About Safe Home Drink

An education project for families in Oceanside, Vista and San Marcos who want straight answers about their drinking water.

Why this site exists

Homeowners get a lot of water advice from people selling something: "free water tests," expensive whole-house systems, and softeners pitched as drinking-water safety. This site explains what those products do and don't do, shows the real numbers, and points to simple, low-cost options that work.

Who runs it

Safe Home Drink is run by Raymundo Razon Abad, a civil engineer (licensed in the Philippines) and independent researcher who has worked in reverse osmosis water purification for 35 years, most of them in Southern California through Pure Water Center of SoCal. After graduating from Mapúa Institute of Technology, he spent two years as a quality-control inspector for the high-rise water plumbing at Marina Centre Square in Singapore. His research on dedicated drinking-water lines and short-chain PFAS is shared openly on the Studies page.

How we choose products

Products on Our picks are chosen on one test: does it actually do what it claims? For reverse osmosis units, that means a verifiable NSF/ANSI 58 certification. Prices and certifications are checked and dated. If we ever earn a commission from a link, the page says so clearly.
