Think of it like buying a car. You can get a used hatchback or a shiny SUV. A basic whole house system might run you $500 to $1,500 for the equipment alone. That’s for a simple carbon filter setup.
But if you’ve got hard water, iron, or weird smells? You’re looking at $2,000 to $5,000 for the unit. And that’s just the box of magic. Not the labor. Not the extra bits.
Yeah, I know. That’s real money. But stick with me—it’s not all bad news.
What makes the price jump?
Here’s where it gets fun (if you love plumbing). Filter type is the biggest player. A sediment filter is cheap. A reverse osmosis system for the whole house? That’s a whole different beast—think $3,500 to $8,000 for the unit.
Then there’s water softeners. If you have calcium buildup that laughs at your dishwasher, you’ll need one. Add $800 to $2,500 for that, depending on size. And don’t forget UV filters for bacteria—another $500 to $1,500.
Oh, and installation. Unless you’re a DIY hero with a pipe wrench, you’ll pay a plumber. Expect $500 to $2,000. More if your house has weird pipes. (And doesn’t every house have weird pipes?)
