Why this filter
Before you buy
Confirmed for Core 400S-P only. Check the full model number, including -P; we have not confirmed older Core 400S models or filters sold for other countries. Pet, smoke and toxin versions need a separate compatibility check.
What’s included
The package contains one original three-layer replacement filter.
How this compares
This is a checked replacement, not a Best Overall or Best Value winner yet. Before choosing a winner, we need other filters we can trust, a fair comparison of how they work and how reliable they are, and current prices including shipping.
Filtration tests and details
These records explain which filter results we have checked and what their limits are. The same certification name does not mean two filters work equally well.
What we have verified about filtration
Manufacturer-supported fit does not by itself establish filtration efficiency, odor removal or superiority over another replacement. Those performance claims need their own reviewed evidence for the exact filter and equipment combination.

Installation and care
Installing the replacement
For Core 400S-P, Levoit’s linked US manual recommends replacement around 12 months, with earlier or later changes depending on use and pollution. The reminder means check the filter, not that its condition has been measured. Clean only the outer pre-filter every 2–4 weeks with a soft brush or vacuum hose; do not clean the main/carbon layers or use water. Before replacement, unplug the purifier. Remove all plastic wrapping from the new filter, fit it, close the cover and reset the filter reminder. Follow the manual if noise, low airflow, odors or visible clogging appear sooner.
Caring for the filters
Levoit says actual filter life depends on use and air conditions. Follow your purifier instructions and filter reminder; the subscription delivery choices are not a verified replacement schedule.
