HoMedics
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. 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 $80, which is not on offer from most rivals at this price.
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.

- 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
Pros
- Demineralisation cartridge and a real humidistat together at $80 is genuinely 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 or scheduling, so the filter reminder is the only thing it will ever tell you
What owners say
Summarised from owner discussions and long-form owner reviews. Nobody here has used this unit.
Good value on paper and an odd one in practice. The cartridge-plus-humidistat combination at this price is genuinely uncommon, and HoMedics is the only maker here actively telling owners to use tap water rather than distilled — which makes sense given the cartridge, and confuses people who have read the opposite advice everywhere else. Its troubleshooting table even lists distilled water as a possible cause of faults.
The fault owners report is worth checking for early. Several describe the unit producing visible mist only on its continuously-on setting and appearing to do nothing when a humidity percentage is selected, with at least one owner seeing the same behaviour on two separate HoMedics units. It may be the humidistat reading the room as already satisfied, but it presents as a dead machine, and it is worth testing inside the return window.
What owners like
- A demineralisation cartridge and a real humidistat together at this price is genuinely good value
- The tower footprint 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 rounded up
- HoMedics is unusual in this catalog for telling owners to use tap water rather than distilled — the cartridge is what makes that advice coherent
Common complaints
- Owners report a recurring fault where the unit only produces visible mist on its continuous setting and appears to do nothing when a humidity target is selected — one owner has had the same behaviour on two HoMedics units
- The tap-water instruction confuses buyers who have read the usual distilled-water advice everywhere else, and the manual lists distilled water as a possible cause of faults
- About half a gallon a day at the 70-hour setting, which is a long way from what its coverage figure implies
- The tall narrow tank is hard to clean inside despite the top fill
Questions owners ask
Should I really use tap water?
Why is there no visible mist when I set a humidity target?
Does it really cover 426 sq ft?
HoMedics TotalComfort Deluxe, head to head
Looked at alongside it

Two 3.8-litre tanks rather than one big one, which makes the refill a pair of manageable trips and means you can run it on a single tank overnight. Warm and cool mist, demineralisation cartridges, a humidistat and an eighty-five-hour low-setting claim - the longest number 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, roughly a tenth of what the 521 sq ft printed alongside it would require.

Pure Enrichment
Pure Enrichment HUME
Sold on being easy to clean - a wide 3.5-litre tank you can get a whole hand into, which is a bigger deal than it sounds given that the narrow-necked tank is why most cheap humidifiers end up growing something. Fifty hours on the low setting, no filters, and no room-size claim printed anywhere, which after forty-odd entries in this catalog reads as restraint rather than an omission. What you give up for the wide mouth is a sensor: there is no humidistat, so it runs at the level you set until it is empty, and in a small closed room that is how windows end up wet.

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 $72 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.
