No, each model uses its own 3-stage H13 True HEPA cartridge sized for its body, though both follow the same design and are rated at roughly 8 months. In both cases the pre-filter layer is part of the sealed cartridge and is vacuumed or brushed rather than washed.

No. Both use a laser PM2.5 sensor that drives auto mode and an LED display, and owners describe it reacting to cooking within seconds. Neither Levoit Core 400S-P nor Levoit Core 600S-P detects VOCs, CO2 or formaldehyde, so odors are handled by the carbon layer with no reading to show.
