Why some people choose to filter Fluoride from their water

PF-2 Fluoride filters from Berkey Water Filter Systems were developed to reduce the fluoride in your water supply. Berkey developed the fluoride water filters to address the concerns many people have regarding the practice of adding fluoride to drinking water. Fluoride is being deliberately added to source water as common practice in many municipalities, this has been going on since the 1950's. It's becoming a more controversial practice the more research is being done to discover the harmful effects fluoride can have. Health and hygiene benefits of adding fluoride to the surface of teeth are well known and rarely disputed, however when fluoride is added to drinking water it touches the surface of the tooth in a very diluted form and for a short period of time before being swallowed and ingested. Critics say that in the age of high fluoride tooth pastes that have direct and prolonged contact, the need for fluoride in our water becomes questionable. The Berkey PF-2 Fluoride filters allow you to choose for yourself if you want to reduce the fluoride in your water by up to 97%.


What is the Lifespan of your PF-2 Water Filters?

Each set of Berkey® pf-2 filters is recommended to be replaced after 1000 gallons of water, or one year. For example, if you have a Big Berkey system (2 gallon capacity) and you refilled your system twice a day under normal conditions, you would be running 4 gallons of water through your pf-2 elements. Under these conditions, your set of 2 Berkey Fluoride Water Filter would last 250 days or a little over 8 months. Actual replacement period for your Berkey PF-2 Fluoride Filters depends on the amount of water you use and if there are high levels of fluoride or other harmful contaminants in your water. High levels of arsenic, fluoride and certain heavy metals can have a negative affect on the efficiency of the elements and the filtration flow rate.


Do I need to Prime my Berkey PF-2 Fluoride Filters?

Yes, in order to use your Berkey Fluoride Filters you have to prime them first. The filter element is very dense and contains dust from the manufacturing processes. The dust has to be rinsed out for the water to run clear and break the filtering media's surface tension. Once your PF-2 Fluoride Filter is primed, be sure to never allow the filter to dry out completely. If no water passes through for several days, the PF-2 Filters will need to be replaced.


Who Can Benefit from Adding Berkey Fluoride Filters to Their Berkey Water Filter System?

Berkey Fluoride Filters are a valuable addition to the Berkey Water Filter System, offering an extra layer of protection against fluoride and arsenic in drinking water. By removing up to 97% of these unwanted elements, these filters significantly enhance the quality and safety of your water. So, who can benefit from adding Berkey Fluoride Filters to their Berkey Water Filter System?

  1. Health-conscious individuals: Many people are becoming increasingly concerned about the potential health risks associated with fluoride in drinking water. By using Berkey Fluoride Filters, health-conscious individuals can reduce their fluoride exposure and protect themselves from potential health issues such as thyroid dysfunction, neurological problems, and dental fluorosis.

  2. Families with young children: Young children are more vulnerable to the effects of fluoride, as their developing bodies are more susceptible to absorbing this element. Parents who want to ensure their children's safety can greatly benefit from adding Berkey Fluoride Filters to their water filtration system, providing cleaner and healthier water for their family.

  3. People living in areas with high fluoride levels: In some regions, the water supply may have naturally high levels of fluoride or may be artificially fluoridated by municipal water treatment plants. For those living in such areas, adding Berkey Fluoride Filters to their water filter system can be a practical solution to reduce fluoride intake and minimize its potential health impacts.

  4. Residents in areas with arsenic contamination: In addition to fluoride removal, Berkey Fluoride Filters can also reduce the presence of arsenic in drinking water. Arsenic is a toxic element that can lead to serious health problems, including various types of cancer. People living in areas with known arsenic contamination can benefit from adding these filters to their Berkey Water Filter System to reduce their exposure to this harmful substance.

  5. Environmentally conscious consumers: By using Berkey Fluoride Filters, environmentally conscious individuals can reduce their reliance on bottled water and contribute to a more sustainable lifestyle. These filters provide an eco-friendly solution to obtaining clean and safe drinking water, minimizing the environmental footprint associated with plastic waste.

In summary, Berkey Fluoride Filters can benefit a wide range of individuals, including those who are health-conscious, families with young children, residents in areas with high fluoride or arsenic levels, and environmentally aware consumers. By incorporating these filters into their Berkey Water Filter System, users can enjoy cleaner, safer, and better-tasting drinking water, free from the concerns associated with fluoride and arsenic contamination.
