Levoit Core 600S-P uses a sealed 3-stage H13 True HEPA cartridge rated at roughly 8 months, whose pre-filter layer is vacuumed rather than washed, so the whole cartridge is replaced together.

Levoit Core 600S-P, which adds Home Assistant through the VeSync integration on top of Alexa and Google Home, and ships with a physical remote for people who do not want to reach for a phone.

Buyers with the largest rooms, or anyone who wants to watch PM1, PM2.5 and PM10 move independently during cooking or a smoke event. It also has the lower power draw and a washable pre-filter, at the cost of a 1 year warranty where Levoit Core 600S-P offers 2 years.
