## Description

Ultrasonic Humidifier

Review: I recently purchased the Dreo Smart Humidifier, and I'm quite pleased with its performance. Here are my key takeaways: 1. **Easy Setup**: The humidifier was straightforward to set up right out of the box. The process took only a few minutes, making it user-friendly for anyone. 2. **Water Requirements**: It's important to note that the Dreo humidifier operates best with distilled water. I've been using Winstons ARION Distilled Water (100% Pure Steam Distilled Water, 5 Litres by UINCLU), which has proven effective in maintaining optimal performance. 3. **Cleaning and Maintenance**: For continued efficiency and quality, it’s essential to clean the unit and change the water every 100 hours. This routine maintenance ensures the humidifier functions properly and delivers the best results. 4. **Improved Air Quality**: The humidifier has significantly improved the air quality in our bedroom. Our room's humidity level was around 32%, which is quite dry. With the Dreo humidifier, we’ve been able to increase it to the recommended 45%-50%. 5. **Relief for My Son**: Most importantly, the humidifier has benefited my 4-month-old son, who previously struggled to breathe comfortably at night. The increase in humidity has alleviated his nighttime breathing issues, making for more peaceful sleep. 6. **Design and Features**: The humidifier has a modern design and is relatively quiet, which is crucial for use during the night. The additional smart features, like scheduling and adjustable mist levels, add to its convenience. In conclusion, the Dreo Smart Humidifier is a reliable solution for improving bedroom humidity. With proper maintenance and the right water, it has proven invaluable for our family, especially for my young son. I highly recommend it for anyone dealing with dry air issues.
Review: Quick delivery and nicely packed. It works great. Very good for standard rooms size. Not for massive or very big rooms. It detects humidity ratio in the room and App works fairly well. Good product. I hope it will last, so let's see its performance after a few months of use. For the moment I consider it to be a great choice.
