Let’s do some quick math. A family of four spending $30 a month on bottled water is paying $360 a year. A reverse osmosis system installed for $1,200 pays for itself in about 3.3 years. After that? You’re drinking for free. Well, almost—filter replacements still cost a little. But your wallet does a happy dance.
And if you factor in health benefits (fewer plastic bottles, less chemical ingestion), you’re basically a superhero. Plus, you’ll never have to lug a 24-pack from the store again. Your back will high-five you.
