Dyson Dc40 How To Clean Filters

Dyson DC40 Filter Replacement and Maintenance Guide

Your Dyson DC40 comes equipped with two filters; the Pre-Filter assembly located in the cyclone assembly of your machine, and the Post-Filter assembly located in the Ball. Both of these filters filter incoming and outgoing air for your Dyson DC40. Dyson recommends these filters be cleaned every 3 months, depending on the traffic type or usage. If your filters go without maintenance, your machine could be adversely impacted. Replacing overly-congested filters is also recommended.
