The GermGuardian AC4150 is a small tabletop air purifier built for a child's room. It combines a HEPA filter, a charcoal odor filter and a UV-C light with a star, safari or sea ceiling projector and a rotating night light. Its CADR ratings are modest (dust 60, pollen 68, smoke 35), so it suits a small bedroom rather than a living area. Parents like the night-light and white-noise combination; the trade-off is low cleaning power and filter and bulb upkeep.

Owners of the AC4150 series mostly praise the night light, projector and quiet low speed as a bedtime aid for young children. Criticism centers on limited cleaning power for larger rooms and the cost of replacement filters and bulbs.
The GermGuardian AC4150 is an 11-inch table top air purifier made for a child's room. It combines a HEPA filter, a charcoal filter and UV light in a 4-in-1 design. The HEPA filter captures dust and allergens. The charcoal filter captures odors, such as those from a diaper pail or sports uniforms. The UV light reduces germs.
It also works as a night light and ceiling projector. The night light can rotate from white to green to blue, or stay on one color. With the night light on, you can choose from three projector themes: Twinkle Moon & Stars, Sleepy Safari or Under the Sea.
It has 3 speed settings. Low runs ultra-quiet, and high can be used as soothing white noise.
