I bought this when I purchased my new filter for our whole home humidifier. We have well water and seems like the filter gets slimy super fast so I figured with the heck it's worth a try.

Well let me tell you it's been amazing we have been using a capful everything we fill the water and it's been almost a month and guess what.. No slime!  Definitely worth the small amount of money because filters are not cheap.
