Lately I have noticed that when I check the status of the humidifier pad and the furnace filter on the infinity control, the furnace filter seemed to get used up pretty quickly. For the first 3 days it got up to 20%, then the next day it got to 30%. Then out of nowhere i check the next day and it says 0%. Thought maybe it is normal. Went back up to check it a day ago and it was up to 30% again, and as of right now it went back down to 0%, or 10% I dont remember. All while the humidifer pad is steadily increasing normally and now is at 4%. Is there something wrong here or is this normal for the furnace filter usage on the infinity controls to be finniky?

Thanks
