Abstract：Indoor formaldehyde pollution poses a serious threat to health,urgently requiring efficient control.Air conditioning systems integrated with formaldehyde removal functions,leveraging their advantages of wide coverage and high frequency of use,serve as an ideal platform for the synergistic regulation of temperature,humidity,and air purification.This paper systematically reviews the sources and long-term release characteristics of indoor formaldehyde.The principles,effectiveness,and limitations of mainstream formaldehyde removal technologies integrated into air conditioners were critically examined.Moreover,the constraints on actual performance imposed by dynamic environmental parameters,complex pollution sources,system compatibility,and user requirements were analyzed.Finally,the key direction of aldehyde removal technology upgrading is prospected,which provides guidance for the research and development of the next generation of efficient and intelligent purification solutions.
