How Much Does a Reverse Osmosis System Cost
Okay, here’s where the irony kicks in. You might buy a $600 system, but installation is a whole other beast. If you’re not handy with a drill and a wrench, hiring a plumber can add $150 to $400 to your bill. Suddenly, your "budget" system isn’t so budget-friendly anymore.
And then there are the filter replacements—the recurring subscription you didn't sign up for in your head.
