The web site aims to provide information about the company's range of products and services in a clear format that users should find easy to use.
Interactive tools include a spare-parts request service, online guarantee-card registration, an online inquiry service and a monthly reminder to users to replace their water filter cartridge.
Charlotte Ward, marketing manager for Brita, said: "The site has worked well for three years. In line with our new marketing push, we felt the time was right to update the design of the web site."
She continued: "Improved fun-ctionality will help us to provide a better service to consumers and give us more options in the future for additional activity and services."
Incumbent internet design firm Wax New Media, which ran Brita's previous site for three years, created the new one.
