Tools & Requirements

Step-by-Step Solution

1

Secure Filters and Covers

The most common cause of rattling is a loose air filter or an improperly secured back/bottom cover. Turn off and unplug the purifier. Remove and reinsert the air filter, ensuring it"s seated firmly and correctly. Close all covers and panels, making sure they click securely into place. Test the unit again.

2

Inspect and Clean Fan Area

With the unit unplugged, carefully inspect the fan blades and the interior of the air intake/exhaust for any foreign objects like pet hair, dust bunnies, or small debris. Use a vacuum cleaner with a narrow attachment or compressed air to gently remove any obstructions. Never insert fingers or sharp objects into the fan.

Ensure Stable Placement

Place the air purifier on a hard, flat, and level surface. Soft or uneven surfaces like carpets can cause vibrations and rattling noises. Ensure all four feet of the unit are making firm contact with the ground.

Check for Loose Internal Parts

If the rattling persists, gently shake the unplugged unit to see if you can hear any loose parts moving inside. While not recommended for user disassembly, sometimes a component may have come loose during shipping or use. If you suspect an internal issue, contact Levoit customer support.
