Hello, my first posting. I have a DC08 and quite a while ago I started using HEPA filters for the post motor filter. I have found that the pre motor washable filter now gets more debris on it and clogs more quickly especially with the larger bits of debris that always in the past were caught in the canister before it got to the pre motor filter.
My question is, due to the more restrictive HEPA filter has it affected the cyclone effect in the canister and the pre motor filter is now having to do alot more work ?
Thanks
