Smoke removal is positive where discussed, including a large-space recommendation for smoke and a garage/workshop user reporting excellent results around smoke-producing work.

Pros: air purification performance, particle removal effectiveness

Cons: voice assistant compatibility, filter replacement cost

#2 Coway Airmega 250

Smoke removal evidence was strongest in the long-term fire and wildfire account, where indoor air remained comfortable despite severe smoke outside.

Pros: smoke removal, CADR rating

Cons: filter replacement cost, app connectivity

#3 Coway Airmega 350
4.5

Smoke removal scored well overall, especially in incense, cigarette smoke, and Intense Smoke+ filter discussions.

#4 Coway Airmega Mighty AP-1512HH
4.5

Smoke performance is generally strong in tests, with praise for heavy-pollution handling, smoke-box results, and match/incense particle removal.

Pros: durability, pollen removal

Cons: child lock, VOC reduction

#5 Coway Airmega Mighty2
4.5

Smoke removal was strong in WIRED's smoke test and CNET's apartment smoke context, with fast clearing and adequate filtration reported.

Pros: filter life, power consumption

Cons: voice assistant compatibility, app connectivity

#6 Coway Airmega 250S
4.5

Smoke removal evidence was positive but limited, mainly from PCMag's broad removal claim and incense-based testing context.

Pros: pre-filter quality, room coverage

Cons: fan speed options, filter replacement cost

#7 Coway Airmega 200M
4.3

Smoke performance is mostly positive, with clear rooms and wildfire/cooking smoke improvement, though smell control is a separate mixed point.

Pros: durability, ozone-free operation

Cons: app connectivity, smart features

#8 Coway Airmega 100
3.7

Smoke removal was mixed-positive: it handled light smoke or smoke particles, but one review framed carbon performance as only okay.

Pros: ozone-free operation, true HEPA filter

Cons: handle design, pre-filter quality

#9 Coway Airmega 50
2.9

Smoke handling is mixed. It can clear light or controlled smoke in compact spaces, but brief smoke bursts, heavy cooking smoke, and cigarette odor can exceed what this tiny unit...

Pros: ozone-free operation, breathing relief

Cons: reliability, customer support

#10 Coway Airmega 150
2.5

Smoke removal was limited by the low Smoke CADR, making it better suited to personal or small-room use.

Pros: maintenance ease, ozone-free operation

Cons: voice assistant compatibility, child lock
