Side-by-Side Comparison
| Spec | Blueair Blue Pure 211i Max (3613111100) | Coway Airmega AP-1512HH Mighty |
|---|---|---|
| Price | $349.99 | $239.99 |
| Release Year | 2023 | 2013 |
| AHAM Verifide CADR (Smoke / Dust / Pollen) (CFM) | AHAM Verifide: smoke 435 / dust 453 / pollen 450 CFM (ahamdir.com, model 3613111100, listed as "Pure Blue 211i Max"). The highest Verifide CADR in this file. Note that AHAM records this model's filter type as "Fabric", not HEPA. | 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. |
| AHAM Verifide Room Size (4.8 ACH) (ft²) | 674 ft² (AHAM Verifide suggested room size at 4.8 air changes per hour) — and Blueair publishes exactly 674 ft² at 4.8 ACH on its own page | Not listed in the AHAM Verifide directory (August 2026). Coway's own 4.8-ACH figure is 361 ft². |
| Coverage Claim & Its Air-Change Basis | Blueair's own product page leads with "674 sq ft" and "4.8 air changes per hour", which is the correct figure correctly labelled. The retail listing title, by contrast, says "Large Rooms up to 3,235 Sq Ft" — that is 674 × 4.8, i.e. the 1-ACH number. Same product, two claims a factor of 4.8 apart. | 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) | HEPASilent: a two-part system that electrostatically charges particles before a loosely woven fabric media collects them, plus activated carbon. Blueair claims 99.97% of airborne particles. It is not a mechanical H13 filter and AHAM logs the filter type as "Fabric" — the efficiency comes from the charging stage as much as the media. | 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 — washable textile pre-filter sleeve, which is also the unit's colour panel. Machine-washable, no recurring cost. | 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 | $79.99–$93.32/yr — Particle & Carbon Filter $69.99 ($59.50 on subscription) with Blueair's RealTrack algorithm calling replacement at up to 9 months, i.e. about 1.33 filters a year. The AllergenBlock variant is $89.99 ($76.50) and SmokeBlock $84.99 ($72.25), pushing it to $100–120/yr. | $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 | HEPASilent's ion-charging stage is integral to how the unit filters and CANNOT be switched off — unlike the Coway ioniser or Winix PlasmaWave, there is no button. CARB certifies the Blue Pure 211i Max as an ELECTRONIC device (Blueair AB, EO G-23-076, notified 2023-04-19), meaning ozone-capable and tested at or below 0.050 ppm. Blueair's product page makes no ozone statement at all. Every Blueair model in the CARB list is classified Electronic. | 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 (dB) | 23 dB lowest to 53 dB highest (Blueair published) | 24 dB(A) lowest to 53 dB(A) highest (Coway published) |
| Air Quality Sensor | Genuine multi-channel particulate sensing: PM1, PM2.5 and PM10, feeding auto mode and the app's history. One of only three units here that resolve PM1. | 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 | Wi-Fi and the Blueair app require an account. Fan speed, auto mode and night mode all work from the physical dial with no internet; filter tracking, air-quality history and scheduling do not. | 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 | 46W (Blueair published); AHAM-measured 44.0W at the smoke-CADR speed and 256 kWh annual energy consumption. That is 435 CFM of smoke CADR for 44W — comfortably the best clean-air-per-watt here. | 77W maximum (Coway published) |
| Warranty Terms & Conditions | 1-year standard, extended to 3 years only if you register the product | 3-year limited warranty per Coway's retail listing; Coway's own product page does not state a term |
| Warranty | 12 months | 36 months |
| Colors | Sand, Stockholm Fog, Moss, Limestone | White, Black |
Category Scores
Coverage-Claim Honesty
The Blueair Blue Pure 211i Max (3613111100) leads clearly here, 8.0 against 7.0 — a 1.0-point margin on the trap dimension for this category. Almost every brand derives its headline square footage from ONE air change per hour, which does close to nothing for smoke, pollen or wildfire particulate — the useful standard is 4.8 air changes an hour, and it is typically a fifth of the number on the box. A high score means the manufacturer publishes the 4.8-ACH figure prominently and it survives comparison with the AHAM Verifide room size; a low score means a big number with no stated air-change basis, or no CADR at all to derive one from.. If that is what you are buying for, the Coway Airmega AP-1512HH Mighty does not close the gap elsewhere.
