fourth humidifier I've tested + I'm head over heels for this one -- highest rate on the market at 700ml/h, highest capacity tank as well at 6.5L, accurate to w/in 5-10% humidity sensor (unlike its predecessor that was off by 20%). SILENT!!! its predecessor I've woken up countless morning thinking it's raining outside, essentially living next to a glorified water boiler. also LOVE that it's speckled opal matte textured + not tacky shiny.
