Product review (5 stars): A kit Aprilaire 560 humidifier owner must buy
After using my Aprilaire 560 humidifier for over 10 years, the feed tube became brittle and had leakage problem. Bought this maintenance kit from Filters-Now, replaced all the brittle plastic parts and feed tube on my humidifier, my humidifier gets a new life now and I expect it to run for another 10 years without problem.  By using this maintenance kit, first, I don't have to buy a new humidifier.  Second, it gives me a saving of at least $150 ($84 for a serviceman visit + parts replacement).
