M Hesselink –
For years happy with our Duux Tube . I am now buying the 3rd filter. Coarse dust is easy to take off from outside. Inside are the fine filters and carbon, of course you can't clean them,so replace them occasionally. Filters are pricey though and I think it's a shame there is no recycling system for them, for example returning used filters for reuse of raw materials.
