Introduction to Pur Water Filters

By providing high-quality, convenient, affordable, and environmentally friendly water filtration products, Pur has become one of the most trusted and popular water filter brands globally.

Brief History of Pur

Pur is a brand of water filtration systems founded in 1986 by 24-year-old Harvard graduate Brian Sullivan. The brand was created to provide people with clean and safe drinking water worldwide. Over the years, Pur has become one of the most popular water filter brands globally, with a wide range of products designed to meet different needs and preferences.

In 1989, William Butler survived 66 days at sea with the PUR Survivor 35 – the first hand-operated Desalinator.

How Pur Became a Popular Water Filter Brand

Pur’s success can be attributed to its commitment to providing high-quality water filtration products that are both affordable and effective. In addition, the brand has invested heavily in research and development to develop innovative water filtration technologies capable of removing a wide range of contaminants from tap water.

Pur has also successfully created a strong brand image through its marketing efforts, which has helped increase awareness and loyalty among its customers.

In 1994, PUR invented the first faucet filtration system with Automatic Safety Monitor (ASM) gauge that lets consumers know when the filter is finished and can no longer remove contaminants.

Overview of Pur Filter Technology

Pur filters use a multi-stage filtration process that removes contaminants from tap water. The filters use mechanical and chemical filtration methods to remove particles, pollutants, and impurities from water. Some key technologies used in Pur filters include activated carbon, ion exchange resins, and mechanical filters. The filters are designed to provide safe and clean drinking water while maintaining the natural mineral balance of the water.

What is Fluoride and its Importance in Drinking Water

Fluoride is a naturally occurring chemical in water, soil, and some foods. Fluoride is well-known for its ability to strengthen teeth and prevent tooth decay, which is why it is often added to drinking water in small amounts.

Fluoride is considered an essential nutrient for dental health, and its presence in drinking water can help prevent tooth decay and improve oral health. The World Health Organization recommends drinking water containing a fluoride concentration of 0.5-1.5 mg/L, as this is effective in preventing dental cavities and being safe for consumption.

Benefits of Fluoride in Drinking Water

  • Fluoride helps to strengthen teeth and prevent tooth decay.
  • Fluoride in drinking water has been shown to reduce the incidence of dental cavities and improve oral health.
  • Fluoride has a positive impact on overall health.
  • Reduces risk of bone fractures (according to research)

Concerns about Fluoride in Drinking Water

  • Too much fluoride in drinking water can be harmful and cause fluorosis.
  • Fluorosis can lead to discoloration and damage to the teeth.
  • Possible Reduced IQ in children?
  • Possible Bone fractures?
  • PossibleThyroid problems?
  • The World Health Organization currently considers fluoride safe for consumption in recommended concentrations.

The Science Behind Fluoride Removal Process

The process of removing fluoride from drinking water involves the use of a filtration system that is specifically designed to remove fluoride. This can be accomplished through various methods, including reverse osmosis, activated alumina, and ion exchange.

Comparison of Fluoride Removal Methods

Reverse Osmosis: Reverse osmosis is a process that involves forcing water through a semipermeable membrane under high pressure. The membrane allows water molecules to pass through but filters out contaminants, including fluoride. Reverse osmosis is considered one of the most effective methods for removing fluoride from drinking water.

Activated Alumina: Activated alumina is a filter media specifically designed to remove fluoride from drinking water. Activated alumina works by adsorbing fluoride ions onto its surface, effectively removing them from the water.

Ion Exchange: Ion exchange is a process that involves exchanging ions in water with ions in a resin bed. In the case of fluoride removal, this process involves exchanging fluoride ions with hydroxide ions, effectively removing fluoride from the water.

Frequently asked questions (FAQ)


Whether you need to filter fluoride from your drinking water depends on several factors, such as the source of your water, the concentration of fluoride in your water, and your personal preferences. If your water source contains high levels of fluoride, filtering it may be necessary to avoid potential health risks associated with excessive fluoride intake. Some people may also choose to filter fluoride for personal or philosophical reasons. There are several types of water filters available, including activated carbon filters, reverse osmosis filters, and ion exchange filters, which can effectively remove fluoride from drinking water.

Comparing Brita and PUR filters is a matter of personal preference and specific filtration needs. Both brands offer a range of water filtration products, each with its own strengths and weaknesses.

Yes, some bottled water can contain fluoride. The amount of fluoride in bottled water can vary depending on the source of the water and whether it has been treated. Bottled water sourced from a public water supply is likely to contain the same level of fluoride as tap water. However, some bottled water brands market themselves as "fluoride-free" or "purified," which may indicate that they have undergone a filtration process that removes fluoride. It's best to check the label or contact the manufacturer for information on the fluoride content of specific bottled water brands.

My Experience & Expertise

As a dentist with years of experience, I have seen firsthand the impact fluoride can have on oral health. Fluoride is a naturally occurring mineral that is highly effective in reversing tooth decay and improving oral health.

In addition, water fluoridation has been a significant technological advancement, especially in underserved communities. Contact your public water supply if you have any questions or concerns about the fluoride levels in your drinking water.
