Triangle water, explained in full

Most water-filtration companies in this market depend on an in-home sales pitch. Their model is to get a tech in your kitchen with a TDS meter and a test kit, demo your tap water against a known clean sample, and pressure-close a $5,000-$8,000 system on the spot. The pitch works on a lot of people. The pitch is also why most homeowners overpay for filtration they don't fully understand.

These guides are our version of telling you what we'd tell a friend over coffee. Specific contaminant levels by utility. Real equipment specs with NSF certifications. Honest pricing math against the alternatives. What filtration does — and what it doesn't.

If you read both and decide the system isn't worth the cost for your situation, we call that a successful piece of content. The Triangle households where filtration actually makes sense will find us anyway.
