PFAS in Lab Coats: Safe Workwear for Science Professionals

If you’re trying to cut PFAS out of your life, you’ve probably started with cookware and water filters. Lab coats? Probably not on your radar yet. But these man-made chemicals show up in consumer goods across dozens of categories, and workwear is one of them. The upside: switching to cleaner options is straightforward once you know what to look for.

What Does the Science Say About Lab Coats and PFAS?

Research published in Toxics (2022) found that PFAS exposure from everyday consumer products adds up in the body over time. Your liver and kidneys try to process these chemicals, but PFAS accumulate faster than they clear. Wearing a PFAS-free lab coat won’t solve everything on its own, but it removes one more source from your daily total.

Many lab coats use durable water repellent (DWR) coatings or stain-resistant finishes that rely on PFAS chemistry. These treatments help lab coats shed liquids and resist stains, but they also expose the wearer to fluorinated compounds through skin contact and off-gassing over time.

What to Look for When Shopping for Lab Coats

Labels won’t always tell you what’s in your lab coat. Most manufacturers aren’t required to disclose PFAS use. A few things that help:

Third-party certifications like OEKO-TEX Standard 100 or bluesign explicitly restrict PFAS. If a lab coat is described as “water-repellent” or “stain-guard,” ask the manufacturer whether they use a fluorine-free treatment before buying. The PFAS Free Life Database keeps an updated list of verified clean products if you want to skip the detective work.

The simplest option? Untreated 100% cotton. It’s breathable, comfortable for long shifts, and free from fluorinated coatings by default.

Top PFAS-Free Lab Coat Options to Try

When shopping, look for 100% cotton construction without water-repellent or stain-resistant treatments, and check for OEKO-TEX Standard 100 certification if available. Here are two options worth considering:

Professional Unisex 100% Cotton Lab Coat - A midweight cotton lab coat with multiple pockets and snap closures, made from 100% cotton with no chemical coatings.

Bulwark Flame Resistant 7oz Cotton Lab Coat - A heavier-duty option in 100% cotton for professionals who need flame resistance without relying on PFAS-based treatments.

Practical Steps to Minimize Exposure from Lab Coats

You don’t have to overhaul everything at once. Start with the biggest exposure sources (cookware, water, food packaging) and work outward. For lab coats:

• Replace products with fluorine-based coatings as they wear out, rather than all at once
• Choose 100% cotton lab coats without “water-repellent” or “stain-guard” labeling
• Wash new lab coats before first use to reduce surface chemical loads
• Use our guide to PFAS free food storage bags for the kitchen
• Check cookware safety in our PFAS free cookware guide

It takes time to swap everything out, but each change counts. The PFAS Free Life Database can help you figure out what to tackle next.

Frequently Asked Questions

How do I know if my lab coat has PFAS?

Without laboratory testing, it can be difficult to know for certain. Watch for marketing terms like ‘water-repellent,’ ‘stain-guard,’ ‘grease-resistant,’ or ‘wrinkle-free’ which often signal PFAS treatments. Look for certifications like OEKO-TEX Standard 100 or bluesign that prohibit PFAS. You can also search the PFAS Free Life Database at database.pfasfreelife.com for verified clean products.

Can I test my home for PFAS contamination?

Yes. You can test your drinking water for PFAS using certified laboratory testing services or at-home kits from companies like SimpleLab. For other types of exposure, from products or household dust, testing is more complex, but starting with your water is the most impactful first step. Your state health department may also offer resources or low-cost testing programs.

Do all lab coats contain PFAS?

No, not all lab coats contain PFAS. However, many products that are marketed as water-resistant, stain-resistant, or non-stick have historically used PFAS-based treatments. The safest approach is to look for 100% cotton lab coats without chemical finishes, or to contact the manufacturer directly to ask about their chemical policy.
