Those that have an air purifier know that once you get one, you notice the difference in the freshness of your space. But if you neglect your air purifier’s filter, all of those particles come floating right back into your home. To keep your air purifier recycling and refreshing your air, follow this guide on how to clean dyson air purifier filter and maintain a healthy, clean environment.

For an air purifier to be effective, its filter needs to be cleaned regularly. If this isn’t done, the filter becomes full of dust and debris and isn’t able to filter out anymore from your air, putting your homes air quality back at risk. The dust, pet dander, smoke particles, allergens, and dirt that exists in your home air can be making your living space uncomfortable without you even realizing it.

Why It Is Important to Clean Your Air Purifier Filter

Air purifiers work to remove harmful toxins and pollutants from the air that we can’t even see. Thankfully, you don’t need to worry about these particles as long as your air purifier is around unless you’ve been neglecting the filter.

Neglecting to regularly clean your air purifier’s filter can lead to a build of dust, dander, dirt, and more substances that the air purifier takes in, so you don’t have to. If the filter becomes loaded down with these particles, it isn’t able to remove more from your air and is forced to allow it to filter back into your breathing space.

If you suffer from allergies, headaches, or respiratory disease, air purifiers can be a lifesaving appliance. But you aren’t reaping any of the benefits if you allow the filter to be dirty. Simply put, your air purifier is useless without a clean filter to trap the toxins.

How to Clean Your Dyson Air Purifier Filter

These are the five steps Dyson recommends you follow to clean your air purifier filter thoroughly.

Turn Off/ Unplug

This may seem obvious, but many people neglect to shut off their air purifiers before attempting to clean them. This can result in breaking the machine, so make sure to turn it off and unplug it before you begin.

Remove Your Dyson Filter

The location of the filters differs between models. Your owner’s guide will show you exactly where the filter is located on your air purifier. But on most Dyson purifiers, the filter is purple and located near the cyclone part, usually just underneath.

Some Dyson air purifiers have more than one filter, so remove all filters at this time to clean them.

Wash Filters

Dyson filters can only be washed in cold water, or they will be damaged. This is very important to remember, or you’ll have to buy a new filter, which should only be necessary about once a year.

When you remove the filter, gently tap it against your hand over a trash barrel to get rid of the loose debris and dust on the surface. Once you have removed as much as you can, place the filter in your sink and run it over cold water.

Do not use a washing machine, dishwasher, detergent, soap, or anything other than cold water. Rinse the filter and then squeeze out the water. Continue doing so until the water comes out clean and you can’t see any more dirt on the filter.

Dry filters

Dyson air purifier filters should air dry only. Do not put them in a tumble dryer or microwave. Allow them to air dry in a warm place, but not near a fire or other open flame that could set it on fire. The filters should take about 24 hours to dry completely.

Replace the Filters

And that’s it! Once you put the filter or filters snugly back in their spot, the air purifier should be ready to start cleaning your air again so you can breathe comfortably despite outside toxins.

Dyson Air Purifier Maintenance Tips

Clean Filters

Of course, this is why you are reading this, but it’s a good reminder anyway! Clean and replace your filters as recommended to keep the air purifier working to cleanse your air.

Position Properly

Make sure your purifier is at least 6 inches away from walls and furniture, so it has enough space to pull in air. Placing it too close to other things can lower its efficiency or cause t to overheat from being crowded.

Close Doors and Windows

When you have doors and windows open where your air purifier is, it means the purifier has to work extra hard to purify the air. This can cause a lot of wear on the unit and prevent it from performing at capacity. It may even overheat if it is overwhelmed with polluted air.

Clean the Unit

The filters aren’t the only thing that needs to be cleaned. Wiping down your air purifier keeps it operating at optimal levels. A dirty air purifier can even start to grow mold if it becomes damp.

Bottom Line

An air purifier is only as good as its filter. So make sure you are keeping your air purifier filter in good working condition so you can breathe clean, refreshing air at home all the time.

Neglecting your air purifier’s filter will result in polluted air, which is harmful to your health and well-being. Clean your filters to keep your home clean and comfortable!


How often should I clean my filter?

Dyson recommends cleaning your air purifier filter once a month to remove dust and debris that has built up. If you wait too long to clean the filter, it wears down the filter as well as the air purifier. This means the unit may not last as long as it could if maintained properly.

How often should I replace my filter?

Even if you keep your filter pristine, it still needs to be replaced once a year. Filters that are used and washed regularly begin to break down and become less effective in trapping smaller particles.

What is the best air purifier filter?

HEPA filters are the best type of filter available for residential purifiers. They have multiple layers of different netting designed to trap particles of all sizes, so nothing gets released back into your breathing air.
