How Whole-House Filtration Blocks Both PFAs and Microplastic Build-Up

Clean Water flows through every pipe, showerhead, appliance, and faucet in your home.

But how safe is your water?

Your home's water maybe contaminated with PFAs (per- and polyfluoroalkyl substances) and microplastics.

One of the most comprehensive ways to protect your family is using a whole house filtration system. This type of filtration system filters all water entering your home at the water source.

Understanding Whole-House Filtration

Whole house filtration systems are "point-of-entry" systems that filters your water before the water flows through your home's pipes and fixtures. This if beneficial to your home because it prevents hard unfiltered water from scaling and clogging your home's water sensitive systems.

Point-of-use filters, such as countertops or under-sink units, purify water from a single source. Whole house systems offer broader protection ensuring that water used for drinking, cooking, bathing, and cleaning.

Whole House advantages include:

Comprehensive coverage: Every water outlet in your home delivers filtered water.
Convenience: Once installed, these systems work automatically with minimal maintenance.
Plumbing and appliance protection: Filtered water helps prevent scale, sediment, and chemical buildup, extending the life of household fixtures.

The Problem with PFAs and Microplastics

What Are PFAs?

PFAs, or “forever chemicals,” are a group of synthetic compounds used in non-stick cookware, firefighting foam, stain-resistant fabrics, and more. These chemicals are extremely persistent and do not break down easily. As a result, PFAs contaminate soil, ground water, and municipal water systems worldwide.

Exposure to PFAs has been linked to several health risks, including:

Hormonal imbalances and thyroid disruption
Immune system suppression
Liver damage
Increased risk of certain cancers

What Are Microplastics?

Microplastics are tiny plastic particles, less than 5 millimeters in size, that come from degraded plastic waste, synthetic clothing fibers, and industrial runoff. They can infiltrate water supplies through environmental pollution or aging infrastructure.

Although research is ongoing, studies suggest microplastics may carry toxins, disrupt endocrine systems, and cause inflammation when ingested or absorbed through the skin.

Because both PFAs and microplastics are small and resilient, they can easily pass through standard water treatment systems. That’s why removing them at the household level is crucial and an Express Water whole-house filtration system provides some of the most reliable defense.

How Whole-House Filtration Systems Work

Whole-house filtration systems use multi-stage purification technology to target different types of contaminants. Each stage plays a vital role in capturing PFAs, microplastics, and other pollutants that compromise water safety. Below are some possible filtration stages for your particular Express Water Whole House Filtration System.

Sediment Filtration

The first stage typically uses a sediment filter to trap large particles such as sand, rust, and silt. This helps protect the finer filtration stages that follow while improving overall water clarity.

Activated Carbon Filtration

Activated carbon filters are essential for removing PFAs and other organic compounds. The porous carbon material adsorbs harmful chemicals, odors, and chlorine, preventing them from entering your household water. Studies show that granular activated carbon (GAC) is particularly effective in reducing PFAs to safe levels.

Advanced Filtration Layers

Some systems incorporate Kinetic Degradation Fluxion (KDF) or catalytic carbon to target heavy metals and enhance chemical removal. These layers also help control bacteria and prevent scale buildup inside plumbing.

Optional Reverse Osmosis or Specialized Filters

For homeowners seeking the highest level of purification, some systems include reverse osmosis membranes or additional cartridges that can filter out microscopic contaminants including microplastics smaller than one micron.

Benefits of Whole-House Filtration

Comprehensive Home Protection
You’ll enjoy purified water for drinking, bathing, cooking, and cleaning — ensuring your family is protected from PFAs and microplastics in all forms of use.

Healthier Skin and Hair
Removing harsh chemicals and microplastics prevents irritation and dryness, especially for sensitive skin.

Longer Appliance Life
Clean water prevents mineral and chemical deposits in water heaters, dishwashers, and washing machines, reducing maintenance costs and extending product lifespan.

Better Taste and Odor
Filtration eliminates chlorine, sulfur, and other unpleasant tastes or smells, improving the overall quality of your household water.
