Regarding the innovation map for an air purifier, do the following:

(a) The company decides to develop a long-term strategy for the development of air purifiers. HEPA filters are used to remove solid particulates; plasma (http://www.plasma-air.com/how-it-works), UV (http://en.wikipedia.org/wiki/Ultraviolet_germicidal_irradiation), and ozone (http://www.understandingozone.com/about.asp) are used to kill bacteria and viruses; PCO is used to decompose VOCs. Develop an innovation map for using these materials for a product line of air purifiers.

(b) Make a survey of existing air purifiers on the market, and compare with the products identified in part (a).
