The Levoit Core 300S-P Smart Air Purifier and Winix 5510 (successor to the 5500-2) are both closely matched air Purifier models, and the Levoit Core 300S-P Smart Air Purifier is $110 cheaper than the Winix 5510 (successor to the 5500-2) ($149.99 vs $259.99). On Freedom From Ozone & Air Chemistry, the Levoit Core 300S-P Smart Air Purifier leads (10.0 vs 6.0/10) — 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 Verified Clean-Air Delivery, the Winix 5510 (successor to the 5500-2) leads (9.0 vs 5.5/10) — 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. On Filtration Quality, the Winix 5510 (successor to the 5500-2) leads (8.5 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. Overall, the Winix 5510 (successor to the 5500-2) scores 7.8/10 across our 8 scoring categories versus 7.1/10 for the Levoit Core 300S-P Smart Air Purifier.

Release Year20212024
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 253 / dust 252 / pollen 247 CFM (ahamdir.com, model 5510; the 5520 and 5530 share the identical certification). Genuinely Verifide — Winix is one of the six consumer brands with current directory entries.
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 ft².392 ft² (AHAM Verifide suggested room size at 4.8 air changes per hour)
Coverage Claim & Its Air-Change BasisLevoit'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.Winix leads with "AHAM Verifide 392 ft²" and states the 4.8-ACH basis in a visible footnote, then adds "cleans up to 1,882 ft² in 1 hour" as the secondary figure. That ordering is the right way round and almost nobody else here does it.
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.4-stage: washable fine-mesh pre-filter, AOC pelletised activated-carbon filter, True HEPA rated 99.99% (Winix cites KCL report CT24-072905E under a modified SPS-KACA 002-132:2022 method — note that is a Korean test standard, not EN 1822), and PlasmaWave.
Pre-Filter (Washable?)Nylon pre-filter bonded into the replaceable cartridge — not separately washableYes — washable fine-mesh pre-filter, 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.$55.99–$79.99/yr — Filter Q, part 1712-0123-00, list $79.99 and currently $55.99 direct from Winix, replaced every 12 months. The HEPA and AOC carbon are combined in one part, so that is the whole consumable bill.
Ioniser / UV / PCO & CARB ClassificationNone. 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).Yes — PlasmaWave is a plasma/ion stage. Winix states it "breaks down pollutants at the molecular level without producing harmful ozone" and, to its credit, publishes the measurement: "The 8-hr TWA Ozone for this product is 0.22 ppbv when tested in a 30 m3 chamber." CARB certifies the 5510 as an ELECTRONIC device (EO G-24-234, 2024-10-03) — ozone-capable, tested at or below 0.050 ppm. PlasmaWave has a dedicated on/off control and the unit filters perfectly well with it off.
Noise, Lowest to Highest Setting (dB)22 dB lowest to 50 dB highest (Levoit published)23.5 dB on the slowest of five speeds (Winix published). Winix does not publish a top-speed figure.
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."Dual Smart Sensors" — a particle/air-quality sensor driving a 3-colour LED and auto mode, plus a light sensor that triggers sleep mode when the room darkens. Winix does not state whether the particle sensor is laser-based.
Smart Features & Offline OperationWi-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, the Winix Smart app and Alexa need an account. All five fan speeds, auto mode, sleep mode and the timer work from the top panel with no internet at all — the app is additive, not load-bearing.
Power Draw & Annual Energy23W 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.AHAM-measured 65.0W at the smoke-CADR speed; 323 kWh annual energy consumption per the AHAM listing

Category Scores

Coverage-Claim HonestyThe 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.

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

Winix 5510 (successor to the 5500-2)

Pros

  • +AHAM Verifide 253 smoke CADR — verified performance, not a manufacturer number
  • +Leads with the 392 ft² 4.8-ACH figure and relegates the 1,882 ft² claim to a footnote
  • +Publishes an actual ozone measurement (0.22 ppbv 8-h TWA) rather than just asserting "ozone-free"
  • +One $55.99–79.99 part a year covers HEPA and carbon together; the pre-filter is washable
  • +Works completely offline — every mode is on the panel, the app only adds remote control

Cons

  • PlasmaWave means CARB certifies it as an Electronic (ozone-capable) device; switch it off unless you want it
  • Winix publishes only the 23.5 dB minimum and never the top-speed noise, which at 65W is not quiet
  • 323 kWh/yr on the AHAM listing is the second-highest energy use in this file
  • The 99.99% HEPA claim rests on a Korean KCL test to a modified SPS-KACA method, not EN 1822 or IEST
  • $259.99 direct is well above the street price the outgoing 5500-2 trained buyers to expect
