How often do you need to change Dyson purifier filter? We recommend replacing your air purifier filter every 12 months. That’s because over time, filters can get clogged with pollutants, and even let unpleasant odors back into the room.
Are Dyson air purifier filters washable? The filter is not washable, and the best you could do in order to prolong its life is to vacuum it to get rid of some of the trapped dirt. Another turn off for current owners is how flimsy the construction feels. There is no denying that the Dyson Link Air Purifier looks sleek and modern.
