Levoit and Winix are two of the most popular air purifier brands in the United States, and they take very different approaches to clean air. Levoit builds sleek, cylindrical purifiers around its VeSync smart app, laser particle sensors, and whisper-quiet sleep modes. Winix builds boxy workhorses around True HEPA filtration, washable carbon filters, and PlasmaWave — and nearly every Winix model carries independent AHAM verification.
So which brand should you buy? The short answer: Levoit wins on smart features, app control, and quiet bedrooms, while Winix wins on verified cleaning power per dollar, odor control, and long-term filter costs. The right pick depends on your room size, your allergies, and whether you want an app.
Levoit vs Winix at a Glance
Both brands use True HEPA filtration that captures 99.97% of airborne particles as small as 0.3 microns. The differences show up in how they filter, sense the air, and what filters cost over time.

Head-to-Head: The Best Models Compared
| Model | CADR (smoke / dust / pollen) | Room Coverage | Noise | Filter Type |
|---|---|---|---|---|
| Levoit Core 300 | 143 / 153 / 167 CFM | About 222 sq ft at 4.8 ACH | 24 dB sleep, up to about 50 dB | 3-in-1 H13 True HEPA + carbon |
| Levoit Core 400S | 231 / 240 / 259 CFM | 403 sq ft marketed; about 358 sq ft at 4.8 ACH | 24–52 dB | 3-stage H13 True HEPA + carbon |
| Levoit Vital 200S | 250 / 254 / 289 CFM | About 380–390 sq ft at 4.8–5 ACH | 24–54 dB | 3-stage HEPA + washable pre-filter |
| Winix 5500-2 | 232 / 243 / 246 CFM | 360 sq ft | 27.8 dB low, up to about 56 dB | True HEPA + washable AOC carbon + PlasmaWave |
| Winix 9800 | AHAM Verifide at 500 sq ft | 500 sq ft AHAM; up to 2,420 sq ft in 1 hour | 26.2 dB | True HEPA + carbon + PlasmaWave |
| Winix C545 | 232 / 243 / 246 CFM | 360 sq ft | About 28 dB low | True HEPA + carbon sheets + PlasmaWave |
A note on room coverage: manufacturers quote their biggest number, usually at just one air change per hour. The honest comparison is the AHAM room size at about 4.8 air changes per hour, the rate allergy guidance generally targets. That is why the Core 400S is marketed at 403 sq ft but its AHAM-verified coverage works out to roughly 358 sq ft, and why the Winix 9800’s headline of 2,420 sq ft in one hour sits next to its AHAM-verified room size of 500 sq ft. Size your purifier by CADR and the AHAM room size, not by the headline on the box.
Key Differences Between Levoit and Winix
Filtration: 3-stage simplicity vs. 4-stage odor control
Most Levoit models use a single 3-in-1 cartridge that combines a pre-filter, an H13 True HEPA filter, and an activated carbon layer. Swapping it takes seconds, but you replace the whole cartridge every 6 to 8 months, which adds up.
Winix uses a 4-stage system: a washable pre-filter, a True HEPA filter, a carbon filter, and PlasmaWave, its ion-based technology for breaking down odors and volatile organic compounds. On the 5500-2, the AOC carbon filter is washable and never needs replacing — only the HEPA filter gets swapped, about once a year. That makes Winix cheaper to run over three to five years, and stronger on cooking smells, pet odors, and smoke.
Smart features: Levoit leads, Winix is catching up
This is Levoit’s clearest win. The Core 400S and Vital 200S connect to the VeSync app, work with Alexa and Google Assistant, and adjust themselves automatically using a laser PM2.5 sensor. The Vital 200S adds a dual PM2.5 and VOC sensor, so it reacts to gases and odors as well as dust, and you can schedule runtimes and check air quality from your phone.
Winix has closed much of the gap: the 5510, C545, and 9800 offer WiFi and the Winix Smart app. But the classic 5500-2 has no app at all — just a remote and an air quality light. If smart-home control matters, Levoit is the safer bet.
Noise: Levoit is quieter at the low end
Both brands are bedroom-friendly, but Levoit edges ahead. The Core 300 and Core 400S both drop to 24 dB in sleep mode, which is quieter than a whisper. Winix models start a little higher — about 26.2 dB on the 9800 and 27.8 dB on the 5500-2 — a difference you can hear in a dead-quiet room, though both are easy to sleep next to. At full speed, both brands get loud: roughly 50–56 dB from the Levoits and up to about 56–60 dB from the Winix models.
Room coverage and cleaning power
At the budget end, Levoit wins: the Core 300’s AHAM-verified CADR of 143 CFM for smoke covers about 222 sq ft, and nothing from Winix competes at that size and price. In the mid-range, the two brands are nearly tied — the Core 400S posts 231 CFM for smoke against the 5500-2’s 232 CFM, and both cover roughly 360 sq ft. If you are torn between the two classic mid-range rivals, our Winix vs Coway comparison breaks down the 5500-2 against the Coway Mighty. At the top end, Winix pulls ahead: the 9800 is AHAM Verifide for 500 sq ft rooms. For most homes, the practical difference is small — buy the model sized to your room, whichever brand it comes from.
