I purchased this humidifier for use in our home in the dry environment of mountainous Northern New Mexico. I purchased it after doing alot of research on quietness, ease of cleaning, low cost maintenance, ease of filling with water. I think that I made a great choice. Adding water is a snap, and cleaning the filter is really easy. The noise level is acceptable. The added bonus of either cool or warm mist is a plus. It is great for a large room.
