Whole House Filter

Lan Shan’s Whole House Filter series is a point-of-entry (POE) filtration system – installed where water first enters a building to treat all downstream taps and appliances. Designed to remove sediment, chlorine, and odors, it helps protect plumbing and improve overall water quality. These filters are often used as pre-treatment for a reverse osmosis system, helping reduce the load on RO membranes and extend their lifespan.

The series includes models for residential and light commercial use, with 10” and 20” filter housings to support different flow rates and installation requirements. Choose from 1-stage systems with a sediment filter to capture rust, sand, and dirt, or 2- and 3-stage models that add carbon filtration to reduce chlorine, odors, and chemical residues.

Installation options include coated metal or stainless steel brackets, floor stands, and protective covers. All models support optional pressure release buttons for easier handling and pressure gauges to assist with maintenance monitoring.

Whether for a household or a small business, our Whole House Filter series offers a flexible, high-capacity solution for reliable whole-system water protection.
