Coway Airmega Mighty AP-1512HH vs Coway Airmega 200M vs Coway Airmega Mighty2 AP-1512N
Power draw is the line that separates these three Coways, because on airflow they are close to the same purifier. The Airmega 200M is the AP-1512HH Mighty in a squarer case, and the specs bear that out: the same filter layout, the same height, the same sensor ring and Eco mode, a smoke CADR within a few cubic feet a minute and an identical room rating. The Mighty2 AP-1512N is the newer generation, with a little more airflow and a slightly larger room rating, a gap too small to choose on.
So the decision moves off the airflow figures. The Mighty2 runs on markedly less power than either older model, it is quieter at both ends of its fan range, and it adds a numeric particle readout beside the color ring. In exchange, its carbon and HEPA layers sit in one combined cartridge, so both are replaced together once a year. The older pair use a separate deodorization filter, changed more often, next to a yearly HEPA. That is two parts to remember, though each is cheap.
None of the three has Wi-Fi, an app or voice control. If you want scheduling, phone alerts or air-quality history, all three are wrong for you, and Coway keeps those for its connected models. Someone who wants an appliance with no account, and nothing that stops working when a service shuts down, is well served by any of them.
The 200M also lacks a listed sleep mode, which the Mighty has, so a light sleeper should keep it out of the bedroom. The AP-1512HH is the outgoing model and makes sense only when a discount closes the gap to its successor. For a purifier left running around the clock, the two older machines are the wrong buy for anyone who will be paying the electricity bill for years.
Editor’s note
Coway's newer Mighty2 wins this on a wattage figure. It is rated at 56 watts at full speed, against 77 for the AP-1512HH and 82 for the 200M, while its smoke CADR of 240 sits between the older pair's 233 and 246. Its quietest setting is rated at 19 dB, five below the other two. Its filter is one combined cartridge, so a home that uses up the carbon early replaces the HEPA with it.
The AP-1512HH earned its long run as a default recommendation. It publishes a smoke CADR labeled as such, it has a real dust sensor and an Eco mode that stops the fan in clean air, and it needs no account. Its weakness is power, which has aged badly next to its own successor.
The 200M is that machine in another shape, with a slightly higher draw and no listed sleep mode. I'd pay for it what I would pay for a discounted Mighty, and no more. Anyone who wants app scheduling should walk past all three.

What reviewers say
The bottom line
The Mighty2 AP-1512N is the one to buy. It cleans the same size of room as the other two, draws the least power, runs quieter, and its numeric readout makes the auto mode easier to trust. The one trade-off against it is the combined filter, which makes you replace the carbon and HEPA together whether or not both are spent. The AP-1512HH and the 200M are one machine in two cases, and either is reasonable only at a clear discount, with the 200M also giving up the sleep mode. Over years of continuous running the older pair's extra draw shows up on every bill, so the discount has to be large before either of them makes sense.
