My 5 year old well maintained DC25 has just started having an issue where the post motor filter (inside the ball) won't stay clipped in.
I can't see any broken clips or any other cause for this.
Ironically, a neighbor who has a DC25 said that hers does this as well, so she runs without the post motor filter.
Anyone had this issue? Is there a fix besides getting a new filter? Does anyone run theirs without the filter in place?
To me,except for getting motor carbon dust into the air, and inside the ball, it shouldn't hurt the motor, and in fact may allow it to run cooler (the motor has always run hot anyway).
Besides the obvious "don't buy Dyson's" or "DC25's suck is why this is happening" responses, anyone having some personal experience or advice on what can be causing this issue please chime in.

The filter needs replacing.

They say they're washable lifetime filters but they DO need replacing after a few years.

It won't hurt the machine running without it, but filtration won't be so good.

If you do decide to replace it, ensure you buy a genuine Dyson part as the cheaper copy parts can be pretty poor and reduce airflow

Thanks matt8808

Kinda what I though the answer would be. I did wash the filter again thoroughly and used it for about twenty minutes and it stayed attached. But I'll have to see if running it longer, building up more heat, will cause it to pop off again. Perhaps I let it get a little too dirty and washing it will solve the problem, but we'll see. But thanks for the help!

The cause of this is the carbon dust. The carbon dust eventually becomes too much for the airflow so it gets blocked and the powerful motor is blowing it's exhaust really powerfully, so the air must go somewhere. The sealed filter is doing well but it becomes too much so it just pops the filter out. So unless you wash the filter REALLY well, the filter will continue to pop out.

The aftermarket filters work okay, not optimistically and are not recommended because the clips are large and in use the catch will make a clicking sound against the ball. As Matt mentioned, there's nothing wrong in removing the post moor filter and using the vacuum, however there is the consequence of non HEPA filtration so carbon dust will escape and it will be slightly louder and sound like a Dyson DC24 (the filter insulates sound aswell).

Hope this helps

The filters are 'washable' but in reality are not 100% recoverable.

Tayyab is correct that carbon from the motor is part of the filter loading- and this stuff cannot be removed however well you wash it...it actually bonds to the filter media.

I personally wouldn't run a machine without the filter solely for the noise...but if you don't mind that, then you probably won't notice the emissions except when picking up stuff like fire-ash.

Thanks to parwaz786 and purpledefector

I suspected that the filter may only work for a short while and that the pressure is popping the filter off at some point. This makes perfect sense! My other theory about the heat buildup contributing to it probably has no bearing. Thanks for the info, as I know that others have far more Dyson cred than I do. I will keep running it and see if perhaps I got it cleaned enough, because I know I let it go far too long this time, due to putting off cleaning the filters for another day. We'll see if the filter is used up or still can be cleaned and run for a while longer. Thanks again everyone!

The clips are known to move with age and not clip back in again, I've replaced them with 100% success every time.

Qualtex (in the UK) re-designed their post motor filter retaining clip to dial this out, and every one of the 4Home branded ones have been fine. If America has old stock this may still be an issue though
