What does whole-house water filtration do that a pitcher filter does not?
A whole-house water filtration system treats the home’s incoming supply. A pitcher filters only water poured through its cartridge. Whole-house equipment can serve several indoor fixtures, depending on the plumbing layout. It doesn’t mean every system targets every substance. The licensed pro should test your water and explain the proposed equipment’s purpose.

What kind of water filters do San Diego homes need?
It depends on what the test finds, but San Diego water is hard and disinfected with chloramine rather than plain chlorine, and standard carbon filters do not break chloramine down. That is why a whole house water filter here is usually built around catalytic carbon, often paired with softening or salt-free conditioning for the hardness. A reverse osmosis unit at the kitchen tap covers drinking water separately.
Is reverse osmosis worth it in San Diego?
Reverse osmosis can be worthwhile in San Diego when your test results and drinking-water goals support it. It usually serves a specific tap instead of replacing whole-house treatment. Because source mix and hardness vary by service area and season, a countywide answer would be misleading. Start with the free in-home water test, then ask the licensed pro what the proposed system addresses.
