Coway Airmega 250

What the current documentation establishes

Coway publishes CADR of 249 CFM smoke, 261 CFM dust and 230 CFM pollen and gives room-size examples at multiple air-change rates: 1,860 sq ft at 1 ACH, 930 sq ft at 2 ACH and 465 sq ft at 4 ACH. The filter stack is a washable pre-filter plus Coway’s Max2 activated-carbon/HEPA filter.

The manufacturer lists 64 W maximum power, 22–54 dBA sound, 20.5 lb weight and dimensions of 18.5 × 19.7 × 8.3 inches.

Why this is useful beside Vollara

Coway’s room-size claims expose the air-change basis, while Vollara’s manuals use fan airflow and manufacturer coverage/diffusion statements. Putting those numbers into one undifferentiated square-foot column would be misleading.

Ozone and ionization disclosure

The cited Airmega 250 page lists a three-stage mechanical/carbon/HEPA filtration system and does not list an ionizer stage or publish a numeric ozone-output specification. That is a documentation statement, not an independent zero-ozone measurement.

Warranty

Coway’s current U.S. warranty policy lists one year for internal/functional parts and, for Airmega models outside its specifically excluded product groups, three years for motor/electronic parts. Eligibility depends on purchase source, registration/proof-of-purchase requirements and the current warranty terms.

Evidence boundary

Homeapotherapy has not independently reproduced CADR, acoustics, power use or emissions measurements. Values shown here are manufacturer-published specifications.
