Coway Airmega 100 — features, strengths and limitations
Simple automatic cleaning for smaller rooms
Editorial review Reviewed 28 October 2026 How we assess products
The Coway Airmega 100 provides useful automatic particle cleaning without an app, Wi-Fi or an account. Touch controls and a colour ring keep it simple, while quiet low settings and switchable lights suit bedrooms. Its 244m³/h declared airflow is useful in a small room; the 51m² coverage claim assumes only two air changes an hour. The compact body fits a home office easily, but its carbon stage is limited against strong cooking odours. There is no remote scheduling, voice control or detailed history. Use the exact Airmega 100 replacement filter when due; the similarly named Airmega 50 uses a different filter. It is a sensible budget choice when straightforward cleaning matters more than connected features.
