FILTER FOR PURIFYING DOMESTIC DRINKING WATER

摘要

An improved filter is provided for lowering levels of contaminants in domestic drinking water. The filter conains an oxidized activated carbon and at least one other type of adsorbent to remove cationic species and at least one other contaminant. The filter further achieves an efficient use of the adsorbents by including an envelope containing part or all of the adsorbents, which envelope minimizes the potential for flow by-pass.
