ULTRASONIC HUMIDIFIER -- ABSOLUTELY SILENT
I previously purchased the same model and was very pleased with it. It is easy to operate and runs absolutely silently. It does come with a permanent ceramic filter. However, if you have hard water locally and use it in the humidifier, the filter can eventually get clogged. Your options are: 1) Buy "de-mineralization" filters (from Amazon or the manufacturer - Air Innovations), or 2) Use distilled water. I use only distilled water, which eliminates that annoying "white mineral dust" throughout the room. My only complaint was the humidifier was NOT shipped in a standard Amazon box. Instead, it was shipped in the original mfg. box with my address label stuck on it. This was a bad procedure for two reasons. First, no security (possible package thieves) and second, damage in transit. My humidifier arrived in great condition, but the box had a hole and a few "dings" in it. I completely recommend it for use in small rooms (up to 400 sq. ft.).

This is our 2nd year with this humidifier. It is quiet and easy to clean. I wish it top filled but I like it so much I bought another one as a gift!

Saving our sinuses
This has helped make our home so much more comfortable by keeping the humidity level high enough when we run the hot air heat.
