Side-by-Side Comparison
| Spec | Levoit Core 300S-P Smart Air Purifier | Blueair Blue Pure 211i Max (3613111100) |
|---|---|---|
| Price | $149.99 | $349.99 |
| Release Year | 2021 | 2023 |
| AHAM Verifide CADR (Smoke / Dust / Pollen) (CFM) | 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: 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. |
| AHAM Verifide Room Size (4.8 ACH) (ft²) | Not listed in the AHAM Verifide directory under this model designation (August 2026). Levoit's own 4.8-ACH figure is 219 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 |
| Coverage Claim & Its Air-Change Basis | 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. | 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. |
| Filter Grade (True HEPA / HEPA-Type / H13) | 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. | 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. |
| Pre-Filter (Washable?) | Nylon pre-filter bonded into the replaceable cartridge — not separately washable | Yes — washable textile pre-filter sleeve, which is also the unit's colour panel. Machine-washable, no recurring cost. |
| Filter Cost per Year | $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. | $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. |
| Ioniser / UV / PCO & CARB Classification | 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). | 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. |
| Noise, Lowest to Highest Setting (dB) | 22 dB lowest to 50 dB highest (Levoit published) | 23 dB lowest to 53 dB highest (Blueair published) |
| Air Quality Sensor | "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. | 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. |
| Smart Features & Offline Operation | 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. | 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. |
| Power Draw & Annual Energy | 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. | 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. |
| Warranty Terms & Conditions | 2-year limited warranty, 30-day money-back, no registration or subscription condition | 1-year standard, extended to 3 years only if you register the product |
| Warranty | 24 months | 12 months |
| Colors | White | Sand, Stockholm Fog, Moss, Limestone |
Category Scores
Coverage-Claim Honesty
The Blueair Blue Pure 211i Max (3613111100) leads clearly here, 8.0 against 7.5 — 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 Levoit Core 300S-P Smart Air Purifier does not close the gap elsewhere.
Verified Clean-Air Delivery
The Blueair Blue Pure 211i Max (3613111100) leads clearly here, 9.5 against 5.5 — a 4.0-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 Blueair Blue Pure 211i Max (3613111100) leads clearly here, 7.5 against 6.5 — a 1.0-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 Levoit Core 300S-P Smart Air Purifier leads clearly here, 6.5 against 5.5 — a 1.0-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 Levoit Core 300S-P Smart Air Purifier and Blueair Blue Pure 211i Max (3613111100) are level here, at 8.0/10 each. 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 is not what separates these two — look to the categories where the scores diverge.
Sensor Quality
The Blueair Blue Pure 211i Max (3613111100) leads clearly here, 8.5 against 5.5 — a 3.0-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 Levoit Core 300S-P Smart Air Purifier 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 6.5 — a 3.5-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 Blueair Blue Pure 211i Max (3613111100) does not close the gap elsewhere.
Controls & Independence
The Blueair Blue Pure 211i Max (3613111100) 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
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
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
