Calcite Neutralization Filter Female Threaded Review

I used this to make well water so mineral free it's like distilled water, more conductive so my steam humidifier works better. I used this on the advice of the manufacturer's tech support. I increase the conductivity and my humidifier works better, although the increase in water conductivity is still not quite up to the humidifier manufacturer's minimum specifications. But the product is not to blame. I suppose I could add a second filter to the line to increase conductivity.
