Abstract: Air quality information-sampling system is an important part in the whole air cleaner system. This paper introduces an air quality information-sampling system which has been designed and made out. As the complexity and randomicity of the air, this paper raises another new system on the base of the former system. This new system includes the LMS adapter filter subsystem which can make good performers in stochastic environment. It makes the new system more steady, predictable and intelligent.

Key words: adapter filter, air information-sampling, air-cleaner, LMS
