The fabric pre-filter on the outside of your Rhino Filter provides the first line of odour filtration by removing the largest organic contaminates from the incoming air. Keeping a clean pre filter ensures the best performance from your filter. We recommend replacing the pre filter every 12 months or when it starts to look dirty.
