The Short Answer
Buy Winix if you want the most clean air per dollar, washable filters, and PlasmaWave odor destruction — the 5500-2 and AM90 are the value kings of the mid-size class. Buy Levoit if you want the better app, laser-accurate air sensing, and higher CADR flagships — the Core 400S and 600S win on smart features and verified performance. Neither brand is “better” overall; they win different rooms. Below is the full breakdown so you can match the brand to your situation. (Comparing other brands too?

Brand Overview
Winix is a Korean company that has done almost nothing but air treatment for 50 years. Its purifiers are workhorses: True HEPA filtration, activated carbon, and the proprietary PlasmaWave technology, usually at prices $30–$80 below feature-comparable rivals. The lineup is refreshingly simple — the 5500-2 (and its successor 5510) for medium rooms, the AM90 adding Wi-Fi, and the 9800 for large rooms.
Levoit, owned by California-based VeSync, is the smart-home native. Its Core series (200S, 300S, 400S, 600S) scales cleanly from bedrooms to great rooms, and the VeSync app — with scheduling, air-quality history, and voice control — is the best software in the affordable purifier world. Levoit also publishes unusually transparent CADR data, which makes comparison shopping easy.
Filtration Technology: PlasmaWave vs. 3-Stage H13
This is the real technical divide.
Winix uses a three-part system: a washable fine-mesh pre-filter (catches hair and large dust, extending HEPA life), a True HEPA filter (99.97% at 0.3 microns), an activated-carbon filter for odors — plus PlasmaWave, which generates hydroxyl radicals that chemically break down VOCs, odors, and some bacteria at the molecular level. Carbon can only trap gases; PlasmaWave destroys them. It’s CARB-certified as ozone-safe (below 0.050 ppm), so the old “ionizers make ozone” worry doesn’t apply here.
Levoit uses a classic 3-stage stack: pre-filter, H13 True HEPA (a step above standard True HEPA on paper), and activated carbon. No PlasmaWave equivalent — Levoit’s answer to odors is simply more carbon. In practice, both handle dust, pollen, and dander identically well; Winix has the edge on stubborn household odors (litter boxes, cooking, smoke), while Levoit’s H13 media gives it a slight theoretical edge on ultrafine particles.
For most buyers, the honest takeaway: filtration quality is a wash for particles. Winix wins on odors; Levoit wins on nothing here but loses nothing either.
Model Showdown 1: Winix 5500-2 vs. Levoit Core 400S
This is the matchup most shoppers actually face — two ~$200 purifiers for bedrooms and living rooms.
| Spec | Winix 5500-2 | Levoit Core 400S-P |
|---|---|---|
| Price | ~$150–$200 | ~$200 (recent sales $199.99) |
| CADR smoke / dust / pollen (AHAM) | ~246 / 243 / 269 CFM | 231 / 240 / 259 CFM |
| Room size (AHAM) | 360 sq ft | 358 sq ft (4.8 ACH) |
| Filtration | True HEPA + washable carbon + PlasmaWave | Pre + H13 True HEPA + carbon |
| Noise (min) | 27 dB | 24 dB |
| Smart features | Auto mode, AQ sensor, sleep mode, remote — no Wi-Fi | VeSync app, AirSight Plus laser sensor, Alexa/Google |
| Filter replacement | HEPA ~12 mo, carbon ~3–6 mo (washable) | ~12 mo |
| Rating | Long-running bestseller | 4.7 stars / ~23,000+ ratings |
On raw cleaning they’re near-twins — within 15 CFM of each other on every CADR metric. The decision comes down to extras: the Winix gives you PlasmaWave and a washable carbon filter for less money; the Levoit gives you a superb app, a laser particle sensor with a live PM2.5 display ring, and slightly quieter sleep mode. Our full Levoit Core 400S review digs deeper into that model’s day-to-day experience. For air purifiers for bedrooms where silence and scheduling matter, the Levoit edges ahead; for odor-heavy rooms, the Winix.
Model Showdown 2: Winix AM90 vs. Levoit Core 400S
The AM90 is Winix’s answer to the “but I want an app” objection: it takes the 5500-2’s cleaning core and adds Wi-Fi, the Winix Smart app, Alexa voice control, and an air-quality monitor — typically for $180–$230, or about $30–$50 over the 5500-2.
Against the Core 400S at ~$200, it’s a genuine toss-up. The AM90 counters with PlasmaWave and the washable filter; the Levoit counters with the better app and laser sensing. If you want Winix cleaning with smart control and don’t want to pay the Levoit premium for software polish, the AM90 is arguably the best-value smart purifier under $250.
