GeneralAire 990-13 FAQ

Why can't I wash and reuse the 990-13 evaporator pad?

The pad is treated with a specialized absorbent coating that evenly distributes water. Attempting to wash or scrub the pad strips away this coating and crushes the aluminum mesh, permanently eliminating its ability to evaporate water into your home.

How often should I replace the GeneralAire 990-13 pad?

Replace the pad at least once per heating season, ideally in the fall before starting your furnace. If your home has hard water or high humidifier usage, inspect and replace the pad more frequently to prevent scale from choking system airflow.

Is this the same part as GeneralAire 7002?

Yes. The 990-13 evaporator pad is also cataloged and commonly referred to as part number 7002.

What is the purpose of the wire frame on this pad?

The heavy wire frame provides added structural stability, keeping the media filter firmly aligned in the humidifier housing under continuous furnace airflow.
