Great sunshine. Air and water worth a second look. That's California.
Some of the worst smog in the nation, wildfire smoke every year, and hard water piped in from the Colorado River. Here is why California households put air and water purifiers high on the list, based on public data.

ALA "State of the Air" 2026, based on 2022–2024 monitoring data
During the January 2025 Palisades and Eaton fires, indoor PM2.5 rose in homes across every LA neighborhood studied.

California is the only state with its own drinking water standard for chromium-6. Large water systems must comply starting fall 2026. Before the standard, 129 water systems serving about 4.1 million people had reported levels above this number.
Where you live changes what matters
Priorities shift from region to region, even within California.
Los Angeles & Orange CountyKoreatown, Irvine, Fullerton
Among the worst ozone in the nation. During the January 2025 fires, indoor particle levels rose even with windows closed. Most tap water here is hard.
Inland EmpireRiverside, San Bernardino
San Bernardino and Riverside rank #1 and #2 among U.S. counties for smog, each with more than 100 unhealthy ozone days a year.
San DiegoCarlsbad, Chula Vista
Tied #5 nationally for year-round particle pollution. Heavy reliance on imported water keeps hardness around 13.5 gpg on average.
Central ValleyBakersfield, Fresno, Visalia
A basin ringed by mountains traps pollution. The nation's #1, #4 and #5 metros for year-round particles are all here.
Bay AreaSan Francisco, San Jose, Oakland
Usually cleaner air, but still #13 nationally for year-round particles, and Northern California fire season can blanket the whole bay in smoke.
A year in California air
Air quality concerns don't stop after one season.

Typical patterns only; timing varies by year and region. As the January 2025 LA fires showed, major fires can happen in winter too.
The honest version
Most California tap water meets state and federal drinking water standards. A water purifier doesn't make unsafe water safe; it's an extra step for taste, odor, scale and specific contaminants.
Hard water is not classified as a health risk. The trouble is mostly scale, taste and wear on appliances.
Each model reduces different contaminants. Before you buy, we'll check the model's NSF certifications against your water utility's annual Consumer Confidence Report with you.
Find the right purifier for your neighborhood's air and water.
