Air filter cartridge Levoit Core 300 / 300S HEPA replacement filter

Replacement HEPA air filter designed for use with Levoit Core 300 and Core 300S air purifiers. This cartridge restores the purifier's particle-capture capability by using a HEPA-class filtration layer that traps dust, pollen, pet dander and other fine airborne particles to help maintain indoor air quality in homes and offices. The filter is intended for periodic replacement to sustain efficient performance and reduce recirculation of captured contaminants.

Advantages

The filter offers HEPA-class particle capture that improves removal of airborne particulates and common allergens. It is shaped to fit Levoit Core 300 and Core 300S models for straightforward installation and secure positioning inside the purifier. The cartridge is a single integrated unit that simplifies replacement and maintenance compared with multi-component filters. Using a fresh filter helps preserve fan efficiency and consistent airflow by preventing clogging from accumulated particles.

How to use

Turn off and unplug the air purifier before replacing the filter.

Close the cover, plug in the purifier and reset the filter indicator if the model includes a reset function. Follow the purifier manufacturer's maintenance schedule to determine replacement intervals based on operating hours and local air quality.

Usage recommendations

Replace the filter at regular intervals recommended by the air purifier manufacturer or sooner when used in environments with heavy dust, pet hair or high pollution. Store unused filters in a dry, clean location and avoid compressing the cartridge. For optimal performance combine timely filter replacement with routine cleaning of pre-filters and unobstructed airflow around the purifier.
