A cheap, very quiet small-room humidifier that three expert outlets recommend for value, but its narrow tank is hard to clean, it needs refilling about daily, and Amazon owners rate its reliability negatively.
Top complaints
- Narrow tank is hard to clean; mold reports
Good Housekeeping found it not the easiest to clean because of the narrow tank opening (a brush is included). Cleaning is mixed on Amazon, where some owners say it is almost impossible to clean. A Walmart 1-star reviewer says mildew builds up inside the tank, which can't be fully opened.
- Dead on arrival or quits early
Reliability is a negative aspect on Amazon, citing units that stopped working after a week or won't turn on. Several low-star Walmart reviews describe units with no mist, units that arrived broken, or tanks that leaked.
- Small tank, frequent refills, small rooms only
CNN had to refill it every 18-20 hours on low and wouldn't use it in larger rooms. Good Housekeeping rates it up to 12 hours on high. HGTV lists frequent refills as a con.
- No humidity sensor; gurgles when low; bright display
CNN notes there is no built-in hygrometer, so it can't avoid over-humidifying. HGTV found it makes a loud water-cooler sound when the water runs low, and its display stays bright even with the night light off.

What owners love
- Very quiet
CNN says it produces virtually no noise; Good Housekeeping praises its ultra-quiet operation; quiet operation is the top Amazon positive.
- Capable for a small bedroom
CNN measured roughly +7-9% humidity within an hour on high in a small bedroom.
Source: CNN Underscored - Cheap and simple
Good Housekeeping's best value at about half the price of most; one-button control and auto shut-off.

What experts say
- Good Housekeeping: Best value: quiet, compact and simple; the con is that the small tank hole makes cleaning harder.
- CNN Underscored: Best for bedrooms: virtually silent and capable in small rooms, but it has no hygrometer, a small tank and only two mist levels.
- HGTV: Best value (updated 2026-09-08); cons are loud gurgling when water runs low, a bright display and frequent refills.
