Review on 💧 AO Smith Whole House Water Filter System - High Performance Carbon Filtration, NSF Certified - Removes 97% Chlorine - 600,000 Gl, 6yr Lifespan - AO-WH-Filter by Sara Adams

I have an AO Smith 40,000 grain softener with potassium instead of sodium, an AO Smith whole house carbon filter and this air conditioner. Hardness is about 28 GPG, so my fabric softener replaces about 25 GPG with potassium, allowing about 3 GPG of vital minerals to flow through the conditioner and then polish through a charcoal filter. I installed everything myself and am not a plumber, so not much to say about toilet feng shui, but our water is as good as any bottle and our dishes look spotless.
