Identifying water hardness and selecting correct filtration is a hardware problem in Home & DIY. It has a heat score of 24 (demand) and competition score of 42 (existing solutions), creating an opportunity score of 34.7.
Homeowners don't know if they have hard water or what's causing taste/smell issues, so they buy generic pitcher filters or wrong whole-house systems. No simple diagnostic exists, leading to ineffective solutions and wasted money on unsuitable treatments.
