Introduction: A Personal Mission for Clean Water
For nearly two decades, I've dedicated my career to developing products that not only push boundaries on performance, design, and user-friendliness but also the simplicity that promotes its core focus and what the product is supposed to deliver. When I embarked on the journey into water filtration, I quickly realized this was more than just another product challenge—a mission centered around our most essential resource: water.
Despite water's fundamental role in our lives, many know surprisingly little about its quality and the contaminants that can compromise it. Developing a product that purifies water, I needed to learn about the science of water, what is good water, and what contaminants we are cleaning out. Among the most concerning threats are PFAS substances—a complex chemical class that has infiltrated water supplies worldwide. Before offering a solution, it's essential to understand what it is and how to remove it. PFAS is a fundamental threat to our drinking water and should be handled with understanding and transparency. At Vitaloop, we recognized that tackling such invisible dangers required a fresh, sophisticated approach to filtration that goes beyond conventional solutions. Here's how we're making a difference.
What is PFAS? Decoding the Complex Contaminants
PFAS, or per- and poly-fluoroalkyl substances, are a large family of synthetic chemicals used since the 1940s in various industrial and consumer products, including non-stick cookware, water-resistant fabrics, firefighting foams, and even some cosmetics. They're often referred to as "forever chemicals" because of their strong carbon-fluorine bonds, which make them extremely resistant to environmental and human degradation.
Facts About PFAS:
- Complex Composition: PFAS consists of thousands of compounds, broadly categorized into long-chain and short-chain PFAS, each with different properties and health implications.
- Persistent and Pervasive: These chemicals have been found in the blood of 95% of Americans, indicating widespread exposure.
-
Sources of Contamination: Industrial discharges, the use of firefighting foams at military bases and airports, and leaching from landfills are common ways PFAS enter water supplies.
Understanding PFAS Complexity: Short-Chain vs. Long-Chain Compounds
PFAS are not a uniform group; they vary in chain length:
- Long-Chain PFAS: This includes PFOA and PFOS, which were historically used and are now regulated due to their bioaccumulative nature and toxicity.
Important: These are not easy to remove, but they are easier to remove as they are larger particles. Most water filtration companies refer to this when they say they remove PFAS. Please note that claimed efficiency is a lab report and not the same when the product is used in real life.
- Short-Chain PFAS: Developed as alternatives to long-chain PFAS, such as GenX chemicals and PFBS. While they break down slightly faster, they are still persistent and can be more difficult to remove from water due to their smaller size.
Vitaloop FlexGuard water filtration bottle removes Long-Chain PFAS with 98.5% efficiency from any water source. Control of time is a critical variable to ensure we stand by this claim, and since we have an automated pump, we can deliver on it anytime.
What Are the Different Types of PFAS?
PFAS encompass a vast family of over 12,000 chemicals, characterized by their strong carbon-fluorine bonds. They are broadly categorized based on their chemical structures and uses. Here are some of the most significant PFAS compounds:
-
Long-Chain PFAS:
- Perfluorooctanoic Acid (PFOA):
- Uses: Previously used in the production of Teflon for non-stick cookware, stain-resistant fabrics, and firefighting foams.
- Status: Phased out in the U.S. but still persists in the environment.
- Perfluorooctane Sulfonate (PFOS):
- Uses: Formerly used in Scotchgard fabric protectors and firefighting foams.
- Status: Production voluntarily phased out by manufacturers in the U.S.
- Perfluorooctanoic Acid (PFOA):
-
Short-Chain PFAS:
- Perfluorononanoic Acid (PFNA):
- Uses: Utilized in plastics and surfactants, often as a processing aid in the manufacture of fluoropolymers.
- Perfluorohexane Sulfonic Acid (PFHxS):
- Uses: Found in firefighting foams and in water-repellent fabrics.
- Perfluorobutanesulfonic Acid (PFBS):
- Uses: A replacement for PFOS in various applications, including stain-resistant textiles and fire extinguishers.
- Hexafluoropropylene Oxide Dimer Acid (GenX Chemicals):
- Uses: Developed as a replacement for PFOA in the production of fluoropolymers like Teflon.
- Perfluorohexanoic Acid (PFHxA):
-
Uses: A degradation product of other PFAS; used in manufacturing fluorotelomers for stain-resistant fabrics.
-
Uses: A degradation product of other PFAS; used in manufacturing fluorotelomers for stain-resistant fabrics.
- Perfluorononanoic Acid (PFNA):
Implications
The diversity of PFAS compounds requires advanced filtration technologies capable of targeting both long-chain and short-chain PFAS. Vitaloop has a solution like no other in the water filtration space. Reverse Osmosis can remove them, too, but that has other negative implications, such as eliminating minerals and leaving you with unhealthful water. If you choose this method, you need to reenter minerals. Please note that this filtration solution is expensive and energy-inefficient. [Read more on Reverse Osmosis].
