You might be a new user of the Blue Air purifier or you may have done what you were supposed to do when the red light flashes, but it didn’t work,
Right?
Well, the red light on a Blue Air purifier flashes when the HEPA filter is blocked and needs to be cleaned.
Sometimes, the red light may continue to flash even after the filter has been cleaned.
The solution is pretty simple and takes only 2-3 minutes to perform.
Here we go! Let’s dive into it…
What does Red light mean on Blue Air purifiers?
Typically, the Red light on a Blue Air purifier flashes when the filter is clogged with debris or damaged completely. Aside from these, overheating or internal systems glitches also sometimes trigger this issue.
Look at this table:
| Reasons for red light issue | Solutions |
|---|---|
| Filter needs to be replaced | Replace the filter with a new one. Check the bottom of this article for instructions on how to replace the filter. |
| Air purifier is not getting enough airflow | Check if the air intake and outlet vents are blocked by any objects. Remove any blockages and ensure that there is enough space around the air purifier for proper airflow. |
| Sensor malfunction | If the red light continues to appear after checking the filter and ensuring proper airflow, there may be a sensor malfunction. Contact the manufacturer or a professional technician for assistance. |
How to Fix Blue Air Purifier Red Light Issue?
First, check the filter. If the filter is dirty or broken, clean or replace it. But if the red light still won’t turn off after cleaning or replacing the filter, press and hold the main button (in some cases labeled “filter”) for 10 seconds. After that, your problem should be fixed!
Here are the detailed step-by-step guidelines;
Step 1: Clean the Pre-filter
According to the Times of India, a clogged or damaged filter might cause an air purifier to stop functioning or to start behaving incorrectly.
Although there are other potential causes for why it can stop working, a damaged or clogged filter is the big culprit.
So, before you do anything else, try cleaning the pre-filter. To clean the Blue Air purifier pre-filter, follow the steps shown in the above picture.
Step 2: Power cycle your Blue Air Purifier
You have just cleaned the filter or even replaced the old one with a new one, but your Blue Air purifier still displays the red light! What could be the issue?
OK relax! First of all, you don’t need to worry about it. It’s just a software glitch in your device and can be easily fixed through a reset.
Here’s how to do that:
- Turn on the device.
- You will see the filter indicator shining red. Don’t worry!
- Now press and hold the main (in some cases “filter”) button for about 10 seconds.
After 10 seconds, the red light will stop shining and turn white. Now continue using your device.

Step 3: Let the device cool down
The red light may also flash when the purifier gets too hot. Overheating is a serious threat that can not only affect the functionality of your air purifier but also cause irreparable damage.
Several factors, including a faulty power source, malfunctioning internal components, and filter obstruction, can lead to overheating.
However, not all models meet these criteria. Most of them include a built-in safety feature that activates if the purifier runs for too long or gets too hot.
If the “clean filter” indicator is still flashing after resetting the device, check whether the device is overheated or not. If it is, let the device cool down for at least 60 minutes. After that, turn on the device and your problem should be solved!
Step 4: Replace the Filter
When was the last time you changed the filter on your Blue Air purifier? Did you change the filter within the last six months? I am sure you haven’t changed its filter in the last six months.
But did you know that Blue suggests that users should change the filter every 5-6 months?
According to Blueair, you should be serious about the filter and must replace the filter at least two times a year to get optimal functionality.
So as a last option, try replacing the filter with a new one. Follow the below video guide to replace your Blue air Purifier filter.
Use only genuine Blue air filters compatible with your model to ensure optimal performance and efficiency.

Q: My Blue Air purifier is flashing red light, but I recently replaced the filter. What should I do?
If you have recently replaced the filter and the red light persists, there may be another issue with the purifier.
Check if the filter is correctly installed, ensuring it fits securely in place.
If the problem continues, reach out to Blue Air’s customer support for further assistance and troubleshooting guidance.
Q. How often should I clean my Blue Air purifier filter?
If you have pets or live in a dusty area, you may need to clean your Blue air purifier filter more often than the recommended one every two to four weeks.
However, if neither of these applies to you, the general rule is to clean your filter every two months.
