Note to readers: This post was updated on July 22, 2026 to give a more accurate, balanced look at whole-house water filtration options and add links to our related water quality guides. We refreshed the details below so the advice reflects how we approach this work today.
If your Duarte home was built before 1970, there’s a good chance older galvanized or copper plumbing is still in place, and city water treatment chemicals like chlorine can leave a noticeable smell or taste at the tap. A whole-house water filtration system is one of the most effective ways to address that at the source, rather than filtering water one glass at a time.
Why Older Duarte Homes Notice It More
Duarte’s history as a citrus-growing community goes back to the 1880s, and many neighborhoods still have homes from that earlier building era. Older plumbing systems are more prone to mineral buildup and can be more sensitive to the chlorine and chloramine levels used in municipal water treatment. If your water smells like a swimming pool, tastes slightly metallic, or leaves residue on fixtures, that’s usually what’s happening.
Signs Your Water Quality Needs a Closer Look
- A noticeable chlorine or bleach-like smell from tap water
- Skin feeling dry or irritated after showering
- Hair feeling different or harder to manage after washing
- Spots or scale buildup on faucets, showerheads, or glassware
- A metallic or off taste in drinking water
Any of these are worth getting checked with a simple water quality test rather than guessing.
What a Whole-House Filtration System Does
Whole-house water filtration systems, including Halo 5 systems, are installed at the point where water enters your home, so every tap and fixture gets filtered water — not just the kitchen sink. These systems are designed to reduce chlorine, sediment, and certain heavy metals depending on the filtration media used.
If your home also deals with hard water (common throughout the San Gabriel Valley), it’s worth discussing a water softener alongside filtration — they solve different problems and are often paired together.
Benefits Worth Considering
- Better tasting, better smelling water at every tap in the house, not just one filtered pitcher.
- Less irritation for households where chlorine sensitivity affects skin or hair.
- Protection for your plumbing — reducing scale and mineral buildup helps fixtures and pipes last longer.
- One-time installation instead of ongoing bottled water costs or replacing pitcher filters constantly.
Costs vary depending on your home’s plumbing setup and the system chosen — see our breakdown of whole-house filtration system costs for a general idea before you commit to anything.
