At Saalt, we’re committed to empowering you with knowledge—and premium products that support a healthier you and a healthier planet. Ready to ditch the uncertainty and put safe, sustainable period care first? Let’s get started.
What Are PFAS and Why They End Up in Period Products
PFAS, short for per- and polyfluoroalkyl substances, are a group of human-made chemicals found in everything from non-stick cookware to rain jackets. Often called “forever chemicals,” they don’t break down easily in the environment—or in our bodies. This persistence is what makes them both effective and problematic. Their chemical structure repels water, oil, and stains, so manufacturers use PFAS to make products more durable and leak resistant. (CNN)
When it comes to period products, PFAS can sneak in for similar reasons. Many manufacturers want to ensure tampons, pads, liners, and even some reusable products stay dry on the surface, hold their shape, and don’t absorb unwanted moisture too quickly. Sometimes, PFAS are intentionally added as part of a waterproof coating or finishing process. Other times, they end up in products unintentionally—maybe through contaminated water used in factories or from other treated materials handled on the same equipment.
The problem is, PFAS don’t just stay put. Minimal amounts can transfer from products right onto your skin or into your bloodstream with regular use. And growing research links PFAS exposure to several health concerns, like hormone disruption and increased cancer risks. That’s why there’s a growing movement to look for reusable period products made without PFAS and why savvy shoppers are learning how to spot these chemicals on product labels and brand transparency statements.

Health Risks Linked to PFAS Exposure
The popularity of PFAS-free menstrual cups is rooted in growing concerns around the health effects of PFAS chemicals. PFAS, or per- and polyfluoroalkyl substances, are synthetic compounds used in a huge range of consumer products for their stain-resistant, water-repellent, and non-stick properties. But what makes them so effective for manufacturers is exactly what makes them so risky for our bodies—they’re nicknamed “forever chemicals” because they stick around, both in the environment and in us. (Mayo Clinic)
When absorbed through the skin or mucous membranes, PFAS can accumulate in the body over time. Research has linked PFAS exposure to a range of potential health risks. Some of the most well-documented include:
· Hormone disruption: PFAS can mimic or interfere with natural hormones, influencing everything from reproductive health to metabolism. Scientists have found links between PFAS and irregular menstrual cycles, decreased fertility, and developmental delays.
· Immune system effects: Exposure to PFAS has been associated with decreased vaccine response and higher risk for infections, as these chemicals may weaken immune response.
· Increased risk of certain cancers: Studies have connected long-term PFAS exposure to certain cancers, including kidney and testicular cancer.
· Liver and kidney damage: PFAS is processed through the liver and can cause damage to both liver and kidney tissues over time, putting strain on the body’s natural filtration systems.
· Developmental and behavioral problems: For pregnant women, PFAS exposure may impact fetal growth and development, with recent research indicating possible links to low birth weight and learning delays in children.
Worse yet, PFAS aren’t quickly flushed from our systems. Their persistence means even low-level, repeated exposure—like what’s possible from products worn close to sensitive skin—can add up.
Switching to products made without PFAS, especially those that come into direct contact with sensitive mucous membranes, is one of the simplest and most effective ways to reduce your personal risk and contribute to a healthier environment for everyone. (EPA)
The Trouble With PFAS-Free Labels
When you’re on the hunt for a truly PFAS-free menstrual cup, you’ll quickly discover that not all “PFAS-free” labels are created equal. The trouble is, “PFAS-free” isn’t a regulated term, which means companies can use it in their marketing without any standardized testing or oversight. Shoppers might see those reassuring words and assume the cup is completely safe from any and all “forever chemicals”—but that’s not always the reality.
PFAS (per- and polyfluoroalkyl substances) are a class of chemicals linked to a laundry list of health concerns, and yet, their use in manufacturing can be sneaky. Materials like medical-grade silicone, often used to make menstrual cups, shouldn’t require PFAS for production. But contamination can still happen during manufacturing or processing, especially if facilities use PFAS-containing substances in finishes or other steps.
Some manufacturers rely on supplier assurances instead of independent testing. Others may only test for a handful of the thousands of possible PFAS compounds, leaving consumers with incomplete information. Packaging might proudly state “PFAS-free,” but unless those claims are backed by third-party testing—ideally, accessible to customers—it’s hard to know what you’re really getting.
For anyone trying to avoid unnecessary chemical exposure, this lack of transparency is a real headache. It’s important not to take claims at face value: look for brands that go the extra mile on testing, openly disclose their results, and are willing to answer questions about their processes. Because when it comes to what goes in your body, the details matter.
Materials to Look for in a Safe Menstrual Cup
When it comes to choosing a PFAS-free menstrual cup, the material is everything. Not only does it impact safety and comfort, but it also determines eco-friendliness and long-term durability. Here’s what you should have on your radar when browsing menstrual cup options:
1. Medical-Grade Silicone: This is the gold standard for menstrual cups. Medical-grade silicone is hypoallergenic, non-reactive, and free from harmful chemicals like BPA, latex, or phthalates. It’s also resistant to bacterial growth, making it a favorite for those seeking a cup that’s gentle on sensitive skin and easy to keep clean.
