Essick Air Products HDC311 Humidifier Wick Filter 4 Pack

Product Description

The ESSICK AIR PRODUCTS HDC311 is a replacement wick filter designed for evaporative humidifiers. 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.

This wick filter is suited for residential evaporative humidifiers where periodic filter replacement is part of scheduled maintenance. Evaporative humidifier filters typically require replacement one or more times per heating season depending on water hardness and runtime. The HDC311 pack of four provides enough supply for a full year of service or for stocking multiple units at once. Installation is handled by HVAC technicians or knowledgeable homeowners as part of routine humidifier upkeep.

Installation Notes

Wick filter replacement is a standard maintenance task performed by HVAC technicians or qualified service personnel. Before replacing the filter, power down the humidifier and disconnect it from its electrical supply. Remove the old filter carefully to avoid dislodging accumulated mineral deposits into the water reservoir or fan assembly. Follow the humidifier manufacturer's service instructions for proper filter seating and housing reassembly.
