Our take
A purifier is only as good as its filter, and a clogged one moves far less air. Levoit's own Core 300-RF restores the Core 300 or 300S to its rated performance: the pre-filter catches hair and lint, the H13 HEPA layer catches fine particles, and the carbon takes the edge off smells.
Cheaper copies sell under the same part number, but Levoit's rated figures are for its own filter.

Good for

- Keeping the purifier at its rated clean air
Skip it if
- You have a Core 400S, 600S or Vital: each takes its own filter

Questions about the Core 300-RF Original Filter
- How often should I replace the Levoit Core 300 filter?
- Levoit says every 6 to 8 months. In heavy smog or smoke it fills faster: if the filter looks grey and the air feels stale, change it.
- Does the Core 300-RF fit the Core 300S?
- Yes. The Core 300, Core 300S and their -P versions all take the Core 300-RF.
How we judge. We haven't tested the Core 300-RF Original Filter in a lab of our own. The figures come from independent ratings (AHAM, Energy Star, NIOSH, the ASPCA) or the maker, and the verdict is ours, from those figures. No brand pays to be listed. Last checked Nov 7, 2026.
