The company

The Biotech Group was created by Roberto Saija, Gregory Martinez de Riquelme and Steve Skerrett.  With backgrounds as entrepreneurs in engineering, real estate, architecture and finance, they have recognised the importance and relevance of the Cleanair product and see the significant benefits it can bring to indoor spaces in the UK, not only today but in the longer term to improve well-being in the workplace, educational, healthcare and retail environments.

We are a UK based company focused on creating healthy living environments.  Our clients want to improve all aspects of indoor air quality.

We have partnered with CleanAir Spaces to bring their patented technology to the UK.  This technology is proven and tested and removes viruses in air and on surfaces.  In a recent study carried out by the University Hospital in Granada (part of the Spanish Health Service) it was concluded that this technology can eliminate 100% of the coronavirus, 99.75% of the flu virus (H1N1) and 99.99% of the enterovirus.

The technology provides continuous disinfection of air and surfaces 24/7.

The business started in China where 1.25 million people die early each year as a result of air pollution and where 81% of the population breathe air which has yet to reach the first interim air quality target set by the WHO.  However, with the emergence of Covid-19 the business has concentrated its efforts on the role this technology can play in combatting the virus.

Clients across the world and from all types of industries have installed our devices, including Aldi, Ikea, Inditex, Grand Hyatt, Microsoft and Loewe.

In excess of 300 clients have already installed our technology into 28 million square meters of work and retail spaces with over 600,000 employees worldwide now protected by our systems.
