If you’re handy with a wrench and enjoy reading instructions (you psychopath), you can install an under-sink system yourself. That costs zero dollars extra. Most countertop models are even easier—just plug and play, like a video game console for your water.

Here’s the part that makes people gasp like they saw a ghost. RO systems need replacement filters. Every 6 to 12 months, you’ll drop $50 to $150 on new filters. Think of it as a subscription fee for clean water—but without the awkward phone call to cancel.

Also, RO systems waste water. For every gallon of filtered water, they dump 3 to 4 gallons down the drain. Yes, it’s a bit wasteful. But newer models (like “permeate pump” systems) cut that waste in half. Spend an extra $50 to $100 upfront to save gallons later. Your inner environmentalist will high-five you.
