How large a room can the 600S handle?

Levoit rates it for rooms up to 635 sq ft, which suits a large living room or open-plan area. Smaller rooms will clean faster and run at lower fan speeds.

Does it produce ozone?

The plasma stage can generate trace amounts of ozone, which is why some owners turn it off in the app. HEPA and carbon filtration work without it.

Does it work with Alexa or Google Assistant?

The 600S has no built-in voice assistant support. You control it through the VeSync app, its display or a smart plug for basic on/off routines.

What filter does it use?

It uses a Levoit three-stage filter combining a pre-filter, HEPA and activated carbon, plus the plasma stage. Only Levoit-branded replacements are guaranteed to fit.

How loud is it at full speed?

The minimum is 26 dB, but high speed is much louder and noticeable in the same room. Auto mode keeps it near the quiet end most of the time.

Is it worth it over the Core 300?

The 600S covers far more square footage and adds app control, a display and a particle sensor. The Core 300 is smaller and simpler for a single bedroom.
