1. Air Cleanliness Level According to the “Air Clean Technical Measures” prepared by the National Construction Committee, air cleanliness in air purification is divided into five levels according to the number of dust particles contained in each litre of air. Level 3: Air per litre The average number of dust particles with ≥ 0.5 micron does not exceed 3 particles; Level 30: The number of dust particles with ≥ 0.5 micron per litre of air
