Review on Filter Coconut Granular Activated Charcoal by Isaac Simpson

I use this in my home made water filter and it works very well. They need to have some other filter material at the top and bottom to keep the smaller charcoal particles in place - we use the clear PE wadding they sell for pillow stuffing. This setup certainly can't remove bacteria or other beasts that might pose a risk to your health, but it does make our safe-yet-fancy tap water taste better and cost much, much less than commercial filter cartridges.
