Review on BONECO W300 Humidifier Air Washer by Aaron Wilson

I needed a humidifier and wanted something that didn't require a lot of filter replacements. Ultrasound doesn't work for me because my tap water has too many minerals that leave a white film of dust everywhere. I used to have an air washer type machine but it was difficult to clean it well. The reason I chose this one is because the filter is washable and seems to last a while. I've only had this unit for a few days, but it doesn't seem to add much moisture to my dry air. As that was the main reason I bought it, I'm a bit disappointed. When I started using it my humidity was 17%. Now 23-24%. Better but not great. The room I'm using it in is about 450 square feet, so it's within the room guidelines.
