Levoit Core 600S-P, at an AHAM Verifide 391 CFM smoke CADR for 606 sq ft, against 253 CFM for 392 sq ft on Winix 5520. Both figures are certified, so this is a genuine difference in air movement rather than a marketing comparison.

Winix 5520 uses a washable fine mesh pre-filter, an activated carbon layer, True HEPA and an optional PlasmaWave ionizer. Levoit Core 600S-P uses a sealed 3-stage H13 True HEPA cartridge rated at about 8 months, with no ionizer and an ozone-free certification, whose pre-filter layer is vacuumed rather than washed.

Levoit Core 600S-P, which works with Alexa, Google Home and Home Assistant through the VeSync integration and ships with a physical remote. Winix 5520 documents Alexa support through the Winix Smart app, with Google Home unconfirmed. Neither supports HomeKit or Matter.

Winix 5520 quotes 27 dB at its lowest speed and adds a light sensor that switches it to sleep mode when the lights go off. Levoit Core 600S-P has a sleep mode with a dimmed display, but it is a bigger fan sized for a larger room, so it works harder in the same space.

Anyone treating an open floor plan, a high-ceilinged room or several connected spaces with one purifier, and anyone who wants an ozone-free design, child lock and Home Assistant control. For a normal living room at a lower price, Winix 5520 remains the value pick.
