How do I clean the filter on my nuwave air purifier?

Keeping the filter on your Nuwave air purifier clean is one of the most important maintenance tasks. A dirty filter will reduce the air purifier’s effectiveness at removing pollutants from the air. Here is a step-by-step guide on how to clean the filter on a Nuwave air purifier.

When to Clean the Filter

Most experts recommend cleaning the filter on your Nuwave air purifier every 2-4 weeks. However, if you live in an area with high pollution levels or have pets that shed a lot of dander and hair, you may need to clean it more frequently. Here are some signs that indicate it’s time to clean the filter:

  • Increased noise when the purifier is running
  • Reduced airflow coming out of the vents
  • The filter looks visibly dirty
  • The indicator light is flashing red

Cleaning the filter regularly will maximize your air purifier’s effectiveness and extend the life of the filter. Nuwave recommends replacing the filter every 6-8 months, but more frequent cleaning can help the filter last longer.

Supplies Needed

Before cleaning the Nuwave filter, make sure you have the following supplies:

  • Replacement filter (if it’s time for a new one)
  • Soft brush or vacuum cleaner hose attachment
  • Sink, tub or outdoor hose
  • Mild detergent and water
  • Clean towel

You may also want rubber gloves to protect your hands.

Step-by-Step Filter Cleaning

Follow these steps to properly clean the filter in your Nuwave air purifier:

  1. Turn off and unplug the purifier. Make sure the purifier is powered off before doing any work on it.

  2. Open the filter housing. The housing is located on the back or side of the unit. Lift off the cover to access the filter.

  3. Remove the filter. Gently pull it out of the housing. Don’t try to clean the filter while it’s still inside the housing.

  4. Use brush attachment or hose to remove loose debris. Gently vacuum the filter to pick up any loose hair, dust and particles. Make sure not to tear or damage the filter material.

  5. Rinse the filter with water. Run the filter under lukewarm water to rinse away remaining debris and dust. Let the water run through both sides.

  6. Mix mild detergent with water. Use a small amount of natural, biodegradable detergent and lukewarm water in a sink, tub or with an outdoor hose.

  7. Soak and hand wash the filter. Submerge the filter in the detergent solution and gently scrub both sides using your hands or a soft brush. Avoid harsh scrubbing.

  8. Rinse thoroughly. Rinse the filter again under running water until all suds and detergent are gone.

  9. Air dry the filter. Shake excess water off the filter and let it completely air dry for at least 24 hours before returning it to the purifier. Lay it flat or stand it on its edge.

  10. Check for damage before reinstalling. Inspect the filter for any tears or cracks. Replace it if it is damaged.

  11. Insert filter back into housing. Once fully dry, carefully slide the filter back into the housing. Make sure it fits snugly.

  12. Replace housing and power on purifier. Put the housing cover back on securely and plug the power cord back in.

Tips for Effective Filter Cleaning

Follow these tips to get the most out of cleaning the filter:

  • Be gentle when handling the filter to avoid tearing.
  • Never use harsh chemical cleaners, bleaches or soaps.
  • Allow proper drying time before reusing filter.
  • Rinse thoroughly to prevent soapy residue on filter.
  • Check manufacturer guidelines on cleaning frequency.
  • Consider having a spare filter on hand for easy replacing.
  • Clean fan blades and interior housing periodically.

Replacing the Filter

Over time, the filter will wear out and need to be replaced. Most Nuwave air purifier filters should be replaced every 6-8 months. Here are some signs it’s time for a new filter:

  • The filter has visible tearing or cracking.
  • It is over 8 months old.
  • Decreased airflow continues after cleaning.
  • The filter has a musty or dirty odor after cleaning.

Nuwave air purifiers use filters specific to the model. When purchasing a replacement, check the owner’s manual for the right part number. Confirm the filter dimensions match those for your model. Slide the old filter out and insert a new one following the cleaning steps above.


Regularly cleaning the filter in your Nuwave air purifier is essential for keeping the air in your home pure and pollution-free. Follow the steps outlined above, being careful not to damage the delicate filter material. With proper maintenance, your air purifier will run efficiently for years to come.
