Levoit Vital 200S vs Winix 5500-2
Bottom line
In our scoring the Levoit Vital 200S wins at 7.1/10 (Mixed) to the Winix 5500-2's 6.2/10 (Limited). The 0.9-point gap comes from two places: safety, where the Levoit's lack of an ionizer scores 8.0/10 against 5.0/10 for the Winix's switchable PlasmaWave (which CARB does list), and total cost of ownership (6.0/10 against 4.5/10). The Levoit is also quieter on its own published figures, 23 dBA against 28, and marginally cheaper to feed. The Winix has real strengths: it is about $10 less up front, its washable carbon pre-filter holds down running cost, and its AHAM-verified CADR nearly matches. In our view the Levoit is the better buy unless you will reliably run the Winix with PlasmaWave switched off.
These two land in the same place for most shoppers, a medium room at around $160 to $170, so the deciding question is what each does to the air on the way out. The Levoit Vital 200S uses no ionizer and no ozone-producing stage at all, and it appears on California's CARB list of certified air-cleaning devices. The Winix 5500-2 includes PlasmaWave, an ionizer you can switch off, and it also appears on the CARB list (model 5500-2, Executive Order G-16-053), so its safety dimension earns partial credit at 5.0/10 in our scoring against the Levoit's 8.0/10. On airflow they are close and both are AHAM-verified: 289 cfm at the Levoit's highest verified figure against 246 for the Winix, with room ratings on both sides (380 sq ft and 360 sq ft) that sit inside what each unit's own CADR supports. Filters run about $50 a year for the Levoit and $59 for the Winix.

FAQ
- Is the Levoit Vital 200S better than the Winix 5500-2?
- In our scoring the Levoit Vital 200S rates 7.1/10 and the Winix 5500-2 6.2/10. In our scoring the Levoit Vital 200S wins at 7.1/10 (Mixed) to the Winix 5500-2's 6.2/10 (Limited). The 0.9-point gap comes from two places: safety, where the Levoit's lack of an ionizer scores 8.0/10 against 5.0/10 for the Winix's switchable PlasmaWave (which CARB does list), and total cost of ownership (6.0/10 against 4.5/10). The Levoit is also quieter on its own published figures, 23 dBA against 28, and marginally cheaper to feed. The Winix has real strengths: it is about $10 less up front, its washable carbon pre-filter holds down running cost, and its AHAM-verified CADR nearly matches. In our view the Levoit is the better buy unless you will reliably run the Winix with PlasmaWave switched off.
- Is PlasmaWave a problem?
- We do not make that claim. PlasmaWave is an ionizer you can switch off, and ionizers can produce ozone as a byproduct, so we only credit one when its CARB ozone-compliance listing is verified. This unit is on the CARB list (model 5500-2, Executive Order G-16-053), which is why its safety dimension scores 5.0/10 here against 8.0/10 for the Levoit, which has no ionizer. That is a statement about what we could verify, not a measurement of its emissions. Run it with PlasmaWave off and it works as a plain HEPA filter.
- Which covers a bigger room?
- The Levoit, slightly. It is rated for 380 sq ft against the Winix's 360, and both claims sit inside what each unit's own AHAM-verified CADR supports at 4.8 air changes per hour, which is the test that matters more than the number itself.
- Which costs less over five years?
- The Levoit, narrowly. We compute about $420 over five years including the device against roughly $457 for the Winix. The Winix is about $10 cheaper up front, but its filter runs about $59 a year to the Levoit's $50, so the gap closes and then reverses.
