10 Best Humidifiers

The Levoit Smart Cool Mist Top Fill Humidifier is designed mainly for bedrooms or small rooms up to around 27 square metres (290 square feet). Its 3-litre water tank offers up to 25 hours of continuous mist, so you won’t need to refill it too often. The top-fill design is very user-friendly, making it easy and clean to add water without flipping the tank over, which is a plus for maintenance. It also includes a large opening that simplifies cleaning, though the manufacturer recommends cleaning the tank every three days to keep it in good shape. Noise-wise, this model is impressively quiet at just 19dB, making it suitable for light sleepers or use during the night without disruption.

A notable advantage is its smart features: you can control it via a dedicated app or voice assistants like Alexa and Google Assistant, allowing you to adjust humidity settings remotely or set schedules conveniently. The built-in sensor and automatic humidity control help maintain an optimal indoor moisture level between 40-50%, which is comfortable and healthy. Additionally, it doubles as an essential oil diffuser, letting you add a personal touch with aromas to improve your room’s atmosphere.

On the downside, while the auto mode stops misting if humidity rises above 50%, you need to manually adjust settings to continue misting, which might require some user attention. Also, regular cleaning is necessary to maintain performance and device lifespan, which some users might find a bit demanding. This humidifier is a great choice for those wanting a quiet, smart, and easy-to-use device for small rooms, especially if you like the convenience of app or voice control and enjoy using essential oils.

The Dreo Humidifier is a good choice if you're looking to improve air moisture in medium-sized rooms, up to around 300 square feet, which covers most bedrooms or nurseries. It uses ultrasonic technology to release a fine, cool mist that evenly humidifies without making your furniture damp. The 3-litre water tank is quite generous, allowing for up to 30 hours of continuous use, meaning you won't need to refill it often. The top-fill design is practical and simple, making refills less messy. Noise level is very low at 26 decibels, which is quieter than a whisper, so it won’t disturb your sleep or that of a baby.

This humidifier also offers adjustable humidity control and has a digital display to make settings easy to see and use. Plus, it features a gentle night light with adjustable ambient lighting, which can help create a calming bedroom atmosphere. An added benefit is the aroma pad tray, so you can add essential oils for a spa-like experience. On the maintenance side, it includes a cleaning brush, but to keep the mist clean and free of mineral buildup, you might want to invest in Dreo’s additional cartridges designed to reduce limescale and dust. These extra cartridges are sold separately, so factor that into your ongoing costs.

The minimalist black design is simple and should blend well with most room styles. While it's a bit heavier than some small humidifiers, it remains easy to handle. This humidifier effectively balances quiet operation, long run time, and useful extra features, making it suitable for anyone wanting a reliable, low-maintenance device for their bedroom or nursery.

The Levoit Humidifier Dual 150 is a solid choice for anyone looking to improve air moisture in medium to large rooms, up to around 290 square feet. Its 3-litre water tank is generous and can run quietly for about 25 hours without needing a refill, which is handy if you want continuous comfort through several nights. It operates very quietly, around 28dB, so it won't disturb light sleepers. The easy top-fill design is user-friendly, eliminating the hassle of flipping the tank to fill it and reducing spills. It also has a 360-degree rotatable nozzle, allowing you to direct the mist where you want it, which improves its effectiveness.

On top of basic humidifying, it doubles as an essential oil diffuser and has a gentle night light, adding a relaxing atmosphere to your bedroom or nursery. Automatic shut-off when the water runs out adds safety and peace of mind. Maintenance requires cleaning every few days and monthly filter sponge changes, which is fairly standard but something to keep in mind if you want low upkeep. Some users might find the need for regular cleaning a bit of a chore, but it helps maintain performance and hygiene.

The humidifier’s size and 3L capacity make it less suitable for very large open spaces but ideal for bedrooms, offices, or plant care. Support from the manufacturer is noted as responsive, which is reassuring if you encounter issues. The Levoit Dual 150 balances quiet operation, ease of use, and useful extras in a compact design, presenting a reliable and pleasant addition to your home environment.
