The fan used in both the Sqair and Qilive air purifiers are the same. When using the air purifiers with only a HEPA filter, the performance of both machines is the same. They both have a particulate CADR of 315cbm/hr.
The carbon filter used in both machines, however, is different. The Sqair’s carbon filter offers slightly higher airflow and subsequently higher performance when compared to the Qilive filter, due to the use of an improved carbon structure.
If your main concern is particulate air pollution (for example PM2.5, dust and viruses), then you may use the Sqair or Qilive air purifiers with HEPAs only interchangeably.
