HoMedics TotalComfort Deluxe
A tower with a 1.47-gallon tank, a demineralisation cartridge in the box, and a 426 sq ft claim - an oddly specific number that at least suggests somebody calculated rather than rounded up to 500. HoMedics now lists it as the Decor Series Large Humidifier, and its box gives the CMTF91 a 17-18 dBA noise figure, which with the cartridge makes it one of the quiet, dust-free units here. Seventy hours on the lowest setting is among the longest here, which as usual means the lowest setting moves very little water: about half a gallon a day. Where it earns its place is the combination of a demineralisation cartridge and a real humidistat at $100, which most rivals at this price do not offer.
The room-size claim, reconciled
123 sq ft supported · box says 426 sq ft
The box says 426 sq ft. By the winter load calculation this output supports about 123 sq ft — the claim is 3.5× the room the machine can hold.
Holding 426 sq ft takes about 1.73 gal/day, which drains this 1.47-gallon tank in roughly 20 hr — against the 70 hours HoMedics advertises, which is measured at the lowest setting.
What a year costs
HoMedics demineralisation cartridges run about $15 a pair and are changed every month or two in season. Electricity assumes the rated 30 W for 12 hours a day across a 150-day heating season at 16¢ per kilowatt-hour.

A claim the maker makes
HoMedics says the tank uses an antimicrobial treatment to inhibit growth on tank surfaces. 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
- Demineralisation cartridge included
- Digital humidistat with auto mode
- 1.47-gallon tank, 70-hour claim on low
- Top fill
- Tower footprint
- Aroma pad tray
- Clean reminder
- 17-18 dBA published
Pros
- Demineralisation cartridge and a real humidistat together at $100 is good value
- Tower shape takes almost no floor area for the water it holds
- The 426 sq ft claim is at least specific enough to look calculated rather than invented
- Filter reminder actually prompts the cartridge change, which is otherwise easy to forget
Cons
- About half a gallon a day at the 70-hour setting - the runtime headline and the coverage headline are very far apart
- Cartridges every month or two at roughly $7.50 each
- The tall narrow tank is hard to clean inside despite the top fill
- No app; the controls are a humidity display, three mist settings, a night-light and an auto-off timer

One 1.38-gallon top-fill tank, warm and cool mist, a demineralisation cartridge in the box, a humidistat and an eighty-five-hour low-setting claim - one of the longest numbers in this catalog, and the one that best illustrates why the number is nearly meaningless. Eighty-five hours from 1.38 gallons is 0.39 gallons a day, about a fifth of what the 521 sq ft printed alongside it would require. HoMedics also prints 21-23 dBA for it, which with the cartridge puts it among the quiet, dust-free units here, and adds an eight-hour auto-off timer.

Levoit
Levoit Classic 300S
Sixty hours of runtime and 505 square feet cannot both be true at once, and the Classic 300S is the clearest illustration of that in the whole catalog. Drain a 6-litre tank over the advertised 60 hours and the unit is putting out about 0.63 gallons a day, which is bedroom-sized. Hold 505 square feet at 40% and it needs roughly 2 gallons a day, which empties that same tank in under 19 hours. Both numbers come off Levoit's own spec sheet; only the setting changes. What you actually get for $80 is a competent, genuinely quiet ultrasonic for one room, with top filling, a real humidity sensor, an auto mode that targets 40-50%, and app control that owners either use constantly or never touch again. It is an ultrasonic with no demineralisation media, so hard tap water becomes white dust on the nightstand, and the tank wants weekly cleaning or it turns pink.

Objecto
Objecto H7 Hybrid
Sold through West Elm and QVC rather than a hardware aisle, which tells you what it is optimised for - a slim tower in a walnut-and-white finish that looks like a speaker. Despite the "Hybrid" in its name it is a cool-mist ultrasonic with no heater - Objecto's own spec reads "Ultrasonic, Cool Mist" - and while the four mist levels are real, a 2.4-litre tank is the smallest of anything here claiming 650 square feet, and twenty-two hours of runtime from it works out to under 0.7 gallons a day. Holding the room it claims would empty the tank in under six hours. Buy it because you want that object on that table; the arithmetic is not the reason.
