Don't believe me? There's a mass of data available at the Plants for People website to back me up.
As for what plants work best, you need a lot of leaf area, so broad-leaved plants are best, and high humidity is encouraged by thirsty plants. So a broad-leaved Ficus, like the burgundy rubber plant I installed in Southampton last year is ideal.

Air-improving alternatives to the Ficus family include broad-leaved Dracaenas, Spathiphyllums and Aglaonemas. You'll find pictures of all of these on the main office plants website.
