Important:
To ensure optimal filtration efficiency and maintain your warranty coverage, always use OEM Aliencell filters.
Using third-party filters may result in equipment damage, poor filtration, or inaccurate sensor readings.
¶ 1. Monitoring Filter Life
You can check the remaining filter lifespan using the two methods below.
¶ Method A: Check the Purifier Screen
The purifier's built-in display shows the real-time remaining life percentage for all 5 filter layers.
-
① - ⑤ Filter Levels: Corresponds to filter layers 1 through 5.
-
Percentage: Indicates remaining lifespan (e.g., 99% indicates new, 0% indicates replacement is required).
Indicator Icon Light Status Device Status Filter Status 
Solid On Normal (Displays remaining life, e.g., 98%) 
Blinking Replacement Required (Life reached 0%) 
Blinking No Filter Detected (Check installation)
¶ Method B: Access filter life via connected Aliencell X1 touchscreen
When the purifier is connected to the Aliencell X1, you can view detailed data directly on the machine's touchscreen.
- Tap the Accessory Info icon in the bottom right corner of the screen and select Air Purifier to view the specific lifespan of each layer.
When filter life approaches or reaches 0%, please contact your local dealer or visit the official Aliencell online store to order replacements.
