It draws water up through its filter media and allows a fan to evaporate moisture into the air, maintaining indoor humidity levels during heating season. The HDC311 uses Trapmax technology to capture mineral deposits and airborne particulates before they circulate through the living space. This filter is sold in a pack of four, making it practical for technicians and service professionals who perform routine humidifier maintenance across multiple units or across multiple service intervals.\u003c\/p\u003e\u003cp\u003eThis wick filter is suited for residential evaporative humidifiers where periodic filter replacement is part of scheduled maintenance.
