I purchased the Vicks Filter-Free Warm Mist Humidifier (V745WB) in January 2025 to solve a specific problem for me, and it worked.
This is a warm mist humidifier designed for bedrooms, larger rooms, and other indoor spaces that need added moisture during dry weather. In my case, I bought it to help offset the very dry winter air in my home.
My home is all electric and uses a heat pump, which I monitor with a Nest thermostat I reviewed here. Winter air naturally holds significantly less humidity than warmer seasons, and once indoor heating systems turn on, moisture levels can drop even further. This combination creates an especially dry sleep environment, which can affect everything from breathing to skin and, ultimately, how well you rest at night.
I already have sleep apnea, so I purchased the Vicks humidifier to level the playing field a bit.
The humidifier is rated to cover up to 500 square feet, which is more than enough for a 20′ × 25′ room. With its one-gallon tank, you can get up to 24 hours of whisper-quiet operation. It has two humidity settings and an automatic shut-off, giving you full control. I use essential oils with mine. The manufacturer states that you can add Vicks VapoSteam for temporary relief from cough and congestion associated with colds, flu, allergies, or dry air. I’ve used this unit for approximately 425–450 hours over the last two winters without any abnormal noise or operational issues.
