| Planning smoke CADR | 233 (Smoke) CADR | 231 CFM CADR; Levoit doesn't say smoke |
| Planning power | 77 W power consumption | 38 W rated power |
| Planning filter cost | $59.79 on Coway's Mighty filter set page (Oct 18, 2026) | $49.99 on Levoit's filter page (Oct 17, 2026) |

| Main strength | Listed smoke CADR and simple on-device controls | App control and about half Coway's power draw |
| Main risk | Higher listed power draw than Core 400S | Sizing still depends on room and target air changes, not app features alone |

Short answer
Coway lists 233 (Smoke) CADR and Levoit lists a 231 CFM CADR. Confirm certified ratings, filter price, noise, and controls on each product page before you buy.
Room-size marketing is not directly comparable. Use smoke CADR, ceiling height, target air changes, replacement-filter cost, and noise at the speed you will actually run.
