The CARRIER p110-1045 is a replacement humidifier evaporator pad designed for whole-home bypass and flow-through humidifiers installed on central forced-air heating systems. The pad measures 9.5 inches by 10 inches and fits directly into the humidifier water panel frame. It absorbs and distributes water evenly across its surface so that conditioned airflow picks up moisture before being delivered throughout the living space. Licensed HVAC technicians and experienced service pros install this pad as part of routine humidifier maintenance, typically at the start of each heating season or when the existing pad shows mineral scale buildup that restricts airflow or reduces moisture output.
This humidifier pad is intended for residential central HVAC applications where a whole-home humidifier is mounted on the supply or return plenum of a gas or electric forced-air system. The 9.5-inch by 10-inch format matches a specific water panel frame size common to Carrier-branded humidifier units. Regular pad replacement maintains rated moisture output and prevents mineral deposits from degrading indoor air quality or damaging the humidifier cabinet and solenoid valve over time.
Designed as an OEM-style replacement humidifier pad for Carrier whole-home bypass and flow-through humidifier units requiring a 9.5-inch by 10-inch water panel.
Humidifier pad replacement is a routine HVAC maintenance task typically performed by a licensed HVAC technician. Before servicing, shut off the humidifier water supply and disconnect power to the humidifier unit at the equipment disconnect or thermostat control wiring. Slide the old pad out of the frame, discard it, and seat the new pad firmly before reassembling the water panel and restoring water flow and power. Inspect the solenoid valve, distribution tray, and drain line for scale or blockage at the same service interval.
