A lot of customers that used genuine replacement filters had a lot of trouble turning on the air purifier. There are also some users whose air purifiers didn’t work after replacing the old air filter with a new filter.

Touch Screen Not Working Levoit Air purifier

In all of these cases, the safety latch is the main problem that is the root cause of these issues.

  • With their recent models, Levoit introduced a safety latch at the bottom side.
  • It is present where the filter cover joins the main body.
  • There is a small tab that goes into this latch and the air purifier knows that the filter cover door is closed.
  • When the safety latch doesn’t meet with the tab and the filter cover remains opened, then the issue arises with the air purifier and it becomes unresponsive.

It is a really important feature as it stops the fans from spinning while the door is open.

The Easy Fix

You should try the following method:

  1. Unplug the unit and open the filter
  2. Locate the safety tab and make sure it isn’t damaged.
  3. Locate the latch and make sure, there is nothing stuck in it.
  4. Close the door carefully while making sure the tab goes securely into the latch.
  5. Plug the purifier back on.

If you’re lucky, these steps should fix your air purifier. Check filter light again and it should be off now. Even if you have tried all of the steps and even replaced the old filter, but still nothing is working then the latch or the purifier is the main culprit. In such as case you should contact Levoit customer service.

Quick Solution

One simple fix is to turn it to the maximum setting to clear the air. If this solution doesn’t work then you can try some other things.

Removing Diffuser or Humidifier

Make sure there is no diffuser or humidifier present near the air purifier. These devices release large particles into the air and the air purifier might be tricked into thinking that the air is not clean.

Choose a Location Away From the Vent:

Another thing is to keep the air purifier away from the vent.

  • If it is present close to a vent then the purifier might misread the air quality of the room. Therefore, you should look for any vents blowing air into the air purifier.
  • Move the air purifier to a different location, probably in a different room. This will tell you whether the room is too humid or the device is faulty.
  • If there is a problem with the air purifier then you can manually reset it by pressing and holding it for 20 secs. This should update the settings the air quality light should turn off.


In the case of a warranty for the air purifier, you can do the following things:

  • If your warranty has expired, contact Levoit customer support to get assistance with fixing the light issue.
  • Keep in mind that the LV-PUR131S and LV-PUR131 models are particularly prone to these types of issues.
