Are You Drinking Tiny Plastic Bits? How to Filter the Invisible Pollutants PFAs in Your Tap Water

Your tap water maybe full of tiny plastic particles. 

Recent studies have revealed a growing concern that microplastics and PFAs (per- and polyfluoroalkyl substances) are increasingly being found in water supplies worldwide. These microscopic invaders are resilient, impossible to break down, and can accumulate in the human body over time. 

Potential health effects range from hormonal disruptions to negative impacts on our immune system. 

What Are Microplastics and PFAs?

Microplastics are tiny plastic fragments, smaller than 5 millimeters, that come from degraded plastic bottles, packaging, synthetic fabrics, and even car tired. Every time something plastic breaks down, rainwater can carry these fragments to rivers, reservoirs, and eventually your home's water supply. 

PFAs (per- and polyfluoroalkyl substances) are often referred to as "forever chemicals". These groups of man-made compounds are used in everyday products like non-stick cookware, water proof clothing, firefighting foam, and food packaging. These substances are designed to resist heat and water. When PFAs enter groundwater, PFAs linger for many decades because they do not naturally break down. 

Microplastics and PFAs form an invisible cocktails of contaminants that are impossible to remove without proper filtration. 

Health Risks of Microplastics and PFAs

  • Hormonal disruptions: PFAs mimic natural hormones in the body, leading to possible endocrine system interference.

  • Immune system effects: Studies have linked PFA exposure to weakened immune responses and vaccine resistance.

  • Developmental and reproductive concerns: Long-term exposure may affect fertility and child development.

  • Microplastics accumulation: These small particles can enter the bloodstream and potentially cause inflammation or cellular damage.

In short, the longer these substances remain in your water supply, the greater the risk to your health.

How to Effectively Filter Microplastics and PFAs

The good news is that you can effectively remove microplastics and PFAs from your drinking water with the right filtration technologies. Not all filters are capable of handling these contaminants, but advanced systems from Express Water use multi-stage filtration processes that target them precisely.

Reverse Osmosis (RO) Filtration

Reverse osmosis is one of the most effective methods for removing PFAs and microplastics. Using a semipermeable membrane, an RO system pushes water through microscopic pores that trap contaminants as small as 0.0001 microns. These membranes are small enough to block even the tiniest plastic particle and dissolved chemical. 

Activated Carbon Filtration

Activated carbon filters are another essential line of defense against microplastics. The filters use an absorption process to bind contaminants to the surface of carbon particles. 

Express Water Reverse Osmosis System

Express Water Comprehensive system combines multiple filtration stages to remove up to 99% of contaminants. Express Water Systems are one of the best solutions for microplastic and PFA removal, ensuring every drop of water that reaches your glass is safe and clean.