2. Thermoplastic Elastomer (TPE): Another safe choice, TPE is a flexible material that’s latex-free and less likely to cause allergic reactions. Some brands use TPE as an alternative to silicone, and it’s generally considered safe for use in medical products. As always, check that the TPE used is medical-grade—this ensures the highest standards.
3. 100% Latex-Free: Latex allergies are more common than you might think. To prevent irritation—or potentially severe reactions—make sure your menstrual cup is clearly labeled as latex-free.
4. No Added Dyes or Fragrances: Added coloring and fragrances can bring unnecessary risk. These additives sometimes contain chemicals that you just don’t want close to your most sensitive areas. Opt for cups that are transparent or naturally colored without synthetic dyes, scents, or gimmicks.
5. PFAS-Free Certification: Seek out brands that explicitly state their reusable period products are manufactured without PFAS and, ideally, provide third-party testing or certifications to verify this. PFAS chemicals aren’t always obvious, so a transparent materials policy and test results are your best bet.
6. Minimalist Ingredient Lists: The fewer ingredients, the better. Reliable menstrual cups don’t need a laundry list of additives—just a high-quality base material and the promise of purity from start to finish.
Choosing a menstrual cup made from trusted, body-safe materials lets you focus on comfort, sustainability, and peace of mind each cycle. Be sure to check product pages and FAQs for detailed materials info before making your decision.
Environmental Impact of PFAS vs Reusable Options
When it comes to sustainability, the difference between PFAS-laden products and reusable, PFAS-free options is night and day. PFAS, or polyfluoroalkyl substances, are often referred to as “forever chemicals” for a reason: they don’t easily break down in the environment. Instead, these substances accumulate in landfills and water systems, persisting for decades and impacting wildlife and human health alike. The environmental footprint of manufacturing and disposing of products containing PFAS is immense, contributing to water contamination and waste management crises worldwide.
In contrast, reusable menstrual products—when made from safe, PFAS-free materials—offer a dramatically lower environmental impact. Most menstrual cups, for example, can last up to a decade with proper care. That translates to hundreds, if not thousands, of disposable pads and tampons that never end up in a landfill. Choosing reusable menstrual products made without PFAS reduces not only your personal waste output but also your exposure to potentially hazardous chemicals. Plus, the emphasis on durable, medical-grade materials means these products are designed with both your body and the planet in mind.
By making the switch to sustainable, PFAS-free alternatives, you help limit the chemical load on both your body and the environment. Every small choice matters when it comes to protecting our water systems, our soil, and our collective future.
The Safer Choice is a Knowledgeable Choice
Choosing a PFAS-free menstrual cup is more than just a personal health decision—it's a powerful act that supports your well-being, the environment, and a more sustainable future. As research continues to shed light on the risks of PFAS and other forever chemicals, seeking out menstrual cups and period discs made from medical-grade silicone or other safe, non-toxic materials, and produced by transparent brands, empowers you and supports safer standards across the industry.

FAQs About Choosing a PFAS-Free Menstrual Cup
How can I tell if a menstrual cup is PFAS-free?
The best way to ensure your menstrual cup is PFAS-free is to check with the brand directly. The best menstrual disc and cup brands will be reputable and transparent about their manufacturing process and materials. Look for explicit statements on their website or packaging that say “made without PFAS.” You can also reach out to customer service for confirmation or request third-party testing results for extra peace of mind.
Are there specific materials to look for in a PFAS-free cup?
Yes! Look for menstrual cups and reusable menstrual discs made from 100% medical-grade silicone, natural rubber, or TPE (thermoplastic elastomer). These materials never require PFAS in their manufacturing or finishing processes. Steer clear of cups that list “proprietary materials” or don’t disclose their exact composition.
Why do some menstrual cups contain PFAS?
Some menstrual cup brands may use PFAS in finishing processes to give cups a slick or stain-resistant surface. PFAS can make products feel smoother or seem easier to clean, but these substances have raised health and environmental concerns due to their persistence in the human body and the environment.
Are there alternatives to menstrual cups that are guaranteed PFAS-free?
Absolutely! If you want to avoid PFAS completely, consider PFAS-free leakproof period underwear, like those made by Saalt, or pads and tampons from brands that specifically commit to PFAS-free materials and ethical manufacturing. Saalt’s reusable leakproof underwear is made without PFAs in the finishing process and is available in various absorbencies, sizes, and styles—perfect for all-life leaks, not just periods!
How do cleaning and sanitizing products affect PFAS in cups?
Standard cleaning and sanitizing don’t remove PFAS because they’re incredibly resistant to breaking down. If a cup contains PFAS, washing or boiling it won’t eliminate these chemicals. That’s why it’s so important to choose a cup that’s confirmed “made without PFAS” right from the start. Stick to gentle, non-toxic cleansers recommended by the cup manufacturer to prolong the life of your PFAS-free cup.
