Clean water for all

For nearly fifty years we have been providing water purification tablets and baby bottle sterilising tablets to 60 plus countries.

Our History

Cert. is brought to you by Hydrachem.

Born and raised in a small rural Sussex village in England almost 50 years ago, Hydrachem is now one of the world’s leading manufacturers of premium water purification, baby bottle sterilisation & hospital disinfection tablets.

UNICEF, Oxfam, Medecin Sans Frontieres and the WHO are just some of the distinguished organisations who have turned to our products to turn around the daily lives of those denied the most basic of human needs - clean water.  

Our Global Impact

No-one should have to drink dirty water from old fizzy pop bottles, but so many are forced to do exactly that, in war ravaged disaster zones and impoverished regions of the world.

We make 10 billion litres of water safe to drink globally every year, by supplying water purification tablets to areas suffering dysentery, diarrhoea, cholera and water-borne diseases.

From the world to your work surface

Over 95% of the NHS’s hospital disinfection tablets are made by Hydrachem.

The 2020 pandemic brought with it a need for people to feel safe and protected in their homes from outside contamination, so we decided to make our disinfection tablets available for use at home.

Cert. was born, with the goal of delivering a safe and effective way for people to keep their homes germ-free, providing the same peace of mind you would expect in a hospital.

We wanted people to feel safe wherever they are, and we wanted Cert. to be something that could provide protection at home, in the office, or wherever people go about their daily lives.

Refill-Reuse Revolution

Water sanitisation has always been our priority, but water purification has a new global problem...plastic pollution.

How could we bring our cleaning tablets to homes across the UK, whilst also protecting our oceans in the ongoing war on single-use plastic?

We are proud to be part of the reuse & refill revolution. Every carton of Cert saves 32 bottles of single-use plastic from joining our already creaking ecosystem.

We are also opposed to holding perfectly good drinking water hostage in plastic bottles.

Cert. tablets are designed to keep water within the Earth's water cycle, rather than needlessly hoarding it in cargo ships, warehouses or supermarket shelves.
