Our air filters are effective for 1500 hours, or 6 months with a recommended daily usage of 8 hours.

Simply wipe or wash the pre-filter every week to maintain your HEPAS Air Purifier.

Also, you should not place an air purifier in the corner of a room; it should be placed at least 20cm away from the walls for maximum air flow.
