How We Tested These Humidifiers

In our evaluation process, we set a high bar for all the humidifiers we tested. After all, we aimed to unearth the best ones available.

One critical element we looked at was the noise level of each humidifier. We know how disturbing a loud humidifier can be, especially when trying to sleep or focus on work. We used a decibel meter at varying distances to measure the exact noise output in different settings to test this. Our top picks are those humidifiers that are efficient and quiet enough to fade into the background.

Humidity levels were another critical aspect of our testing. We used a high-precision hygrometer to monitor the changes in humidity over time. We placed each humidifier in rooms of different sizes and measured how efficiently and quickly it could raise the humidity level to the desired point. We considered both the peak humidity level the machine could achieve and how evenly it could maintain the humidity across the room.

Factors We Considered When Choosing the Best Humidifier

When choosing the best humidifier, we focus on several essential factors. Each plays a critical role in the humidifier's effectiveness and convenience; understanding them will allow you to make an informed purchasing decision.

Room Size

The size of the room where you plan to use the humidifier is critical to consider when choosing the best humidifier for your needs. Humidifiers come in various sizes and capacities, designed to accommodate different room sizes effectively.

A tabletop or portable humidifier would suffice for small rooms like a bedroom or home office. These are compact units that you can easily move around, and they can efficiently increase moisture levels in small spaces. Our testing focused on how these units performed in a 10x10-foot room. This 100-square-foot space lets us compare how well these machines raised humidity levels and how quietly they operated in a space replicating many bedrooms or bathrooms. 

For medium-sized spaces such as living rooms or master bedrooms, you might need to consider a console humidifier. These are larger units with a higher moisture output than tabletop models, suitable for maintaining ideal humidity levels in larger areas. To replicate this environment, we tested units in our 12x20-foot conference room and 12x18-foot living room.

It's important to note that choosing a humidifier with a capacity too small for your space may lead to inefficient humidification. At the same time, an overly large one might produce excessive moisture, leading to condensation on windows and other surfaces. Always consider your space size when choosing a humidifier!

Type of Humidifier

Choosing the correct type of humidifier is crucial because it affects how the unit adds moisture to your air, how easy it is to maintain, and what kind of mist it emits. Our testing focused on three types, each with its unique characteristics.

  1. Evaporative Humidifiers: These use a fan to blow air over a wet wick or filter to create a cool mist. While they're typically louder due to the fan operation, they're also self-regulating—as humidity increases, their ability to add more moisture decreases. The results of our comparative testing eliminated evaporative units for most environments except for large spaces where their increased tank capacity was a benefit. We identified the Venta LW25 Airwasher as the best humidifier for large rooms like these.  

  2. Ultrasonic Humidifiers: Ultrasonic humidifiers produce a cool mist by vibrating water at an ultrasonic frequency. They're generally quieter and more energy-efficient than evaporative models, making them an excellent bedroom choice. The LEVOIT OasisMist 1000S 10L Smart Humidifier, our choice for the best overall humidifier, and the Pure Enrichment MistAire, our choice for the best cool mist humidifier, fall into this category. 

  3. Warm Mist Humidifiers: These humidifiers boil water to produce a warm mist, making a room feel warmer. They're usually quieter than evaporative models but can make a room uncomfortably warm during the hotter months. The Levoit LV600S Smart Hybrid, which we use primarily in cool mist mode, also supports warm mist operation. 

The type of humidifier you choose depends on your specific needs, the size of the space you want to humidify, and personal preferences regarding noise level and mist temperature.

Humidity Control

Humidity control refers to a humidifier's ability to maintain the desired humidity level in your space. A humidifier with a built-in hygrometer, also known as a humidity sensor, can measure the amount of moisture in the air and adjust its output accordingly. Some advanced models even offer a fully automatic mode, adjusting to keep the humidity in a predefined healthy range, generally around 30-50%.

