Product review (5 stars): Perfect Fit For Aprilaire 560 Humidifier Maintenance
Great maintenance kit for our Aprilaire 560 humidifier. We moved into a new townhouse this summer and I don't think anyone had maintained the humidifier in 15 years. The water pad was moldy and the plastic frame was shredded. Besides that everything was perfect. :)

Everything in this kit fit perfectly. The only tough part was removing the old strainer. I had to detach the solenoid from the humidifier to get better access. Then a bent paper clip sufficed to extract the old strainer and insert the new one. Everything else was a piece of cake. Go for it!
