The Blueair Blue Pure 221 Fabric Pre-Filter has been designed to capture large particles which enables a longer life-span for the main pre-filter in the air purifier. The Blueair Blue Pure 221 Fabric pre-filter is re-usable, meaning you are able to clean it by vacuuming the surface to remove the build-up of dust. There are a few colours to choose from so that you can select a colour better suited to your environment.
