Fancoil filters are filtering units used in HVAC (Heating, Ventilation and Air Conditioning) systems, commonly known as fancoil units. These filters are designed to clean airflow and improve indoor air quality. Fancoil filters are generally used at air inlets and outlets, inside fancoil units or in air ducts to retain particles, dust, pollen and other pollutants in the air. These filters can often have various filtration levels and efficiency classes. Fan coil filters are an important piece of HVAC equipment that requires regular maintenance. Cleaning or replacing filters regularly prevents airflow from being blocked and filtering efficiency reduced. Additionally, regular maintenance of fan coil filters ensures longer lifespan of HVAC systems and maintains indoor air quality. Fan coil filters often have special designs that optimize air flow and can be easily integrated into fan coil units. These filters are commonly used in office buildings, hotels, hospitals, shopping malls and other commercial and industrial applications.
