The RUIE 2-in-1 is a compact thermoelectric appliance that both dehumidifies and humidifies small rooms up to 269 sq ft. It extracts about 20 oz of moisture per day and holds 108 oz in its tank, with a drain hose for continuous operation. Sleep mode keeps noise under 40 dB and dims the 7-color light. It suits bedrooms, bathrooms, closets and RVs where space is tight and full-size compressor units are overkill. Compared with single-function small dehumidifiers, it adds humidifier mode, but its extraction rate is modest and best for mild dampness rather than heavy moisture.

Keep your home comfortable year-round with this 2 in 1 Humidifier and Dehumidifier Combo. Switch to humidifier mode when the air feels dry, or run dehumidifier mode when the room gets muggy — one compact machine helps you balance the humidity in bedrooms,bathrooms, closets, RVs, and other small spaces up to 269 sq ft. Using energy-efficient thermoelectric cooling — no refrigerant, no compressor, no chemicals — this small dehumidifier quietly pulls moisture from the air and stores it in a 108oz (3.2L) water tank, while the built-in humidifier delivers up to 250mL/h mist output to soothe dry air. The 7-color LED light adds a soft ambient glow, and the dedicated sleep mode dims the light and keeps noise below 40dB for restful nights. When the tank is full, the auto shut-off turns the unit off and a red LED indicator lets you know it’s time to empty it. For continuous drainage, simply connect the included drain hose — perfect for damp basements, bathrooms, and laundry rooms.
