Each Phresh Filter comes with two outer filters, which can be easily mounted around the filter with a Velcro seam. We supply two filters so you can replace the outer filter regularly and can wash the dirty filter at your own convenience.We recommend to change and clean the filter 2-4 times a year, depending on the level of saturation.
To easily connect ducting we supply 4 ducting clips. It is sometimes very hard to keep the ducting on the flange when you install it, especially when for example you are working in confined spaces ot high over your head. With the ducting clips installed on the flange, the ducting will not slide back from the flange, enabling you to connect it easier. Especially when you install insulated ducting this can be a real time saver. If you use single ducting we recommend to tape the ducting when using the clips, as they penetrate the ducting.
