Air Purifiers / Coway
Coway Airmega AP-1512HH Mighty
Cheapest filters in the class and an honest coverage table — but check the ioniser button is off.
Overall score 6.9/10
Pros
- + Coway publishes a three-rung coverage ladder — 1,748 / 874 / 361 ft² — instead of hiding the 4.8-ACH figure
- + $54.99 buys a complete year of filters, the cheapest running cost of any 200-plus-CADR unit here
- + Washable permanent pre-filter genuinely removes a consumable rather than renaming one
- + Completely offline: no account, no app, no firmware, nothing to be discontinued
- + 3-year warranty and a decade of continuous production behind the design
Cons
- − Coway is not in the AHAM Verifide directory at all in August 2026, so the 233/246/240 CADR is self-reported
- − The fourth stage is a bipolar ioniser and CARB classifies this model as an Electronic device — ozone-capable, certified only as under 0.050 ppm. Switch it off
- − The air-quality sensor is a dust sensor, not the laser PM sensor Coway put in the Mighty2 successor
- − 77W is the second-highest draw here for a mid-size unit
- − No Wi-Fi, no scheduling, no filter-life telemetry — you watch an indicator light
Coway Airmega AP-1512HH Mighty review: what the specs say
Cheapest filters in the class and an honest coverage table — but check the ioniser button is off. At $239.99, Coway's 2013 model sits in the middle of the range — the air Purifiers we compare run from $49.99 to $1,014.99. It scores 6.9/10 overall, calculated from published specifications across 8 categories rather than from a subjective impression.
Its strongest showing is Filtration Quality at 8.0/10 — what the media is really rated at — sealed H13, True HEPA, HEPA-Type, EPA 12 or charged fabric — whether the whole machine is sealed so air cannot bypass the filter, and how much genuine activated carbon there is for odours and VOCs. The weakest is Freedom From Ozone & Air Chemistry at 5.0/10, which is the trade-off to weigh before buying: if that is the specification you care about most, one of the alternatives below will serve you better.
Worth knowing before you buy: coway is not in the AHAM Verifide directory at all in August 2026, so the 233/246/240 CADR is self-reported; and the fourth stage is a bipolar ioniser and CARB classifies this model as an Electronic device — ozone-capable, certified only as under 0.050 ppm. Switch it off. Every specification on this page comes from Coway's own documentation or a verified retail listing — where a figure is not published, the table says so rather than estimating it.

Full Specifications
| AHAM Verifide CADR (Smoke / Dust / Pollen) | Coway publishes smoke 233 / dust 246 / pollen 240 CFM itself. NOT AHAM Verifide as of August 2026: Coway does not appear in the AHAM Verifide directory's brand index at all, so no Coway model — including this one — currently carries a Verifide CADR. These are manufacturer figures. CFM |
| AHAM Verifide Room Size (4.8 ACH) | Not listed in the AHAM Verifide directory (August 2026). Coway's own 4.8-ACH figure is 361 ft². ft² |
| Coverage Claim & Its Air-Change Basis | Coway's own spec table gives "1 air change/hr 1,748 ft² / 2 air changes/hr 874 ft² / 4.8 air changes/hr 361 ft²" — the most complete ladder any brand here publishes. The retail listing headline is the 1,748 ft² number. |
| Filter Grade (True HEPA / HEPA-Type / H13) | Four stages: washable pre-filter, deodorisation (activated carbon) filter, True HEPA filter rated 99.97% at 0.3 µm, and a bipolar ionising device. Coway calls the HEPA stage True HEPA; the newer Mighty2 is marketed as "IEST certified HEPA" instead. |
| Pre-Filter (Washable?) | Yes — permanent washable mesh pre-filter. Coway's instructions: pull it out, rinse or vacuum, dry fully, reset. No recurring cost. |
| Filter Cost per Year | $54.99/yr — Airmega Mighty AP-1512HH & 200M filter set (SKU 3304899 / 3109905 / 3118096) contains one HEPA filter (1-year life) and two deodorisation filters (6-month life), i.e. exactly one year of consumables. Specialty sets run $54.99–$56.99 (Intense Smoke, Allergen, Pet). |
| Ioniser / UV / PCO & CARB Classification | Yes — the fourth stage is a bipolar ionising device, and it is listed in Coway's own filter composition. CARB records the AP-1512HH as an ELECTRONIC device (Coway/Woongjin Coway, EO G-13-027 and G-16-011), meaning it is capable of generating ozone and was certified only because it tested at or below 0.050 ppm. The revised AP-1512HHC (EO G-25-347) and the Mighty2 AP-1512N (G-26-042) are certified as Mechanical. The ioniser has its own button and can be switched off. |
| Noise, Lowest to Highest Setting | 24 dB(A) lowest to 53 dB(A) highest (Coway published) dB |
| Air Quality Sensor | Coway calls it a "dust sensor" on this model and does not describe it as a laser particle counter. The successor Mighty2 upgrades to a "MegaScan laser sensor (PM1, 2.5, 10)" — which tells you what the AP-1512HH's sensor is not. |
| Smart Features & Offline Operation | None on this SKU. No account, no app, no cloud, no firmware; every function is on the top panel. That makes it the most future-proof mid-range unit here. |
| Power Draw & Annual Energy | 77W maximum (Coway published) |
| Warranty Terms & Conditions | 3-year limited warranty per Coway's retail listing; Coway's own product page does not state a term |
| Connectivity | None on the AP-1512HH — no Wi-Fi, no app; the AP-1512HHS and the newer Mighty2 AP-1512N add it |
| Material | Not published by Coway — the spec table lists no housing material |
| Warranty | 36 months |
