Levoit Core 300S-P Smart Air Purifier
A quiet, efficient 219 ft² bedroom unit sold on a 1051 ft² number and a badge that does not check out.
Wins overall by 0.2 points
Quick Verdict
The Levoit Core 300S-P Smart Air Purifier wins by 0.2 points, which is not enough to settle it. Cheapest filters in the class and an honest coverage table — but check the ioniser button is off. Pick on the specs that matter to you, not the overall score.
The Coway Airmega AP-1512HH Mighty and Levoit Core 300S-P Smart Air Purifier are both closely matched air Purifier models, and the Levoit Core 300S-P Smart Air Purifier is $90 cheaper than the Coway Airmega AP-1512HH Mighty ($149.99 vs $239.99). On Freedom From Ozone & Air Chemistry, the Levoit Core 300S-P Smart Air Purifier leads (10.0 vs 5.0/10) — 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. On Filtration Quality, the Coway Airmega AP-1512HH Mighty leads (8.0 vs 6.5/10) — 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. On Running Cost, the Coway Airmega AP-1512HH Mighty leads (8.0 vs 6.5/10) — 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. Overall, the Levoit Core 300S-P Smart Air Purifier scores 7.1/10 across our 8 scoring categories versus 6.9/10 for the Coway Airmega AP-1512HH Mighty, though the gap is close enough that your specific use case should decide it. Below, we break down the full spec sheet, category-by-category scores, and exactly who should buy which one.
Side-by-Side Comparison
| Spec | Coway Airmega AP-1512HH Mighty | Levoit Core 300S-P Smart Air Purifier |
|---|---|---|
| Price | $239.99 | $149.99 |
| Release Year | 2013 | 2021 |
| AHAM Verifide CADR (Smoke / Dust / Pollen) (CFM) | 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. | Levoit publishes a single combined figure of 141 CFM / 240 m³/h and does not break it into smoke, dust and pollen. NOT independently confirmable: a query of the AHAM Verifide directory in August 2026 returns Levoit models LAP-C171, LAP-C201S, LAP-C311S, LAP-C341S and LAP-P501S, and no entry whose model designation is Core 300S. Levoit's Amazon listing nevertheless carries an "AHAM VERIFIDE" badge. Treat 141 CFM as a manufacturer figure, not a Verifide one. |
| AHAM Verifide Room Size (4.8 ACH) (ft²) | Not listed in the AHAM Verifide directory (August 2026). Coway's own 4.8-ACH figure is 361 ft². | Not listed in the AHAM Verifide directory under this model designation (August 2026). Levoit's own 4.8-ACH figure is 219 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. | Levoit's page states "1051 ft² (1 ACH) / 219 ft² (4.8 ACH)". Levoit deserves credit for printing both; retail listings and round-ups quote the 1051 ft² number on its own. 219 ft² is the number that matters for smoke or pollen. |
| 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. | 3-Stage Original Filter: nylon pre-filter, "HEPA-grade" main media and activated carbon. Levoit's page says HEPA-grade rather than True HEPA or H13; AHAM records HEPA-Type for the neighbouring Core Mini and Core 200S models. |
| Pre-Filter (Washable?) | Yes — permanent washable mesh pre-filter. Coway's instructions: pull it out, rinse or vacuum, dry fully, reset. No recurring cost. | Nylon pre-filter bonded into the replaceable cartridge — not separately washable |
| 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). | $45.00–$60.00/yr with the $29.99 Original filter at the manual's 6–8 month interval; $54.00–$72.00/yr with the $35.99 Pet Allergy or Toxin Absorber filter, $60.00–$80.00/yr with the $39.99 4-Stage Smoke Remover. The product page publishes the prices but not the interval. |
| 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. | None. No ioniser, UV or PCO stage. CARB-certified and classified Mechanical (Levoit "Smart True HEPA Air Purifier" Core 300S, EO G-21-183, notified 2021-05-13). |
| Noise, Lowest to Highest Setting (dB) | 24 dB(A) lowest to 53 dB(A) highest (Coway published) | 22 dB lowest to 50 dB highest (Levoit published) |
| 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. | "AirSight Plus" air-quality scanning. Levoit does not publish the sensing element — it is not described as a laser particle counter anywhere on the product page, unlike Coway's MegaScan or Smartmi's stated laser sensors. Record it as a manufacturer air-quality index rather than a verified PM2.5 measurement. |
| 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. | Wi-Fi and voice control require a VeSync account. The purifier's physical buttons keep working with no internet, but scheduling, air-quality history, remote control and Alexa/Google all stop without the account and the cloud. |
| Power Draw & Annual Energy | 77W maximum (Coway published) | 23W rated. Notably, Levoit rates the non-smart Core 300-P at 56W for an almost identical 143 CFM — a published gap the company does not explain. |
| Warranty Terms & Conditions | 3-year limited warranty per Coway's retail listing; Coway's own product page does not state a term | 2-year limited warranty, 30-day money-back, no registration or subscription condition |
| Warranty | 36 months | 24 months |
| Colors | White, Black | White |
Category Scores
Coverage-Claim Honesty
The Levoit Core 300S-P Smart Air Purifier leads clearly here, 7.5 against 7.0 — a 0.5-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 Coway Airmega AP-1512HH Mighty leads clearly here, 6.5 against 5.5 — a 1.0-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 Levoit Core 300S-P Smart Air Purifier does not close the gap elsewhere.
Filtration Quality
The Coway Airmega AP-1512HH Mighty leads clearly here, 8.0 against 6.5 — a 1.5-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 Levoit Core 300S-P Smart Air Purifier does not close the gap elsewhere.
Running Cost
The Coway Airmega AP-1512HH Mighty leads clearly here, 8.0 against 6.5 — a 1.5-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 Levoit Core 300S-P Smart Air Purifier does not close the gap elsewhere.
Quietness
The Levoit Core 300S-P Smart Air Purifier 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 Levoit Core 300S-P Smart Air Purifier leads clearly here, 5.5 against 5.0 — a 0.5-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 Levoit Core 300S-P Smart Air Purifier leads clearly here, 10.0 against 5.0 — a 5.0-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 Coway Airmega AP-1512HH Mighty leads clearly here, 8.0 against 7.5 — a 0.5-point margin on 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. If that is what you are buying for, the Levoit Core 300S-P Smart Air Purifier does not close the gap elsewhere.

Pros & Cons
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
Levoit Core 300S-P Smart Air Purifier
Pros
- +Levoit prints the 4.8-ACH figure on its own spec table, which most of this field does not
- +22 dB minimum is the equal-quietest here and the display switches fully off
- +23W for 141 CFM is excellent efficiency — and less than half the non-smart Core 300-P's 56W
- +No ioniser, no UV, CARB Mechanical: nothing to remember to switch off
- +Four filter chemistries fit the same body, so you can retune it for smoke or pet odour
Cons
- −The "AHAM VERIFIDE" badge on the retail listing does not correspond to any Core 300S entry in the AHAM directory as of August 2026 — the 141 CFM is a manufacturer figure
- −Levoit publishes one combined CADR and never splits smoke, dust and pollen, so you cannot compare it like-for-like against Winix or Blueair
- −"HEPA-grade" is a deliberately softer claim than True HEPA or H13, and AHAM logs sibling Levoit models as HEPA-Type
- −Smart features are account-gated: no VeSync login means no scheduling, no history, no voice control
- −$149.99 at Levoit is roughly what a 253-CADR Winix or a 246-CADR Coway costs on offer
