The Best Non-Toxic Living Swaps I've Actually Made

I’ve gradually become much more aware of what I’m exposed to every day. The more I wrote about health and longevity, and the more I saw around microplastics, PFAS, endocrine disruptors and so-called "non-toxic" living, the more I wanted to understand which everyday exposures were actually worth reducing.

That curiosity hasn't resulted in a complete overhaul of my home. My kitchen still contains plastic, I haven't replaced every beauty product I own and I'm not interested in analysing everything that comes through the front door. Food might be the exception. I already read ingredient lists and I'm trying to eat fewer ultra-processed foods, but that's a separate rabbit hole.

Instead, I wanted to know which of these everyday exposures were actually worth doing something about. The water I drink. The pan I cook with. The containers I store and reheat leftovers in. The deodorant I apply every morning. The products I use during my period. I use them frequently, often for years at a time, which made me curious about what repeated exposure could actually mean for health.

"Non-toxic" is the phrase usually attached to these swaps, although respiratory physiologist, pharmacologist, and science communicator, Dr. Nneka Irechukwu, PhD, says that's not really how toxicology works. "'Non-toxic' is one of those terms that's become incredibly popular, but from a scientific perspective it isn't a recognised category," she explains.

A substance's potential effect on health depends on the substance itself and the exposure. Certain chemicals can interfere with hormone signalling, affect cellular processes or cause toxicity in particular organs at sufficient doses, while others pose little concern at the levels we're typically exposed to. How much you're exposed to, whether you ingest, inhale or absorb it through the skin, how often that happens and your individual biology all influence the risk.

Tamsin Lewis, MD, MRCPsych, a longevity doctor and lifestyle medicine specialist, uses that same exposure-led thinking to decide which changes are actually worth making. Certain chemicals found in plastics, furnishings, food packaging and household dust can enter the body, and some compounds have been studied for their effects on hormonal, metabolic and inflammatory pathways. Their presence in our environment doesn't mean they're causing us harm. Exposure level, frequency and route all influence what that presence means for health. Her approach is to reduce chemical load over time, prioritising exposures backed by reasonable evidence where the change is practical, rather than treating every synthetic material as a threat.

"Natural" isn't a reliable shorthand for healthy or safe either. Arsenic and certain mould toxins occur naturally and can be seriously harmful, while a long list of synthetic substances, including the paracetamol in your cupboard, are used safely every day. Where something comes from tells you very little about its potential effect on health. Dose, exposure route and frequency help determine risk.

That gave me a much better filter for deciding what deserved changing. Dr. Irechukwu asks six questions: how frequently do I use it, am I eating it, inhaling it or applying it to my skin, how long does that contact last, is heat involved, is the product old or damaged, and what does the research actually show?

Those questions became the filter for my own swaps too. Here's what made the cut.

1. I started filtering the water I drink

The swap: LARQ PureVis Self-Cleaning and Purifying Water Pitcher

Water was an obvious place to start because it's probably my most consistent exposure. UK tap water is safe and closely regulated, so I wasn't trying to fix a dangerous supply. I just wanted an extra layer of filtration for trace substances that can remain after treatment, including certain PFAS (per- and polyfluoroalkyl substances). I've also stopped regularly buying bottled water and carrying a stainless-steel bottle instead, reducing how often my drinking water sits in single-use plastic.

Why: "Water is one of the few things we consume several times a day, every day, for our entire lives," says Dr. Irechukwu. Depending on the technology, filters can reduce chlorine, some organic compounds, and contaminants including certain PFAS, a group of chemicals research has associated with reproductive, developmental, and metabolic effects when exposure is repeated over time. Drinking water is only one possible source, and detecting a trace amount doesn't mean it's causing harm. 

I chose LARQ because its Nano Zero filter is independently tested against recognised NSF/ANSI standards, so the claims are verified rather than taken on trust. It also uses UV-C light to keep the reservoir clean between fills.

What to look for: independent certification (NSF/ANSI or WQA) for the specific contaminants you care about, not just words like "pure" on the box. If you're also cutting back on bottled water, stainless steel or glass keeps it consistent rather than swapping one type of plastic contact for another.

2. I started filtering my shower water too

The swap: Hello Klean Shower Head Filter

Since I was already filtering the water I drink, I started thinking about the water I shower in too. I live in a hard-water area and assumed a shower filter would soften it. It turns out, it won't. A proper water softener is a whole different system. What a showerhead filter can do is reduce the chlorine I'm exposed to every time I shower.