Filter costs and maintenance
Winix wins on running costs. Washable pre-filters and washable carbon filters mean fewer replacements, and the HEPA filter on the 5500-2 lasts about 12 months. Winix has also committed to making replacement filters for the discontinued 5500-2 through 2032. Levoit’s all-in-one cartridges are more convenient to swap but need replacing every 6 to 8 months, so budget for two filters a year. The Vital 200S softens this with a washable pre-filter.

Which Is Better for Whom?
Choose Levoit if you want a smart, quiet bedroom purifier. The Core 300 is one of the best air purifiers for a small bedroom, and the Core 400S is the pick if you want app control, schedules, and a laser sensor that adjusts the fan for you. Pet owners will also appreciate the Vital 200S, with its washable pre-filter and dual PM2.5 and VOC sensing.
Choose Winix if allergies, odors, or smoke are your main problem. The 5500-2 remains one of the best air purifiers for allergies in a medium room, and its washable carbon filter is genuinely better at cooking and pet smells than anything Levoit sells at the same price. If you are buying new today, the Winix 5510 is the direct successor, with the same filtration plus WiFi and a higher smoke CADR of about 253 CFM.
Choose Winix for large and open-plan rooms. The Winix 9800 is AHAM Verifide at 500 sq ft and is the better large-room buy in this comparison.
Choose Levoit for a small room or a first purifier. Nothing in Winix’s current lineup matches the Core 300’s combination of price, size, quiet operation, and verified CADR for a bedroom up to about 220 sq ft. The Levoit Core 300 review on this site breaks down exactly what it does well.
Our Top Picks
Match the purifier to your room: the Core 300 for bedrooms up to about 220 sq ft, the Core 400S or the 5500-2 for living rooms up to about 360 sq ft, and the 9800 for large spaces up to 500 sq ft. Amazon prices move often, and the discontinued 5500-2 is sold through remaining stock.
Frequently Asked Questions
Is Levoit or Winix better for allergies?
Both are strong, but Winix has a small edge. Its CADR figures are AHAM-verified across the lineup, and its deeper carbon filtration plus PlasmaWave handles the odors and VOCs that often come with allergy triggers. Levoit’s Vital 200S is the closest Levoit gets, with AHAM-verified CADR of 250 CFM for smoke and a dual PM2.5 and VOC sensor. For more allergy-focused picks, see our guide to the best air purifiers for allergies.
Is Levoit or Winix quieter?
Levoit is quieter at the low end. The Core 300 and Core 400S both reach 24 dB in sleep mode, while Winix models start around 26–28 dB. The difference is small — both are quiet enough for a bedroom — but light sleepers will notice it.
Does Winix PlasmaWave produce ozone?
PlasmaWave is a CARB-certified ionization technology, which means its ozone output is at or below 0.050 ppm, the safe level set by California standards. If you prefer zero ionization, you can switch PlasmaWave off and still get full HEPA and carbon filtration. Levoit models have no ionizer at all.
Is the Winix 5500-2 discontinued?
Yes. Winix America confirmed the 5500-2 was discontinued in the US and Canada in May 2025. It is still sold through remaining retailer stock, and Winix guarantees replacement filters through 2032. If you are buying new, the Winix 5510 is the direct successor, with the same True HEPA and PlasmaWave filtration plus WiFi and a higher smoke CADR of about 253 CFM.
Which brand has cheaper replacement filters?
Winix, over the long run. Its washable pre-filters and washable carbon filters mean you mostly replace only the HEPA filter, about once a year. Levoit’s 3-in-1 cartridges are replaced as a whole unit every 6 to 8 months, so you buy roughly twice as many filters.
Do Levoit and Winix air purifiers work with Alexa?
Levoit’s smart models — the Core 400S and Vital 200S — work with Alexa and Google Assistant through the VeSync app. Winix’s WiFi models, including the 5510, C545, and 9800, work with Alexa through the Winix Smart app. The Winix 5500-2 has no WiFi or app, so it cannot connect to a voice assistant.
Final Verdict
There is no single winner in Levoit vs Winix — there is a winner for your room. Levoit is the better buy if you want smart features, app control, and the quietest sleep mode. Winix is the better buy if you want independently verified cleaning power, stronger odor control, and lower filter costs, and the 9800 is the strongest large-room pick in this comparison.
Start with your room size. Under 220 sq ft, buy the Levoit Core 300. Between 300 and 400 sq ft, compare the Levoit Core 400S and the Winix 5500-2 or its successor the 5510 on price the day you shop — their cleaning power is nearly identical, so smart features vs. odor control is the real choice. Over 400 sq ft, buy the Winix 9800. Whichever you choose, size it by CADR and the AHAM room size, run it on auto, and replace the filters on schedule — that matters more than the logo on the front.
