Hisense has launched the Deep Sleep Fresh Air Conditioner X3 Plus in the Chinese market. The product is now available for reservation on JD.com at a launch price of 2,499 yuan ($348).
Hisense X3 Plus Specifications
The X3 Plus is a smart air conditioning unit designed to improve indoor air quality and sleep comfort. It is officially recognized as the Global Official Air Conditioner of the 2025 FIFA Club World Cup. The air conditioner supports a large fresh air intake of up to 60m³/h, which allows it to introduce oxygen-rich outdoor air while expelling indoor air pollutants. Hisense claims this system helps reduce indoor CO₂ levels and can extend deep sleep duration by up to 15%.
The X3 Plus features an industry-first dual fresh air vent design. The upper outlet handles air diffusion while the lower outlet introduces fresh air. These two vents work together to create a convection cycle that improves whole-room ventilation. Users can select between a 40m³/h single-vent mode or a 60m³/h dual-vent mode, which requires an additional wall opening.
The unit includes a five-layer filtration system, which combines a HEPA-grade filter, Hi-CAT nano-catalyst antiviral mesh, and layers for removing pollen and other allergens. Hisense says the X3 Plus achieves 99.99% removal rates for H1N1, E. coli, and staph bacteria, and over 97% efficiency for PM0.3 particles. The device also supports an anti-formaldehyde mode using Hisense’s Drying Room 2.0 system, which accelerates the release of VOCs from new furniture using heat and airflow.
The X3 Plus operates as quietly as 16 decibels thanks to a dual-inlet centrifugal fan. It includes a “Deep Sleep Companion” function that uses Z-pattern airflow blades, wave-form diverters, and butterfly flaps to create soft, non-irritating wind. The unit delivers up to 800m³/h airflow, capable of refreshing the room’s air 16 times per hour.
The system features an APF energy efficiency rating of 5.28, placing it above China’s first-class standard. Hisense claims it can reduce electricity consumption by up to 36% with the help of its in-house X-Core inverter chipset.
Hisense has designed the X3 Plus with a matte brushed “Cream White” finish that resists fingerprints and complements a range of interior styles. The outdoor unit uses a Diamond-Class seven-layer anti-rust coating that provides 10 years of corrosion resistance. It can operate in environments ranging from -36°C to 66°C.
The X3 Plus also features a 57°C high-temperature self-cleaning mode, remote control functionality, PTC heating, and dehumidification. Its screen automatically turns off in dark environments for better night-time comfort. The unit is rated at 1.5 horsepower and is suitable for rooms sized between 16 to 24 square meters.
In related news, Hisense recently launched the HT SATURN Home Theater System featuring 7.1.2-channel audio and Devialet sound technology, priced at €999.
