🌡️ Efficient Scale Control Insert for Aprilaire Model 500, 500A, 500M Review

I purchased this product hoping to solve my hard water issues, but unfortunately it did not work as advertised. As my tests showed, it barely made a dent in reducing the scale buildup in my pipes. It's disappointing to spend money on a product that doesn't do what it claims to do. While the product may work for some, it did not work for me.

It's not for the 500 series, it's for the 600 series, now I have a crappy piece of plastic that won't fit in my humidifier! So disappointed that it is labeled for the 500 series and says it will fit any of the three 500 series humidifiers except for the 600 series. Glad I wasted my time buying it needed it this saturday for work, now i have to go out of my way to find what i need!
