Years ago after I started reading the research on PFAS and phthalates, I made a list of every potential exposure in my kitchen and felt mildly horrified. The pans, the plastic storage containers, the candles, the cling wrap, the fragrance in the dish soap...all of these carry potential health hazards.

The instinct, when you read enough of this research, is to throw everything out and start over, but that isn't necessary.

I have spent the last few years swapping things out gradually and I want to share what I decided actually mattered based on the research, what didn’t and where I think most “clean kitchen” advice goes off the rails.

WHAT THE RESEARCH ACTUALLY SHOWS

The two main villains in your kitchen are PFAS (the chemicals that make nonstick coatings nonstick) and phthalates (plastic softeners that leach into food). Both are well-documented endocrine disruptors. The most recent research on phthalates alone connects global exposure to roughly two million preterm births and tens of thousands of neonatal deaths each year. PFAS, the so-called “forever chemicals,” persist in your body for years and have been linked to thyroid disease, immune effects and certain cancers.

This is not fringe science. The exposure is real, even though some will say the amount in this product or that one isn't enough to matter. The problem is, we are exposed to hundreds of products each day that contain these chemicals.

However, not every product you replace will move the needle much. Some swaps are high-impact. Others are vanity swaps that make you feel virtuous and don’t actually reduce your body burden in any measurable way.

THE SWAPS THAT MATTERED MOST

1. Replacing my old nonstick pans. This was the highest-impact change I made. Since I work from home, I cook and eat almost every meal made from the pans in my kitchen. Scratched, flaking nonstick is the worst PFAS exposure most people have in their kitchen. I replaced mine with a mix of stainless steel, cast iron and a couple of PFAS-free ceramic-coated pans for eggs. The full breakdown is in my guide to PFAS-free cookware.
2. Switching air fryers. I lived with a coated air fryer for years before I really looked at what was inside it. I just published my non-toxic air fryer guide with what I tested and what I now use. This is one of the more important ones since higher heat means more PFAS released into your food.
3. Replacing plastic food storage with glass. Phthalates leach most when fat or heat is involved. Storing leftovers in glass instead of plastic, especially anything you reheat, was probably the single biggest reduction in my overall exposure. It is also the cheapest swap on this list. I tried several different brands before settling on Ziruma, you can learn why I chose that one in my full review.
4. Candles and air fresheners release phthalates too, plus some candles also release lead into the air. This is one of the least fun ones I've given up because stores like Home Goods are full of creative looking and delicious smelling candles I'd love to buy! Unfortunately, knowing what I know now, I've slowly transitioned to clean brands for these as well, more on that in a future HNG article.
5. Mugs. I just recently learned about this one and it's even more depressing than the candles. I have such a fun coffee mug collection but unfortunately, most of them are likely full of lead too.

WHAT I DID NOT BOTHER WITH

I did not throw out my enameled cast iron. The research on those is more nuanced than the alarmist headlines suggest and the brand and condition matter more than the category. After doing the research on that, it turns out enameled cast iron is actually very safe.

I did not chase every “non-toxic” label I saw. A lot of those certifications are marketing.

WHERE I SHOP NOW

The biggest practical problem with going PFAS-free and phthalate-free is sourcing. Most grocery and big-box stores don’t make this easy and the labeling is opaque enough that you can spend an hour reading the back of a cleaning bottle and still not know what you’re getting.

Trulyfree is what I have been using to make this easier on myself. I have been using their cleaners and laundry products for over six years and when they started this marketplace I was really excited. They vet every product for PFAS, phthalates and other endocrine disruptors, so the work is already done. You can browse my curated picks here. Laundry, cleaning, food storage and kitchen tools, all in one place.

GO DEEPER

If you want the research foundation, my pillar on what PFAS are walks through the full picture (with the research of course) and phthalates in food covers the dietary side.

I encourage you to pick one swap this week and let momentum carry you to the next one. You don't need to replace everything all at once but anytime you do need something new in your kitchen, it's well worth looking into the materials.
