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. Pure Enrichment publishes its output as well as its runtime: up to 300 mL an hour, which is 1.9 gallons a day, twelve hours to a tank on high and fifty on low. That supports about 470 square feet, almost exactly the 475 it prints in its copy, though the spec table on the same page says 270. 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.
The room-size claim, reconciled
468 sq ft supported · box says 475 sq ft
The 475 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 475 sq ft takes about 1.93 gal/day, which drains this 0.92-gallon tank in roughly 11 hr — against the 50 hours Pure Enrichment advertises, which is measured at the lowest setting.
What a year costs
no filter or wick is required; Pure Enrichment sells an optional decalcification cartridge for it ($9.99) and asks for a change every six months. Electricity assumes the rated 25 W for 12 hours a day across a 150-day heating season at 16¢ per kilowatt-hour.
Specifications
Maintenance profile
- Top fill
- Yes
- Replaceable media
- None — nothing to buy
- White dust risk
- Yes — atomises minerals with no demineralisation
Facts, not a score. Which of these matter depends entirely on whether the unit ends up somewhere you will actually clean it.
Features
- Wide-mouth 3.5L tank you can reach inside
- Top fill
- 300 mL/hr published output
- 50-hour claim on low, 12 on high
- No filter required; optional decalcification cartridge
- Auto shut-off
Pros
- The tank opening is the whole point and it works - a hand and a cloth reach every surface
- Its 475 sq ft claim is almost exactly what its published 300 mL/hr supports
- Long runtime on low for a tank this size
Cons
- Still an ultrasonic: nothing in the box stops white dust on hard water unless you add the $9.99 cartridge
- No humidistat and no auto mode; holding a level means switching it off yourself
- No sensor and no app at $50, where the Dreo HM311S has both
- Pure Enrichment prints two room sizes on the same page - 475 sq ft in its copy, 270 in its spec table

Pure Enrichment MistAire XL
Pure Enrichment is unusually straight about runtime: it publishes a range, ten to twenty-four hours depending on the setting, rather than quoting only the flattering end. That one editorial choice tells you more about the machine than any spec - at the high setting a gallon lasts ten hours, which is what a gallon does. It is otherwise an unremarkable and perfectly competent $60 ultrasonic: no filter required, a mist dial, an optional nightlight, auto shut-off. The 500 sq ft claim holds only at the high setting, ten hours to a tank.

Crane
Crane Drop EE-5301
The teardrop shape has been on nursery shelves for over a decade and is probably the most recognisable humidifier in America. A gallon of water, twenty-four hours and no filter required, though Crane sells an optional demineralisation filter (HS-1932) that screws into the tank for hard water. Crane is inconsistent about what it covers: 500 sq ft on its own product page and on retail listings, 250 in its manual. The arithmetic supports the smaller figure: a gallon over 24 hours is about 246 square feet.
246 sq ft supported · box says 500 sq ft
Vicks declines to put a square-foot number on this one, describing it only as a medium-room unit - which, given how the rest of the category behaves, is its own kind of honesty. A 4.5-litre tank running 30 hours works out to just under a gallon a day, the same ballpark as everything else at this price. Dual scent-pad slots, a variable output dial, no filter. The usual ultrasonic caveats apply and the tank neck is narrow enough that cleaning it properly means a bottle brush.
