If you are on a private well, the search for the best salt free water softeners for well water is not really about salt at all. It is about iron, manganese, sediment, hydrogen sulfide and flow rate, because those four contaminants decide whether any saltless conditioner will survive a year in your mechanical room. Salt […]

If you want one direct answer before anything else: the best whole house water filters under $500 are the iSpring WGB21B, the iSpring WGB32B and the iSpring WGB22B, because they use industry-standard 10 inch x 4.5 inch and 20 inch x 4.5 inch cartridges that any plumber or any online store sells, they need no […]

It is the reverse osmosis systems for reef tanks setup that quietly turns tap water into something close to chemically empty before your salt ever touches it. I have spent years watching reef […]

If your tap water tastes flat, smells faintly of chlorine, or makes ice that smells like a swimming pool, a reverse osmosis system will fix it for less money than most people expect.
