Short answer
Watch the Coway Airmega Mighty2 (Wirecutter’s 2026 top pick), the original Mighty AP-1512HH if they want the longer test record, and the Levoit Core 400S for app control and ENERGY STAR numbers. Ignore giant square-footage claims. Verdicts land the week of Nov 20.
How we researched this
We did not test these purifiers in person. Models come from our air purifier guide. How we judge a deal: we compare a listing against public Amazon price-history trackers such as camelcamelcamel (Amazon-sold prices, not third-party marketplace highs). On November 8, 2026 we requested camelcamelcamel US charts for the ASINs below; the chart images and product pages returned Cloudflare challenges from our research machine, so we are not inventing chart shapes or printing dollar prices. Use the live “check price” buttons and the linked camelcamelcamel pages yourself. A real deal is a cut toward the tracker’s long Amazon-sold low, sold and shipped by Amazon or the brand, on the exact model testers reviewed—not a list-price “% off” badge. Final verdicts land the week of Nov 20. Last updated November 8, 2026.
Deal status: Verdicts checked Nov 8, 2026, 8 AM CT (pre-sale baseline). Final verdicts the week of Nov 20.
Quick verdict: which air purifier deals are worth waiting for?
🏅 DudProof Pick: Coway Airmega Mighty2 (AP-1512N). A DudProof Pick is the product the evidence says is least likely to be a dud for most people. What our badges mean
All three models come from our air purifier guide. Size them for roughly 350–370 square feet at a useful air-change rate—not the “1,800 sq ft in 60 minutes” marketing line.

The air purifiers worth buying on sale
Coway Airmega Mighty2 (AP-1512N)
Verdict coming the week of Nov 20. Pre-sale read: We requested camelcamelcamel B0GS7FF1D6 on November 8, 2026; the chart was Cloudflare-blocked from our research machine.
What a real deal looks like: a clear cut toward the camelcamelcamel Amazon-sold low (or repeated lower band) on the exact model below, sold and shipped by Amazon or the brand—not a list-price “% off” badge and not a third-party marketplace markup.
Why it’s worth watching: Wirecutter’s 2026 top pick, replacing the original Mighty. Coway rates it at 56 W, lower than the original Mighty’s 77 W. Newer model, so less long-term owner history; it was not on the ENERGY STAR V3.0 list as of our Nov 1, 2026 check.
Model check: The title should say Mighty2 or AP-1512N—not a different Airmega tower.
Room-size math and running-cost notes: best air purifiers.
Coway Airmega Mighty (AP-1512HH)
Verdict coming the week of Nov 20. Pre-sale read: We requested camelcamelcamel B01728NLRG on November 8, 2026; the chart was Cloudflare-blocked.
What a real deal looks like: a clear cut toward the camelcamelcamel Amazon-sold low (or repeated lower band) on the exact model below, sold and shipped by Amazon or the brand—not a list-price “% off” badge and not a third-party marketplace markup.
Why it’s worth watching: Choose it if they want the longer test record and will switch the ionizer off. It may be harder to find as Coway shifts to the Mighty2.
Model check: Match AP-1512HH. Switch the ionizer off if they want zero added ozone.
The proven classic on the same guide: a Wirecutter pick from 2015 to 2026. HouseFresh measured fast smoke clearing (26 minutes with the ionizer on, 29 with it off) and 9 ppb ozone with the ionizer on.
Levoit Core 400S
Verdict coming the week of Nov 20. Pre-sale read: We requested camelcamelcamel B08R794ZMX on November 8, 2026; the chart was Cloudflare-blocked.
What a real deal looks like: a clear cut toward the camelcamelcamel Amazon-sold low (or repeated lower band) on the exact model below, sold and shipped by Amazon or the brand—not a list-price “% off” badge and not a third-party marketplace markup.
Why it’s worth watching: Best if they want an app and published certification numbers. HouseFresh found the bonded pre-filter clumsy to clean and noted Levoit dropped “HEPA H13” language after a Dyson BBB complaint.
Model check: Match Core 400S (U.S. version). It is not the Core 300 or Vital 200S.
HouseFresh measured the fastest clean-up of the three (24 minutes, U.S. version) and 0 ppb ozone. ENERGY STAR certified. Filter costs add up (HouseFresh cited about two filter sets a year).
Fake-deal patterns to ignore
- Square-footage fantasy. “Cleans 1,800 sq ft” usually means one air change per hour. For smoke and allergies, size closer to five air changes—about 350–370 sq ft for these CADR numbers.
- Wrong Coway or Levoit generation. Mighty2 ≠ Mighty ≠ a tall Airmega. Core 400S ≠ Core 300.
- Filter-less “miracle” gadgets or ionizer-only plates sold as purifiers.
- List-price % off without a camelcamelcamel Amazon-sold check.
How to check any air-purifier deal yourself
- Match the exact model number (AP-1512N, AP-1512HH, Core 400S).
- Paste the ASIN into camelcamelcamel and read the Amazon-sold chart.
- Check that replacement filters are still sold by the brand.
- Treat CADR and ENERGY STAR figures as more trustworthy than room-size marketing.
- Wait for our week-of-Nov-20 verdict if you can.
Dud Alert: recalls to check
Our Nov 1, 2026 CPSC check found no recalls of the Mighty2, original Mighty or Core 400S. Still match model numbers, and remember the original Mighty’s ionizer is switchable.
| Date | Recall | Hazard | Check |
|---|---|---|---|
| Nov 1, 2026 | No CPSC recalls found on these three exact models (buying-guide database check) | — | See the air purifier guide comparison table |
FAQ
When will Dudproof post final air-purifier verdicts?
The week of November 20, 2026. This page is a pre-sale baseline only.
Is the Coway Mighty2 the same as the original Mighty?
No. Mighty2 is AP-1512N (Wirecutter’s 2026 top pick). The original Mighty is AP-1512HH, with a longer test record and a switchable ionizer.
Should I buy a purifier just because the square-footage number is huge?
No. Use CADR and a roughly 5-air-change target. These three are bedroom/living-room machines, not whole-open-floor plans.
Do you print Black Friday prices here?
No. We link camelcamelcamel and live Amazon prices.
Are these purifiers tested by Dudproof?
No. Evidence comes from Wirecutter, HouseFresh, ENERGY STAR, EIA math and CPSC records cited on our buying guide.
