HQRP - Humidifier Wick Filter Replacement for Honeywell HAC-504AW HCM-350W HCM-350 Series Filter A

Humidifier wick filter replacement designed to restore efficient evaporative humidifier performance by delivering clean, fresh moisture while helping trap mineral deposits, dust, and dirt before they spread through your air. The reinforced outer layer supports extended filter life and consistent wicking, while the pre-filter layer helps capture larger airborne particles as air passes through the filter and can help reduce household odors. Compatible with Honeywell humidifier models HCM-300, HCM-300T, HCM-305T, HCM-310T, HCM-315T, HCM-350, HCM-350B, HCM-350W, HCM-350B-CST, HCM450BCST, HCM-500, HCM-530, HCM-535, HCM-535-20, HCM-540, HCM-550, HCM-550-19, HCM-551, HCM-560, HCM-600, HCM-630, HCM-631, HCM-632, HCM-632TG, HCM-635, HCM-640BW, HCM-645, HCM-646, HCM-650, HCM-700, HCM-710, HCM-1000, HCM-1000C, HCM-1010, HCM-2000, HCM-2000C, HCM-2001, HCM-2002, HCM-2020, HCM-2050, HCM-2051, HCM2052, HEV-312, HEV-355, ECM-250i / ECM250i, and Radio Shack 63-1508.
