Jafanda Air JF280 CADR and room size
Recommended room size is about 209 sq ft (CADR × 1.55). That is approximately 4.8 air changes per hour in a room with an eight-foot ceiling. The manufacturer figure of 1015 sq ft corresponds to about 1.0 air change per hour at the same ceiling height and is shown separately. Our recommended room size uses approximately 4.8 air changes per hour with an eight-foot ceiling. Manufacturer coverage figures may use a lower air-change rate and are shown separately.
The manufacturer coverage claim is higher than 3× CADR, so it is not used for ranking.
