We took an in-depth look into that claim and also discussed some potential alternatives. Why Use A Knock Box? A knock box could be an investment worth making for the following reasons- It Keeps The Portafilter Safe: When you try to expel the puck from the portafilter into your trash can, you would have to bang it against the palm of your hand or the side of your garbage bin to make sure all of it comes out. Doing so, there’s always a risk of damaging your portafilter and the trash can. If you use a dedicated knock box, it will effortlessly collect all the waste and keep your portafilter unharmed. To Avoid Odor Buildup: Wasted coffee grounds emanate an unpleasant smell. If you throw them in your trash can, the smell will disperse all over your place. Even when you clear out the trash, the odor might persist. A knock box traps the bad smell while storing old coffee grounds. You Can Store Old Coffee Grounds For Gardening: Old coffee grounds can be a rich fertilizer option for your garden beds. Knock boxes give you ample storage space for holding the residual coffee grounds so that you can later transfer them to a compost bin. Value for money and Easy to Maintain: Knock boxes are fairly espresso accessories, and they require minimal maintenance. Yes, you do need to wash them every once in a while. But, they are very easy to clean, easy to remove, easy to use, so you don’t need to give it much effort.
