A fan coil air filter is a crucial component in any air conditioning system. It is designed to filter out particles and pollutants from the air before it is circulated in a room or building. The filter typically consists of a pleated material that captures dust, pollen, and other contaminants as the air is pulled through the unit by the fan. Keeping the fan coil air filter clean and functional is important for maintaining the air quality in your home or office. Over time, the filter can become clogged with debris, reducing the efficiency of the system and potentially causing damage to the unit. Regular cleaning or replacement of the filter is recommended to help prevent respiratory problems and improve the overall health and comfort of occupants.
