Analysis Summary

The Coway air purifier has received overwhelmingly positive reviews from customers, with a high rating of 4.6/5, indicating strong satisfaction with its performance. However, the brand's relatively low trust score of 30/100 raises some concerns about its overall reputation and long-term reliability.
