A liquid filter apparatus and system is provided. The liquid filter apparatus and system is especially suitable for purifying water. The apparatus and system may have a solid portion and/or a porous filter portion called a monolithic unit. The present apparatus and system is suitable for providing clean water for drinking, cooking, washing and other household, public, medical, agricultural and industrial uses. The present apparatus and system utilizes anti-bacterial, anti-viral, anti-fungal, anti-mold and/or other cleansing elements to purify the liquid. The liquid passing through the system must pass through the monolithic unit which is solid and porous therein contacting the antimicrobial material and/or antimicrobial components located within the monolithic unit. The apparatus and system provide a high hydraulic conductivity as a result of the solid and porous nature of the monolithic unit.
