Product review (5 stars): ... Aprilaire and the winter temperatures made it feel more like Sahara air than April
I was having trouble with my Aprilaire and the winter temperatures made it feel more like Sahara air than April.
I replaced the filter but noticed the amount of calcium build up in the lower tray as well as the plastic tube.
The instructions on YouTube were more complicated
 than my single woman brain could grasp.
Instead, I simply replaced the filter and lower tray. I've not decided to tackle the rest and know my humidity will not be optimized unless I do, however, the humidity level is no longer an issue with the weather the way it is. I am happy just knowing the filter and lower tray are brand new. I would purchase again.
