The MistAire Eva 4 Speed Evaporative Humidifier works as it should. It’s silent and I don’t see any mist coming out, which I like. I’ve tried it on 2hr, 4hr, and 8hr settings (level 1) and it’s really helped us not to feel so dry since the air in our apartment this winter is incredibly dry. I also like the sleep mode, so there are no lights showing while we sleep at night. I’m so happy with our purchase!
