Yo mate, most filters have a shelf life, depending on the type of carbon used inside etc... but ive just found a filter that doubles as a silencer aswell,. you can either push air through it or use it in the traditional way of sucking air through = more room inside your grow area.
Plus it has a interchangeable filter inside, so you don't throw the whole thing away. you smash up the inside bit and can even sprinkle it all over your soil.
What makes this new type capable of all this is here, taken from their website : which im not posting! lol. Nope. Sticking to the rules like glue here,
just trying to inform is all, so here is some info; if you want more info just search for Bulldog filter.
