Why the filter light on a Levoit air purifier needs to be reset
The check filter light on your Levoit air purifier is an automated feature that turns on, in color red, at intervals. It needs to be reset so that it can refresh the monitoring session on your air filter and alert you at the end of the next interval.
Other reasons why you would need to reset your Levoit air purifier include:
- You replaced the old filter
- You’ve been running your purifier in a heavily polluted area and your purifier is not filtering out particles from the air as expected. This would require a filter replacement and then resetting of your unit.
- All lights – air quality indicator and check filter indicator- are turned on in the LED display section.
- The display is not working as expected.
- Your unit is beeping incessantly.
- If after replacing a filter, the light did not come on automatically.
How a Levoit Air Purifier Works
The Levoit air purifier uses three filtration stages to remove different types of air pollutants and provide fresh air to you.
The first stage is a pre-filter often made of nylon. It captures large particles like dust, lint, fibers, hair, and pet fur. This stage maximizes the life of the True HEPA filter.
The second stage contains a True HEPA filter which removes over 99% of tiny air particles of micron sizes. It takes care of air particles like mold spores, dust particles, smoke, mites, and allergens.
The third filtration stage contains a high efficiency activated carbon filter which absorbs smoke, odors and fumes from the atmosphere. Chemical compounds like formaldehyde, volatile organic compounds, benzene, ammonia, and hydrogen sulfide are all removed in this final stage.
The Levoit air purifier: light colors, and their meaning
Your Levoit air purifier takes five to thirty seconds to detect air quality each time it is turned on. Every model of the Levoit air purifier has air quality indicator rings on the LED display feature.
It uses an automatic sensor to display the air quality, the sensor uses infrared light to detect airborne particles. The default color at the first switch is blue, and after a few seconds, the color on the rings changes based on the detected air quality.
The auto mode of your Levoit air purifier allows your fan speed to adjust automatically based on quality. The lower the quality of air detected, the higher the fan speed. Other colors that may be displayed are red, green, or yellow/orange.
A Red light indicates that the air quality is bad and that the fan speed will be high to efficiently clean the air.
A Yellow or orange color means that air quality is moderate and the fan speed will be on medium.
A Green light means good air quality and the fan speed will be set on low.
A Blue light means very good air quality and the fan will be in sleep mode since there’s no contaminant to remove.
Why the red light on a Levoit air purifier is blinking
A blinking red light on your Levoit air purifier simply means to check your filter life. You can turn this off by resetting the system.
Why the Levoit air purifier red light won’t turn off
If the air quality indicator on your Levoit air purifier is stuck on red, then it is possible that dust has accumulated in the sensor of your unit. You can clean the dust sensor in the device with these steps:
- Turn off and unplug the purifier.
- Open the cover on the dust sensor – check your user manual to locate the dust sensor.
- Use a cotton swab dipped in clean water to clean the lens of the sensor.
- Dry the sensor with a clean, dry cotton swab.
- Close the sensor.
If the red light is on your check filter indicator, you can either change the filter and then reset the device. Or reset it without changing the filter.
You can also try unplugging your unit and leaving it to rest for about half an hour. Then replug and see if the filter red light is gone.
If this problem persists after you have tried all these options, you’ll have to reach out to the Levoit customer support using any of the options (call or mail) on the help button at the top right of the website.
