Carbon Block And Granular Carbon Filters
These are the most common style of countertop and under the sink systems (POU‚ point of use). Granular carbon filters
and carbon block systems basically perform using the same process of contaminant removal‚ adsorption‚ which is
the chemical or physical bond of a contaminant to the surface of the filter media. GAC‚ granular activated carbon‚
is recognized by the U.S. EPA as the best available technology for the removal of organic chemicals like herbicides‚
pesticides and industrial chemicals. Top 10 Brands Comparison
Multi-media block filters‚ like the Aquasana System‚
utilize the benefits of activated carbon with several added advantages. A blended media is extruded or compressed so that
the carbon and other media is in a solid form and can also filter out sediment and cyst type organisms... like Cryptosporidium
and Giardia. This configuration also prevents water from channeling around the filter media.

In recent years these types of filters have emerged as low cost alternatives to tap water and bottled water. Keeping in mind
that any filter is better than no filter‚ these products are by far the least effective and the most costly to use.
Pitchers and carafe filters are sold on the "Polaroid principal"... sell the camera cheap and make it up on the film sales.
The result is the same with these pour through pitcher filters‚ lower quality at a higher price. The average pitcher
filter sells for around $25 and includes one 30 gallon filter cartridge. Because of the small size of these cartridges they
have a very limited level of effectiveness and a low capacity. While pour-through filters do offer a slightly improved alternative
to tap water‚ they by no means can offer the quality‚ convenience and economy of the Aquasana System.
