Myth: Activated Carbon Filters in Refrigerator or Pitcher Filters Can Reduce PFAS

Reality: Simple activated carbon filters, like those found in refrigerator filters or pitcher filters, are ineffective at removing PFAS compounds. Not only do these filters fail to make a significant impact on these persistent chemicals, but over time, they can also accumulate PFAS on their surfaces. As the carbon becomes saturated, it may start releasing these compounds back into the water, potentially increasing your exposure and making the problem worse.

Myth: Water Softeners Can Remove PFAS

Reality: Water softeners are designed to remove hardness minerals such as calcium and magnesium from water, but they do not have the capability to remove PFAS. Investing in a water softener will not address PFAS contamination in your water supply.

Myth: Bottled Water is a Safe Alternative

Reality: Bottled water is often not a safer option, as plastic bottles themselves can be a source of PFAS contamination. The chemicals used in manufacturing plastics can leach into the water, along with microplastics, leading to potential health risks. Additionally, bottled water companies are not always transparent about their water sources or purification processes.

Myth: Any Reverse Osmosis System Will Remove PFAS

Reality: While reverse osmosis (RO) systems can be effective at reducing PFAS, their efficacy depends on the quality of the system. Only RO systems with a 0.0001 micron membrane can effectively reduce PFAS to undetectable levels. However, relying solely on a point-of-use RO system without addressing the entire household water supply means you are still exposed to PFAS through showering and bathing. These chemicals can be absorbed through the skin, a process known as dermal absorption. Therefore, it is crucial to address PFAS contamination with a whole-house filtration system in addition to a high-quality RO system for drinking water.
