i started a separate thread discussing the best air purifiers but didn’t come across anyone who has personally used the Coway Airmega AP-1512HH. Some users have praised Blueair for long term reliability but due to budget constraints and Coway’s sleek design, i am leaning toward purchasing the Coway Airmega.

If anyone has experience using the Coway Airmega AP-1512HH, i would love to hear your thoughts. Would it be a good fit for a 400-square-foot room? Any insights on its performance for long-term use would be greatly appreciated.
