Hisense has introduced the Deep Sleep Fresh Air Conditioner X3 Plus split system with an interesting feature – the novelty can not only cool but also supply fresh air to the room. In addition, the device is notable for its low noise level during operation and high energy efficiency.
Hisense X3 Plus Specifications
Hisense 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%.
Hisense 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.

Hisense 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.
