Frequently asked questions
Evaporative vs ultrasonic?
Ultrasonic sprays a fine mist (can leave white mineral dust from hard water and over-humidify); evaporative blows air through a wet filter — no dust, self-limiting humidity, but a fan hum and a filter to replace. Hard water or sinus-sensitive: evaporative.
What's the white-dust issue?
Ultrasonic units aerosolize your water's minerals as visible dust on furniture. Honeywell's evaporative design eliminates it entirely.
Is the fan too loud for sleep?
It's a steady hum — some find it a white-noise bonus, light sleepers may prefer a silent ultrasonic. Try the low speed.
Filter cost?
Wicks need replacing every 1-3 months — the ongoing cost ultrasonic units don't have, offset by no white-dust cleanup.
