Silver Nano Carbon Block versus Granular Silver Nano:
The Silver Nano Carbon Filters come in two different versions: Silver Nano Carbon Block & the Granular Silver Nano Carbon.
Both versions will remove Chlorine, organic molecules, and sediment. And both versions use Silver Nanoparticles to help inhibit and prevent the growth of bacteria inside the filter.
There are, however, several key differences between them;
Carbon Dust and Flushing Time:
The Granular Silver Nano Filter contains loose, individual granules of carbon (think of it like coarse sand or coffee grounds). Because the particles can shift and rub against each other during shipping and handling, they create a lot of fine carbon dust. That's why it requires a longer initial flush—usually a few gallons or several minutes—until the water runs clear.
Whereas the Silver Nano Carbon Block uses the same carbon and silver nanoparticles, but it is instead compressed with a binding agent into a solid, rigid block. Because the carbon is locked in place, there is almost no friction between particles, resulting in drastically less carbon dust and a much quicker flushing time.
Filteration Effectiveness:
Because Granular Silver Nano Carbon (GAC) consists of loose particles, water will naturally find the easiest path through them. Over time, water carves a literal "channel" through the granules. Once this happens, the water rushes through that single path, bypassing most of the carbon and silver, drastically reducing the filter's effectiveness.
The Silver Nano Carbon block, on the other hand, is a solid, uniform wall of carbon. So water cannot create a shortcut; it is forced to pass evenly through microscopic pores. This ensures maximum contact time with both the carbon and the anti-bacterial silver nanoparticles, resulting in a much more consistent filtration effectiveness over time.
Both the Silver Nano "Block" Fridge Filter and Granular Fridge Filter also come in several versions:
