Peer Reviewed & Fact Checked

1. Filter Status Check

A QR on the under-sink unit or jug links to the filter status page: litres filtered, estimated days remaining, and water quality summary. Users check without a separate app or remembering installation dates.

2. Replacement Ordering

A QR links to the exact replacement filter for that model. Users add to cart and order in seconds without searching by model number. Pre-fill a subscription option to automate future replacements.

3. Installation and Setup Guide

A QR on the box or on the unit body links to the setup guide specific to the model: video installation walkthrough, connection diagrams, and initial flush procedure.

4. Water Quality Report

Where the system connects to a water quality sensor, a QR links to the real-time water quality dashboard: TDS, pH, and contaminant levels. Gives users confidence in the system's performance.

Frequently Asked Questions

Should a water filter QR require registration to show filter status?

Yes if the status is connected to a specific unit. Guest users see general product information; registered users see their unit's actual status.

Can a QR on a water filter prompt users to reorder at the right time?

Yes. The filter status page can show a "time to reorder" prompt when capacity drops below 20%.
