FAQs
What is a point-of-use (POU) water filter and how does it differ from whole-house filtration?
A point-of-use filter is installed on the specific fixture where you draw water—such as a kitchen sink, refrigerator dispenser, or dedicated drinking tap—so the water is purified immediately before use. A whole-house (point-of-entry) system treats all the water entering your home, including showers and laundry. POU filters typically focus on improving taste, odor, and drinking safety, cost less to install, and let you tailor filtration technology (e.g., carbon block, reverse osmosis, UV) to the water you actually ingest.
Why might Kelso residents need a POU water filter even though municipal water is treated?
Kelso’s municipal supply meets state and federal safety standards, but many homeowners still choose POU filtration to: • Remove residual chlorine/chloramine that affects taste and smell. • Reduce trace contaminants like lead, PFAS, agricultural runoff, and micro-plastics that can reach taps through aging service lines or household plumbing. • Provide an added barrier for immune-compromised family members, infants, and pets. • Avoid buying single-use plastic bottles while still enjoying great-tasting water. POU systems give you control over the final quality right where it matters—your glass.
What contaminants can your Kelso-installed POU systems remove?
Our certified filters can tackle a wide spectrum of impurities: • Sediment, rust, and turbidity down to 0.5 micron • Chlorine/chloramine and associated disinfection by-products (THMs) • Heavy metals such as lead, mercury, and chromium • Volatile organic compounds (VOCs) and pesticides common to agricultural areas around Kelso • PFAS compounds (“forever chemicals”) • Cysts, bacteria, and viruses (with UV or RO stages) We analyze your tap water and recommend the most appropriate cartridge or multi-stage system for your needs.
How is a point-of-use filter installed and how long does it take?
Installation is quick and non-intrusive. A licensed Kelso plumber mounts the filter housing (or RO system) under your sink, connects it to the cold-water line, and adds a dedicated drinking faucet (or ties into your fridge dispenser). For most kitchens, the job takes 1–2 hours with no structural changes. We sanitize the lines, pressure-test the unit, and walk you through operation and maintenance before we leave.
What maintenance is required and how often do I change the cartridges?
Maintenance is straightforward: • Carbon or sediment cartridges: replace every 6–12 months, depending on water usage and quality. • RO membranes: every 2–3 years. • UV lamps: annually. A built-in flow meter or simple calendar reminder helps you stay on schedule. We offer an annual service plan that includes filter changes, system sanitization, and performance checks so you never have to track part numbers or disposal.
What are the costs and long-term savings of installing a POU filter in Kelso?
Typical turnkey installation (equipment + labor) ranges from $225 for a single-stage carbon unit to $750–$950 for a multi-stage reverse osmosis system with remineralization. Annual operating costs average $40–$120 for replacement cartridges. Compared to buying bottled water ($300–$600 per year for a family of four), a POU system pays for itself within the first 12–18 months while reducing plastic waste and providing a continuous, on-demand supply of purified water.
