RO systems aren’t exactly a buy-it-for-life investment. You have to replace the sediment filter, carbon block, and the precious thin-film composite membrane every six to twenty-four months. Those little cartridges add up like subscription boxes you forgot to cancel.
Annual maintenance can hit $100–$200 depending on your water quality. And if you don’t swap them out on schedule? The system becomes a breeding ground for bacteria. Yes—irony of ironies—a machine designed to purify can turn into a swamp.

Cultural reference: It’s like owning a vintage convertible: beautiful when it works, but you’re always wallet-deep in repairs and wondering if it’s worth the curb appeal.
Practical tip: Set a recurring calendar reminder for filter replacement. Also, test your tap water first—if your town’s water is already decent, a $30 carbon filter might do 90% of what RO does for pennies.
