Levoit Core 300S review
The cheapest way to get an app and auto mode, for one bedroom.

Budget bedroom
4.0/ 5$149
Good for
- One bedroom up to 18 m²
- App and auto mode on a budget
- Low filter costs
Not for
- Living rooms
- Heavy smoke in anything but a small room
Verdict
A lab-tested 145 m³/h is enough for a single bedroom, and you get the same app, scheduling and quiet sleep mode as the bigger 400S. Filters are cheap at about $65 a year.
It's a small unit and behaves like one. For anything bigger, get the 400S.

How it handles Perth's air
- Bushfire smoke: fair. Fine for a small bedroom with the door shut.
- Pollen: good in a bedroom.
- Dust: good.
- Pets: good.
Watch out
Like the 400S, Levoit no longer states a HEPA grade. Past about 18 m² it struggles.
Alternatives
- Coway Airmega 150: a stated H13 filter and no app.
- Levoit Core 400S: more than double the clean-air rate for $100 more.
- See the best purifiers for bedrooms.
