Levoit Core 300 Replacement Filter Evidence Guide
This guide separates official compatibility evidence from marketplace seller claims, part-number ambiguity, and unresolved misfit risks.
Current answer
Evidence-based compatibility answer
Current evidence supports confirmed Levoit Core 300 compatibility records including Core 300-P-RF, Core 300-P-RF-PA, Core 300-P-RF-TX, and other confirmed records. Marketplace listings remain signals, not official compatibility proof. The current evidence set still preserves unresolved or higher-risk part-number, model-family, or seller-claim boundaries where the evidence does not prove equivalence.
Evidence basis
Confirmed compatibility records, official evidence records, marketplace signal summaries, and the top-level evidence rating snapshot for this guide page.
Boundary
Seller claims, broad listing titles, and marketplace text do not create confirmed compatibility.
Next evidence to look for
Check official Levoit filter-code, model-variant, and replacement-interval evidence.

Low risk
Risk boundary
- Keep Core 300, Core 300-P, Core 300S, and Core P350 model language separated unless the evidence supports grouping.
- Do not assign a part code to a filter variant unless the official source exposes that code.
- Marketplace pack-count, media, or low-price claims do not prove official compatibility.
Confirmed compatibility from official evidence
This table lists compatibility relationships supported by official evidence. Rows with missing part numbers are shown as evidence gaps, not complete replacement-part records. The compatible part/filter label uses the best available part record label when an official SKU is not captured.
This table is filtered to the scope of this page.
| Device | Compatible part / filter | Official part number / SKU | Status | Evidence source | Scope / region | Risk | Last checked | Confidence |
|---|---|---|---|---|---|---|---|---|
| Core 300 | Original Filter | Core 300-P-RF | Confirmed | Other | Region not specified | Medium risk | 2026-05-26 | 90 |
| Core 300 | Original Filter | Core 300-P-RF-PA | Confirmed | Other | Region not specified | Medium risk | 2026-05-26 | 88 |
| Core 300 | Original Filter | Core 300-P-RF-TX | Confirmed | Other | Region not specified | Medium risk | 2026-05-26 | 88 |
Official evidence gaps
Some official evidence records confirm model-level compatibility but do not expose a visible part number in the captured data. Treat these as evidence gaps, not complete replacement-part records.
| Device | Compatible part / filter | Official part number / SKU | Status | Evidence source | Scope / region | Risk | Last checked | Confidence |
|---|---|---|---|---|---|---|---|---|
| Core 300 | Original Filter | Part number not captured | Confirmed | Other | Region not specified | Medium risk | 2026-05-26 | 82 |
