This Dyson DC07HEPA Filter Kit includes a pre-motor washable filter and post-motor non-washable filter, these filters are for ALL Dyson DC07 models. The pre-motor filter is washable but the post-motor HEPA filter is not, the post-motor filter should be replaced at least once every 6 months.
If you notice that your Dyson has lost some of the suction since you've had it, cleaning and replacing the filter should be the first place to start.
PLEASE NOTE: The POST MOTOR FILTER can not be washed - when it is impregnated with dirt on both sides it must be changed.
