Biopure water generally refers to very highly purified water that meets strict cleanliness and purity standards beyond typical drinking water. In many technical uses, Biopure is a term associated with specialized systems and treatment processes designed to deliver water that is essentially free of bacteria, endotoxins (microbial toxins), and most dissolved impurities. This type of water is often used in medical, laboratory, or industrial settings where very high purity is required.
This water can is also very safe for consumption. The Purefecta® Guard specifically targets bacteria and viruses while meeting multiple WQA certifications.
Reverse osmosis filtration is often referred to as one of the most effective ways to reduce contaminants in your water, such as mercury, PFAS, total dissolved solids (TDS), and more. The FlexFilters offered with the K5 Drinking Water Station help to provide a wider, case-specific blanket of protection for your home's drinking water.
Filters like our Chloramine Guard are made specifically to target and reduce levels of chloramine that can be found in municipal water. Over 1/3 of the municipal water in the US is filtered using chloramine, meaning trace amounts are found more often than not. While it's not deadly, it can cause issues over time, especially if your water contains a significant amount.
The K5 Drinking Water Station can have our Mineral Plus filter added in tandem with our post filter. Reverse Osmosis filtration is sometimes considered "too strong", in that the process even reduces levels of "healthy" minerals that can naturally be found in our water. This filter is designed to add minerals such as magnesium and calcium back into the purified water, while keeping the same cleaner, more refreshing taste and high-quality.
