Custom Whole Home Water Filters and Systems from the San Diego Water Filtration Experts

Better taste, bigger benefits — whole home water filtration keeps your people hydrated, happy, and your house running smoothly.

From Chula Vista to Carlsbad, communities all over our area using untreated San Diego tap water can experience problems throughout the home. It might be the less-than-fresh taste, or dissolved minerals leaving behind residue on fixtures and taxing major appliances, the result is San Diego water that can shorten the lifespan and plumbing, fixtures, while causing expensive problems in and around the home.

The solution? A whole home water filtration system that improves taste and quality, solving water problems before they enter your home. Whole home systems, also known as point-of-entry (POE) water filters, not only enhance water taste, they’re an important part of a more sustainable, energy efficient house.

Water Quality in San Diego

Combining water from the Colorado River, Sacramento River, and the State Water Project, San Diego water requires many chemical and treatment steps to ensure water is safe to drink. And while this process keeps our communities safe, it can sometimes leave the taste, smell, and overall quality of our tap water less than its best.

It’s also not uncommon for San Diego homes to see the stubborn, white buildup on faucets that comes from hard water and the staining or discoloration on sinks and around fixtures from dissolved minerals in tap water. These untreated water problems can not only be unpleasant, they can cause often unnoticed problems in your home, from plumbing and fixtures to major appliances.

FAQ About Culligan® Whole House Filter Systems


1. What are the benefits of the Quadra-Hull® tank?

Culligan’s Quadra-Hull® tank is one of the strongest water tanks available on a water softener. The exclusive four-layer construction of the Quadra-Hull® tank provides more protection than industry standard fiberglass and metal tanks. This design makes them impervious to rust and corrosion and they are UV resistant. Culligan's Quadra-Hull® tanks offer a limited lifetime warranty on the tank and internal components.

2. What is filtered water?

Filtered water typically refers to water that has gone through a filtration process to reduce the amount of iron, hydrogen sulfide, aesthetic chlorine taste or odor, as well as microorganisms such as cryptosporidium and giardia.

Water filtration involves separating mineral particles, like particulates, iron, hydrogen sulfide, or organic matter, from the water molecule (H2O). By passing water through a "filter bed," or "media bed," these granular particles are trapped, allowing the cleaner water to pass through.
