Indoor Air Quality

There are a lot of products that claim to really clean your indoor air, but how do you know which ones really work?
Comparing the clean air delivery rate is a great place to start. The clean air delivery rate is the amount of clean air a system will deliver into your home for a typical 3-ton system as compared to other whole-house and appliance air cleaners. Two factors affect this rating-the efficiency of the filter material and the amount of air that passes through the device. This standard has been recognized by the Federal Trade Commission (FTC), Environmental Protection Agency (EPA), and American National Standards Institute (ANSI) as a fair and objective comparison of various air cleaning technologies.

Below is a comparison chart from Consumers Reports in summer of 2005. Note: At the time of this report the Trane Clean Effects was not available yet. Based on studies from other groups, since it's introduction to the market we are sure it would have made the top of this list.
