**Replace your HEPA filter immediately and perform a filter reset to stop your air purifier’s red light from blinking.**
* **Filter Replacement is Paramount:** The blinking red light is almost universally an indicator that your HEPA filter (and often the pre-filter/carbon filter, if combined) has reached the end of its lifespan and needs to be replaced. These lights are timed reminders.
* **Manual Filter Reset is Critical:** After installing a new filter, you *must* manually reset the filter indicator. This typically involves pressing and holding a dedicated “Reset,” “Filter,” or “Timer” button for 3-5 seconds until the light changes color (e.g., green) or turns off. Refer to your specific purifier’s manual for exact instructions.
* **Verify Proper Filter Seating:** Ensure the new filter(s) are correctly oriented and firmly seated within their compartment. A loose or improperly installed filter might prevent the system from registering the new filter or completing the reset.
* **Power Cycle the Unit:** If the light persists after replacement and reset, unplug the air purifier from the wall outlet for 60 seconds. Plug it back in and attempt the filter reset procedure again.
* **Consult Your Manual:** While filter replacement and reset are the primary fixes, your specific model’s manual may offer unique troubleshooting steps for the blinking red light.
* **Consider a Sensor Malfunction (Rare):** If, after replacing the filter, correctly resetting the indicator multiple times, and power cycling, the red light still blinks, there *could* be an issue with the internal filter sensor. In such a rare case, contact the manufacturer’s customer support.
