Roccheggiani's DIF Diffuser provides arguably the finest diffusing technology to any environment it is installed into. Perfect for offices, big spacious rooms such as showrooms, meeting rooms, conference rooms, home rooms, and many of the same kind, this diffuser need only be installed on the wall--or better yet, up on the ceiling--and it will purify away. Its designers and manufacturers over at Rocchegianni made it so as to feature natural anodized aluminum elements, which fix air flow to the desired preference. These elements also enable multiple preset air flow angles to exist, and in turn, create multi-directional air flow capabilities.
