The reason why the air purifier keeps showing red and how to solve it!deep cycle battery price

　　What is the reason why the air purifier keeps showing red? It is well known that air purifiers have several indicator lights. First of all, we have to distinguish whether the air quality indicator light is on or the indicator light for filter cleaning is on. The indicator light’s position of every machine is different. But the indicator light on the machine will be marked.

　　The reason why the air purifier keeps showing red

　　1. Poor air quality

　　The indicator light keeps red, which means the current air quality is poor. The air quality detector at the air inlet of the portable air purifier will turn on a red light when it finds that the air quality is poor, indicating the user that the current air quality is relatively poor.

　　2. Too much dust on the filter

　　Another situation is that after using home air purifier for a long time, the internal filter has deposited a lot of dust. Generally, the system has the function of automatically prompting to replace the filter. If it is because the filter is too dusty, replace or clean the filter.

　　How to deal with these problems?

　　1. Air quality issues

　　If it is an air quality problem, this is normal. Just wait for the air purifier to purify the air in the room and it will slowly return to orange or green. If the red color still appears after a few days of use, check whether the air quality sensor is broken at this time, and you need to find after-sales service, just replace the sensor. If it is not broken or if it is repaired, it still shows red. At this time, it may be that you placed the air purifier in the wrong position. The air purifier cannot be placed close to the humidifier. If the humidifier is placed next to it, it is best to take it away. And It is best not to place the air purifier on the side of the wall. It should be kept at a distance of more than one meter.

　　2. Filter problem

　　If it is caused by too much dust in the filter, the first way is to press the reset button for 3 seconds. At this time, the red light will disappear and you can use it normally. The second is to cut off the power and clean or replace the air purifier. When it is installed, the system will automatically detect the purifier filter, and it will not turn red at this time.
