I ordered this Pure Enrichment MistAire Ultrasonic humidifier about a month ago. I was preparing to order new filters after noting that the filter in my unit was moldy after only about 2 weeks’ use. Those moldy filters are bad for my health, another disposable in the landfill, and a constant cost. When I saw this unit, I knew it was a better choice, and it hasn’t disappointed me. It’s easy to fill, and virtually silent. I’m very happy with this purchase!
