Ah, the under-sink filter. This is the moment you realize you’re a real adult. You’re drilling holes in your countertop and using words like “plumbing torque.”
A decent under-sink system (like a reverse osmosis unit or a simple carbon block) will set you back $100 to $300. Installation? If you are not handy, expect to pay a plumber another $100 to $200. Or, you could just watch a YouTube video and curse your landlord’s cheap pipes for four hours.
Replacement filters run $30 to $100 a year. Compared to buying bottled water? It’s a steal. Imagine saving enough money in two years to buy yourself a single, very nice pair of jeans. That’s the financial vibe we’re going for here.
The Whole House System – The “I’ve Got Money and I Hate Hard Water” Flex
This is the Ferrari of water filters. Whole house systems filter every single drop of water that enters your home. Your shower, your toilet, your kitchen sink, your dog’s water bowl. All of it.
Expect to pay $1,000 to $3,000 for the equipment. Installation is a different beast, often costing another $500 to $1,500. This is not a decision you make after a glass of cheap wine. This is a decision you make after researching water hardness for three months.
How Much Do Home Water Filtration Systems Cost? {Price Chart}
You’ll never have to scrub a water spot off a glass again. Your skin will feel like a dolphin’s. But your wallet will feel like it just ran a marathon. It’s a trade-off.
