Overview

Practical Water Filtration for Your Home

Make everyday household water filtration simple with the INV-WF03-V2. This three-stage system combines 20″ PP, UDF and CTO cartridges to help reduce sediment, chlorine and unpleasant odours in municipal tap water. Blue coated housings and an iron mounting bracket bring the three stages together in one installation, with no electricity required.

Three Stages Working Together

  1. 20″ PP Sediment Filter – Captures sand, rust and suspended particles at the first stage.
  2. 20″ UDF Granular Activated Carbon – Helps reduce chlorine and unpleasant odours.
  3. 20″ CTO Carbon Block – Adds a further stage of carbon filtration for additional chlorine and odour reduction.

Designed for Everyday Use

  • No electrical connection needed: Operates using incoming water pressure.
  • Replaceable cartridges: Service the individual filters as needed to maintain filtration performance.
  • Three housings, one bracket: An iron mounting bracket holds the filtration stages together.
  • For municipal tap water: A practical filtration option for general household use.
  • 1/2″ (DN15) connection: For installation with compatible plumbing fittings.

Installation Requirements

Ensure the inlet pressure is within 1–4 bar. Confirm thread compatibility and mounting arrangement before installation. Allow access beneath the housings for cartridge changes.

Keep Your Filters Performing Well

Regular cartridge replacement helps maintain filtration performance. Use the following schedule as a guide:

Filter Recommended Replacement Interval
20″ PP Sediment Filter 3–6 months
20″ UDF Granular Activated Carbon 6 months
20″ CTO Carbon Block 6 months

Replacement intervals vary depending on incoming water quality and daily usage. Follow the supplied instructions for flushing and maintenance.

Warranty

Includes a 1-year warranty against manufacturing defects, including leakage caused by a manufacturing defect.

Water use: Designed for general household filtration. The filtered water is not intended for direct drinking; appropriate additional treatment and verification are required for drinking-water use.
