The filters used in the Qilive Q.6815 and The Sqair are not the same. That means the PM2.5 (smoke) CADR performance is different between these two products. You can check the Auchan website to find the CADR specific to the Auchan purifier.
The good news is, only the carbon filter is different between the two air purifiers. If you are more concerned with PM2.5 levels, and not toxic gases like VOCs and formaldehyde, you can remove the carbon filter from your purifier. This way, the Q.6815 or Sqair both achieve the same PM2.5 CADR of 315cbm/hr.
