If you own a Dyson air purifier, you know it can effectively trap several airborne pollutants and promote healthy air. However, these contaminants eventually build up in the filters, reducing effectiveness. Cleaning the air purifier filters is essential to ensure proper working condition. 

You can clean a Dyson air purifier filter by using a vacuum to remove debris. You can also soak the filter in water. 

There are other steps to keep in mind to prevent damage and achieve a pristine filter. Below, we’ll cover the step-by-step process of cleaning a Dyson air purifier filter. But first, we’ll show you the signs that indicate your air purifier is already dirty.

How To Know When You Need to Clean the Dyson Air Purifier Filter?

There are a few signs that indicate your Dyson air purifier filter needs cleaning.

First, you’ll notice dust or other debris floating in the room. The filter is likely clogged, which reduces its effectiveness against airborne pollutants.

You might also experience an increase in allergies or respiratory problems if the filter is dirty. Remember that uncleaned and unfiltered air can irritate your airways, ultimately leading to breathing issues.

Do you notice a foul smell coming from the air purifier? That’s another sign the filter needs cleaning.

Finally, try the white sheet test if you’re still unsure whether to clean the air filter. This method involves placing the sheet in front of the air purifier vents. Leave it for an hour before coming back to check the sheet color. If it is still white, the filters are still working efficiently. But if the sheet turns gray, the air purifier already needs cleaning.

How to Clean A Dyson Air Purifier Filter?

Cleaning a Dyson air purifier filter is relatively easy. Below are the steps to follow to achieve a clean, sanitized fan filter.

Turn Off and Unplug the Air Purifier

The first thing you need to do is turn off the air purifier. Unplug it from the wall outlet to ensure your safety. Remember that water and electricity are not best friends. So disconnect the air purifier before carrying out any type of maintenance.

Remove the Dirty Filter From Its Housing

Next, you’ll need to disassemble the Dyson air purifier to access the dirty filter. Refer to the product manual for specific instructions on removing the old filter from the air purifier.

But in most Dyson air purifier models, you can find buttons on the side. Press these buttons to detach the air filter from the main body.

If you own an air purifier with multiple filters, like the 360-degree models, push the side buttons to lift the filter housing. Look for the arrows on the casing and press them to release the dirty filters.

Use a Vacuum or Brush to Remove Dirt

After removing the dirty filters from their housing, open them gently. You might want to wear gloves for this task because you’ll touch a lot of debris inside the filters.

Use a vacuum to suck all the debris and dirt on the air filters.

If you don’t own a vacuum cleaner, remove the dirt with a brush instead. You can also soak the brush in cold water to eliminate more stubborn particles. However, before doing so, check the Dyson product website to learn if the filters for your specific model are waterproof. Some units are not, so stick with a dry cleaning brush.

Rinse the Air Purifier Filter Under Cold Water

Are your air purifier filters still dirty after vacuuming or brushing? Consider rinsing them under cold water.

Again, make sure your Dyson air purifier has waterproof filters. You can easily check this information on the website. 

Use only cold water to clean the dirty filters. Avoid adding detergent or soap because it can affect the performance of the air purifier.

Instead, squeeze the dirty water out of the filters. Continue washing until you see the water is clear.

Allow The Filter to Dry

Once you’re done washing, allow the filters to dry. Leave them in a warm area away from direct sun for at least 24 hours. 

Do not put the filters inside a tumble dryer, microwave, or near a flame.

Also, avoid putting back wet filters in the air purifier, or you risk damaging the machine.

Reassemble the Air Purifier Filter

After the filters are completely dry, you can now return them to the housing. Snap them back in position.

Then, place the Dyson filter housing on the main body. Push it down gently until it locks into place. Avoid using excessive force because you risk damaging the inside mechanism of the air purifier.

Can You Wash A Dyson Air Purifier Filter?

You cannot wash a Dyson air purifier filter with detergent and soap. You’ll only damage the filter media with these cleaning items. Note that the interior fiber mesh easily gets stretched and torn. So even if the filter might seem intact after washing with a soapy solution, you can expect it to lose effectiveness.

If you want to clean a dirty air purifier filter, stick with the cold water rinse method. It involves dipping the filter under cold water to remove stubborn particles. Don’t forget to squeeze the dirty water out and dry the filter before placing it in the air purifier.

How Frequently Should You Clean the Filter?

You must regularly clean the filter to get the most out of your Dyson air purifier. But you might wonder: how frequently should I clean the filter?

It depends on several factors, including how often you use the Dyson filter and your current indoor air quality.

If you often use your Dyson air purifier, you’ll also need to clean its filters regularly. Vacuuming and rinsing once a month is ideal for achieving optimal performance. 

You must also clean the filters monthly if you have poor indoor air quality. For instance, if you have pets or a smoker, your house likely has increased levels of airborne pollutants. The air purifier will work harder to remove these particles and ensure healthy air quality. To make the task easier for the machine, sanitize the filters regularly. 

How Long Do The Dyson Air Purifier Filters Last?

The exact lifespan of Dyson air purifier filters depends on how often you use the machine.

In general, the filters can last you up to 12 months or a year.

However, the Dyson filters might lose effectiveness earlier than expected if you use the air purifier regularly. They may also stop working properly if they have accumulated stubborn dirt.

Regular cleaning can prolong the lifespan of Dyson air purifier filters. It also promotes healthy indoor air quality, which reduces the risk of respiratory problems. 

How Often Should You Change Your Dyson Air Purifier Filters?

No matter how often you clean them, Dyson air purifier filters cannot last you forever. You will eventually need to replace them with new ones.

We recommend changing the filters at least once every year.

However, consider the current indoor air quality of your home. This factor affects how often you need to change the filters.  

For instance, if you have a pet, know that it can shed dead skin, known as dander. This is usually a breeding ground for allergens, bacteria, and other harmful contaminants that escape into the air. 

Smoking also increases the number of airborne pollutants in your home. It’s best to replace the air filter every six months or earlier for optimal working conditions.
