Are dirty filters harming your vacuum cleaners suction? Watch the latest eSpares video to find out how to remove and replace the pre- and post-motor filters on a Dyson DC04 vacuum cleaner.
Hi, I'm Rory from eSpares, if your Dyson DC04 has lost suction, the most probable cause is the filters in the vacuum becoming dirty or clogged.
Now there's 2 filters in the DCO4, there's this pre-motor filter which filters out fine dust particles which can cause allergies it's one spare but it comes apart. This is washable and must be washed every 6 months, and you do that by just running it under the tap, but if it's really filthy then I'd just get a new one. There's also this post-motor filter which you must be replaced regularly and isn't washable.
Now, I'm going to start by replacing the pre-motor filter just by opening the cyclone assembly, as you can see, this one is a bit mankey so just put that to one side and pop the new one in. As simple as that, I'm now going to replace the post-motor filter. I do that by removing the post-filter lid and putting it one side. As you can see as well, this one is absolutely horrible so just get rid of that, put in the new one and now I'm just going to replace the post-motor filter lid – make sure this is lined up correctly because, if not, it can easily break.
And now, I'm just going to put the cyclone and bin back on the vacuum, job done.
