Keeping your air purifier running at peak performance is crucial for maintaining a healthy indoor environment. But over time, the filters inside can become clogged with dust, pollen, and other airborne particles. When this happens, your air purifier’s efficiency starts to decline. The solution? Resetting the filter.

This simple maintenance task can breathe new life into your air purifier, restoring its ability to capture irritants and pollutants. This blog will walk you through the step-by-step process of resetting your air purifier filter.

Whether you have a Levoit, Coway, or any other brand, you’ll learn the tips and tricks to get your machine working like new.

Common Signs that a Reset is Needed

Knowing when it’s time to reset your air purifier’s filter is key to maintaining optimal performance and air quality. Here are some common signs that indicate a filter reset is necessary:

1. Unresponsive Controls: If you notice that the buttons or settings on your air purifier are no longer responding as they should, it may be time for a filter reset. This could mean the controls feel “stuck” or the display is not updating properly.

2. Error Messages: Many air purifiers will display error codes or warning messages when the filter needs to be reset. These alerts are the device’s way of letting you know maintenance is required.

3. Reduced Airflow: Over time, a clogged filter can restrict the airflow from your purifier, making it feel less powerful. If you notice a significant drop in air circulation, that’s a sign the filter needs attention.

4. Increasing Odors: As the filter becomes less effective, it may struggle to capture odors and VOCs (volatile organic compounds) in the air. If you start noticing more persistent smells, it’s time for a filter reset.

5. Declining Air Quality: The ultimate indicator is if you simply feel the air quality in your home has deteriorated. If allergies, asthma symptoms, or general staleness seem to be creeping back, the filter likely needs to be reset.

Paying attention to these common signs will help you stay on top of your air purifier’s maintenance needs. Resetting the filter at the first indication of issues will ensure your device continues providing fresh, clean air for your home.

Step-by-Step Guide on How to Reset an Air Purifier Filter

Resetting the filter on your air purifier is a straightforward process, but the specific steps can vary depending on the make and model. In this guide, we’ll cover the general reset procedure as well as instructions for some of the most popular air purifier brands.

Common Filter Reset Steps

1. Locate the Filter Reset Button/Indicator

The first and most crucial step is to find where the filter reset functionality is located on your specific air purifier model. This can vary quite a bit across brands and product lines.

Some common places to look include:

  • On the control panel of the air purifier, either as a physical button or a digital indicator
  • On the remote control (if your air purifier comes with one)
  • In the settings menu of a companion mobile app (for smart/connected air purifiers)

Carefully review your air purifier’s user manual or the manufacturer’s website to identify the exact location of the reset button or indicator for your model.

2. Power Down the Air Purifier

Before attempting to reset the filter, you’ll want to power down and unplug the air purifier from the electrical outlet. This ensures the reset process is properly initiated and registered by the device.

Some air purifier models may require you to remove the filter housing or access panel to reach the reset button. Make sure to follow any specific instructions provided by the manufacturer.

3. Press and Hold the Reset Button

Once you’ve located the reset button or control, press and hold it for the recommended duration. This is typically around 3-5 seconds, but the exact timing may vary.

Pay close attention to any visual or auditory cues that indicate the reset has been successful. This could be a blinking light, a confirmation tone, or a change in the filter indicator on the display.

4. Verify the Filter Reset

After pressing the reset button, check the filter indicator light or digital display to confirm the reset was successful. The filter life indicator should now show a full or reset status.

If the reset doesn’t seem to have taken or the indicator light remains unchanged, you may need to repeat the reset process or refer to the troubleshooting section of your air purifier’s manual.

5. Power On and Resume Normal Use

With the filter reset complete, you can now plug your air purifier back in and turn it on. The device should now be ready to continue operating at optimal performance levels.

Remember to keep an eye on the filter indicator going forward, as you’ll need to reset it again when the filter life is nearing its end. Regular filter maintenance is key to ensuring your air purifier maintains clean, healthy air in your home or office.

Troubleshooting Common Resetting Issues

Resetting the filter on your air purifier is a straightforward process, but sometimes you may run into problems.

