Overview
Not a complete purifier, this is a single replacement filter built for the Levoit Core 400S-P. It combines an H13 HEPA layer with high-efficiency activated carbon to trap particles, smoke and odors.
Replacing the filter restores the purifier's cleaning performance once the old one clogs, and the genuine part matches the housing. Other Levoit filter types exist for specific jobs, so this one is the standard option.
Who it's for
Owners of the Core 400S-P who want a like-for-like standard replacement are the match. Buyers with a different model should check fit, and those with smoke or pet concerns may want a different filter type.
Pros and cons
- Genuine part for the named model
- H13 HEPA layer
- Activated carbon for odors
- Single filter, simple swap
- Fits one purifier line only
- Specialty filters sold separately
- Replacement interval not listed
Performance notes
Air passes through the HEPA layer, which traps fine particles, then through the activated carbon, which adsorbs odors and gases. As the media loads, airflow drops and capture efficiency falls, which is why replacement is needed. Using the matching genuine filter helps the seal fit tightly in the housing.
