Howard (verified owner) –
I needed to replace the tray and insert on my older Aprilaire 560 humidifier, as the home’s humidity levels were consistently low. After installing the new parts, humidity increased by about 15-20% in a few days I assume due to more even water distribution.
Given the age of the system replacement both parts were difficult to find but Jackson Systems had one in stock and the other on order. Once received I immediately noticed both plastic parts were more solid than OEM. Thanks!
