This is a high quality after-market part and offers a great cost saving alternative to genuine. The filter is located at the top of the cyclone. We also stock and sell the post filters (if your machine uses one) Filters are fully washable. At this price you can buy a couple and keep one as a spare while the other is dryingThe internet can be a blessing and a curse at the same time for a business, however when we sell a filter for £6 and someone else is selling it for £1.50 with free delivery from China, you really do have to ask yourself what quality you are buying, just because they look the same does not mean they will perform or last the same. Our parts are priced on quality and the face to face customer service we can provide, we do however keep our prices as low and we can.
