After conducting tests, we found that adding a pre-filter will reduce the CADR. Additionally, if the pre-filter is not replaced in time, it will cause the purifier to be louder and effectiveness to lower. Since the pre-filter will add trouble to the user, we decided not to add a pre-filter in the Sqair.
Why Is There No Pre-Filter in Front of the HEPA Filter for the Sqair?
