How long does one bottle last?

At the high setting of 120 cc/hour, the 12.85 oz (380 ml) bottle lasts roughly three hours. Expect longer on the low setting.

Does it need distilled water?

Ultrasonic humidifiers can leave white dust with hard tap water. Distilled or filtered water keeps the mist and the unit cleaner.

Can I use it in another country?

Yes. The included UL-approved adapter accepts 100-240V at 50/60Hz, so it works on most overseas outlets with a plug adapter.

Does it shut off when the bottle is empty?

The listed features do not include an auto shutoff or empty-tank sensor, so turn it off when the bottle runs low.

How big a room will it humidify?

It is a personal humidifier. It is meant for a desk, nightstand or small nursery, not a full bedroom or living room.

Is $34.37 a good price?

Walmart is the only store listing it new at $34.37 as of November 6, 2026, so there is no competing price to compare. Check the price history before buying if you are not in a hurry.

Our take on the SPT Sunpentown SU-1054 Personal Humidifier with Water Bottle

The SPT Sunpentown SU-1054 is a battery-free personal ultrasonic humidifier that runs off its own 12.85 oz water bottle and a 100-240V AC adapter. It puts out cool mist at two settings up to 120 cc/hour and is rated at 24.98 dB on low, so it suits a desk, a nightstand or a hotel room. The unit itself is small (4.53 x 2.87 x 3 inches) and weighs about half a pound. At $34.37 at Walmart as of November 6, 2026, it is the only new price listed, so there is no recent range to compare against.
