Fan coil units are not only responsible for indoor temperature regulation but also play an important role in improving indoor air quality. Most fan coil units are equipped with high-efficiency air filters at the air inlet, which can effectively capture dust, pollen, pet dander, and other particulate pollutants in the air.
As the unit circulates indoor air continuously, it passes through the filter repeatedly, gradually reducing the concentration of suspended particles in the air. For users with allergies or respiratory sensitivity, this feature can significantly reduce the risk of exposure to allergens. Some advanced models also support optional filter upgrades, such as antibacterial filters or HEPA filters, which can further inhibit the growth of bacteria and mold, and even block fine particles like PM2.5.
Combined with regular filter cleaning or replacement, fan coil units can maintain a cleaner and healthier indoor air environment, especially in enclosed spaces such as offices and homes where natural ventilation is limited.
