Our take on the BONECO U300 Cool Mist Ultrasonic Humidifier

The BONECO U300 is a cool-mist ultrasonic humidifier rated for rooms up to 540 square feet. It uses a demineralization filter to cut white dust, and it has a built-in humidistat plus automatic shutoff when the tank runs dry. It holds 7.7 lb of water and stands 12.75 inches tall, so it fits on a floor or low table.

Questions and answers

Is the BONECO U300 worth it?
It is a reasonable pick if you want a filtered ultrasonic unit with a humidistat for a room up to 540 sq ft. If your water is very hard, budget for filter replacements or consider a evaporative model.
How is it different from the BONECO U200?
The U300 covers a larger area and adds a humidistat with automatic shutoff. The U200 is smaller and better suited to a single bedroom.
Does it really stop white dust?
The demineralization filter captures minerals before they reach the mist, which cuts white dust noticeably. In very hard water you will still see some residue and need to change the filter more often.
What comes in the box?
The humidifier, a demineralization filter and a manual. Water is not included, and replacement filters are sold separately.
Can I use tap water?
Yes, tap water is fine, but the filter is what keeps minerals out of the mist. Distilled water extends filter life.
When is it cheapest?
Prices on ultrasonic humidifiers tend to dip in spring and early summer, outside heating season. Watch the price history for a drop below the recent range.
