Home and Living
The home is where exposure is constant. Here is what to change and why it matters.
JUMP TO
The home is where exposure happens most often and is noticed least.
Food is bought occasionally and eaten consciously. Skincare is applied once or twice a day. But the home surrounds you constantly. The pan you cook with several times a week. The cleaning products used in every room. The candle burning in the background while you relax. The water that fills your kettle, your pasta pot, the glass beside the bed.
Most people never realise how exposed they really are. Heat, friction and time all release particles and compounds into the air you breathe and the food you eat, often without any obvious sign that it is happening.
This page covers the five areas of the home where the evidence for hidden exposure is strongest, and what to do about each one.
Non Stick Cookware and PFAS
Non stick coatings like Teflon belong to the PFAS family of forever chemicals we cover on our Start Here page. They do not break down naturally in the environment or in the human body.
Under normal use, a small amount of coating wears away over time and ends up in food. Under high heat, particularly when a pan is left empty on a hot burner or used above its rated temperature, the coating can begin to break down and release particles and fumes directly into the air.
PFAS exposure has been linked to reproductive issues, immune system disruption, thyroid problems and increased risk of certain cancers. The UK Government's first PFAS Plan, published in February 2026, found PFAS contamination in 88% of surface water samples tested across England.
The fix here is genuinely simple and does not require sacrificing performance in the kitchen.
Cast Iron
Naturally non stick once properly seasoned, lasts a lifetime with basic care, and adds trace amounts of dietary iron to food. The heavier weight is the only real trade off.
Stainless Steel
Durable, does not react with acidic foods, and performs well at high heat.
Ceramic Coated
A genuine PFAS free alternative when made by a reputable manufacturer. Look for products that explicitly state PFAS free or PTFE free, as the term ceramic alone is sometimes used loosely in marketing.
Cleaning Products
Most mainstream cleaning products are not required to list their full ingredients on the label, unlike food and cosmetics. This makes the cleaning cupboard one of the least transparent parts of the home.
Many conventional cleaning sprays, surface cleaners and air fresheners contain phthalates used to carry fragrance, alongside other volatile organic compounds that are released into the air during and after use. These compounds are inhaled directly, which is a faster route into the bloodstream than skin absorption.
Products listing fragrance or parfum without disclosure, anything labelled antibacterial that lists triclosan, and aerosol sprays in general due to fine particle inhalation.
Plant based cleaning brands that fully disclose ingredients, or simple alternatives like white vinegar diluted with water for most surfaces, and bicarbonate of soda for scrubbing.
A basic mix of white vinegar, water and a few drops of an essential oil cleans most household surfaces effectively and costs a fraction of branded sprays.
Candles and Air Fresheners
Scented candles and plug in air fresheners are among the most concentrated sources of indoor air pollution in an average home, despite feeling cosy and harmless.
Most mass market candles are made from paraffin wax, a petroleum byproduct. When burned, paraffin releases volatile organic compounds including benzene and toluene. The synthetic fragrance used to scent them frequently contains phthalates, the same chemicals covered on our Beauty and Skincare page, except here they are released directly into the air and inhaled rather than absorbed through skin.
Plug in air fresheners work on a similar principle, continuously releasing synthetic fragrance compounds into a room over hours or days.
Beeswax or soy wax candles scented only with essential oils. A worthwhile clarification: claims that beeswax candles purify the air or release beneficial negative ions are not supported by peer-reviewed science, despite appearing on many wellness websites. The genuine advantage of pure beeswax is simply that it contains no synthetic fragrance, dye or paraffin byproducts, which is a real benefit in itself.
Opening windows for genuine ventilation remains the most effective and free option. A simple essential oil diffuser with water offers scent without combustion or synthetic fragrance.
Water Filtration
Tap water in the UK meets legal safety standards, but legal safety and genuinely clean are not always the same thing. Standard testing does not screen for every PFAS compound or pesticide residue, and the UK Government's own February 2026 PFAS Plan confirmed contamination in the majority of surface and groundwater samples tested nationally.
A good water filter at home removes a meaningful proportion of pesticide residues, PFAS compounds, chlorine byproducts and heavy metals before water reaches your glass, your kettle or your cooking pot.
The lowest cost entry point. Reduces chlorine and some heavy metals, though filtration of PFAS specifically varies significantly by brand and filter type.
A higher upfront cost but typically more thorough filtration, including some models specifically certified to remove PFAS.
The most thorough option available for home use, removing the widest range of contaminants including PFAS. The highest cost and requires more maintenance than other options.
When choosing any filter, check whether the manufacturer publishes independent testing data specifically for PFAS removal rather than relying on general marketing claims.
Plastic in the Kitchen
Plastic storage containers, chopping boards and utensils are everyday items that most people never think to question, yet they represent a steady, low level source of chemical exposure that accumulates over years of use.
Plastic leaches more readily when it is heated, scratched, old, or in contact with fatty or acidic food. A scratched plastic chopping board or a container that has been through the microwave hundreds of times is releasing more particles into food than a brand new one.
Switch to glass containers with stainless steel or glass lids. Never microwave food in plastic, even containers labelled microwave safe, as heat significantly increases the rate of leaching.
Wooden or bamboo boards do not shed microplastics the way plastic boards do. Wood also has natural antibacterial properties, meaning bacteria survives less easily on its surface between washes.
Stainless steel or glass kettles avoid the plastic components found inside most standard kettles, which sit in direct contact with boiling water multiple times a day.
None of these changes need to happen at once. The home accumulates exposure slowly, over years, through habits repeated without thought. Reducing it works the same way, one habit changed at a time.
Start with whichever feels most achievable today. The pan you cook with tonight is as good a place as any.
Your home should work for your health, not against it.
