First, the honest baseline
Vancouver-area city water is safe to drink. It's disinfected, monitored, and the utilities publish their test results every year. If anyone shows you a scary jar-and-tablet demo at your kitchen table, know that the demo is engineered to look alarming — most of those tests react to harmless minerals.
So why treat it at all? Because "meets standards" and "the best water your family could be drinking" are different bars — and because two things in modern city water are worth understanding: chlorine and PFAS.
Chlorine and its byproducts
Chlorine (or chloramine) is added on purpose — it's what keeps water safe between the treatment plant and your tap, and it's genuinely good engineering. The trade-offs: it's why tap water can taste and smell like a pool, it's drying to skin and hair, and as it works it forms disinfection byproducts (like trihalomethanes) that regulators limit and most people would rather minimize.
The fix is straightforward: whole-home catalytic carbon filtration removes chlorine and its byproducts after they've done their protective job — right where the water enters your house. You keep the safety, skip the pool taste.
PFAS, in plain English
PFAS are a family of synthetic chemicals used for decades in non-stick coatings, firefighting foam, and water-resistant everything. They're called "forever chemicals" because they don't break down — in the environment or in bodies. Health research links long-term exposure to a range of concerns, and regulations are tightening as the science firms up.
Locally: PFAS have been detected in some Clark County sources, and state-mandated testing is ongoing. That's not a panic headline — levels and locations vary — but it's a fair reason to want a last line of defense at the tap you drink from.
What RO removes (and what it doesn't)
Reverse osmosis forces water through a membrane with pores small enough to reject dissolved contaminants — PFAS, lead from old plumbing, nitrates, and most total dissolved solids — then polishes taste through final carbon stages. Our under-sink units run seven stages and feed a dedicated faucet.
- RO handles: PFAS, lead, nitrates, arsenic, dissolved solids, and the last traces of anything the carbon missed.
- RO doesn't do: your whole house. It's a drinking-and-cooking tap solution by design — treating shower water for PFAS isn't where the exposure is.
The bottled water math
A family drinking bottled water spends real money every month to solve exactly the problem an RO tap solves once — and ends up hauling plastic for the privilege. If bottled water is in your budget already, RO usually pays for itself; the fridge water stops being a compromise, and the plastic bin gets lighter.
