Phresh Carbon filters are machine packed with 46mm (1.8") RC-48 activated, certified virgin carbon to ensure optimum and homogenous density and throughout the entire filter. The aluminium top and conical base (to improve air flow), as well as the 51% open mesh design means that these filters are much lighter than other filters of the equivalent size, giving extra peace of mind when suspending them above delicate plants or flowers. Phresh filters come with a pre-filter that helps increase the products' lifespan; remember to give the machine washable pre-filter a wash roughly once every 6 months. Try to avoid conditions over 35C in temperature and 75-80%+ humidity as this can reduce the lifespan of your filter. Ideal for use with any make of extraction fan we supply, though always make sure to choose the appropriate sized filter for the fan you are using. The perfect choice for complete odour control.
