 10?

The quiet operation of this humidifier is a standout feature. I barely notice it while working or sleeping, thanks to its extremely low noise levels of only 37.2dB on High mist and 35.9dB on Low mist.

ModeSound Level(dB)

It’s impressively unobtrusive, adding almost no extra noise to the room, which enhances the comfort without any disturbance.

Usability 9.5?

Setting up this Levoit 200s model is a breeze from my experience. After unboxing, it was just a matter of rinsing the parts, placing it on a flat surface, filling it with water, and plugging it in. Remembering to place the small filter in its housing is crucial, though.

Using it is just as straightforward. The two buttons on the front for controlling the mist level are pretty intuitive. But what I really love is the option to connect it to the Vesync APP. This app is user-friendly, and I personally prefer adjusting settings on my phone rather than physically interacting with the device.

I’ll delve more into the app functionality a bit later.

Build Quality 10?

This gadget boasts a robust build with each part smoothly finished and made from sturdy plastic. Based on my observation, it seems highly durable and not prone to easy damage, a testament to its solid craftsmanship.

Honestly, my trust in Levoit is based on consistent quality across all the humidifiers I’ve tested.

Warranty 9?

Like most Levoit humidifiers, this 200s model has a 2-year warranty. Their customer service is responsive. 

What Set This Levoit Dual 200S humidifier Apart?

Top Fill Design

Changing the water every day is recommended to prevent mold and bacteria growth, though I know many tend to skip this step.

The top-fill design of this particular model makes refilling less of a chore. I just remove the large cover and pour water straight in, being mindful not to splash the mist tube in the middle.

This simple yet smart design has saved me so much effort and time, making the daily refill process surprisingly hassle-free.

It is a smart humidifier

Even if it has a relatively low price tag, it is a smart humidifier!

Levoit has developed an APP for controlling their products called VeSync.Once you connect this 200s humidifier to it, you can turn it on/off and choose the mist mode via your phone.

In addition to that, you can set the target humidity level from 30% to 80% in auto mode and create a schedule or timer.

After trying out various smart products, I found that not every APP is easy to use. But this VeSync app is well-developed, and you can get the hang of it quickly. 

However, throughout my test, we found that the reading of the humidistat is not so accurate. Sometimes it would be a bit higher or lower. You can’t expect it to maintain the humidity level at a specific number you want. 

This model is also compatible with Alexa and Google Assistant.

It is compatible with essential oil

In most cases, you can’t put essential oil in a humidifier. But you can do it with this Levoit humidifier. 

As per my experience, most humidifiers that claim to have a diffusion feature will have an oil tray, but you can directly add essential oil to the base with this 200s model. Another model we found that has the same function is the Homech HM-AH004 humidifier.

It works just as well as a standard diffuser. But we recommend you clean it more frequently in this case.

While humidification performance is essential, aesthetical value is also important when choosing a humidifier.

Personally, I like the design of this Levoit 200s humidifier very much. The combination of a semi-transparent water tank and a white base is so simple and sleek that it can blend seamlessly with any decor. You no longer have to worry about color matching.

With a size of 11.8″H x 7.1″W x 7.1″D, its footprint is small, allowing you to put it on any table you want. Even better, based on my observations, it will not get everything wet.

In front of the base, there is a small rounded display with two buttons on either side – one for power and the other for mist level. If you don’t want to explore other functions, you can simply use the mist level button to switch between low, high, and auto settings.

The display will show you the humidity level, mist level, no water indicator (red), and if it is connected to the APP. The light of the display can be turned off through your mobile phone.

It is worth mentioning that this model doesn’t come with a nightlight. 


Price Range: $$$$$

From our previous discussions, it’s clear that the Levoit dual 200s model stands out with its advanced features and high-quality build. What makes it even more appealing is its affordability. In my view, its price point is not just reasonable but potentially even lower than the average for humidifiers with similar capabilities.

Whether you are looking for a humidifier to relieve coughs or improve dry skin, this Levoit dual 200s could be a good choice. You can get most of the advanced features at a low price.

I would recommend the Levoit dual 200s if you’re looking for the following features in a cool mist ultrasonic humidifier:

Want a humidifier for a small or middle-sized room: Keep in mind that the output of this humidifier is 147ml (according to my test), making it not a suitable option for large rooms. The recommended coverage is 290 sq. ft., and this model works great in my test room (160 sq. ft).

Want a smart humidifier: You can control this model via your phone. It can work with Alexa, google assistant, and its own VeSync APP. In this way, this humidifier can turn on and off automatically as per your order. 

Want to fill the water from the top: Once you decide to use a humidifier, you need to refill it frequently. This 200s model has a big top cover to fill the water from the top. It can save you a lot of effort.

Want a diffusion function: Levoit dual 200s humidifier is compatible with essential oils. You can add essential oil into the base chamber so as to reap added benefits for relieving coughing or sore throat.

Hope this Levoit dual 200s humidifier review from Airsmartly can help you out!
