I have been using the Pure Enrichment MistAire™ Eva 4-Speed Evaporative Humidifier for over a year and I must say I am impressed with it. I bought another high selling evaporative humidifier. But the Pure Enrichment MistAire™ blows it out of the water. It's compact and has effective three speeds (I can measure the changing humidity levels using a hygrometer). I am happy that I bought this humidifier and if given a chance would by again.
