How is this different from a traditional salt-based water softener?

Our systems are salt-free. Catalytic filtration media alters the structure of calcium and magnesium so they can't form hard scale — no salt bags, no chemicals, no sodium added to your water.

Which system is right for my home?

It depends on your home size and water usage. The Elite-15 and Classic-10 work for any home size (up to 6 bathrooms), while the Eco-5 suits medium homes with up to 3 bathrooms. A free water evaluation confirms the best fit.

Do I need to change filters or add salt?

No. All of our systems are cartridge-free and salt-free, with no ongoing filter changes or salt refills required.

What is a salt-free water softener?

A salt-free water softener conditions hard water without adding sodium or chemicals. Instead of stripping out calcium and magnesium with salt, our catalytic media changes the structure of those minerals so they can't form scale — protecting your pipes, appliances, and fixtures while keeping water healthier to drink.

What is cartridge-free water filtration?

Cartridge-free means there are no filter cartridges to buy, track, or replace. Our systems use long-lasting internal filtration media designed to keep working for years without swap-outs, so you get continuous filtration without the recurring cost and hassle of standard cartridge filters.

What is whole house water filtration?

Whole house water filtration treats water at the point it enters your home, so every faucet — kitchen, bathroom, laundry, and outdoor spigots — delivers filtered water. That's different from an under-sink or pitcher filter, which only treats water at a single point of use.

Where Does All the Water Go? A Breakdown of Household Water Use

By Hunter Worsfold Comments Off

Most homeowners don’t think about water usage until the bill shows up. Once you see the numbers, it can be surprising. Everyday appliances quietly add up: toilets can account for nearly 25–30% of indoor use, with older models using 3–5 gallons per flush, while newer high-efficiency units use closer to 1.28 gallons. Showers average about 2.5 gallons per minute, which means a 15-minute shower uses around 38 gallons. Washing machines can range from 15 to 40 gallons per load depending on efficiency, and dishwashers typically use between 4–10 gallons per cycle. Even small habits, like leaving the tap running while brushing your teeth or rinsing dishes, can waste several gallons at a time. It’s rarely one major source. It’s the accumulation of everyday use that drives total consumption.

Where water usage really gets out of control is with leaks. A slow drip from a faucet may seem minor, but it can waste hundreds of gallons per month. A running toilet is one of the worst, potentially losing up to 200 gallons per day without being obvious. These hidden losses are one of the most common reasons homeowners see sudden spikes in their water bill. Locally, water is measured in HCF (hundred cubic feet), where just one unit equals about 748 gallons. In San Diego, water rates are tiered, meaning the more water you use, the higher the cost per unit becomes. That structure is designed to encourage conservation, but it also means that unnoticed inefficiencies, whether from leaks or outdated fixtures, can quickly become expensive.

What’s often overlooked is how water quality plays into overall usage as well. Hard water creates mineral buildup inside pipes, fixtures, and appliances, restricting flow and reducing efficiency over time. Water heaters, in particular, have to work harder when scale builds up, which can lead to longer run times and increased water and energy use. The same applies to washing machines and dishwashers that rely on clean flow to operate efficiently. By addressing water quality before it reaches these systems, you’re not just protecting your plumbing, you’re helping everything in the home run more effectively. Less buildup means better performance, less waste, and more value out of every gallon that comes through your home. Here at One Water Systems, not only do we help with that pesky scale build-up but also ensure the cleanest water coming out of the pipes as well.
