Our take on the Honeywell 1 Gallon Filter Free Warm Mist Humidifier HWM845B

The Honeywell HWM845B is a warm mist humidifier with a 1-gallon tank and no filter to replace. It heats water to release up to 95% bacteria-free moisture and runs up to 24 hours on low, with two output settings. It suits medium rooms and people who want warm mist without filter costs. Against cool mist rivals it adds warmth and an essential oil diffuser, but it uses more power and has a smaller tank than large console units.

Questions and answers

Does it need a filter?
No. It is filter-free, so there are no replacement filters to buy. You only need to clean mineral scale regularly.
How long does the tank last?
Up to 24 hours on the low setting. On high output it runs out sooner, so expect more refills in that mode.
Is warm mist safe around children?
The mist is warm and the unit heats water, so keep it out of reach of small children. It shuts off automatically when the water runs low.
Can I use essential oils?
Yes. It has a built-in diffuser for essential oils, so you can add scent to the mist.
What rooms does it suit?
Medium rooms such as bedrooms and living rooms. For large open spaces a bigger console humidifier holds more water.
Does it use much electricity?
More than a cool mist humidifier because it heats the water. That is the trade-off for warm mist and bacteria reduction.
