         Manufacturer of purification boxes, HEPA purification box wholesale, activated carbon purifier. The split-type HEPA purification box is installed at the air intake and is compatible with the total heat recovery fresh air system and dual-flow fresh air fan, effectively filtering harmful substances from outdoor air. It features a four-stage progressive purification process: pre-filter, silver ion filter, activated carbon filter, and HEPA filter. This multi-layer protection ensures that indoor air remains healthy and fresh.         Features of Split-Type HEPA Purification Box:   Pre-Filter: With a large filtration area, it effectively prevents large particles of dust (such as dirt, debris, pollen, and hair) from entering the unit. Silver Ion Filter: Utilizes the sterilizing power of silver ions to eliminate various bacteria and control bacterial growth. Activated Carbon Filter: Made from specially processed granular activated carbon, this filter has a porous structure that purifies all types of air pollutants. It has strong adsorption capabilities, capturing fine particles, bacteria, and effectively adsorbing formaldehyde, ammonia, hydrogen sulfide, and other harmful substances. HEPA Filter: Effectively filters dust, smoke, and bacteria, as well as PM2.5 from haze. The lifespan of the filter is primarily related to the level of outdoor air pollution. When outdoor air pollution is severe, the filter should be cleaned accordingly and in advance. Generally, it is recommended to replace the HEPA filter every three months to prevent saturation from prolonged use, which can lead to a decline in purification efficiency.        However, it is important to note that the HEPA filter cannot be washed with water! Maintenance involves direct replacement, and it cannot be reused like the activated carbon filter or pre-filter. The Zhongdian New Air split-type HEPA purification box offers a total of 4 models with varying airflow options, ensuring that there is always a suitable choice for your fresh air system.
