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 PELONIS 3-in-1 Air Cooler is a versatile device that works as an evaporative cooler, fan, and humidifier, making it a good choice for those living in dry or hot climates who want added moisture in the air along with cooling. Its 5-liter water tank can run up to 10 hours, which is convenient for overnight use or long periods without refilling. The humidifying effect comes from evaporating water, so while it adds moisture, it won’t cool the air as much as an air conditioner since it doesn’t use refrigerants.

With an airflow capacity of 330 cubic meters per hour and 60° oscillation, this air cooler is best suited for small to medium rooms like bedrooms or offices. Noise level sits around 52 dB, which is relatively quiet but not silent—quiet sleep mode helps reduce noise for nighttime use. Maintenance is straightforward: the water tank is easy to refill, and the removable filter can be cleaned to keep the air fresh and free of germs. The remote control and 7-hour timer add convenience, allowing you to adjust settings without getting up.

Energy efficiency is a plus compared to traditional air conditioners, helping save on electricity costs. It is heavier than some portable humidifiers at 5.7 kg and requires floor space. This product suits users who want a multi-purpose device that cools, humidifies, and fans efficiently in dry environments, while those needing true air conditioning or ultra-quiet operation might want to consider other options.
