How to choose a quality filtration system
For drinking and point-of-use sink systems, look for the following features: multiple separate stages, full bed depth filters, at least one highly-rated granular activated carbon filter stage, and one highly-rated carbon block stage. Quality drinking system filters should last about 1 year.
Be aware that single-stage filters are for limited use or taste and odor only. Single-stage “multi-media” units that stack multiple types of filtration in one filter are not suitable filtration devices because there is not enough of one media to filter the water effectively.
Protection from absorbing contaminants through our skin and lungs during a shower or bath is just as important as having proper filtration at the sink. The need for central water filtration is no less a standard of health and home comfort than the standard of central heat and air conditioning.
High-quality home filtration systems will meet the following criteria: minimum 1000 iodine rating of carbon media, automatic backwashing to prolong filtration media lifespan and keep it from packing/channeling (“upflow” devices that do not backwash create a reverse channeling effect and have short life spans). In regards to multiple media (“multi-media”) systems, a tank would have to be 20 feet tall to contain all the different media to work as advertised. Stacked media in a tank is similar to stacked media in cartridges – there is not enough of any one media to be effective beyond simply improving taste. Quality whole home filtration should last a family of four on chlorinated (not chloramine-treated) about 10 years.
Filtration to the whole home is recommended by countless health authorities, including the President’s Cancer Panel, which stated, “filtering home tap water or well water can decrease exposure to numerous known or suspected carcinogens or endocrine-disrupting chemicals.”
On his national television program, Dr. Oz stated, “the most important thing I’m going to say today [is]...I don’t think you should be bathing your kids in the tub unless you know that water is clean. All those chemicals get absorbed through the skin, and therefore your child has been contaminated.”
