Overview
What is it?
The UPF‑S20 is a premium 20‑inch whole‑house pre‑filtration system engineered to capture silt, sand, rust, and large particulates at the source, protecting downstream softeners and appliances
Who is it for?
Designed for homeowners seeking source‑level particulate control, extended protection for all downstream appliances, and improved water quality for bathing, laundry, and everyday use.”
Why it matters?
Because upstream particulate removal prevents wear, reduces maintenance, and delivers cleaner, healthier water to every tap.
How it works?
Water passes through a 20‑inch, three‑layer stainless steel mesh with 40‑micron precision, physically intercepting silt, sand, and larger particulates to prevent them from entering your system.
