Why homeowners pick us

Why do San Diego homeowners choose Filter Pros San Diego?

San Diego water is some of the hardest in the country, running 17 to 20+ grains per gallon with chloramine disinfection. Scale builds up in water heaters and fixtures. Chloramine dries skin and hair. We test your actual water first, then build a solution around what we find, not a one-size pitch.

  • We test before we recommend. A technician comes to your home, tests your tap water, and shows you the results. No guessing, no pressure.
  • Medical-grade stainless steel tanks. 304 and 316 stainless, the same alloy used in surgical equipment. No fiberglass, no plastic liners breaking down into your water.
  • Salt-free means nothing to haul. Our PF1025 catalytic media conditions hard water without salt, sodium, or brine discharge. Set it and forget it.
  • A real person on the phone. No offshore dispatch. You talk to a local technician who knows San Diego water, not a script reader.

All FAQs
What areas in San Diego County do you service?

We service every city in San Diego County, from coastal communities like Encinitas, Carlsbad, and La Jolla, to inland cities like San Marcos, Escondido, and Poway, through East County (El Cajon, La Mesa, Santee), South Bay (Chula Vista, National City), and the mountain communities. If you're in the county, we cover you.

How fast can you come out for a free water test?

Usually within 1–3 business days. A technician comes to your home, tests your actual tap water on the spot, and walks you through exactly what's in it. No pressure, no obligation. You see the results before we ever talk about a system.

How much does a whole-house water filtration system cost?

It depends on your water and the system that fits your home. Entry-level conditioners start around $1,500 installed. Full whole-house filtration with salt-free conditioning runs $2,500–$5,000 for most homes. Reverse osmosis drinking water systems are typically $400–$900. We give you a written quote after the water test, no guessing.

What is salt-free water conditioning and how is it different from a softener?

A traditional softener swaps calcium and magnesium ions for sodium, which means bags of salt to haul, a brine discharge, and sodium added to your water. Our PF1025 catalytic media conditions the water without salt or sodium. Scale-causing minerals are neutralized so they don't stick to pipes and fixtures, but they're not replaced with sodium. Nothing to haul. No brine. Better for the environment and your drinking water.

Why does it matter what the tank is made of?

Most competitors use fiberglass tanks lined with plastic. Over time those liners can degrade and shed into your water. Our tanks are medical-grade 304 and 316 stainless steel, the same alloy used in surgical equipment. They don't corrode, they don't degrade, and they don't introduce anything into your water supply.
