Other filters Levoit sells for the Core 300S-P
Besides the standard filter, Levoit lists this for the Core 300S-P. The type is Levoit's own description of what the filter is for; we have not tested any of them, and the purifier's published CADR is for its standard filter.
| Type | Filter | Price | vs. standard | Why it's listed for this purifier | |
|---|---|---|---|---|---|
| Smoke | Levoit Core 300-P 4-Stage Smoke Remover Replacement Filter | $39.99 checked 2026-10-11 | +$10 | Levoit's listing names it: “Compatible with only: Core 300-P, Core 300S-P, Core P350-P” (source, confirmed 2026-10-11) |
Prices are from Levoit's store. The yearly cost above uses the standard filter; a dearer filter replaced on the same schedule raises it in proportion. A pre-filter is the outer layer that catches hair and large dust before the main filter.
When to replace it
- Follow the purifier's filter indicator rather than the calendar: it tracks actual use, and the brand's schedule is a maximum under normal conditions.
- Wildfire smoke, heavy cooking, pets and dusty rooms shorten a filter's life. A filter that looks grey or carries a smell is due even if the light hasn't come on.
- Third-party filters are cheaper, but the brand's performance figures only apply with its own filter, and on some purifiers the filter-life tracking only works with genuine ones.
