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 of your Purifier. To clean the Blue Air purifier pre-filter, follow the steps shown in the above picture.

Clean the pre-filter regularly for optimal performance. Vacuum the exterior of the fabric pre-filter with a soft brush attachment to remove dust. If the pre-filter has to be cleaned more thoroughly, wash it in the washing machine on a gentle, low-temperature cycle.




Step 2: Power cycle your Blue Air Purifier

This issue can also happen when your air purifier gets too hot. Overheating is such a threat that it might affect not only the functionality of your air purifier but also cause irreparable damage.

Your air purifier can become overheated by several factors, including a faulty power source, malfunctioning internal components, and filter obstruction. But not all models meet these criteria. Most of them include a built-in safety feature that activates if your Purifier runs too long or gets too hot.

However, if the “clean filter” indicator is still flashing after resetting the device, check whether the machine is overheated or not. Let the device cool down for at least 60 minutes if it is. After then, turn on your and your problem should be solved!




Step 4: Replace the Filter

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.
