• Ionizer: Some Coway models include an optional ionizer which releases negative ions to attract and neutralize airborne particles. This feature enhances air quality by causing pollutants to clump together, making them easier to trap.

Each filter plays an integral role in enhancing indoor air quality, ensuring that Coway air purifiers remain effective and efficient in various settings. Regular maintenance and timely replacement of these filters are vital for optimal performance.
