The Ultimate Pre-Filter is used by many health-conscious Americans to remove chlorine, heavy metals, bacteria, sediments, fluoride, contaminants, and pollutants from their water before it is ionized and alkalized. The Ultimate Pre-Filter is a must for those who are serious about their health. This unit can be used as a pre-filter for water ionizers or as a stand-alone water filter for drinking. Diverter not included.
Pre-filters are water filters that are installed before the water enters the tap or the water ionizer or they can be used by themselves without a water ionizer. They require either counter-top housing or under-the-sink housing depending on your exact conditions, a volume of use and desire.
Stage 1 – Sediment Filter
Acts as a sieve to reduce solid particles such as rust flakes from water pipes, sand grains, small pieces of organic matter, clay particles, or any other small particles in the water. Average filter life span: 9-12 months
Stage 2 – GAC / KDF
Granulated Activated Charcoal filters remove many contaminants and impurities, utilizing chemical absorption. Carbon/charcoal filters are most effective at removing chlorine, sediment, and volatile organic compounds (VOCs) from the water.
A super heated carbon extrusion that forms carbon into a solid, yet porous block. Solid block carbon provides the properties of a sediment filter, while also increasing surface area. However, the flow rate can be significantly slower than granulated activated charcoal. Uses carbon to remove contaminants and impurities, utilizing chemical absorption. Block carbon is designed to provide a large section of surface area to allow contaminants the most possible exposure to the filter media. Carbon filters are most effective at removing chlorine, sediment, and volatile organic compounds (VOCs) from the water. All carbon filters will have reduced efficiency over time. Regular filter replacement is essential to good filter performance. If the taste of the water changes, after an extended period of non-use, such as after a vacation, it’s time to change the carbon filter. Average filter life span: 9-12 months
Stage 3 – Fluoride Filter
The Fluoride Reduction Pre-Filter cartridge contains fine-mesh pre-conditioned Activated Alumina to reduce fluoride 95%+ on most city water (typically <2 ppm). Lab tests show a capacity of 11,000 ppm with fluent levels below 0.2 ppm from 10 ppm feed (98%). Note: high pH and high bicarbonate levels reduce the capacity – above 100 ppm bicarbonate, reduce by 50%; above 200 ppm, reduce by 75%. Also effectively removes low levels of arsenic. Typical life for a family of four with typical city water is one year. Fits industry-standard slim-line housings. Not recommended by itself – it is best installed with a KDF/GAC cartridge following it (see above paragraph). Average filter life span: 9-12 months
Reasons To Use a Fluoride Reduction Pre-Filter
There are plenty of good reasons for installing a fluoride water filter. The fluoride that is added to water also contains other toxic materials and pollutants, which may include lead, mercury, and arsenic. Hundreds of renowned scientists and researchers around the world condemn or refuse to endorse fluoridation of the water supply. The fluoride water filter is a simple solution to a vexing problem. You may not have any control over what goes into your water, but this simple device can easily take it right back out.
Activated alumina filter media and carbon filtration are EPA and WQA recommended methods for removing fluoride from drinking water. A full cartridge of 100% activated alumina is needed to allow proper contact time for effective fluoride removal! Activated alumina is aluminum oxide, the same chemical substance as sapphire and rubies, but without the impurities that give the gems their color. (This is not aluminum, which is a more highly-processed metal made from activated alumina.) Activated alumina has a very high surface-area-to-weight ratio, with a lot of tunnel-like pores that run all through it. This means that there is a lot of surface area against which the water interacts, thereby removing fluoride (and arsenic). Through the attraction of the metals, 90% to 98% of fluoride (and arsenic) is normally removed. The fluoride coats the surface of the alumina over time and eventually the cartridge needs to be replaced (usually once a year for a family of four). We have been selling this activated alumina fluoride water filter for a long time and have many satisfied customers!