Verified Clean-Air Delivery
The Blueair Blue Pure 211i Max (3613111100) leads clearly here, 9.5 against 6.5 — a 3.0-point margin on how much air the unit actually cleans per minute, weighted heavily toward AHAM Verifide smoke CADR over manufacturer-published figures. Self-reported CADR scores below Verifide CADR, and 'no CADR published at all' scores below both. If that is what you are buying for, the Coway Airmega AP-1512HH Mighty does not close the gap elsewhere.
Filtration Quality
The Coway Airmega AP-1512HH Mighty leads clearly here, 8.0 against 7.5 — a 0.5-point margin on 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. If that is what you are buying for, the Blueair Blue Pure 211i Max (3613111100) does not close the gap elsewhere.
Running Cost
The Coway Airmega AP-1512HH Mighty leads clearly here, 8.0 against 5.5 — a 2.5-point margin on filters, pre-filters, cartridges and subscriptions over three years, against the purchase price. Several units here cost more to feed than to buy; a high score means cheap, long-lived, non-proprietary consumables. If that is what you are buying for, the Blueair Blue Pure 211i Max (3613111100) does not close the gap elsewhere.
Quietness
The Blueair Blue Pure 211i Max (3613111100) leads clearly here, 8.0 against 7.5 — a 0.5-point margin on measured decibels at the lowest setting you would run overnight AND at the top speed you need in a smoke event — a purifier is only useful at a speed you can tolerate. Not publishing a figure at either end costs points. If that is what you are buying for, the Coway Airmega AP-1512HH Mighty does not close the gap elsewhere.
Sensor Quality
The Blueair Blue Pure 211i Max (3613111100) leads clearly here, 8.5 against 5.0 — a 3.5-point margin on whether there is a real laser particle sensor resolving PM1/PM2.5/PM10 with numeric output, a vaguer 'air quality' index, an inference from a cheap VOC element, or no sensor and therefore no auto mode at all. If that is what you are buying for, the Coway Airmega AP-1512HH Mighty does not close the gap elsewhere.
Freedom From Ozone & Air Chemistry
The Blueair Blue Pure 211i Max (3613111100) leads clearly here, 6.5 against 5.0 — a 1.5-point margin on whether the unit adds an ioniser, plasma, UV or photocatalytic stage to the airstream, whether that stage can be switched off, and how CARB classifies the device — 'Mechanical' means filtration only, 'Electronic' means capable of generating ozone and certified only as being at or below 0.050 ppm. If that is what you are buying for, the Coway Airmega AP-1512HH Mighty does not close the gap elsewhere.
Controls & Independence
The Blueair Blue Pure 211i Max (3613111100) and Coway Airmega AP-1512HH Mighty are level here, at 8.0/10 each. whether every mode works from the machine itself with no account or cloud, how good the auto mode is, filter-change access, and whether losing a remote or a login costs you function is not what separates these two — look to the categories where the scores diverge.

Pros & Cons
Blueair Blue Pure 211i Max (3613111100)
Pros
- +435 CFM AHAM Verifide smoke CADR — the most verified clean air of anything here at any price
- +44W for that output is the best efficiency in this file by a wide margin
- +Blueair's own page leads with the honest 674 ft² at 4.8 ACH, not the 3,235 ft² retail headline
- +23 dB minimum with real PM1/PM2.5/PM10 sensing driving auto mode
- +Washable fabric pre-filter doubles as the colour panel, so it costs nothing to maintain
Cons
- −The HEPASilent ion-charging stage cannot be turned off — CARB classifies the unit as an Electronic (ozone-capable) device and Blueair makes no ozone statement on the page
- −AHAM records the filter type as "Fabric": this is charged-media filtration, not a mechanical H13 element
- −The retail listing's "up to 3,235 Sq Ft" is Blueair's own 674 ft² multiplied by 4.8 — a 1-ACH number
- −1-year warranty unless you register, and even then 3 years is short next to Honeywell's 5
- −$69.99–$89.99 filters at up to 9 months is $80–120/yr, twice the Coway's $54.99
Coway Airmega AP-1512HH Mighty
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
