Boneco U700
No longer sold by Boneco in the US Boneco's US site (boneco.us) now redirects to a page that does not exist, and its only store is a Swiss one selling 230-volt units in francs (October 2026). Shown for comparison; the figures here are for the US model as it was sold.
Four gallons a day from a tabletop unit, which puts the U700 level with Vornado's Evap40 console on output while taking up a fraction of the floor. Its 1,000 sq ft figure lands within two percent of the load calculation - Boneco and Vornado both print numbers the physics backs up. Its nine-litre tank still lasts only fourteen hours at full tilt, which is the recurring lesson of this category: capability and refill interval trade against each other and no amount of marketing changes it. The self-cleaning mode is genuinely unusual at any price.
The room-size claim, reconciled
985 sq ft supported · box says 1,000 sq ft
The 1,000 sq ft on the box is what the winter load calculation supports for this output — one of 18 units here whose claim lands within 5% of its own published rate.
Holding 1,000 sq ft takes about 4.06 gal/day, which drains this 2.38-gallon tank in roughly 14 hr.
What a year costs
A250 demineralisation cartridge at roughly $20, replaced every two to three months in hard water. Electricity assumes the rated 490 W for 12 hours a day across a 150-day heating season at 16¢ per kilowatt-hour.
Specifications
A claim the maker makes
Boneco says the included Ionic Silver Stick uses silver's antibacterial effect to keep the water clean. We quote it rather than repeat it: this site has not tested it and neither has anyone independent.
Maintenance profile
- Top fill
- Yes
- Replaceable media
- Demineralisation cartridge
Facts, not a score. Which of these matter depends entirely on whether the unit ends up somewhere you will actually clean it.
Features
- 4 gal/day published output against a 1,000 sq ft claim
- 9L top-fill tank
- Warm or cool mist
- Self-cleaning mode
- A250 demineralisation cartridge and Ionic Silver Stick
- Digital display, timer and auto mode
Pros
- Console-class output from something that sits on a side table
- Coverage claim within a couple of percent of the standard load calculation
- The self-cleaning cycle addresses the failure mode that kills most humidifiers
- Demineralisation and silver-stick water treatment both included rather than sold on
Cons
- 490W on the warm setting is the highest draw in the catalog outside the whole-house steam units
- Fourteen hours at full output from a nine-litre tank
- $400, and the cartridges keep coming
- Nine litres of water on a side table is a lot of weight in a plastic tank
The pros and cons above are drawn from the maker’s documentation and published specifications. There is not yet a body of owner reports for this model that we have read.
What owners say
No owner discussion collected for the Boneco U700 yet. The pros and cons above come from the maker's documentation and published reviews, and this section will fill in when there is enough first-hand material to summarise honestly. We would rather leave it empty than invent it — how we compare explains why.

Swiss, expensive, and unusually straight about what it does: 3.17 gallons a day published, against a 650 sq ft claim that the load calculation puts at 780. A maker printing a number 17% below what its own output supports is doing something almost nobody else in this catalog does. It pairs a demineralisation cartridge with an Ionic Silver Stick for the water, so the two failure modes of a cheap ultrasonic - dust on the furniture, life in the tank - both have a specific countermeasure. The tank is only 5 litres, which at full output is about ten hours.

An air washer works by turning textured evaporator mats through a water bath: air passes over the wet surfaces, picks up moisture, and drops some dust on the way. The appeal is that the mats are washed rather than bought by the season - Boneco says they go in the dishwasher or the washing machine - though it does sell replacement mats. Boneco's technical data gives 350 grams an hour, which is 2.22 gallons a day and supports about 547 sq ft, so the 540 on the listing is one of the few coverage claims in this catalog that its own maker's output figure actually backs. The rest of the arithmetic is as plain: a 4.5-litre bath, one silver stick a year, no filters, and about thirteen hours between fills if you are running it at the room it claims.

Carepod
Carepod Cube Plus X50V
The One Plus with a heater, which buys warm mist and - more interestingly - a one-touch cycle that boils the tank to sterilise it. Between a steel water path and a heat-sanitise button, this is as close as the category gets to solving the hygiene problem outright, and it is priced accordingly at $450. Carepod buries its output rate in a feature graphic rather than a spec table, which is a shame because it is one of the better ones here: 440 mL/h on warm is 2.79 gallons a day, and that makes the 700 sq ft on the listing very nearly honest. The catch is the tank. At that output 4.2 litres is gone in about ten hours, against the 32 advertised at the lowest setting.
