Still Locked? Try Different Combinations On Your Levoit Air Purifier & Check The Manuals

Suppose you can’t unlock your Levoit Air Purifier after trying the abovementioned steps. In that case, there may be a combination of buttons that you need to press. The exact mix will depend on your model, so it’s best to consult your purifier manual for more information. Some common varieties include:

  1. Press and hold the lock button while simultaneously pressing the power button.
  2. Press and hold the lock button, then press the filter reset button.
  3. Press the lock button, the change filter light button, and the power button.

Remember, these combinations may not apply to all models, so it’s essential to check your purifier manual for the correct instructions.

Additional Information On Levoit Air Purifiers

While working with your Levoit Air Purifier, it’s also an excellent time to check if the filter needs replacement. Look for the change filter light on your device. If it’s lit, it’s time to replace the filter. Most Levoit air purifiers use a combination of HEPA filters and activated carbon filters to remove allergens, dust, and odors from the air. Replacing these filters, as your purifier manual recommends, is essential to maintain optimal performance.

When replacing the filter, press the filter reset button after installing the new one. This will reset the filter life timer and ensure your device continues to work efficiently. Consult your purifier manual for step-by-step instructions if you need help replacing the filter. Many Levoit filters, like the Levoit 300, can be easily found online or at your local home improvement store.

Another useful Levoit product is the Levoit humidifier. Just like air purifiers, Levoit humidifiers can improve the air quality in your home by maintaining optimal humidity levels. This can help with allergies, dry skin, and overall comfort. If you want to learn more about Levoit humidifiers, check out their website or online reviews for more information.


Unlocking your Levoit air purifier is a simple process. Still, it is easier if you know the specific model. You can easily unlock your device by following the steps outlined in this guide and referring to your purifier manual. Remember to check the change filter light and replace the filter as needed to ensure your air purifier continues to work efficiently. Give it a good cleaning, too!
