Frequently asked

What filter/pad fits a Generalaire 1042-l humidifier?

The Generalaire 1042-l uses the 990-13 (Generalaire 990-13 Evaporator Pad), a furnace/whole-house water panel.

Is the 990-13 a wick or a furnace pad?

The 990-13 is a furnace/whole-house humidifier water panel, not a portable-unit wick.

How often should I replace the 990-13?

We don't have a manufacturer-listed replacement interval for the 990-13 - a common default is once per humidifying season, or sooner if it's visibly scaled or discolored.

Should I buy the OEM filter or an aftermarket one?

The genuine Generalaire 990-13 is the safe, exact-fit choice. A cheaper aftermarket wick or pad can fit the same slot too - check reviews for real-world fit and how well it wicks water before buying, since humidifier filters aren't independently certified the way NSF-listed water filters are.
