They value extensive smart features, including app/voice control and comprehensive real-time environmental sensors (PM2.5, temp, humidity). While its 73.8 CADR is modest for 4000 sq ft, they are comfortable with a slower, gentler purification process over a vast area, or intend to use it primarily for maintaining good air quality rather than rapid remediation.
