Find top rated water treatment & purification system installers and replacers in your area

A whole-house water filtration system is ideal if you want all the water in your home to be filtered, improving water quality and protecting your plumbing. This system can enhance your home's value. If you only need filtered water for drinking or cooking, a point-of-use filter might be a suitable alternative. Each filtration option is designed to remove specific contaminants.

Maintaining your whole‑house water filtration system is essential for uninterrupted performance and clean water. The annual expense, which ranges between $50 and $300, covers filter replacements, complete system inspections, and any required repair work. Regular maintenance keeps the system operating at peak efficiency and guarantees the highest water quality for every home use.

Installing a whole‑house water filtration system is a streamlined process that a professional can complete in one day. Multistage systems require additional time to secure proper plumbing connections and calibrate the system accurately. In contrast, point‑of‑use filters are installed within a few hours, ensuring efficient and precise integration in your home.

Most whole-house filtration systems last 10 to 20 years with proper care. Reverse osmosis units typically serve 10 to 15 years, while water distillers can exceed two decades. Lifespan depends on build quality, water chemistry, and whether filters, lamps, or membranes are changed on schedule. Regular professional inspections help you catch minor issues before they shorten the system’s life. Budget for planned component replacements to reach the upper end of that range.

Fast clogging usually points to high sediment levels, heavy water use, or both. When more dirt and minerals flow through the system, filters load up sooner and performance drops. Schedule a water test to confirm what’s in your supply, add a sediment pre-filter if needed, and follow the manufacturer’s replacement timeline to keep water pressure and quality where they belong.
