Product review (3 stars): Works fine, "Complete Filtration Services" sent me a non-OEM product
I bought this from "Complete Filtration Services" - they did not send me the Aprilaire product shown in the image, but a non-OEM one by some other company.

It was inexpensive and it seems to be working fine, judging by the humidity monitor in my home, but I was not too pleased with the misleading image showing a different product than the one they actually sent.
