Based on my experience, this air conditioner is a wonderful addition to my home! The air quality is noticeably improved, thanks to the built-in humidifier. The unit is also surprisingly quiet, making it perfect for use in a bedroom or home office. The one drawback is that the heating function can be a bit slow, but it's not a major issue. Overall, I highly recommend this air conditioner for anyone looking to upgrade their air quality and stay cool in the summer months.
