You can’t see them. You can’t smell them. But PFAS — the “forever chemicals” — are increasingly turning up in water supplies across the country.
Linked to serious health risks like cancer, immune disruption, and developmental issues, these stubborn contaminants are notoriously difficult to remove once they’re in the environment.
The good news?
With the right water treatment strategy, you can dramatically cut your PFAS exposure starting today. 🚿
Here’s how to do it — and what filters actually work.
🧠 Quick Takeaways:
- ✅ Standard water filters (like basic pitchers) aren’t enough to tackle forever chemicals.
- ✅ Reverse osmosis systems and activated carbon filtration are two of the strongest defenses.
- ✅ Ion exchange filters also help — but only with the right resin type.
- ✅ Distillation can remove stubborn contaminants, but it’s slow and better for small batches.
- ✅ Certified filtration systems offer the best protection for your drinking water at home.
- ✅ Testing your water is the only way to confirm contamination — you can’t taste or smell it.
💡 What Are PFAS — and How Do They End Up in Water?
PFAS-based chemicals have quietly made their way into everyday life since the mid-20th century — showing up in everything from food packaging to firefighting foam.
- 🛍️ Fast-food wrappers and packaging
- 🔎 Non-stick cookware (like Teflon)
- 👕 Water- and stain-resistant clothing
- 🎨 Paints and surface sealants
- 🧴 Cosmetics, lotions, nail polish
- 🧯 Firefighting foam used at airports and industrial sites
But these compounds don’t break down easily — earning them the nickname “forever chemicals.”
When tossed out, burned, or washed down drains, they can migrate into soil, rivers, and drinking water aquifers.
Once they’re out in the environment, these chemicals don’t just disappear — they gradually leach into rivers, soil, and eventually, your drinking water.
⚠️ Are These Chemicals Dangerous to Your Health?
Some of the most studied compounds in this family — like PFOA and PFOS — have been found in the blood of people across the globe. Even at trace levels — health experts are raising concerns.
According to the Environmental Working Group (EWG), long-term exposure has been linked to:
- 🧬 Increased risk of cancer (kidney, liver, testicular)
- 👶 Low birth weight and developmental delays
- 🦠 Immune system dysfunction
- 🧠 Hormonal disruption and thyroid issues
- ⚖️ Potential links to weight gain and fertility problems
And yet, there’s still no federally enforceable legal limit under the Safe Drinking Water Act.
🏛️ Is the EPA Doing Anything About It?
The EPA classifies these as emerging contaminants — meaning they’re under review but not yet subject to strict federal regulation.
At the moment, there’s only a non-enforceable health advisory of 70 parts per trillion for a few of the better-known compounds (PFOA and PFOS). Many health experts say that’s not low enough to be protective.
States like California and Maine have taken matters into their own hands by banning certain products and setting much stricter limits.
But without consistent nationwide action, it’s often up to individual households to manage the risk.
🧪 How to Tell If These Chemicals Are in Your Water
You can’t see, smell, or taste PFAS — which makes them especially tricky. And while the EPA and local utilities have begun testing, many systems still don’t screen for them regularly.
If you’re on a private well, testing is entirely up to you.
That’s why lab testing is the only way to know for sure.
We recommend SimpleLab’s Tap Score PFAS test — it screens for 14 common compounds down to 2 parts per trillion (ppt). We really love Tap Score and you will too : )
| 🧪 Test Type | 🔍 What It Does | 💡 Good To Know |
|---|---|---|
| 🧪 Tap Score (Lab Mail-In) | Tests for 14+ PFAS with high accuracy (down to 2 ppt) | Best all-around option for homeowners — includes prepaid shipping & instructions |
| 🏛️ Local Lab Testing | Professional-grade results based on EPA Method 537 | Great if you prefer a local lab — may cost more or require in-person dropoff |
| 🧾 City Water Quality Reports | Some municipal utilities include PFAS data in annual reports | Useful for baseline awareness, but not updated frequently or site-specific |
| 🚫 DIY Test Strips | No PFAS-specific test strips are available yet | Avoid DIY kits — they don’t offer reliable results for these chemicals |
🧠 Pro Tip: Avoid wearing waterproof or stain-resistant clothing when collecting your sample — even your gear can shed trace chemicals that skew results.
🚰 Which Filtration Methods Actually Work?
There’s a lot of hype out there about what removes these chemicals, but only a few filter types actually get the job done. Here’s how the most effective systems compare — and where each one fits best in a home setup. 👇
| ⚙️ System Type | ✅ Removes PFAS? | 💬 What To Know |
|---|---|---|
| 🟤 Activated Carbon | Yes (up to 99%) | Great for chlorine & taste too — just keep filters changed regularly |
| 💧 Reverse Osmosis | Yes (90–99%) | Best for drinking water — excellent all-around contaminant removal |
| 🔄 Ion Exchange | Yes (with anion resin) | Targets specific PFAS but doesn’t remove chlorine — often used for well water |
| 🔥 Water Distillers | Yes | Affordable & effective but slow — best for small daily drinking water needs |
💡 Good to Know: Reverse osmosis and activated carbon are the most reliable choices for households dealing with a wide range of tap water contaminants — not just PFAS. For more guidance, here’s a closer look at water filters designed to remove PFAS.
🏡 Do You Need a Whole-House Filter or Just One Faucet?
When it comes to forever chemicals, you don’t necessarily need to filter every drop of water entering your home. It depends on where you’re most concerned about exposure.
Here’s a quick breakdown to help you choose the right setup: 👇
| 🚰 Filter Type | 📍 Where It Works | 💡 Pros and Cons |
|---|---|---|
| 🛁 Whole-House Systems | Treats water before it reaches any faucet, shower, or appliance | ✔️ Good for general chemical reduction ❌ Costlier upfront, not always necessary for PFAS |
| 🚿 Point-of-Use Filters | Targets a single location (kitchen sink, fridge dispenser) | ✔️ Best for drinking and cooking water ✔️ Lower cost, easier install ❌ Doesn’t protect shower water (not critical for PFAS) |
💬 Helpful Tip: Research shows PFAS aren’t absorbed through the skin easily — so focusing your budget on filtering what you drink and cook with gives the biggest return on investment💧
🔎 Choosing the Best System for Your Home
Not all filtration systems are created equal — especially when it comes to stubborn contaminants like forever chemicals.
Here are a few key things to think about before you invest: 👇
- ✅ Contaminants Removed: Make sure the filter specifically lists PFAS or PFOA/PFOS reduction — not just “improves taste.”
- ✅ System Capacity: Pick a size that matches your family’s water use. Tiny pitchers won’t cut it for large households.
- ✅ Filter Replacement Costs: Look beyond the sticker price — maintenance adds up over time. Check how often filters need to be replaced.
- ✅ Certification Matters: NSF-certified filters are independently tested to meet real safety and performance standards.
- ✅ Wastewater and Energy Use: Reverse osmosis systems waste some water. Distillers use more electricity. Make sure you factor operating costs into your decision.
💬 Smart Move: It’s usually better to slightly over-size your filter system than risk buying one that clogs or wears out too quickly — especially when it comes to protecting your family’s health long-term.
💭 Final Thoughts: Small Steps, Big Impact
There’s still a lot we don’t know about forever chemicals — but what we do know is that filtration makes a difference.
Start by testing your water. Then choose a filter that fits your needs and your home.
✅ Even small changes can reduce exposure and help you feel better about every sip, every shower, and every load of laundry.
Clean water doesn’t have to be complicated — and peace of mind starts with one smart step. 💧
