Levoit Vital 200S vs Winix 5500-2

The Winix 5500-2 and Levoit Vital 200S are evenly-matched air purifiers. Both appliances deliver near-equal particle filtration performance and a sufficiently high clean air delivery rate for larger spaces. That said, there are a few differences. Only the Levoit is Wi-Fi enabled, allowing you to pair the device with your smartphone, allowing for full remote operation and live monitoring of current air quality. Conversely, unlike the Levoit, the Winix has an ionizer, which produces negatively charged ions that ultimately cause small particles to be attracted to one another and form large, easily-cleaned clumps. That said, ionizers produce ozone, a potential respiratory irritant as a byproduct - while Winix claims their iteration of this technology doesn't produce harmful levels of ozone, you can always turn it off anyway.
