Learning how to clean vacuum filters can save a lot of money in the long run. It’s important to remember that not every dirty filter can be washed. That includes the filters in some top-rated vacuum cleaners. Trying to clean certain types of vacuum filters can result in severe damage to the filter.


  • Only vacuum filters explicitly designed to be washable should ever be cleaned by you.
  • The most significant sign that you need to clean or replace the filter in your vacuum is the loss of suction power, so keep an eye out for that.
  • Washing reusable filters isn’t a very long process and should take you no longer than a few minutes, minus the time it will take to air dry.

How to Clean Vacuum Filters

Before you learn how to clean vacuum filters, you need to know what type of filter you’re dealing with, and how to clean your vacuum cleaner. Different brands have different requirements for care, which will be easily found in the cleaning instructions for the filter. The steps will be almost the same for the majority of filters, however.

Why Cleaning Filters is Important

There are many reasons why keeping your vacuum cleaner filter clean is crucial. Here are a few of them:

  • Dirty filters can cause an unpleasant odor
  • Regular cleaning helps maintain strong suction
  • Clean filters help with maintaining high air quality
  • The chance of mold growth increases with dirty filters

1. Gather Your Supplies

Once you know what kind of filter you’re dealing with, you can gather whatever supplies you need. While this list will vary from filter to filter, here is a general list of what you might expect:

  • Screwdriver
  • Gloves
  • Trashcan
  • Soapy Water
  • Mild detergent

2. Remove Your Vacuum Filter

Perhaps the least simple step, figuring out how to remove the filter, will take a little thought. Some of them easily pop out, and others will need a screwdriver for removal. Check the instruction manual for more direction on how you should remove your filter.

Some filters can be cleaned with mild detergent, too, which can improve your cleaning performance.

3. Clean the Filter Thoroughly

You can do this in a couple of different ways. The best way to do it is to run room temperature or warm water over the filter gently. Be careful not to touch the filter itself as this could harm it. This is especially true of HEPA filters. Some filters can be cleaned with mild detergent, too, which can improve your cleaning performance.

4. Allow For Thorough Airdrying

Now that you’ve gone through the cleaning process for your filter, it’s time to allow it to air dry. Skipping this step could alter the cleaning efficiency of the process. Both mold spores and mildew love growing in dark, wet environments, and leaving a filter even a little damp could cause an outbreak of either. It’s suggested that you leave the filter to dry for at least an hour.

5. Reinstall the Filter in Your Vacuum

The last step will be placing the filter back into your vacuum. In addition, if you want to improve the overall performance of your vacuum, consider learning how to clean the vacuum hose and other major parts of your appliance.

Why might cleaning a HEPA air filter be a bad idea?

HEPA filters are created in a way that makes them highly sensitive to outside interference. Attempted cleaning will irreversibly damage the tightly woven fibers. This mesh allows the filter to do its job, so unless it is specifically designed to be washable, you should never attempt to reuse your filter.

When should I replace Shark vacuum filters?

Always check the instruction manual that comes with your vacuum or the packaging the filter came in. Both will tell you when a good time to replace your filter is.

Where can I get filters and replacement parts for my Shark products?

There are a few different options for Shark products. The best way to go about it is to visit their official website.

Do products on the Dyson V-series only come with one filter?

Most Dyson V-series products will come with a filter. However, you can always upgrade to a better filter if you’d like cleaner air and a better experience. Just make sure that you reach out to customer service and ensure that the filter you purchase is compatible with your Dyson-V series model.

STAT: Remember: A HEPA filter consists of tightly woven fibers, and washing or scrubbing it is likely to affect the condition of the fibers, which in turn makes the filter less effective at cleaning 99%+ of microscopic particles. (source)
