This manual provides expert answers to common consumer questions regarding air purifiers. It covers the types of indoor air pollutants (particulates, chemical gases, and microorganisms) and their sources, such as human behavior, furniture, and cooking fumes.
The document details the classification of air purifiers based on function and installation, explains various purification technologies like HEPA and activated carbon, and outlines core performance indicators such as CADR and CCM. It also offers practical advice on how to select a suitable unit based on room size and pollutant types, as well as guidelines for maintenance and filter replacement. This manual is written in Chinese.
Indoor air pollutants are mainly divided into three categories: particulates (such as PM2.5 and pollen), chemical gases (such as formaldehyde and benzene), and microorganisms (such as bacteria and mold).
Sources include human behavior (smoking, breathing), indoor decoration and furniture, home appliances, kitchen fumes, and atmospheric environment penetration.
Core indicators include Clean Air Delivery Rate (CADR), purification energy efficiency, noise, applicable area, cumulative purification quantity (CCM), purification life, standby power, and harmful substance emission.
You can estimate the applicable area by multiplying the CADR value by a coefficient ranging from 0.07 to 0.12.
