Our take on the Qholemyo 800ml Small Humidifier USB Oil Diffuser

The Qholemyo 800ml is a small corded USB evaporative humidifier that doubles as an oil diffuser. It runs up to 16 hours per fill and is rated at 35 dB, so it suits a desk or nightstand rather than a whole room. Its coverage is listed at about 1 sq ft, which is very small. At $12.18 at Walmart as of November 6, 2026, it is a budget buy with only one store pricing it new, so there is no recent range to compare against.

Questions and answers

How much area does it cover?
The listing gives a coverage area of about 1 sq ft. Treat it as a personal humidifier for a desk or bedside, not a room humidifier.
How long does one fill last?
Run time is listed at up to 16 hours. Actual time depends on the mist setting and room conditions.
Can I use essential oils in it?
Yes. It is sold as a humidifier and oil diffuser, so it can add scent as well as moisture.
Is it safe to leave running overnight?
It is not NRTL listed, so there is no third-party safety certification. Run it on a stable surface and unplug it when not in use.
Does it need a power outlet?
Yes. It is corded electric with USB power, so it needs a USB outlet or adapter and does not run on batteries.
Is $12.18 a good price?
Only one store prices it new at $12.18 as of November 6, 2026, so there is little price history to judge against. At that price it is a low-cost entry.
Where is the Qholemyo 800ml Small Humidifier USB Oil Diffuser cheapest?
At Walmart, for $12.18, as of our latest check.
