About us
For over 30 years

Since 1984, Purified Air Ltd. has been a market leader in indoor air quality filtration and odour control for commercial kitchens.

With the majority of household named restaurant and catering brands already using our systems, Purified Air covers the Fast Food, Casual Dining and Fine Dining markets by providing bespoke systems dependant on the type of food cooked, the type of cooking process used and the volume of air being extracted through the exhaust. By working with these variables we are able to design and supply some of the best commercial kitchen exhaust filtration and odour control systems in the world.

Our adaptable range of indoor air quality products incorporating UVGI technology offers up to 99.99% efficiency and up to 99.9% kill rate for many viruses and bacteria.



In 2004 Netcen was asked to produce a report on behalf of the Department for Environment, Food and Rural Affairs on Guidance on the Control of Odour and Noise from Commercial Kitchen Exhaust Systems and in January 2005 the DEFRA Guide was published.

Leading from the Front

Our Managing Director, David Collins, was consulted extensively during the preparation of the DEFRA guide and was very pleased to be able to assist NETCEN and DEFRA. David has been working in this business since the early 1980’s and is a world renowned expert in the field of commercial kitchen exhaust filtration.

Keeping the kitchens open

Councils up and down the country have powers under the Environmental Protection Act 1990 to ensure that commercial kitchens comply with the DEFRA Guide and that is where Purified Air comes in, ensuring that the extract from commercial kitchens, when finally exhausted, is as clean and odourless as it possibly can be, keeping the kitchens open and their neighbours happy.
