Pelican Whole House Water Filter Carbon Series Review
http://www.pelicanwater.com/whole_house_water_filters.php
You cannot beat the price and design of this system. It is the best deal hands down if you are looking for purified water. There is no need for high-end reverse osmosis or UV lights or anything of the like unless you have well water or very hard water. If you are looking for something that gives you better than bottled water, then this is it. I have done plenty of research of design and cost of systems for upfront and long run costs. The guess work for you ends here if you are looking for something that fits these needs.
I do not get paid to advertise for any company. This is just a rough video that hopefully will help make your decision a little easier.
