10 Best Humidifiers 2025 in the UK

The LEVOIT Humidifier is a cool mist humidifier designed with ease of use and quiet operation in mind, making it highly suitable for bedrooms and nurseries. With a noise level as low as 26dB, it ensures a peaceful sleeping environment. Its 2.5-liter tank allows it to run up to 25 hours on low, offering continuous humidification throughout the night, which is beneficial for relieving congestion and dry throat.

A standout feature is its top-fill design, simplifying the refilling process and minimizing spills. The large opening also makes cleaning straightforward, reducing maintenance efforts. The 360-degree rotating nozzle allows for customizable mist direction, enhancing user control over the humidification process.

Safety is addressed with an automatic shut-off feature that activates when the water level is low, ensuring peace of mind during use. However, it's important to note that this humidifier does not support the use of essential oils, which might be a drawback for those looking to use it for aromatherapy.

This humidifier is lightweight and portable, weighing only 1.34 kg, making it easy to move around the house. While it excels in small to medium-sized rooms, it may not be as effective in larger spaces. Additionally, the recommendation to use purified or distilled water could increase operational costs for some users.

The Honeywell 300 CFM Indoor Portable Evaporative Cooler combines three functions in one: it cools, humidifies, and fans small spaces, making it a versatile choice for areas under about 60% humidity. Its 2.6-gallon detachable water tank is fairly large, allowing for longer use between refills, and it’s easy to clean. This unit is best suited for personal spot cooling—like near a bed, desk, or sofa—rather than cooling an entire room.

It runs quietly with three speed settings and includes a carbon dust filter to help keep air clean. The remote control and energy-saving timer add convenience and help manage power use. Since it uses evaporative cooling (no compressor), it’s more energy-efficient and environmentally friendly than a traditional air conditioner, but it won’t cool as dramatically, especially in very humid conditions. It has safety features like thermal overload protection and a sturdy heat-safe casing, which is reassuring.

Maintenance is straightforward but regular cleaning of the filter and tank will be needed to keep performance optimal. The main drawback is that it’s not suitable as a full room air conditioner, so it might not meet the needs of those looking for strong cooling power. Also, its 2-star energy rating suggests moderate efficiency compared to other models. This makes it a practical and safe choice if you want a combined humidifier and cooler for a small personal space, offering decent features without the higher cost or complexity of an AC unit.
