Vicks V745A Warm Mist Humidifier Review
A one-gallon warm-mist humidifier that boils the water — no filter, no white dust, a little warmth, and a cup for VapoSteam when someone's sick.
The verdict
The V745A is the cheap, effective winter humidifier for a bedroom or nursery: it boils water and releases it as a warm, visible mist, which means it's sterile on the way out, needs no filter, and leaves no white dust regardless of your tap water. A one-gallon tank runs a night and then some on low, there's a medicine cup for Vicks VapoSteam during cold season, and it shuts off when empty. The trade-offs are a hot unit (keep it out of reach of small kids), the most scale cleaning of any type, and no humidistat.
Typical price: ~$39 (typical street price — current price shown on Amazon)

Full review
Warm-mist humidifiers are the old-fashioned type for a reason that still holds up: boiling the water before it leaves the unit sterilizes it and leaves the minerals behind in the tank, so you get clean, dust-free moisture from any tap water with no filter to buy. The Vicks V745A is the standard one, it costs about what a nice dinner does, and it's the unit a lot of families reach for the first time a winter cold hits.
The one-gallon tank runs about a night on low, the mist is visible and slightly warming near the unit, and the medicine cup takes VapoSteam for a menthol vapor that genuinely helps a stuffy kid sleep. It's quiet — a faint boil rather than a fan — and shuts itself off when the tank runs dry. There's no humidistat, so you run it by setting and check a hygrometer; on low in a closed bedroom it's hard to overdo.
Two cautions. The unit and the steam are hot: put it on a dresser out of a toddler's reach, not on the floor by the crib. And the heating element collects scale faster than any other type — a weekly vinegar soak is non-negotiable, or output drops and it starts to smell. Accept those, and it's the most affordable way to take the sting out of dry winter bedroom air.
Best for: Bedrooms and sickrooms on a budget; hard-water households that want no filter and no dust and will place it out of a child's reach.
