GeneralAireGA23 Vapor Pad, 1.25 x 14" x 12

This GA23 pad is the correct replacement for a GeneralAire 1099LHS "legacy" flow-through humidifier. Unhelpfully the owner's manual tells you it's a 1099-20 (on p3) or a GA19 (on p7 and p8), meanwhile the separate (single-page) parts drawing says GA23. (I downloaded both documents as PDFs from GeneralAire's website.) I very nearly bought a GA19 before I realized my mistake. GA19 is too small. Measure your existing vapor pad if you don't believe me. By my measurements the GA23 is approx. 11.75 x 14 x 1.5 inches.

Loved finding a GeneralAire filter for this price.

The pack is very ordinary but certainly the filter itself will meet our expectations.

Perfect fit

I was surprised with the price and think they my be better the the original that came with the unit

Perfect fit and less than five minutes to pull out the old crusty pad and drop the new one in place!

Fit perfectly, easy to install

This vapor pad works with my GeneralAire 1099LHS humidifier like expected.

Replacement vapor pad for GeneralAire 1099LHS model humidifier. It can be hard to find exact same model at local building materials stores, they tend to have vapor pads with built in metal frame.If you have 1099LHS, this is the vapor pad to get.

The pads fit nicely in my humidifier. the only suggestion would be to have the edges somehow treated to slide in easier into the plastic trim.
