Desk research only. No hands-on testing was performed by Filter Math. All social evidence is paraphrased, never quoted verbatim. Health-adjacent claims appear only as attributed owner/reviewer accounts, never as proven medical efficacy. Marketplace prices are asking prices, not completed sales. All time-sensitive facts and prices dated 2026-09-23 unless otherwise noted. UNVERIFIED marks facts that could not be confirmed from a recovered source. Seed-file attributions (market-selection file) were treated as leads, not citations; claims from it were not reused without independent recovery.
1. Disclosure
This dossier was built from Coway's official pages, independent tester comparisons (overeview, airpurifiershub), and spec aggregators, observed 2026-09-23, plus direct social-tool observations. Social discovery was attempted via Threads CLI, Facebook CLI, and Instagram CLI on 2026-09-23. One Facebook Marketplace listing for this model was directly observed (see Section 3). Where the seed market-selection file named a source without a URL, that claim was treated as a lead and is not cited here unless independently recovered (see private source ledger _source-ledger.md, which never ships).
2. Overview / current version
The AP-1512HH "Mighty" is Coway's long-running mid-size benchmark: strong CADR (233/246/240), a three-stage system (washable pre-filter, deodorization filter, HEPA) with an optional ionizer feature, auto/eco/timer modes and a PM sensor — but no app or Wi-Fi. It is the unit other mid-size purifiers are measured against in editorial content, and the direct predecessor of the Airmega Mighty2 (AP-1512N).
3. Social standing & validation tier
UNVALIDATED — included for comparison, low community signal.
- One direct social observation: facebook-cli marketplace search (2026-09-23) returned a listing titled "Coway Air Purifier AP-1512HH + New Filters", used/good condition, bundled with a new filter pack (2 HEPA + 6 carbon), asking $120, in Goleta, CA, listed 2026-09-20 (listing ID 28523661783955104). Asking price, not a completed sale — one attributable item, not two. Tier unchanged.
- The Threads search in this session returned one Coway-related post (May 2025, Malay-language) regretting a 7-year Coway rental commitment — a rental-model complaint, not Mighty-specific; paraphrased, minimal engagement. Not counted as product evidence.
- No Facebook owner-group posts or Instagram posts specific to the AP-1512HH were directly observed (Facebook groups search failed with a connector grant error — access failure, not no-results).

Cross-check (overeview head-to-head, updated ~Aug 2026): lists the Mighty at ~$160 with 246/233/240 CADR, 360 ft², 24/53 dB, filter ~$30–40/yr, and notes eco mode fully stops the fan (vs. Levoit's slow-to-minimum). (source: https://overeview.com/levoit-vs-coway-air-purifier/) Cross-check (airpurifiershub comparison table, observed 2026-09-23): lists the Mighty at $229.99, smoke CADR 233, no app, annual filter $66.00, sleep-mode 28 dB. (source: https://airpurifiershub.com/levoit-core-400s-review/)
5. Price observed 2026-09-23
- $239.99 — official price, cowaymega.com (observed 2026-09-23).
- Comparison sites show lower street figures (~$160 per overeview, ~Aug 2026; $229.99 per airpurifiershub) — treat as tester-listed, not confirmed current retail.
- Used asking price: $120 with new filters (Marketplace, Goleta CA, listed 2026-09-20) — asking price only.
6. Annual filter cost
- Conflicted — preserved as found:
- ~$48/yr estimated (one source)
- $64.99 current genuine filter set (Coway's filter collection, observed 2026-09-23)
- $66.00/yr (airpurifiershub table)
- ~$30–40/yr (overeview)
- The filter schedule (deodorization 6 mo + HEPA 12 mo) means annual cost depends on whether the deodorization filter is replaced on schedule. No single reconciled figure — UNVERIFIED as a consensus.
7. Included / needed
- In the box (per Coway's page): purifier with filter set installed. No app to set up. Replacement deodorization + HEPA filters are the recurring need; the ionizer feature is optional and can be left off.
8. Support & warranty
- UNVERIFIED in the documented sample.
9. Attributed owner / reviewer complaints
- No app/Wi-Fi is the standard reviewer criticism of a unit that otherwise benchmarks well.
- Turbo noise (53 dB top end) is the recurring practical complaint pattern in roundups.
- No defect-cluster or support-dispute data specific to the AP-1512HH was recovered in the documented sample.
10. Cross-brand comparison notes
- HouseFresh's Airmega Mighty2 review (URL recovered: https://housefresh.com/coway-airmega-mighty2-ap-1512n-review/; page open timed out in this session — access failure, so the comparator list is taken from the shared source ledger's recovery note, not re-verified here) names the original Mighty AP-1512HH, the Levoit Vital 200S, and the Winix 5510/5520 as tested comparators, with the Mighty2 outperforming them in HouseFresh's tests. This is the most current attributed cross-brand comparator touching the Mighty — but note the caveat: the exact comparator set could not be re-verified by direct page read in this session.
- In the documented sample, the Mighty is the "no-app benchmark": rivals (Winix 5510, Levoit Core 400S) compete by adding smart features at similar CADR.
11. Community verdict
The Mighty's benchmark status is editorial, not owner-observed in this session: one used listing and no owner conversations recovered. The filter-cost conflict ($30–66/yr across sources) is the main thing a buyer should pin down, and the Mighty2's arrival makes the original Mighty a "buy on discount" proposition.
