Our Verdict
Winix 5500-2
Winix C545
The Winix 5500-2 is better than the Winix C545. Both models have air quality sensors that allow them to automatically adjust their fan speed depending on real-time particle levels. That said, the 5500-2 has a higher clean air delivery rate and better fine particle filtration performance, all while occupying a similar footprint. Meanwhile, only the C545 is Wi-Fi enabled, which allows you to remotely operate it from afar.
