When to Replace?

  • When the Filter button lights up red, it is a reminder to check and change the air filter.
  • We recommend replacing the air filter every 6-8 months for optimal use. It's time to replace the air filter when the following signals appear:
  1. Increased noise
  2. Decreased airflow
  3. Clogged filters

 

How to Replace the Filter?

  1. Unplug the power cord, rotate the top unit counterclockwise, and remove it upwards.
  2. Rotate the bottom cover as instructed and remove the old filter to open the new one.
  3. Place the top machine in the groove and screw it clockwise to complete the installation.
  4. Power the unit on. Press and hold the Filter Button for 3 seconds to reset the replacement reminder.

Note:

  • Only Compatible with Airthereal AGH400 Air Purifiers!
  • Package Content: 2-Pack AGH400 H13 HEPA Filter
