PFAS Symptoms in Humans and How to Avoid Them?

Introduction

PFAS, or per- and polyfluoroalkyl substances, are a large group of human-made chemicals used for their water- and grease-resistant properties. Commonly found in non-stick cookware, food packaging, stain repellents, and firefighting foams, PFAS are often called “forever chemicals” because they don’t break down easily in the environment or the human body.

Due to their persistence, PFAS accumulate over time—posing serious concerns for public health and drinking water safety.

How Do PFAS Affect Human Health?

You may be wondering: how do PFAS affect human health?

Extensive studies have shown that exposure to PFAS can disrupt several biological systems. Some of the most well-documented PFAS health impacts include:

• Immune system suppression: Reduced response to vaccines and increased susceptibility to infections.
  

• Hormonal interference: Disruption to thyroid and reproductive hormones.
  

• Liver damage: Elevated liver enzymes and potential liver function abnormalities.
  

• Increased cholesterol levels: Even at low levels of exposure.
  

• Cancer risk: Certain types of PFAS are linked to kidney and testicular cancer.
  

As research continues, our understanding of PFAS effects on human health is becoming clearer—and more concerning.

Common PFAS-Related Health Symptoms

Although PFAS exposure doesn’t always cause immediate symptoms, long-term contact may lead to:

• Thyroid disorders such as hypothyroidism
  

• Developmental delays in infants exposed in utero
  

• Fertility issues in both women and men
  

• Weight gain or metabolic changes 
  

• Immune-related conditions, like frequent colds or reduced vaccine response
  

• High cholesterol or liver function issues
  

Understanding these symptoms helps you identify if you may have been exposed—and why it’s important to act.

PFAS in Water: Health Effects

Contaminated drinking water is one of the most common ways people come into contact with PFAS. Communities near industrial sites or airports are especially vulnerable.

So, what are the PFAS in water health effects?

They can include:

• Kidney and liver stress from long-term ingestion
  

• Suppressed immune responses
  

• Potential developmental issues in children
  

• Elevated risk of some cancers
  

Because PFAS are odourless and tasteless, regular water testing is the only reliable way to detect them.

Best Water Filters for PFAS Removal

To protect your household, the best water filter for PFAS is one that’s been independently tested and proven to remove these chemicals effectively. Top choices include:

• Reverse Osmosis (RO) Systems – Use a semi-permeable membrane to remove up to 99% of PFAS
  

• Activated Carbon Filters (GAC) – Adsorb and trap PFAS molecules, effective for many households
  

• Ion Exchange Filters – Replace PFAS ions with safer alternatives
  

Genzon Water offers purification systems that combine these advanced technologies, giving you clean, PFAS-free water straight from your tap.

How to Avoid PFAS Exposure

Besides filtering your water, there are lifestyle choices that can help you steer clear of PFAS:

• Avoid non-stick cookware (especially older ones with PFOA-based coatings)
  

• Read product labels and choose PFAS-free alternatives in cosmetics, food packaging, and clothing
  

• Reduce fast food intake, as packaging often contains PFAS
  

• Stay informed about PFAS testing and reports in your local area
  

Avoiding PFAS entirely can be challenging—but small, consistent actions can significantly reduce your exposure.

Conclusion

PFAS are invisible but potentially dangerous chemicals that have made their way into many aspects of our lives—from the water we drink to the products we use daily. Understanding what the health effects of PFAS are and how to minimise exposure is essential for protecting your wellbeing.

By investing in reliable water filtration (like those from Genzon Water) and making more conscious consumer choices, you can take proactive steps to safeguard your health from the harmful impacts of PFAS.
