How to replace your Dyson air purifier’s filter

The filter in your Dyson air purifier needs to be replaced at least around the 12-month mark. If you are unsure how to replace it or forgot how to assemble your Dyson, this guide is for you.

If you aren’t sure if the filter on your machine needs replacing, you can check it through the Dyson Link app.

Here’s how to check:

  • Open the Dyson link app
  • Tap on the cogwheel in the top right corner to open the Settings 
  • And then tap on Your machine’s settings 
  • Scroll down until you are in the Air section. From there, you will see the health of your filter. 

Dyson will also alert you if your filter is already at the end of its life. The display on the machine will also show you if your filter is at its end. You can check a video version of this how-to here:

If it’s time to replace your Dyson purifier’s filter, this is what you need to do:

  • Unplug the machine first, then remove its outer covers. (In my case, it’s the Dyson Purifier Cool Formaldehyde.) I had it for almost a year before I got the alert that the filter needed to be replaced.
  • Once you’ve removed the covers, try to clean out the accumulated dust before you take out the used filter.
  • After removing the old filter, replace it with your new one. 
  • Again, try to remove the dust from the outer cover so you can start fresh. The catalytic filter installed in your Dyson air purifier doesn’t need to be replaced. Just leave that alone but remove any dust that might’ve stuck to it.
  • When you’re done sliding the filter parts into the outer covers, reattach them to your Dyson machine.
  • After that, plug it in and switch it on.
  • Press and hold the Night Mode button on the remote (the moon-shaped button) for around five seconds to reset your filter life. You should see the machine resetting the filter on its display.
  • When that’s done, you can check the status of your filter over on the Dyson Link app.

This is a small reminder, but check what model you have before buying your filter.
