For most people using tap water, the winner is the Vornado EVAP40 if you want zero filter hassle and maximum toughness. Go with the Levoit LV600S if you want a pretty face with a hidden tap-water superpower.
And if you’re feeling old-school, the Vicks Warm Mist will make you feel like you’re in a cozy cabin, even if it sounds like a plumbing experiment gone right.
