Benefits of Filtered Water Backed by Science in 2025
2025 research shows why water filtration is no longer optional for many UK homes.
You pour a glass from the tap. It looks clear, and it might even taste fine. But is it as safe and healthy as it seems?
New data from 2025 reveals that UK tap water meets legal standards. Yet, despite this, it can still have small amounts of chlorine, lead, and pesticide residues. This is especially true in hard water areas or homes with ageing pipes. Over time, even small amounts of these contaminants may affect your hydration, digestion, and skin health.
That’s why more UK households are switching to filtered water. It's not just for taste but for long-term wellness, cost savings, and peace of mind. Backed by science, modern filters go beyond what you can see or taste. Keep reading for a breakdown on what’s really in your tap water, what filters remove, and how this simple daily change can make a big impact.
What Are the Benefits of Filtered Water in 2025?
Filtered water supports better health, better hydration, and a cleaner planet.
Today’s filtration systems do more than eliminate tap water’s metallic taste; they also lower harmful substances that can affect health. According to The Guardian, DEFRA says trace pollutants, including chlorine, lead, and PFAS chemicals, are rising in UK water supplies. This is particularly noticeable in regions with hard water.
Filters designed for UK homes remove these contaminants while preserving essential minerals. In 2025, new studies showed that these improvements result in healthier skin, better digestion, and all-day energy.

What’s Really in Your Tap Water Today?
Legally clean doesn’t always mean contaminant-free.
UK tap water is among the most tightly regulated in the world. Many homes, especially older buildings, still face risks from old plumbing and high mineral levels. In 2023, a BBC investigation found low levels of microplastics, drugs, and other pollutants in tap water in various UK areas.
Here are some of the most common substances detected:
- Chlorine: used to disinfect but leaves behind an odour and taste
- Lead: can leach from old pipes
- Copper: causes a metallic aftertaste
- PFAS chemicals: also known as “forever chemicals”
- Limescale: calcium deposits that affect appliances and flavour
While these are usually present in small amounts, research suggests they can accumulate in the body over time. That’s why many families are now filtering their water. It helps protect young children and those with sensitive skin or digestion.
Scientific Benefits of Filtered Water (Featuring 2025 Evidence!)
Research confirms that filtered water supports everyday health and performance.
The benefits of filtered water aren’t just about taste. They’re backed by 2025 studies showing real impact on hydration, energy, and wellbeing. Whether you’re active, health-conscious, or simply trying to drink more water, the science is now on your side.
Better Hydration, Focus, & Recovery
A 2025 study by the Mayo Clinic found that mineral-rich, pH-balanced water is absorbed better than untreated tap water. Participants reported faster post-exercise recovery, improved alertness, and reduced fatigue. That means more energy throughout the day, whether you’re at work, the gym, or just keeping up with life.
Lower Exposure to Tap Water Contaminants
Even in small amounts, substances like chlorine, lead, and copper can cause skin irritation and digestive problems. Over time, they may also harm the nervous system or affect reproduction. Modern filters, such as our Alkaline Refill Pack, are built to remove harmful materials whilst retaining important minerals, including magnesium.
Support for Skin, Gut, & General Wellness
Filtered water plays a subtle but consistent role in whole-body wellness. It helps the skin flush toxins more effectively, supports gut balance, and, thanks to its pH stability, may reduce symptoms of acid reflux. Small changes add up, especially when your water works with you, not against you!
Environmental Benefits of Filtered Water in 2025
Cutting plastic use starts with what you drink every day.
Plastic pollution remains one of the UK’s biggest environmental challenges. According to Water UK, the average Brit uses over 150 plastic bottles a year. Yet, even with our recycling infrastructure in place, many still end up in landfills or waterways.
Stop Buying Bottled Water
Switching to a refillable filter jug can eliminate the need for hundreds of bottles annually. A household with a countertop filtration system can stop more than 500 bottles from going to waste each year. Plus, it won’t affect water quality.
Smarter, Lower-Impact Delivery
Phox’s sustainability model takes this a step further. Our refill granules are delivered in slim, letterbox-friendly packs. Better yet, we use the Royal Mail’s carbon-efficient routes. Plus, design, packaging, and distribution happen right here in the UK. So, we’re keeping the environmental footprint low at every stage!
Cost Savings: Filtered vs Bottled Water
Cleaner water doesn’t have to cost more.
Bottled water may seem like a convenient alternative, but it’s expensive. It typically costs 30p to £1 per litre in the UK, depending on brand and packaging. Compare that to 3–5p per litre for filtered water at home, and the savings add up fast.
For a family of four, that difference could mean saving over £300 a year, not to mention reducing plastic waste and storage clutter. With Phox refills lasting up to 200 litres or 45 days, the system offers both long-term value and convenience.
Everyday Lifestyle Benefits Worth Noting
Better water leads to better habits and better wellbeing.
Filtered water doesn’t just improve health and reduce costs. It also enhances the quality of your daily routine.
- Enjoy tea, coffee, and meals that taste better: Chlorine and limescale are filtered out, allowing the natural flavours to shine through.
- Drink more without even trying: People tend to hydrate more when water tastes fresher and is always available.
- Stay on track with health goals: Proper hydration supports metabolism, appetite control, and clearer skin.
