3. Replace the filter cover by lining up the cover’s feet with the slots on the bottom of the housing. [Figure 1.3]
4. Push the cover securely closed. [Figure 1.4] The air purifier uses a magnetic safety trigger to make sure that the filter cover is closed. If not properly closed, the air purifier will not turn on.

CARE & MAINTENANCE

Cleaning the Sensor Cover
If the air quality indicator does not seem to be accurate, clean the sensor cover.

1. Remove the sensor cover. [Figure 2.1]

2. Wipe the cover with a dry cloth. Wash the sponge with clean water, then dry it.
3. Replace the sponge in the sensor cover, and then replace the sensor cover.
   Note: Do not throw away the sponge. If the sponge is not in the sensor cover, the air quality sensor may not work correctly.

When Should I Replace the Filter?

Using your air purifier in an environment with relatively high pollution may mean you will need to change the filter more often, even if it is off.

You may need to replace your filter if you notice:

• Increased noise when the air purifier is on
• Decreased airflow
• Unusual odors
• A visibly clogged filter

Note:

• To maintain the performance of your air purifier, only use official Levoit filters. To buy replacement filters, visit Levoit’s online store. 
• Remember to reset after changing the filter.
