Key Features of Window-style Fresh Air System
High-efficiency H13 HEPA filtration removes 99.97% of airborne particles, including dust, pollen, and formaldehyde, ensuring clean indoor air year-round. Dual-layer activated carbon filter effectively neutralizes odors, smoke, and harmful VOCs, ideal for homes, offices, and newly renovated spaces. Ultra-quiet operation at 22dB, featuring a brushless DC motor for energy-saving performance (15W) and 24/7 continuous airflow. Slim wall-mounted design (320x220x125mm) with tempered glass panel, blending seamlessly into modern interiors while saving space. Smart humidity control maintains optimal 40-60% RH, preventing mold growth in humid climates and dry air in winter. Easy-install window kit (adjustable 20-50cm frame width) requires no ductwork, perfect for apartments and sealed buildings. Real-time PM2.5/CO2 monitoring via built-in sensors with color-coded LED air quality display for instant feedback. Maintenance reminder alerts and tool-free filter replacement (6-12 month lifespan) simplify upkeep. Commercial-grade aluminum alloy housing with IPX4 waterproof rating for durability in coastal or high-humidity areas. Low-temperature operation down to -30°C prevents frosting, making it reliable for year-round use in extreme climates.
