  • My humidifier works like new again

    Posted by: dudzcivic


    Fast delivery, clear instruction and all parts fits well. We bought a house with Aprilaire 560 installed and it seems the previous owner didn't maintain it properly. Water supply pipe that goes to unit was clogged and the water panel needs to be replaced. With this kit the humidifier works like new again.

    Good kit. Got our system up and running

  • Fixed the problem caused by crappy 3rd party filters

    Posted by: Mike S.


    Used some crappy cardboard filters (that claimed to be from Aprilaire) that clogged the system and burned out the pump motors. With the kit and Aprilaire's filters (legit ones/bought from Aprilaire) all is now great!

    It is so easy to replace a water panel. Even a clutz should be able to do it, unless of course they can't tie their own shoes. Replace it annually!

  • Great Quality!!

    The kit was shipped very promptly, and my son-in-law, who had located your web site, was able to install it quickly. We haven't yet turned it on but will do so this weekend. So far, no problems.

    I discovered the kit when looking on the web site to order just new media. It arrived promptly, was easy to install and has my old 560 working like new. It corrected a restricted water flow problem and was well worth the cost.

  • Don't bother with the maint kit for 560.

    Posted by: Rocky


    We've lived in this house for a couple years and I don't know when the system was last serviced or if it ever was. I got the maint kit when I finally got around to servicing the system. Don't bother buying the maint kit, just buy a new water panel. There is a water panel and a few other parts included in the kit. The only thing that has a chance of needing replacement is the water orifice and strainer (mine were OK). Just about everything can be reused from your old system.

  • Replacement Kit was a cinch!

    My filter hadn't been replaced for nearly 15 years so I ordered the entire maintenance kit and did it myself. Instructions were clear and it took me less than 10 minutes!

  • new parts for humidifier

    I am thrilled with the new parts. I didn't realize what a difference it would make. My old parts were moldy and I could smell the mold throughout the house. I even had the hoses changed. What a difference.

  • Aprilaire Maintenance Kit

    I ordered a maintenance kit for my Aprilaire 560. The kit arrived quickly and was easily installed. Unfortunately, the kit did not resolve my underlying problem - excess flow. Subsequent calls (all received by friendly and helpful people) resulted in a home test of the flow and ultimately a suggestion to order a subsequent part (which was part of the original maintenance kit. Overall experience was generally good except that problem still exists.

    Worked just fine; no problems; just what I needed. We have hard H2O & the old stuff was totally clogged. Got the humidity gauege at the same time & humidity during this winter is just where it needs to be. No static; life inside is good. Thanks.

    Easy to order. Order promptly filled.

  • Very Convenient

    Posted by: All Thumbs


    No need to figure out a bunch of part numbers, its all there in one convenient kit. Much easier than soaking parts for days and now it looks like new.

  • exactly as needed

    I waited too long to perform this simple maintenance. It only takes 20 minutes or so and it greatly improves the performance of your unit. Depending on your water, you may be able to do this maintenance every 2 or 3 years, but consider doing it each year.

    Only other thing I needed was a replacement condensate pump.

    I purchased the kit noted above, but since this was for my new home, and the old parts were not in the unit I was having a problem with connecting the water supply line to the top of the pad. I tried looking on the web site but was not able to find anything on this connection. Please let me know were I could find these directions.
