Levoit air purifiers are among the best in the market. They reduce allergens and protect against all kinds of smoke. However, maintenance of your Levoit air purifier ensures it works efficiently and for longer. One essential maintenance is replacing the HEPA filter in the device.
Levoit air filters have a ‘check filter’ indicator that illuminates as a reminder to check your filter when it needs replacing. After replacing the air filter in your Levoit air purifier, you must reset the air filter indicator light.

How does the Levoit filter light look like?
The Levoit check filter light is a blinking red symbol on the LED display. In some models, the symbol looks like a cylinder with two vertical lines in it. On others, it looks like two vertically oriented rectangles with horizontal lines. Regardless, the check filter indicator light will turn red.
What happens if you ignore the Levoit filter light?
No damage will happen to your air purifier if you change your filter but refuse to turn off the air filter warning. However, you will not know when it’s time for the next filter replacement. This is because the Levoit filter light is a maintenance feature that keeps you updated on your HEPA filter’s condition and alerts you when it’s time for a new filter.
If you don’t replace the filter and do not reset the indicator light, you should expect the following issues.
Reduced air purifier efficacy
The HEPA filter in your Levoit air purifier is an essential component as it does most of the heavy lifting when it comes to purifying the air. It traps airborne pollutants, including viruses, mold, and dust particles. Unfortunately, over time the filters clog with contaminants, reducing their effectiveness. The air purifier’s overall performance will drop significantly when you don’t replace the filter on time.
Increased health risks
If you do not change your filter, it will accumulate bacteria, mold, viruses, and other disease-causing particles. Therefore, your air purifier won’t be able to trap and clean harmful air-born particles. As a result, your air purifier will become a new breeding ground for mold and bacteria, leading to an increased risk of respiratory issues, allergic attacks, and more.
Increased electricity costs
Running your air purifier with a clogged filter will increase energy consumption and costs. In addition, the fans will work harder to push air through the clogged filter, putting additional strain on the motor and increasing electricity usage.
Increased odors
The Levoit air purifiers are also efficient at minimizing odors in your home. So allowing the filter to clog will increase the foul odor in your space. In addition, if the air filter is clogged, it will no longer trap and neutralize the odor-causing particles in the air.
How often does the Levoit air filter light come on?
Ideally, the Levoit filter light will come on every six months to ensure the unit works efficiently at eliminating particles, bacteria, odors, mold spore, allergens, etc. However, the Levoit air indicator light comes on for a number of reasons.
It doesn’t always mean you should change the filter. The check filter light is a reminder to confirm your filter is in good condition and an opportunity to clean the pre-filter.
But if you notice the following, you need to replace the Levoit filter:
- The air purifier is running louder than usual.
- The airflow is not as strong as usual.
- The room with the air purifier has a foul odor.
Additionally, it’s worth noting the frequency of changing your Levoit air filter depends on the model, air pollution level, and how often and speed you use your air purifier.
Fourteen Levoit air purifier models require a filter change every 6-8 months. In comparison, the other two models(PlasmaPro™ 400S Smart True HEPA Air Purifier and VeSync Core 400S Smart True HEPA Air Purifier) may not need a new filter for up to 12 months.
Also, if you live in a highly polluted area or run your air purifier often, you may have to change the filter more frequently.
Can the Levoit air filter light be a false alarm?
If you did everything right, the filter light should turn off. But sometimes, system errors can prevent the indicator light from resetting. Try rebooting the air purifier －switch off and unplug it for about 30 minutes, then replug it. So if nothing gets rid of the red light on your Levoit purifier, the reset button could be lagging, and you will need to contact Levoit customer service as it may indicate a deeper issue.
Conclusion
Levoit air purifiers are among the best at cleaning home air. And since they are filter-based, their efficiency relies highly on their filters. That’s why they have a check filter indicator light that alerts you it’s time to check your filter.
If your filter is clogged, replace it and then reset the filter light. If not, turn off the filter light by resetting it. We hope this article teaches everything you need to know to reset the filter light on your Levoit air purifier.
