The Perchlorate Guard cartridge significantly reduces perchlorate in water. Perchlorate is a byproduct of certain forms of manufacturing, but it can also occur naturally.
Special Notice: Replacement cartridges purchased online (Amazon or other retailers) are not approved or certified for use with Kinetico products, may not perform to specifications, and their use will void your product warranty.

According to the EPA, perchlorate is commonly used in solid rocket propellants, munitions, fireworks, airbag initiators for vehicles, matches, and signal flares. Perchlorate may occur naturally, particularly in arid regions such as the southwestern United States, and is found as an impurity in hypochlorite solutions used for drinking water treatment and in nitrate salts used to produce nitrate fertilizers, explosives, and other products.
New studies show that perchlorate has also now contaminated irrigation water, fertilizer, and food. Perchlorate is detectable in nearly all produce, dairy products, and packaged foods, accounting for an estimated 80 percent of Americans' exposure.
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.
