The best air purifier when dust keeps coming back
Our pick
Coway Airmega 400
The Coway Airmega 400 is the strongest all-round dust choice here because its 328-CFM certified dust airflow, two wide washable prefilters and automatic operation suit a busy living space. Pick the Core 600S-P for a smaller base and higher 398-CFM dust rating. Vacuuming still matters because a purifier only catches dust while it is airborne.

What matters in practice
How to choose for this need
Size for airborne dust, then choose the prefilter you will actually maintain.
More dust CADR shortens the airborne window
Core 600S-P has the highest exact dust CADR of the two leaders. Airmega 400 trades some airflow for two broad washable intake screens.
Settled dust needs cleaning
A purifier cannot lift dust from shelves or carpet. Use a sealed vacuum and damp wiping alongside continuous filtration.
What this comparison cannot tell you
- Dust sources differ by home
- Published CADR is measured with a clean filter at rated speed