Model Showdown 3: Large Rooms — Winix 9800 vs. Levoit Core 600S
Stepping up to genuinely large rooms, the Levoit Core 600S pulls ahead decisively: AHAM-verified 391 CFM smoke CADR (vs. ~323 CFM for the Winix 9800), 606 sq ft of AHAM-rated coverage, and the full VeSync/AirSight smart package for ~$300. The Winix 9800 (~$240–$300) is still a fine large-room unit with 4-stage filtration and Wi-Fi, but the 600S simply moves more air — and in large rooms, airflow is everything. See our guide to the best air purifiers for the full large-room rankings.
Smart Features and App Quality
Levoit wins clearly. The VeSync app offers remote control, detailed scheduling, air-quality trend graphs, filter-life tracking, and Alexa/Google integration — and it’s stable. The AirSight Plus laser sensor (on the 400S and 600S) measures PM2.5 more accurately than the infrared sensors in most competitors, and the color ring display makes air quality glanceable.
Winix’s app covers the basics — remote control, scheduling, filter alerts — and the AM90/9800 add Alexa voice control, but the software feels a generation behind VeSync. The 5500-2 has no connectivity at all (physical controls + remote only), which is fine if you just want clean air without another app.
Noise Levels
Both brands are quiet where it counts. Minimum noise: Levoit Core 400S 24 dB, Core 600S 26 dB, Winix 5500-2/AM90 27 dB, Winix 9800 26.2 dB — all whisper-quiet on sleep/low. On high, both reach the low-to-mid 50s dB (normal conversation level). Neither brand has a meaningful noise advantage; size the unit correctly so it rarely needs high speed.
Filter Costs and Maintenance
- Winix: ~$50–$70/year. The washable pre-filter and washable carbon filter (5500-2/AM90) are genuine money-savers, especially in pet homes where hair would otherwise clog a disposable pre-filter. True HEPA lasts ~12 months.
- Levoit: ~$50–$100/year depending on model. No washable pre-filter on most models, but the Core 600S’s filter stretches to ~12 months, and Levoit’s replacement filters are widely available and reasonably priced.
Over five years, Winix’s washable filters save roughly $100–$150 — not life-changing, but real.
Price and Value
| Model | Typical price | Price per 100 CFM smoke CADR |
|---|---|---|
| Winix 5500-2 | ~$150–$200 | ~$65–$80 |
| Winix AM90 | ~$180–$230 | ~$75–$95 |
| Levoit Core 400S-P | ~$200 | ~$87 |
| Levoit Core 600S | ~$300 | ~$77 |
| Winix 9800 | ~$240–$300 | ~$75–$95 |
Winix wins the value math in the mid-size class; Levoit wins it at the large-room flagship level. Both brands discount regularly — rarely pay list price.

FAQ
Is Winix or Levoit better for allergies?
Both are excellent — allergies respond to HEPA particle removal, and both brands’ HEPA filters capture 99.97% of pollen, dust-mite debris, and dander. Pick by room size and features, not brand: either the Winix 5500-2/AM90 or Levoit Core 400S will serve a bedroom well.
What is PlasmaWave, and is it safe?
PlasmaWave is Winix’s technology that creates hydroxyl radicals from ambient humidity to break down odors, VOCs, and some bacteria. All Winix PlasmaWave models are CARB-certified as ozone-safe (below 0.050 ppm), so it doesn’t produce harmful ozone levels.
Does the Winix 5500-2 have Wi-Fi?
No. The 5500-2 uses physical controls plus a remote. If you want Winix cleaning with app and Alexa control, step up to the AM90.
Which is quieter, Winix or Levoit?
Effectively tied. Both start at 24–27 dB on their lowest settings (quieter than a whisper) and reach the low–mid 50s dB on high. Buy the right size so the unit can stay on low.
How do Winix and Levoit compare on filter costs?
Winix runs ~$50–$70/year thanks to washable pre-filters and carbon filters; Levoit runs ~$50–$100/year with fully disposable filters. Winix saves roughly $100–$150 over five years.
Is Levoit a Chinese company?
Levoit is a brand of VeSync, a company headquartered in California with manufacturing in China — the same arrangement as many US-sold appliance brands. Winix is headquartered in South Korea. Both sell and support their products fully in the US.
Final Verdict
Winix vs Levoit isn’t a knockout — it’s a split decision. Winix wins on value and odor control: the 5500-2 and AM90 deliver AHAM-verified cleaning, PlasmaWave, and washable filters for less money than anything comparable. Levoit wins on smarts and flagship power: the VeSync app and AirSight laser sensing are genuinely better, and the Core 600S is the stronger large-room machine. Match the brand to your priority — odors and budget go Winix, apps and max CADR go Levoit — and you’ll end up with the right purifier.