Why: During a hot shower, some chlorine can enter the air you're breathing. Dr. Irechukwu is clear that inhaled chlorine acts as a respiratory irritant, which gave me a far more concrete reason to filter than just wanting "cleaner" water. She recommends looking for KDF-55, a filtration material built to neutralise free chlorine in hot, high-pressure water. Hello Klean combines KDF-55 for chlorine-reduction with activated carbon and amino acid granules, and the brand states it reduces more than 90% of chlorine and heavy metals.

What to look for: KDF-55 in the filter media, and a stated reduction percentage for chlorine specifically, not just a general purifying claim.

3. I replaced my scratched non-stick pan

The swap: Caraway Non-Stick Ceramic Sauté Pan

My old frying pan was the clearest candidate for replacement. I used it constantly, often at high heat and, after years of wear, the non-stick coating was visibly scratched.

Why: Most traditional non-stick pans get their slip from PTFE. Dr. Irechukwu is clear that an intact PTFE coating, used as instructed, is considered safe. The concern increases when coatings become old, scratched, or damaged, or when an empty pan is left over very high heat, as PTFE can begin to degrade and release fumes. That was reason enough for me to retire mine.

I chose Caraway's sauté pan, which uses a mineral-based ceramic coating made without PTFE, PFOA, PFAS, lead, or cadmium. The aluminium core still heats quickly and evenly, so practically, I haven't lost what I liked about non-stick cookware.

What to look for: start by checking the condition of the pans you already own. Scratching, flaking, or significant visible damage is a sensible cue to replace coated cookware. If you're switching materials, check what the new coating is actually made from as well as what the brand says it doesn't contain.

4. I stopped heating food in plastic

The swap: Black+Blum Containers 

I still have plastic containers in my kitchen. I just don't use them for hot food anymore.

Why: "Rather than replacing every plastic item in my kitchen, I prioritised those exposed to heat," says Dr. Irechukwu, who uses glass for storage and stainless steel for hot food herself. Heat is the trigger because chemicals used in some plastics, including bisphenols and phthalates, can migrate into food, and research has linked certain members of these chemical groups to hormonal effects. Exposure to bisphenols and phthalates is widespread, although what low-level exposure means for an individual is difficult to establish.

What to look for: Dr. Lewis keeps it simple here. No microwaving in plastic, no pouring very hot food into it when glass, ceramic, or stainless steel is available, and take extra caution with old, scratched containers or reused takeaway boxes. Cold storage in plastic isn't the part to worry about.

5. I switched to tampons with transparent batch testing

The swap: Daye Organic Non-Toxic Tampons 

I'd used tampons every month for years without giving much thought to what they're actually made from. Once I started thinking about repeated exposure, a product that sits inside the body for hours felt worth understanding properly.

Why: The vaginal lining has a rich blood supply and is more permeable than skin, which is part of why Dr. Irechukwu places menstrual products higher on her own priority list. That doesn't make conventional tampons unsafe. UK and EU manufacturing moved away from the chlorine-bleaching processes once linked to dioxin concerns years ago, and current evidence doesn't point to an immediate health risk from conventional use. A 2024 study did detect metals in both organic and non-organic tampons, but couldn't establish how much, if any, actually leaves the product or enters the body, and organic wasn't consistently cleaner. 

Dr. Lewis is direct that the evidence doesn't currently support telling women they need organic tampons to protect their hormones. I switched to Daye for the batch testing and transparency rather than the "organic" label alone. Both experts also point to menstrual cups as an alternative. Dr. Irechukwu uses one herself, and Dr. Lewis points to a 2019 review of 43 studies finding cups a safe option with comparable or lower leakage than pads or tampons.

What to look for: a brand that speaks out about what it tests for, not just what it's free from. If you're curious about cups, they also have a reassuring safety evidence base.

6. I rethought how I was fragrancing my home

The swap: fresh air, fewer aerosols, and candles I've actually thought about

This one cost me almost nothing. I used to treat scent as part of a clean-smelling home. Now, I question how much of it I actually need in the air all day.

Why: "As a respiratory physiologist, indoor air quality is something I think about a lot," says Dr. Irechukwu. Heavily fragranced cleaning products, air fresheners, and aerosols release VOCs, volatile organic compounds, which most healthy people won't notice but which can trigger coughing, wheezing, or chest tightness in people with asthma or fragrance sensitivity. Dr. Lewis flags the same category, plus candles, which can add particulate matter and volatile compounds when burned for hours in a closed room. Her concern is continuous background exposure, not the occasional scented product.

What to do: Open windows regularly, ventilate while cleaning and cooking, apply cleaning sprays to a cloth where practical, and avoid continuously fragrancing rooms. I still light candles, but I don't burn several for hours every evening in a closed room. Ventilation is the change I've prioritised rather than trying to find a supposedly "non-toxic" candle.

