Dear CTU Students and Staff,

A LOKNI water dispenser is planned to be installed at the Podolí Dormitory Complex (next to the administration building). It will allow you to fill up with free filtered still or sparkling water via the LOKNI mobile app, with a daily limit of up to 3 litres (still/sparkling). The installation is scheduled to take place between July and August 2026.

To use the dispenser, you will need to download the LOKNI app to your mobile device.

How to get started

1. Download the LOKNI app from Google Play or the App Store.
2. Register and select the FREE plan.
3. Hold your phone up to the QR code reader and start filling your bottle.

Why use LOKNI?

• Healthy hydration – water free from chlorine and chlorination by-products, unpleasant odours and tastes, microplastics, pesticides, pharmaceutical residues, hormones, and unwanted bacteria.
• Verified filtration – tested by the Faculty of Pharmacy, Charles University in Hradec Králové, and validated by the National Institute of Public Health.
• Environmentally friendly – reduce unnecessary plastic bottle waste.
