Meer over het boek

Focusing on portable air purifiers in China, the book explores their development, types, and application principles. It critiques the "Clean Air Delivery Rate" for inadequately reflecting operational challenges and contrasts theoretical characteristics with measured data. Key design features and calculation methods for indoor particle concentration and self-purification time are discussed. Additionally, it addresses window opening conditions during smog and offers guidance for selecting air purifiers, concluding with a novel assessment index to enhance measurement accuracy.