7. I became more selective about my beauty stash 

The swap: more considered deodorant, moisturiser, and fragrance

Deodorant and moisturiser stood out to me first, since I use both every day, sometimes twice, and they stay on my skin rather than getting rinsed off. Perfume followed for the same reason once I thought about it properly.

Why: "Leave-on products should naturally move higher up your priority list than products that are rinsed away because they remain in contact with the skin for much longer," says Dr. Irechukwu. That's a reason to look closer, not a reason to assume they’re harmful.

Antiperspirant is the clearest example of where the research challenged what I'd seen online. Aluminium salts temporarily reduce sweating, but large reviews haven't found convincing evidence linking aluminium-containing antiperspirants to breast cancer.

Fragrance is another formulation detail I've started looking at. Dr. Lewis points out that certain phthalates have been used in fragranced products, including some personal-care formulations. For me, that made fragrance something worth checking rather than something I felt I needed to avoid altogether.

"Natural" doesn't automatically solve this either. Fragrance and essential oils can irritate some people's skin, while synthetic ingredients can be used safely at the levels found in cosmetic products. I'm interested in what a product contains, how often I'm using it, and how my skin responds to it, rather than whether the label looks particularly "clean".

What to look for: start with the products you use most often and leave on longest. Look for ingredient transparency and clear fragrance disclosure, or phthalate-free formulations if that's something you're specifically trying to reduce. The product still needs to do its job. A shorter or more natural-looking ingredient list isn't automatically a better one.

8. I started taking household dust more seriously

The swap: shoes off, regular hoovering, damp dusting and mopping

Dust was nowhere near my original list, which is exactly why this one surprised me. 

Why: Chemicals used in furnishings, flooring, electronics, and treated textiles don't always stay locked inside the product. Some migrate into household air and settle in dust. Dr. Lewis points to flame retardants as one example, historically used in mattresses and carpets, with research raising questions around endocrine, thyroid, reproductive, and developmental effects. Shoes can also track outdoor pollutants, including pesticide residues, into the house. None of this makes the dust behind your sofa an emergency. It just gives regular cleaning a second purpose.

What to do: take your shoes off at the door, hoover regularly, damp-dust rather than dry-dust so you're actually removing particles, and mop hard floors. 

9. I check what furniture and textiles are treated with before I buy new ones

The swap: fewer unnecessary stain- and water-resistant finishes

This is the slowest change I've made because I'm not replacing a perfectly good sofa or mattress in pursuit of a chemically pristine home.

Why: PFAS have historically been used in some textiles and furnishings for their stain- and water-repelling properties. Their persistence in the environment, and the fact that certain PFAS can accumulate in the body over time, has driven ongoing research and regulatory attention. Studies have associated exposure to some PFAS with reproductive, developmental, and metabolic effects, although that doesn't mean owning a treated sofa or waterproof jacket will cause those outcomes.

Dr. Lewis now checks the materials and treatments used when buying mattresses, sofas, carpets, bedding and clothing, particularly whether stain- or water-resistant treatments have been added unnecessarily.

I'm doing the same when something needs replacing. I want to know what it's been treated with and whether I actually need that extra finish in the first place.

What to do: wait until something needs replacing, then check what it's made from and whether stain-, grease- or water-resistant treatments have been added. If an untreated or PFAS-free option works just as well for what you need, that's an easy point at which to make a different choice.

The things I haven't thrown away

My microwave is still very much plugged in. It just isn't heating anything in plastic anymore. Every synthetic cleaning product under my sink is still there too. So is my antiperspirant, most days. None of that made the cut for a swap, and that's the point.

Researching this made me more wary of sweeping "toxic" claims. An intact non-stick pan used properly is considered safe. Current evidence hasn't shown conventional tampons damage your hormones. Aluminium antiperspirant hasn't been convincingly linked with breast cancer. UK tap water is safe to drink. Natural doesn't automatically mean safer. Those caveats aren't inconvenient footnotes, they're what make the real changes easier to spot.

What's actually changed is how I decide what's worth acting on. Something I use twice a day earns more scrutiny than something I encounter twice a year. Heat changes how I think about plastic. A product sitting against my skin for eight hours gets a closer look than something I rinse off in 30 seconds. Damaged cookware gets replaced before perfectly functional pans do. An open window usually comes before another product designed to make the air smell "clean".

Dr. Irechukwu sums it up better than I could. "Non-toxic living isn't about throwing everything away and starting again. It's about understanding where your biggest everyday exposures are and making thoughtful changes over time. Science shouldn't make us fearful, it should help us prioritise."

That's probably the only "non-toxic living" rule I'm interested in keeping.