Here are some troubleshooting tips to address common issues that can arise during the reset procedure:

1. Filter Reset Button Not Responding

If you’re pressing the reset button but nothing seems to happen, there are a few things to check:

  • Power Down the Unit: Make sure your air purifier is completely powered off and unplugged from the outlet before attempting the reset. This ensures the reset process can be properly initiated.
  • Check the Reset Duration: Consult your air purifier’s manual to verify the recommended length of time you should press and hold the reset button. This is typically around 3-5 seconds, but can vary by model.
  • Locate the Correct Button: Ensure you’re pressing the right button or combination of buttons to trigger the reset. The reset function is often a dedicated button, but some models may require a specific sequence.
  • Inspect for Obstructions: If your air purifier has a removable filter housing or access panel, make sure there are no physical obstructions preventing you from properly engaging the reset button.

If the reset button still doesn’t respond after trying these troubleshooting steps, there may be an internal issue with your air purifier’s reset mechanism. In this case, you should contact the manufacturer for further assistance.

2. Filter Indicator Light Doesn’t Reset

After pressing the reset button, you should see the filter life indicator light or display change to confirm the reset was successful. If this doesn’t happen:

  • Verify the Reset Process: Carefully watch the indicator light or digital display during the reset process. Make sure you’re pressing the button for the full recommended duration.
  • Clear Any Obstructions: Ensure there’s no dust, debris or other physical interference around the filter indicator that could be preventing it from updating properly.
  • Try Resetting Again: If the light doesn’t change the first time, repeat the reset process. You may need to hold the button slightly longer.
  • Check for Digital Indicators: Some air purifiers now have filter life tracked digitally via a companion app. There may be a separate reset option within the app you need to use.

If the filter indicator still won’t reset after multiple attempts, there could be a sensor or electronics issue with your air purifier. Contact the manufacturer for troubleshooting support.

3. Filter Life Still Shown as Expired

In some cases, completing the reset process doesn’t fully clear the filter life counter. If the filter is still indicated as expired:

  • Perform a Double Reset: Try resetting the filter a second time to ensure the counter is properly cleared.
  • Utilize Digital Reset Options: Check if your air purifier model has a reset function within a companion mobile app. This may provide an alternative way to reset the filter life.
  • Replace the Physical Filter: If the reset isn’t working, the issue may be with the filter itself. Replacing the filter cartridge before resetting could resolve the problem.

Tips for Maintaining and Maximizing Air Purifier Performance

Maintaining your air purifier to keep it running at optimal efficiency is essential for providing clean, healthy indoor air. Here are some tips to help you maintain and maximize the performance of your air purifier:

1. Replace Filters Regularly

The filters inside your air purifier are the workhorses, capturing airborne pollutants and allergens. Over time, these filters become clogged and less effective. Consult your owner’s manual to determine the recommended filter replacement schedule, typically every 6-12 months.

2. Reset Filters When Needed

In between full filter replacements, you may need to reset the filter indicator light or counter. This tells the air purifier that the current filter has been refreshed and can continue operating at peak efficiency. Refer to the brand-specific reset instructions for your model.

3. Clean Pre-Filters

Many air purifiers have removable pre-filters that capture larger particles before they reach the main filter. These pre-filters should be cleaned monthly by vacuuming or wiping them down to maintain airflow.

4. Check for Obstructions

Make sure there are no objects or furniture blocking the air intake and output vents of your air purifier. Unrestricted airflow is crucial for optimal performance.

5. Use on the Appropriate Setting

Running your air purifier on the highest fan setting may seem like the best approach, but this can actually decrease its efficiency over time. Use the “Auto” mode or run it on a lower setting when possible to prolong filter life.

6. Monitor Filter Life Indicators

Keep an eye on the filter life indicator light or display on your air purifier. This will let you know when it’s time to reset or replace the filter, ensuring consistent air cleaning.

7. Consider Room Size

Make sure your air purifier is sized appropriately for the square footage of the room it’s placed in. An underpowered unit will struggle to clean the air effectively.

8. Schedule Regular Maintenance

Set reminders to perform routine maintenance tasks like cleaning pre-filters and resetting the filter. This will help you stay on top of air purifier upkeep and maximize its performance.
