Levoit Core 400S Smart Air Purifier review
A large living room or open-plan space, bought direct from Levoit
By Tom Calder · Price last checked 20 Sep 2026, 12:29 BST · price-tracked
Levoit's biggest single-room coverage figure on this list at 166 m², with a clearly stated 6–8 month filter-replacement schedule. The catch is Levoit hasn't published CADR or noise figures for this model, so you're comparing room size alone against rivals that publish the fuller picture.

- Largest stated room coverage on this list (166 m² once-hourly)
- Clear, published filter-replacement schedule (6–8 months)
- 3-stage HEPA plus carbon filtration traps particles to 0.3 microns
- No published CADR figure, so it can't be directly compared on airflow to rivals like the Xiaomi or Winix
- No published noise rating, so you can't judge bedroom suitability against other models
- No single confirmed Amazon.co.uk listing at time of writing — buying direct from Levoit is the safer route
Who shouldn't buy this
you want to compare purifiers strictly on CADR before buying — Levoit doesn't publish one for this model.
