Is $49.96 a good price for this humidifier?

Yes. At $49.96 at Walmart as of November 3, 2026, it is at the low end of its recent price range, and only two stores list it new.

How often do I need to refill it?

The 0.96-gallon tank runs roughly a night to a day on low in a bedroom. Expect more frequent refills on high or in very dry air.

Does it leave white dust?

It uses a demineralization cartridge to reduce white dust from hard water. Replace the cartridge as directed, or use distilled water, to keep residue down.

How big a room will it handle?

It is rated for up to 278 sq. ft., which suits a bedroom or family room. Larger open spaces will need a second unit or a higher-output model.

Is it quiet enough for a nursery?

Yes. It is rated at 31 dB, about as quiet as a soft whisper, and the nightlight helps for nighttime use.

What comes in the box?

The humidifier, a demineralization cartridge and the owner's manual. Check the listing for any included cartridge quantity.

Our take on the Homedics Cool Mist Ultrasonic Top Fill Humidifier

The Homedics Cool Mist Ultrasonic Top Fill Humidifier is a 0.96-gallon ultrasonic humidifier rated for rooms up to 278 sq. ft.

At $49.96 at Walmart as of November 3, 2026, it sits at the low end of what this model typically sells for, so the current price is a good one.
