How to replace levoit core 300 filter

To replace the filter on a Levoit Core 300 air purifier, follow these steps:

Turn off and unplug the air purifier

Safety is the top priority when working with electrical appliances. Ensure the air purifier is powered off and unplugged from the outlet before proceeding.

Remove the filter cover

Flip the unit upside down to access the filter compartment. Locate the bottom cover, which is secured by a twist-lock mechanism. Rotate the cover counterclockwise to unlock it. Once loose, lift the cover off to expose the levoit core 300 replacement filter inside.

Take out the old filter

The Levoit Core 300 uses a cylindrical filter that sits snugly inside the purifier. Simply pull the old filter out of the compartment. If the filter looks discolored, dusty, or clogged, it's definitely time for a replacement.

Clean the inside of the unit (optional)

Before inserting the new filter, it’s a good idea to clean out any dust or debris inside the air purifier. Use a dry, soft cloth or a vacuum with a soft brush attachment to gently clean around the filter compartment. Avoid using water or any liquids, as they could damage the device.

Unpack and install the new filter

Open the new filter packaging, being careful not to damage the delicate pleats or materials. Insert the new filter into the air purifier, making sure it fits snugly and securely in place. The Levoit Core 300 filters are designed to be installed with ease, so you won’t need to apply much force.

Reattach the filter cover

Once the new filter is in place, reattach the cover by aligning it with the slots and turning it clockwise until it locks securely. Ensure the cover is firmly in place to prevent air leakage, which could reduce the purifier’s efficiency.

Reset the filter indicator

After replacing the filter, the filter indicator on the Levoit Core 300 will likely be illuminated. To reset it, turn on the air purifier, press and hold the "filter reset" button for about 3 seconds. The light should turn off, indicating that the reset was successful.

Regular maintenance

Levoit recommends changing the filter every 6-8 months, depending on your usage and the air quality in your environment. Monitor the filter indicator light and the filter’s appearance for signs of wear, but changing it within this time frame ensures optimal air purification.