While all humidifiers will increase the humidity in a room, models with a built-in hygrometer and adjustable humidity settings give you more control. You can set a precise level, and the device will automatically turn on or off to maintain it, avoiding over-humidification, which can lead to problems like mold and mildew growth.

If you live in an area with significant seasonal changes in humidity or have specific health needs that require precise humidity control, a model with an integrated hygrometer would be particularly beneficial. A basic model without a hygrometer should be enough if such precision isn't necessary.

Remember, maintaining proper humidity levels is essential for your health and comfort, as well as for the well-being of your home, including your furniture, plants, and pets.

Maintenance and Cleaning

Accumulated water can become a breeding ground for bacteria, mold, and mineral deposits. So, it's essential to clean your humidifier regularly. Some models make this task easier than others with design features like removable tanks and wide openings for better access.

Cleaning frequency varies depending on the model and the hardness of your water, but generally, cleaning your humidifier at least once a week when in use is recommended. Always follow the manufacturer's cleaning instructions to ensure optimal operation and prolong the device's life.

Maintenance also involves changing or cleaning filters if your humidifier uses them. Some models use replaceable wick filters to absorb the water before evaporating. These need to be changed regularly, depending on the hardness of your water and the frequency of use.

In addition, consider the ease of refilling the tank. Some tanks are awkward to fill, while others have a top-fill design that makes the task more convenient. Some even have a removable tank that can be filled at the sink.

In summary, for the best experience, look for a humidifier that is easy to clean, refill, and maintain. These factors may seem minor, but they can significantly affect your satisfaction with the product over time.

Noise Level

Noise level is essential when choosing the best humidifier, especially if you plan to use it in a quiet environment like a bedroom or study. Its type and operation mechanism determines the noise a humidifier generates.

Ultrasonic humidifiers are generally the quietest, using high-frequency sound waves to create a cool mist. They are usually barely audible, with a light humming sound, making them ideal for bedrooms or offices.

On the other hand, evaporative humidifiers use a fan to blow air through a wet wick filter, which can create a noticeable fan noise. While some people might find this white noise soothing, others may find it disruptive, especially during sleep.

Moreover, the noise level can vary from model to model, even within the same type. Many humidifiers offer multiple speed settings. The highest speed setting may produce more noise but also more mist, while the lowest setting will be quieter but with reduced output.

In summary, if noise concerns you, opt for an ultrasonic humidifier or a model with adjustable speed settings that allow you to control the noise level according to your preference and the situation.

Additional Features

Additional features can significantly enhance the functionality and convenience of a humidifier, making it more suited to your specific needs and lifestyle. Here are some extra features to look out for:

  1. Timer: A timer allows you to automatically set the humidifier to turn on or off at specific times. This can be helpful if you want the device to start running before you arrive home or don't want it to operate while you're out.

  2. Auto Shut-Off: This feature automatically turns the humidifier off when the water tank is empty, preventing damage to the unit and ensuring safety.

  3. Humidistat: A built-in humidistat can monitor the humidity level in the room and adjust the output accordingly, maintaining the desired humidity level. Some sophisticated models even allow you to set a specific humidity level.

  4. Remote Control: Some humidifiers come with a remote control, allowing you to adjust settings from a distance.

  5. Adjustable Mist Output: This feature lets you control the amount of mist the humidifier emits, allowing you to tailor it to the size of your room or your personal preference.

  6. Aroma Diffuser: Some humidifiers have a compartment for adding essential oils, turning the device into a 2-in-1 humidifier and aroma diffuser.

  7. Nightlight: A built-in nightlight can be valuable in a bedroom or nursery.

  8. Filter-Free Design: Some humidifiers are designed to work without filters, which can save you from the cost and effort of regular filter replacements.

  9. Easy-to-Clean Design: Features like a removable tank, wide tank opening, or dishwasher-safe components can make cleaning the humidifier much easier.

Remember, while these features can offer additional convenience, they might also add to the cost of the device. So, knowing which features are most important to you and align with your specific needs when choosing a humidifier is essential.
