We recommend changing the ceramic filter element every six months to retain maximum effectiveness.

To change the filter, simply place a cloth underneath the system, open your tap/faucet to relieve the pressure in the filter, and then twist the Kingfisher to the ‘V’ vent position to release it from its housing to access the ceramic filter inside. Simply unscrew it from the mount and change to your new filter!

Can a Netflix-Inspired Plastic Detox Really Work?
Concerns about plastic exposure and its effects on human health have risen sharply recently. As uncertainty around the long-term implications continues, a growing body of research is emerging, increasingly highlighting the risks associated with the microplastics and nanoplastics we encounter and often consume throughout our daily lives. Netflix's most recent documentary, “Plastic Detox", features a fascinating real-world experiment that has brought the issue into an even sharper focus. For couples trying to conceive, this topic is particularly relevant, as emerging research suggests environmental factors, including everyday plastics, could be playing a much bigger role in fertility than previously thought. Plastics Aren’t Just an Environmental Concern. They also pose a significant risk to human health. Many plastics contain chemicals such as phthalates, which make them flexible, and bisphenols like BPA, which make them rigid. These substances are known as endocrine disruptors, meaning they can interfere with the body’s hormonal system, affecting key functions like fertility, metabolism, and growth and development. What makes this particularly concerning is how easily these chemicals can enter the body through the food and drink we consume, via skin absorption (which can account for up to 60% of exposure), and even through the air we breathe in the form of microplastics. The Bigger Picture: What Research Shows Scientific studies back up the concerns: A landmark Danish study found a 50% decline in sperm count over 50 years Newer data suggests the decline is accelerating Exposure to phthalates in infancy is linked to future fertility issues Over 50 chemicals act as “obesogens”, contributing to weight gain BPA may affect multiple generations, not just one There’s also emerging evidence linking plastic chemicals to: Cardiovascular disease ADHD and autism Hormone-related cancers The Netflix Study: Can Reducing Plastics Improve Fertility? Six couples who had been struggling to conceive due to "unexplained infertility" after medical testing took part in a three-month experiment. The hypothesis was simple: If we reduce exposure to plastic chemicals, can fertility improve? Participants were tested for: Bisphenol A (BPA) Phthalates Sperm count and concentration (male partners) Since sperm takes around 70 days to regenerate, the study tracked changes over a 3-month period to see whether lifestyle adjustments made a measurable difference. Real Results from Real Couples The outcomes were striking and, for some of the couples featured, life-changing: Monique and Bruno (2 years trying)Bruno (a construction worker) changed aspects of his home and work environment and saw an 84% increase in sperm concentration. The couple later had their first child and are expecting another in 2026. Julie and Eric (2.5 years trying)Despite Eric being classified as subfertile, the couple successfully conceived. Their baby was born in early 2026. Katie and Tim (10 years trying)No improvement was observed in this case. A reminder that fertility is complex and multi-factorial. Darby and Jesse (22 months trying)Initially showed extremely high BPA and phthalate levels. After just 6 weeks: Darby’s BPA dropped by 95% Both partners saw significant chemical reductions They later conceived and welcomed a baby in 2026. Overall, 50% of couples featured conceived after the study, and after 6 weeks, all of the couples showed a decrease in BPA of 61.5%, making it almost non-detectable. Phthalates also declined by 6.25%. Along with fertility, a third of the participants saw a lower BMI; 60% reported higher energy levels; 80% reported increased sleep quality; and 86% said they planned to keep the lifestyle changes. What Changed? (The “Plastic Detox” Approach) Rather than eliminating everything, participants focused on reducing the largest sources of exposure in their everyday lives. Key Changes: Avoiding plastic food and drink packaging Switching to natural, fragrance-free personal care products Reducing exposure to synthetic fabrics Avoiding thermal receipts (a hidden BPA source) Replacing common household items with plastic-free alternatives Common Plastic Sources in Our Homes: Of course, plastic regulations vary around the world. The Plastic Detox featured couples based in America. So, it's important to note, while the UK and EU follow frameworks like REACH (Registration, Evaluation, Authorisation, and Restriction of Chemicals), with 1,100 chemicals banned in EU cosmetics compared to just 9 in the US, there are still common places where plastics can be found throughout our homes. Such items can include: Plastic bottles and food packaging Tea bags (many contain plastic fibres) Coffee pods Shampoo and toiletry bottles Cleaning products Synthetic clothing (polyester, nylon) Plastic chopping boards Children’s toys Fragrances and cosmetics How to Reduce Exposure to Microplastics Around Your Home: You don’t need to overhaul your entire lifestyle overnight to reduce plastic exposure. In fact, small, consistent swaps can make a meaningful difference. A wonderful place to start is in the kitchen, where plastics are often most heavily used. Switching to glass or stainless steel containers for food storage, choosing wooden or bamboo chopping boards, and avoiding plastic kettles or containers where possible can all help lower your exposure to harmful chemicals. Consider investing in a water filter system to further reduce your consumption. This is particularly important if you and your family frequently use plastic bottles instead of tap water to lower microplastics in water. It’s also worth looking at your daily routine. Many personal care products contain hidden plastics or synthetic fragrances, so opting for fragrance-free toiletries and products in plastic-free or refillable packaging is a simple but effective change. Clothing is another often-overlooked source of microplastics, so where possible, choosing natural fibres like cotton or wool can help reduce both personal exposure and environmental impact. Try not to buy polyester or waterproof clothing where possible, as these may also contain avoidable plastic particles and chemicals. Finally, being aware of less obvious sources of plastic can go a long way. Even everyday items like receipts often contain BPA, so limiting how often you handle them is a good habit to build. When food shopping, choosing loose fruit and vegetables instead of pre-packaged options can significantly cut down plastic use. Even something as simple as checking whether your tea bags are plastic-free can contribute to a lower overall exposure. While these tips may sound a little overwhelming, with plastic appearing to be present in almost everything we touch, it's still important to note that, like everything in life, smaller, more manageable changes are still beneficial for longer-term goals. Will You Reduce Your Plastic Exposure? The biggest takeaway from the 'Plastic Detox' isn’t perfection; it’s awareness. For UK families, especially those trying to conceive, reducing plastic exposure could be a simple but powerful step toward better health. While fertility is influenced by many factors, this study suggests something encouraging: Everyday choices, even small ones, may have a bigger impact than we think.
