Noise Level
Its quiet operation makes it ideal for bedrooms and workspaces, with only the highest setting producing moderate noise.
Maintenance and Cleaning
The unit’s design allows easy top-off refills and cleaning, preventing mold and musty smells with minimal effort.
Additional Features
Smart features like automatic mode adjustments and scheduling add convenience and enhance the overall experience.

The Blueair 2-in-1 Purify + Humidify is a unique combo device that does more than just add moisture to the air; it also purifies it. It uses advanced HEPASilent technology to clean the air while the 360° InvisibleMist system humidifies, making it a great choice if you want fresher and more balanced air in your home. It covers up to 500 square feet for humidification, which suits medium-sized rooms, while its air purification capacity can handle up to 1,726 square feet in an hour.

The water tank is designed for easy top-off refills without needing to remove it, which is convenient and reduces mess. A smart water pump and chip indicator alert you when it’s time to refill, helping you keep the humidifier running smoothly. Noise levels are kept low, making it suitable for bedrooms or workspaces. Cleaning is simple with a large tank opening and no tricky spots, helping to prevent mold or musty odors. An added feature is the auto drying mode that ventilates the wick to keep it fresh.

On the downside, the unit is relatively large and heavy at 20 pounds, so it might not be easy to move around. While it’s a strong all-in-one air care device, if you only need a humidifier for very large spaces or very specific humidity control, other dedicated models might serve better. For those seeking the convenience of both air purification and humidification packed into one quiet, easy-to-maintain device, this Blueair model is a solid option.

The LEVOIT Smart Cool Mist Humidifier is a solid choice for a bedroom humidifier, especially if you appreciate modern convenience. Its 3-liter water tank is large enough to cover a medium room size (up to about 290 square feet), which fits well with most bedrooms, keeping the air comfortably moist without frequent refills. The top-fill design is quite user-friendly—no spills or tank flipping—and cleaning is easier thanks to a wide opening.

One of its standout features is smart control: you can adjust humidity through the Vesync app or with voice assistants like Alexa and Google Assistant. The built-in humidistat automatically maintains your desired humidity, so you don’t have to keep adjusting it manually. It also supports scheduled operation and timers, helping you tailor it to your daily routine. Noise level is impressively low thanks to its NoiseDefender design, making it suitable for light sleepers or use at night. Additionally, it can diffuse essential oils, adding a pleasant scent to your room, which is a nice bonus if you enjoy aromatherapy.

Since it uses ultrasonic technology, you’ll get fine mist output without heat, which is safer and energy-efficient. The humidifier includes pre-filter sponges to keep the water clean, but you’ll still need to clean it regularly to avoid buildup. While the 290 square feet coverage is ideal for bedrooms, it may be insufficient for larger living spaces. The unit is lightweight and compact, which makes it easy to move and fits on bedside tables without taking up much space. However, it requires a bit of care to avoid overfilling and to maintain the filters properly for best performance. Customer support from LEVOIT is known to be helpful, which adds peace of mind. If you want a smart, quiet, and easy-to-use humidifier tailored mainly for bedroom use with helpful extras like app control and essential oil diffusion, this model is a great pick.

Buying Guide for the Best Humidifier

Choosing the right humidifier can significantly improve the air quality in your home, making it more comfortable and healthier, especially during dry seasons. When selecting a humidifier, it's important to consider several key specifications to ensure it meets your needs. Understanding these specs will help you make an informed decision and find the best fit for your environment.
Type of HumidifierHumidifiers come in different types, including evaporative, ultrasonic, steam vaporizers, and impeller. Each type has its own method of adding moisture to the air. Evaporative humidifiers use a fan to blow air through a wet wick, while ultrasonic models use ultrasonic vibrations to produce a fine mist. Steam vaporizers boil water to create steam, and impeller humidifiers use a rotating disk to fling water at a diffuser. The type you choose depends on your preferences for noise level, maintenance, and the specific needs of your space. For example, ultrasonic humidifiers are generally quieter and more energy-efficient, making them suitable for bedrooms.
Room Size CoverageThis spec indicates the maximum room size that the humidifier can effectively humidify, usually measured in square feet. It's important because using a humidifier that's too small for your room won't provide adequate moisture, while one that's too large may over-humidify and cause condensation issues. Room size coverage is typically divided into small (up to 300 sq. ft.), medium (300-500 sq. ft.), and large (over 500 sq. ft.). To pick the right one, measure the room where you plan to use the humidifier and choose a model that matches or slightly exceeds that size.
Water Tank CapacityThe water tank capacity determines how long the humidifier can run before needing a refill. This is important for convenience and continuous operation, especially overnight. Capacities can range from small tanks (under 1 gallon) to large tanks (over 2 gallons). If you need a humidifier for a large room or want it to run for extended periods without frequent refills, opt for a model with a larger tank. For smaller rooms or less frequent use, a smaller tank may suffice.
Humidity ControlHumidity control features allow you to set and maintain a desired humidity level in your room. This is crucial for comfort and health, as too much or too little humidity can cause problems. Basic models may have manual controls, while advanced ones offer digital displays and automatic sensors to adjust humidity levels. If you want precise control and ease of use, look for a humidifier with built-in hygrometers and automatic shut-off features when the desired humidity is reached.
Noise LevelThe noise level of a humidifier can affect your comfort, especially if you plan to use it in a bedroom or a quiet space. Noise levels are usually measured in decibels (dB). Ultrasonic humidifiers are known for being quieter, while evaporative and steam models can be noisier due to fans and boiling water. If you are sensitive to noise or need a humidifier for a quiet environment, consider models specifically designed to operate quietly.
Maintenance and CleaningRegular maintenance and cleaning are essential to keep your humidifier running efficiently and to prevent the growth of mold and bacteria. Some models are easier to clean than others, with features like removable tanks and dishwasher-safe parts. Consider how much time and effort you're willing to invest in maintenance. If you prefer low-maintenance options, look for models with easy-to-clean designs and antimicrobial features.
Additional FeaturesSome humidifiers come with additional features that can enhance their functionality and convenience. These may include timers, remote controls, essential oil diffusers, and night lights. While not essential, these features can add value and improve your overall experience. Think about which extra features might be beneficial for your lifestyle and choose a model that offers those options.
