Air purifiers are important devices that help improve indoor air quality. However, many users encounter a situation where the air purifier shows a red light, causing anxiety and inconvenience. This article will help you understand the causes and how to fix this situation.
1. Reasons why the air purifier shows a red light
1.1. Polluted environment causes the air purifier to show a red light
The air purifier is placed in an environment with a lot of dust or toxic substances, then the AQI index will fluctuate between 150 and 250, with a red warning light. To warn users, the room’s current air quality is at a dangerous level and needs to be cleaned immediately.
1.2. Do not replace and clean the filter periodically
Not replacing the filter as recommended by the manufacturer or not cleaning it periodically is also the main reason why the machine reports a red light. A clogged filter will reduce air filtration efficiency and cause a warning. Many users often forget to schedule filter replacements, leading to poor air quality.

1.3. Faulty sensors and other parts
A sensor contaminated with dust or steam, or other parts such as a damaged exhaust fan, can also cause the air purifier to display a red light. This is also a reason that users often encounter when using the device. If the sensor does not work correctly, the machine will not be able to properly measure air quality and automatically give a red alarm even though the air in the room may still be clean.
2. Harmful effects of red air purifiers
When the air purifier shows a red light, the air filtration efficiency will decrease and the indoor air will not be cleaned properly. This can affect the health of you and your family, especially those with weak respiratory systems or chronic diseases such as asthma or allergies.
Symptoms can include difficulty breathing, dry cough, itchy eyes, and even more serious problems if the condition persists. In addition, this condition often lasts for a long time and also causes anxiety and inconvenience while using the device for users.
3. How to fix air purifier red light error
3.1. The air purifier shows a red light when the environment is polluted
If the cause is due to air pollution, then you don’t need to worry too much. Install the machine or set it to automatic mode so that the air purifier will start working and clean the air for you.
After a period of stable operation, the air quality index will decrease and the light will gradually change from red to orange to green. When the air quality in your room has been cleaned, you can completely rest assured about the air quality at this time.
3.2. Check and clean the filter
If your air purifier has been running for a long time and the light still lights up red. Now check the air purifier filter. If the filters are dirty, clean them or replace them if it is time to change the filters.

3.3. Check the air quality sensor
Checking the air quality sensor is also a way for you to fix the red light of the air purifier. Clean the sensor so that dirt or moisture does not stick to it, ensuring the sensor operates normally. If the sensor is broken, contact the manufacturer to replace the sensor with a new one.
3.4. Contact the manufacturer or service center
If the above measures do not solve the problem, you should contact the manufacturer or a warranty center for advice and technical support. They can help you identify deeper problems you might not see, such as software errors or hardware damage.
4. Be careful when using the air purifier to avoid encountering a red light
Do not use the air purifier continuously: Let the machine rest after a period of operation to avoid overload. When using, make sure the room is always closed and limit opening the door when the machine is operating. This will help the air purifier work more effectively, minimizing red alerts
Regularly clean and replace filters: Monitor the filter replacement and cleaning schedule regularly to ensure optimal machine performance. You should note the replacement time in your calendar or use a reminder app so you don’t forget
Avoid placing the machine near cooking areas or explosive substances: Placing the air purifier in an appropriate location will help limit dust and toxic gases that affect the machine’s performance. Choose a well-ventilated and easily accessible place for cleaning
The air purifier shows a red light is a common condition but can be easily remedied if you understand the cause and take the right measures. Please maintain the machine regularly to ensure the efficiency and longevity of the device, helping you and your family always have a clean and safe living environment.
