I have a trusty old DC-14 All-floors. The post-motor filter is now dark grey and looks like it needs replacing.
The existing filter appears to be stuck on - presumably I need to tear it off and glue on a new one - what glue?
But can I upgrade it to a HEPA post-motor filter? Will one fit in the same housing? My son has been identified as having a dust mite allergy, and it might help his health in the house. If so, I presume I need the filter plus 2 seals?
