Fits Aprilaire 224 perfectly

Mark E.β€”January 11, 2019

After living in my new house for over a year we discovered the humidifier had been off, so we turned it on to help fight the dry winter air. A few hours later we noticed water leaking from our older Aprilaire 224 unit. This started the project of me figuring out what the problem was, having to rebuild leaky copper compression fittings at sealing the drainage on the unit itself. Since I had no idea if the previous homeowners did any sort of maintenance on the unit I figured it was long overdue for a new water panel. I ordered this as it’s listed to fit my model 224 and it fit perfectly. Install of the water panel was the easiest part of my unit repair. Now my humidifier is running like a dream and adding needed moisture back into the house. Will repeat buy as the suggested replacement schedule is yearly. Read more

Easy Installation

K. Tanenbaumβ€”February 5, 2024

You'll need to loosen the clips holding the outside of the humidifier to your furnace, probably remove a screw holding the air return to the unit, move the water inlet, open the unit, do not wipe the bottom inside, swap out the filter, and reassemble. Takes a little time in a cramped space behind my furnace. Read more

Worked Perfect For My Special Use

The Honest Critiqueβ€”June 18, 2020

I built a humidifier for my huge humidor using a 6" deep full size restaurant pan and lid. It utilizes three 4" fans and a ultrasonic fogger inside. But I needed a baffle after the fogger and before the exhaust. This "panel" was the perfect size when cut in half. I siliconed some supports in place and now this baffle can be replace in minutes. Now I get humidity and not mist out of my humidifier. Read more
