If you don’t have a filter for your shower to turn the hard water soft, I highly recommend you check it out. At our last house we dint have this software, which in Arizona is pretty much a must have. This filter is perfect to get the hardness and all the other crap they put in the water out. My showers have been 10x better since installing and I get out feel all around more clean. Instillation was super easy and took me less than 5 minutes. I have zero complaints about this, and for $30, this is practically a no brainer. I cannot recommend this enough.
