PORE SIZE of 0.2 to 0.5 micron (hum an hair is 40 to 300 microns) In other words, the stated pore size of filter isn’t literally the size of the pores. It’s a rating of what can’t pass through them. Obviously, when sterilizing water, the object is to physically remove particles suspended in the water. The smaller pore size a smaller amount of contaminates will pass them
SILVER IMPREGNATED A low-cost technology to treat water at the household level is the ceramic silver-impregnated filter. The ceramic filter is a promising treatment system to supply safe quality of water. Over time, the trapped dirt and contaminants will begin to buildup, forming a layer of gunk on the surface of the ceramic filter. or soft brush under cool running water will unclog the pores on ceramic and expose a new layer for use
