Our take on the BCOOSS Humidifier for Room Small Cool Mist Top Fill Air Humidifier and Vaporizers for Home, 1.5L

The BCOOSS 1.5L is a small ultrasonic cool-mist humidifier with a top-fill tank, a 360-degree rotating nozzle, two mist modes and a night light. It runs on USB power and shuts off automatically when the tank empties, and it has an aromatherapy tray for water-soluble oils. Its rated coverage is only about 25 square feet, so it suits a desk or bedside rather than a full room. At $11.27 at Walmart as of November 3, 2026, it is a budget buy, and it is the only new price listed.

Questions and answers

Is the BCOOSS 1.5L humidifier worth it?
At $11.27 at Walmart as of November 3, 2026, it is a low-cost way to add mist to a desk or nightstand. Do not expect it to humidify a full bedroom; its rated coverage is about 25 square feet.
How long does the tank last?
Continuous mode shuts off after 4 hours and intermittent mode after 6 hours, so expect to refill roughly once or twice a day. The 1.5L tank is small for anything beyond a bedside.
Does it need a filter or special water?
It is listed as filtered, and the aromatherapy tray only takes water-soluble essential oils. Distilled water will cut down on white dust from minerals.
Can I use it with a power bank?
Yes. It runs on USB power, so a power bank or laptop USB port works. Output is modest because of the USB supply.
Is it loud at night?
It is described as near-silent, and ultrasonic units of this size are usually quiet enough for a bedroom. The night light can be turned on alone with a long press.
When is it cheapest?
Small humidifiers like this usually drop during fall and winter humidifier sales and around Black Friday. Check the price history before buying outside those windows.
Where is the BCOOSS Humidifier for Room Small Cool Mist Top Fill Air Humidifier and Vaporizers for Home, 1.5L cheapest?
