Coway Airmega Mighty vs Winix 5500-2
Close on performance. The Coway scores higher for having no ionizer at all; the Winix is competitive if you turn PlasmaWave off and value its washable carbon filter.
Both are AHAM-verified medium-room units with similar CADR. The Coway has no ionizer; the Winix adds a defeatable PlasmaWave ionizer and a washable carbon pre-filter that can lower running cost.

FAQ
- Is the Winix PlasmaWave safe?
- It is a defeatable ionizer. We credit a defeatable ionizer only when CARB ozone compliance is verified; otherwise we leave the points off. You can run the Winix with PlasmaWave switched off as a plain HEPA filter.
