Recommended room size is based on CADR, assuming the air is already well-mixed. But in real life, pollution is uneven, so we use even purification coverage to show how far our airflow reaches. With Dreame's 10-meter wind projection, we cover up to 157m, meaning air gets cleaned everywhere, not just nearby.
What's the difference between recommended room size and even purification coverage for Dreame Air Purifier?
