How Do Dyson Air Purifier Filters Work?

If you’re going to make an investment in a Dyson air purifier, you want to be sure it lasts as long as possible. Regularly swapping out the filter is key. In this guide, we’ll take a look at the different Dyson air purifier filter options and how to make the most of them. 

The efficacy of an air purifier depends largely on the type of filter and its quality. Dyson sells a varied range of air purifiers, all of which are equipped with true HEPA filters to trap allergens, odors, and bacteria. They’re pricey but offer impressive features and reliable performance. 

What Does a Dyson Air Purifier Filter Do?

Dyson air purifiers are engineered to deliver premium performance and their filters are designed with the same degree of care. 

An air purifier utilizes a fan to draw air into the machine, pulling it through one or more filters. The filters capture and neutralize particles, allowing clean air to be recirculated into the room. Air purifier filters are generally made from paper, mes  or fiberglass. 

Dyson air purifiers use 360° Glass HEPA filters. These filters are uniquely designed for Dyson air purifiers and backed by a 1-year warranty. They’re engineered to capture particles as small as allergens and viruses as well as smoke, bacteria, and mold spores.

Dyson’s HEPA filters are made from borosilicate microfibers that have been pleated hundreds of times to capture even the smallest particles. Dyson also offers activated carbon filters designed to remove odor and gasses like VOCs from the air. 

Types of Dyson Air Purifier Filter

An air purifier won’t do you any good if you don’t use the right filter and change it regularly. Without a proper filter, an air purifier will simply recirculate the air in the room. Some Dyson air purifiers also offer heating and cooling modes which will continue to function, but the unit won’t deliver the air purification benefits you want. 

Dyson offers the following six air purifiers:

• Dyson Pure Hot+Cool HP04 Purifying Heater plus Fan
• Dyson Pure Hot+Cool HP01 Purifying Heater plus Fan
• Dyson Purifier Cool Formaldehyde TP09
• Dyson Purifier Cool TP07
• Dyson Pure Cool TP01 Purifying Fan
• Dyson Purifier Humidify+Cool Formaldehyde PH04

Dyson air purifiers remove gasses and odors while capturing up to 99.97% of airborne particulate matter as small as 0.3 microns in size. These purifiers only use HEPA filters, but Dyson offers two main kinds. 

360° Glass HEPA Filter

This HEPA filter is fully sealed and made from borosilicate microfibers. Designed by the same engineers who created Dyson air purification systems, these filters are uniquely suited to Dyson purifiers and covered by a 1-year warranty. 

True HEPA filters, or high efficiency particulate air filters, are capable of removing at least 99.97% of airborne contaminants. This includes allergens like dust, pollen, and mold as well as pathogens like bacteria and viruses. These filters can remove particles as small as 0.3 microns in size, depending on the model. 

This filter is compatible with the following units:

• Dyson Pure Hot+Cool HP04 Purifying Heater plus Fan
• Dyson Pure Hot+Cool HP01 Purifying Heater plus Fan
• Dyson Pure Cool Link DP01 Desk Fan

As is true for all Dyson products, this filter comes with Dyson Expert support. 

360° Combi Glass HEPA + Carbon Filter

Engineered with the same HEPA technology as the previous model, this filter incorporates an additional mode of filtration: activated carbon. This filter is designed to filter gasses through a bed of activated charcoal which helps remove odor and volatile organic compounds (VOCs). 

This filter is compatible with the all following units:

• Dyson Purifier Cool Formaldehyde TP09
• Dyson Purifier Cool Formaldehyde HP09
• Dyson Purifier Cool TP07
• Dyson Purifier Hot+Cool HP07
• Dyson Pure Humidfy+Cool Cryptomic PH04
• Dyson Pure Humidfy+Cool Cryptomic PH02
• Dyson Pure Humidfy+Cool PH03
• Dyson Pure Humidfy+Cool PH01
• Dyson Pure Hot+Cool Cryptomic HP06
• Dyson Pure Cool Cryptomic TP06
• Dyson Pure Hot+Cool HP04
• Dyson Pure Cool TP04 Purifying Tower Fan
• Dyson Pure Cool DP04 Purifying Desk Fan

All Dyson air purifier filters are covered by a 1-year warranty and come with Dyson Expert support. 

How Often Should You Change a Filter?

The efficacy of an air purifier is only as strong as the condition of the filter. Over time, filters can become clogged with pollutants. Not only does that inhibit the function of the purifier, but it could result in unpleasant odors being circulated out into the room. 

Dyson recommends changing their air purifier filters every 12 months. You can purchase replacement filters anywhere you can buy Dyson air purifiers and they’re easy to change. 

Here’s how to replace a Dyson air purifier filter:

1. Be carefully Turn off the air purifier and unplug it.
2. Unlock and remove the outer cover on the base of the purifier.
3. Set the catalytic filter aside – it never needs to be changed.
4. Remove the old HEPA and carbon filters and discard them.
5. Attach the halves of the new HEPA filter to the outer covers.
6. Replace the covers on the air purifier.
7. Plug in the air purifier and then turn it back on.
8. Reset the filter life by pressing and holding the Night Mode button for 5 seconds.
9. Once the confirmation screen appears, the purifier is ready to use.

Monitoring the life of your air purifier filter is easy through the Dyson Link app. Most Dyson filters are also equipped with a filter change warning. Make sure to reset the filter life each time you change the filter so you know when it’s time to change it next. 

Bottom Line

When it comes to choosing an air purifier, it’s worth considering the type of filter it uses. Some filters work well for removing solid particles like dust and dander from the air while others offer more comprehensive purification. 

With the right filter, your Dyson air purifier can deliver years of reliable function. Take what you’ve learned here to select the right filter and to maintain your purifier properly.
