Coway AP-1512HH on Amazon · $229.99 →Sold by Amazon.com.
Yes, for a room up to 361 sq ft. At $229.99 it costs less than the newer Mighty2, up front. The catch: it uses more power, and its ratings are Coway's own.
Coway AP-1512HH review
The short answer
Yes. The Coway Airmega AP-1512HH, called the Mighty, is still a good buy for a bedroom or living room up to 361 sq ft. Coway rates it at 233 CFM of smoke clearing on 77 W, and Amazon.com sold it for $229.99 on November 4, 2026. Its filter set is $44.99 a year. The newer Mighty2 is quieter on low (19 dB vs 24 dB), draws 56 W and lists no ionizer, but it costs $40 more, though over two years the Mighty costs about $4 more because it draws more power. One catch: AHAM's directory and ENERGY STAR's list do not include the Mighty, so these are Coway's numbers. If you want certified numbers, the Levoit Vital 200S is certified for 388 sq ft at $189.99.

The Mighty vs the Mighty2 and two certified rivals
Coway rows use Coway's own figures (cowaymega.com, read November 4, 2026); Coway gives the Mighty2's room only at one air change an hour, so its room size is blank. Levoit and Winix rows are AHAM-certified. Quietest setting is the maker's figure. Filter cost is the genuine filter on Amazon for one year. Power cost is running all day on high at 18.83¢ per kWh. Two-year cost = Amazon price + filters you'd buy + two years of power. Amazon prices on November 4, 2026.

The Mighty costs $40 less up front, but more to own over two years ($529 vs $525), because it draws more power. The Winix AT40 costs the least ($358): it draws 45 W and ships with two years of filters.

Frequently asked questions
Is the Coway AP-1512HH still worth it?
Yes, for a room up to 361 sq ft. Coway rates it 233 smoke CADR, and it cost $229.99 on November 4, 2026, $40 less than the Mighty2. A year of genuine filters is $44.99.
Coway Mighty vs Mighty2: is the new one worth it?
Only if quiet and power matter most. Coway rates them about the same (233 vs 240 smoke CADR). The Mighty2 is quieter on low (19 vs 24 dB), draws 56 W instead of 77 W, and uses one filter a year ($69.99). It costs $40 more up front, but about $4 less over two years, because it draws less power.
Does the Coway Mighty have an ionizer?
Yes. Coway's spec list for the AP-1512HH includes "a bipolar device", which is an ionizer. The Mighty2's spec list names only a pre-filter and the Max2 filter (carbon + HEPA), with no ionizer.
Is Coway better than Levoit?
For the same job, they are close. Coway rates the Mighty 233 smoke CADR for 361 sq ft; AHAM certifies the Levoit Vital 200S at 250 for 388 sq ft. On November 4, 2026 the Mighty was $229.99 and the Vital $189.99. The Vital's numbers are certified by AHAM; the Mighty's are Coway's own.
Why does Amazon say 1,748 sq ft when you say 361?
Both are Coway's numbers. 1,748 sq ft is a room it cleans once an hour. 361 sq ft is the room it cleans 4.8 times an hour, the rate AHAM's sizing uses. For smoke, pets or allergies, use 361 sq ft.
How often do you change the Coway AP-1512HH filter?
Coway says the HEPA filter lasts 1 year and the carbon filter 6 months. The genuine set has 1 HEPA and 2 carbon filters, one year's worth: $44.99 on Amazon on November 4, 2026. The best-selling off-brand filter is about $16 a year, $28 less. No lab has tested it; our off-brand filter check weighs when that saving is worth it.
Is the Coway AP-1512HH AHAM certified?
It is not in AHAM's directory of certified purifiers (we checked the list we pulled on October 23, 2026), and it is not on ENERGY STAR's list. Its CADR figures come from Coway's own spec page.
How loud is the Coway AP-1512HH?
Coway lists 24 to 53 dB(A). Low is quiet enough for a bedroom; high is about as loud as a normal conversation.
Sources. CADR, room size, power, noise and filter life are Coway's own figures from its AP-1512HH page, read November 4, 2026. The Mighty is not in AHAM's directory or on ENERGY STAR's list, so no third party certifies these numbers. Average CADR, air changes and clean air per watt are computed by Verified HVAC Data from Coway's figures. We publish no star ratings and take no payment for placement.
