22 facts in comparison
This comparison puts the Winix 5500-2 and Coway Airmega 200M side by side — two Air Purifiers measured against the same 22-spec sheet, with every meaningful gap scored and explained. On our weighted VS Score the Coway Airmega 200M finishes ahead, 97 to 61 — a decisive result.
The most consequential difference is sleep mode — the Winix 5500-2 has it, the Coway Airmega 200M does not. None of our retail partners currently lists the Winix 5500-2, so availability may be limited and price cannot factor into this comparison.
The spec sheet pulls in both directions. These are the gaps big enough to shape the decision — with the actual figures, and what each one means in real-world use.
A dimmed, near-silent mode for overnight use.
The lowest-speed noise output; quieter suits bedrooms.
On paper this is a win, but a gap this small is unlikely to be noticeable in daily use.
Clean Air Delivery Rate — how quickly smoke particles are scrubbed from the air.
On paper this is a win, but a gap this small is unlikely to be noticeable in daily use.
A lighter unit is easier to move between rooms.

There is no single answer — it depends on what you will actually use it for. Match your priority to the pick below.
Drag the sliders to weight each category and re-rank the products to suit your priorities.
Every measurable spec is scored relative to this matchup: the best value here earns 100%, the worst 0%, and everything between scales linearly. Each spec then counts according to an editorial weight that reflects real-world impact — a battery-capacity gap moves the score far more than a colour-options list. The category scores above are the weighted results inside each group, and the overall VS Score rolls all of them together; the evidence line under each category names the specs that actually decided it.
Unknown values are never estimated. A spec a product doesn’t report simply drops out of that product’s scoring — it isn’t penalised with a guess — and a spec only one side reports can never produce a “win”. The trade-off is honest but real: a thinner spec sheet means a score built on fewer data points, which is why the completeness figures are disclosed under About this data.
Most importantly: a spec-sheet lead is not the same as a better product. Megapixels, gigahertz and benchmark points describe capacity, not experience — image processing, software optimisation, thermals, haptics and ergonomics decide how a device actually feels, and no table captures reliability or long-term support quality. Treat the scores as a structured summary of what can be measured, read the caveats under each key difference, and use the weight tuner to re-rank the comparison by what matters to you.
