Coway Airmega AP-1512HH Mighty vs Coway Airmega 400(G) Air Purifier
Buy the Mighty AP-1512HH for a bedroom, office, or single room up to about 360 sq ft. Buy the Airmega 400 for an open-plan living area, a whole floor, or a home with pets and cooking odors. The Mighty is smaller, lighter, and simpler, with a washable pre-filter and a proven long-running design that owners rate highly. The 400 is a much bigger dual-sided unit with far higher airflow and smart auto control, but it is large, heavy, and needs two Max2 filters replaced.
- Choose the Coway Mighty AP-1512HH if you need quiet, reliable HEPA cleaning for one room and want a compact unit with a washable pre-filter.
- Choose the Coway Airmega 400 if you are cleaning a large open space and want dual-sided filtration, high airflow, and automatic smart operation.
