The Coway Airmega 100 is described as optimized to clean up to 405 sq. ft. in 30 minutes or 810 sq. ft. in 60 minutes. Both purifiers support medium to moderately large rooms, but the Clorox unit is specified for slightly larger spaces.

Final Summary
The Clorox Medium Room Air Purifier offers wide coverage, strong virus and bacteria filtration, and helpful real-time air quality feedback. Reviewers consistently praised its quiet operation and noted how well the auto mode performed.
