Levoit Core 400S Smart Air Purifier review
A large living room or open-plan space, bought direct from Levoit
By Tom Calder · Updated 24 July 2026 · Price checked against our tracker
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.
Price confirmed directly on Levoit's official UK store as of Jul 2026 — a clean matching Amazon.co.uk listing couldn't be confirmed this round, so buy direct from Levoit or search carefully before trusting a marketplace listing.

- 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
