My DC05 has two filters: a washable one that basically looks like a sponge and the non-washable HEPA one that is a concertina of fine hairy papery stuff. From memory the HEPA is on the outflow so it doesn’t really get that dirty. I’ve replaced it once in 10 odd years.
one cat has that thing where he pulls his hair out so every morning
If you decide to get a new HEPA from dyson then check out their pet care kits too!
I stripped down my dyson and must say having seen its innards can confidently say that their ‘exclusive technology’ is all marketing and hype.
I’ve stripped mine too – but I didn’t have a suitable wind tunnel and airflow analysis system to test whether the cyclonic action was genuinely “exclusive” 🙂
