Both records are reviewed against the manufacturers' sources; sources last checked 2026-10-14. Informational only: confirm with the manufacturer before buying.
Why
- ✓ Both use Levoit Core 400S filter.
Good to know
- Not interchangeable with Core 300 or Core 600S filters.
- Levoit now sells most models with a "-P" suffix (e.g. Core 300S-P). Levoit's parent VeSync lists the original and -P versions as sharing this filter; levoit.com's own filter pages often name only the -P model.
- Levoit says its filter-life indicator and algorithm only work with authentic Levoit filters.
