N. 1 point of use distillation is a collection of evaporated water, which is converted back into a liquid. Good for removing bacteria and compounds such as lead, magnesium and calcium, but does not destroy organic chemicals. A carbon filter should be used in this method. This is a slow process and the cost of 20 -26 cents a gallon.
# 2 reverse osmosis home water filters for water power in part through a permeable membrane with a fineporous structure only allowing molecules the same size as water to pass through. Most contaminants are of a larger molecular size than water so are left behind, including important health giving minerals. Other contaminants are smaller. A carbon filter should also be used in addition to R/O to filter out the remaining contaminants. Adequate water pressure is required to use this system. The system is slow, a lot of water is wasted in this process and expensive to maintain. The cost is 18 - 24 cents per gallon.
#3 Pitchers and Carafe-Style Filters are cheap to buy and the least effective of all home water filters. They are retail for around .00 and come with a 30 gallon cartridge. They only offer a slight improvement on tap water.
#4 Carbon Block and Granular Carbon Filters are the most common in counter top and under counter systems. These systems work the same way, by which the contaminant adheres to the filter surface. Very good for filtering VOCs and THMs. Activated carbon is recognized by the U.S EPA as the best available to to filter out these contaminants.
#5 Multi-media Block Filters use activated carbon with other added advantages. A combination media is changed into a solid form with a sub-micron pore like structure to filter out cysts such as Giardia and Cryptosporidium and other sediment. This system also prevents water from tracking around the filter media. In other words every part of this filter is foolproof.The cost is 10 cents per gallon.
