Coway filters are integral to maintaining clean, healthy air. Their multi – stage filtration system, like the Max2Green filter set, combines a pre – filter, Green True HEPA™ filter, and activated carbon. The pre – filter traps large particles such as dust and pet hair, extending the main filter’s lifespan. The Green True HEPA™ filter captures 99.9% of viruses, bacteria, fungi, and pollen, while the activated carbon filter removes 99% of odorous gases and VOCs. These filters are designed specifically for Coway air purifiers, ensuring optimal performance. Regular replacement, as indicated in the product manual, guarantees continuous efficient air purification for a fresher living environment.
