Cost guide

How much does a reverse osmosis system cost?

Reverse osmosis cost depends on the system type, what you need it to remove, your water's hardness and pressure, and filter upkeep. Get an exact price after a free analysis.

WÜDR doesn't publish price ranges. A range that covers every home is too wide to be useful, and a price for the wrong system is worse than no price. Instead, we look at your water first, recommend the system that fits, and then show you its price.

What drives the price

  1. What it needs to remove. PFAS, lead, nitrate, and arsenic claims are certified separately under NSF/ANSI 58; a system certified for your contaminant matters more than the number of stages[1].
  2. Tank or tankless. Tankless systems with a pump save space and deliver faster flow; tank systems are simpler.
  3. Water pressure. Low household pressure may call for a booster pump.
  4. Hardness and iron. Hard or iron-rich water shortens membrane life, so a softener or pre-treatment may be recommended. See hard water.
  5. Installation. Sink space, a drain connection, a faucet hole, and optional lines to the refrigerator or ice maker.
  6. Upkeep. Pre-filters, the membrane, and post-filters on a schedule.

Common questions

Is reverse osmosis worth it on city water?

It depends on your report. It's most useful if your utility shows PFAS, your home may have lead plumbing, or you buy a lot of bottled water.
