Purification principle of Hall fresh air system

The Hall fresh air system is designed to create a high-quality home environment for family members. It filters and purifies fresh air with sufficient oxygen content from outside through multiple processes before sending it indoors. At the same time, it discharges polluted indoor air to the outside and ensures that the indoor air is always in a clean and fresh state through 24-hour continuous circulation and replacement.

Hall Fresh Air adopts the world's top NEPT air purification technology, breaking through the traditional filtering purification characteristics, and efficiently filtering the gas entering the room through four layers. It not only efficiently kills harmful microorganisms, bacteria, and viruses in the classroom air, but also discharges harmful gases such as formaldehyde, benzene, and carbon dioxide, eliminating odors in the air. At the same time, it has a super strong purification effect on fine and small pollutants such as PM2.5 and bacteria. The purification rate for biological, chemical, physical, and odor pollution sources is all above 99%.
