US consumer water purification and air cleaning system demand will increase 4.4 percent annually through 2012. Reverse osmosis and distillation types will be the fastest growing water purification systems. Electrostatic air cleaners will outpace conventional air filtration systems.

This study analyzes the $1.2 billion US purification and cleaning system industry. It presents historical demand data for the years 1997, 2002 and 2007, and forecasts for 2012 and 2017 by technology (e.g., conventional filtration, reverse osmosis, distillation, ultraviolet, ozone, electrostatic, ionization), product (e.g., point-of-entry water purification, point-of-use water purification, whole-house air cleaning, portable air cleaning) and regional market.

The study also considers market environment factors, details industry structure, evaluates company market share and profiles 35 industry players, including Brita, PUR Water Purification Products and General Electric.
