WHOLE HOME UV
Filters do a great job of removing what you can see but bacteria and microorganisms are a different story. That's where UV purification comes in.
Our whole-home ultraviolet water purifier uses UV light to neutralize harmful bacteria and microorganisms before they ever reach your tap no chemicals, no byproducts, just clean, safe water flowing through every line in your home.
It's designed to work quietly in the background, treating water as it enters your system so you never have to think about it. And because it integrates seamlessly with whole-home filtration systems, it's an easy and effective way to add an extra layer of protection to whatever setup you already have.
We even include a spare UV bulb so when maintenance time comes, you're already covered no downtime, no scrambling, no gap in protection.
It's the kind of peace of mind that's hard to put a price on.

PRE SEDIMENT FILTER
Think of it as the first line of defense for your home's water.
Before water ever reaches your pipes, fixtures, or any other filtration equipment, our whole-home pre-sediment filter is already on the job. It catches dirt, sand, rust, and other particles that would otherwise work their way through your system over time.
It's a simple concept with a big payoff. By stopping the buildup before it starts, everything downstream runs cleaner and lasts longer. Your plumbing, your fixtures, and any other water treatment equipment you have in place all benefit. Whether you're on city water or a well, it's a smart first step that protects everything that comes after it.
Not the flashiest part of a water treatment system, but one of the most important ones.

WHAT OUR CLIENTS SAY
FREQUENTLY ASKED QUESTIONS
Do I really need a water filtration system in San Diego?
Yes. San Diego is known for having very hard water, which means high levels of calcium and minerals. Over time this can cause scale buildup in pipes, water heaters, dishwashers, and other appliances. A whole house water filtration and softening system helps protect your plumbing, improve water quality, and extend the life of your appliances.
What is the difference between a water softener and a water filtration system?
A water softener removes hardness minerals like calcium and magnesium that cause scale buildup and white residue.
A water filtration system removes contaminants such as chlorine, sediment, and chemicals that affect taste, odor, and water quality.
Most San Diego homes benefit from both systems working together to provide cleaner, better-feeling water throughout the home.
What does a reverse osmosis system do?
Reverse osmosis systems provide highly purified drinking water by removing contaminants, dissolved solids, and impurities at the molecular level. These systems are typically installed under the kitchen sink and provide bottled-water quality drinking water directly from your tap.
How long does installation take?
Most water softener or filtration system installations take 2–4 hours depending on your home’s plumbing setup. Our professional technicians handle the entire process so you can start enjoying cleaner water the same day.
Are your water systems made in the USA?
Yes. Honest Water Co installs high-quality American-made water systems designed for long-term performance and reliability. Our equipment is built to handle San Diego’s hard water conditions while delivering consistent filtration and softening.
Do your systems come with a warranty?
Absolutely. We stand behind our equipment with a lifetime warranty, giving homeowners peace of mind that their water system is protected for years to come.
Will a water softener help with dry skin and hair?
Yes. Hard water minerals can strip moisture from skin and hair. Many homeowners notice softer skin, smoother hair, and reduced soap residue after installing a water softener.
Does filtration improve drinking water taste?
Yes. Whole house filtration removes chlorine and other impurities that affect taste and odor. When combined with a reverse osmosis system, you can enjoy clean, crisp drinking water directly from your tap.
How do I know if my home has hard water?
Common signs of hard water include:
• white spots on dishes and glassware
• soap that doesn’t lather well
• dry skin and hair
• scale buildup on faucets
• reduced appliance efficiency
We offer free water testing to determine your home’s water quality.
How much does a whole house water system cost?
The cost varies depending on the size of your home and the type of system installed. At Honest Water Co, we provide free consultations and water testing to recommend the best solution for your home and budget.
