Clean drinking water is something most of us take for granted. You turn on the tap, fill a glass, and expect fresh, healthy water every time. But in recent years, more homeowners across the UK have started paying closer attention to what is actually in their tap water.

From chlorine taste and limescale to concerns about contaminants travelling through ageing pipe systems, many people are now looking for ways to improve the quality of the water they drink every day. That is why the demand for a reliable water filter has grown rapidly.

Is Tap Water Really Clean?

UK tap water is regulated and generally considered safe to drink. However, “safe” does not always mean ideal in terms of taste, odour, or overall quality.

Water can pick up impurities as it travels through old plumbing systems and household pipes. Depending on where you live, you may also notice:

  • Chlorine taste or smell
  • Hard water and limescale
  • Sediment and rust particles
  • Cloudy water
  • Poor taste in tea and coffee

Many households simply want cleaner and better-tasting water without relying on expensive bottled water.

According to information about public water systems and consumer concerns around tap water quality, many people choose filtered water because of taste, odour, and confidence in water quality

PFAs in Drinking Water: The Hidden Contaminants You Cannot Taste

What you can taste is often chlorine, metallic notes, or the effects of hard water. What you usually cannot taste are substances such as PFAs (per- and polyfluoroalkyl substances) and trace pharmaceutical residues. PFAs are often referred to as “forever chemicals” because they break down extremely slowly and can remain in the environment and water systems for many years. They have been widely used in products such as non-stick cookware, waterproof clothing, food packaging, and industrial materials.

Unlike chlorine or limescale, PFAs are invisible, odourless, and tasteless, meaning they can be present in drinking water without any obvious warning signs. This is one reason why more households are turning to a high-quality water filter — not only for better taste, but for greater peace of mind and confidence in the quality of their clean, safe water.

Your tap water is treated, but that does not necessarily mean it is completely clean

Despite increasing awareness, the UK currently has no specific legally binding limit for PFAS in drinking water.

Water quality standards were created decades ago, long before many of today’s emerging contaminants became widely recognised. Our water sources have changed over time, but regulations have struggled to keep pace.

Water treatment facilities work hard to purify drinking water before it reaches your home — but the journey through ageing pipe systems can still affect water quality.

Across the UK, millions of older properties are believed to remain connected to lead service pipes installed decades ago. While replacement programmes are ongoing, upgrading national infrastructure is a long-term process that could take many years.

One of the concerns with older plumbing is that lead can enter water supplies without any visible warning signs. Unlike chlorine or hard water minerals, lead cannot usually be seen, tasted, or smelled. According to the World Health Organization, there is no known safe level of lead exposure, particularly for children and pregnant women.

By the time water reaches your tap, it may have travelled through miles of underground infrastructure and household plumbing. Even if water leaves the treatment plant in excellent condition, what it encounters along the way can influence the quality of the water that ends up in your glass.


Traditional jug filters were introduced decades ago, but modern water concerns have evolved significantly since then

Most standard jug filters use a simple plastic housing with a basic carbon cartridge designed primarily to improve taste and reduce chlorine odour. While they can help make water more pleasant to drink, many were not originally developed to address the wider range of contaminants being discussed today.

Emerging concerns such as PFAS chemicals, microplastics, lead, and trace pharmaceutical residues require more advanced filtration technology than many basic jug filters are designed to provide. As awareness around water quality grows, more households are now looking toward higher-performance filtration systems that offer deeper purification while still maintaining essential mineral content.

Water in traditional filter jugs often remains stored in a plastic container for extended periods at room temperature. Over time, stagnant water conditions can increase the risk of bacterial build-up, while prolonged contact with plastic may also contribute to concerns around microplastic exposure.

While jug filters were once considered a convenient solution decades ago, modern water quality concerns have led many households to seek more advanced and hygienic filtration systems better suited to today’s standards.

Hidden Pesticide Residues in Tap Water

Some agricultural chemicals can remain in water sources long after their use has been restricted or banned.

Water utilities routinely test for regulated contaminants, but growing attention is also being given to chemical by-products and metabolites formed as substances break down over time. These trace compounds may still be present in water systems, even when they are not part of standard household monitoring programmes.

Microplastics in Tap Water: The Particles You Cannot See

Studies around the world have detected microplastics in a large percentage of tap water samples, raising growing concerns about long-term exposure through everyday drinking water.

One of the biggest challenges is that many of these particles are extremely small — often below the size limits used in standard monitoring methods. As a result, a significant proportion of microplastics may not be fully captured by current testing frameworks or routine water analysis.

Because these particles are microscopic, they are invisible to the naked eye and can pass through water systems unnoticed. Although research into their health impact is still ongoing, increasing awareness of microplastics has led many households to seek more advanced water filtration solutions for added peace of mind and cleaner, safer drinking water.

Why a Water Filter Makes a Difference

A high-quality under sink water filter helps reduce unwanted substances while improving the taste and clarity of your drinking water.

Unlike bottled water, a modern filtration system provides continuous access to clean, safe water directly from your kitchen tap.

Benefits of installing a water filter include:

  • Improved taste and smell
  • Reduction of chlorine and sediment
  • Cleaner water for cooking Less reliance on plastic bottles
  • Better tasting tea, coffee, and ice
  • Convenient access to filtered water every day
  • Peace of mind for being PFA’s free.

Maintain Mineral Content While Filtering Impurities

One of the biggest misconceptions about filtered water is that it removes everything from the water.

In reality, many advanced filtration systems are designed to maintain mineral content while reducing unwanted contaminants. This means your water can still contain beneficial minerals such as calcium and magnesium while tasting cleaner and fresher.

This balance is especially important for people looking for healthier hydration without stripping water completely.

The Rise of Alkaline Water

Another growing trend is alkaline water. Many people prefer alkaline water because of its smoother taste and mineral-rich profile.

Some water filtration systems are specifically designed to support alkaline filtration by helping maintain essential minerals that naturally contribute to balanced water quality.

While preferences vary, more households are now searching for ways to enjoy fresh alkaline water from home without constantly purchasing bottled alternatives.

Why Under Sink Water Filters Are So Popular

An under sink water filter is one of the most practical solutions for modern homes.

Because the system is installed beneath the sink, it stays hidden while providing filtered water directly from a dedicated tap or your main kitchen tap.

Homeowners prefer under sink systems because they:

  • Save counter space
  • Provide larger filtration capacity
  • Require less frequent refilling
  • Deliver continuous filtered water
  • Offer a cleaner kitchen appearance

They are ideal for families who want a long-term solution for cleaner and safer drinking water.

Choosing the Right Water Filter

Not all filtration systems are the same. When choosing a water filter, it is important to look for:

  • Reliable filtration performance
  • Long-lasting filter cartridges
  • Mineral retention capability
  • Easy maintenance
  • Compatibility with UK plumbing systems

A quality system should improve water quality while still preserving the natural characteristics that make water refreshing to drink.

Cleaner Water for Everyday Life

Whether you are making tea, preparing meals, filling a reusable bottle, or simply enjoying a cold glass of water, having access to safe water matters.

More UK households are now investing in filtration systems because they want confidence in the water they drink every day.

Ultrafiltration (UF): Eco-Friendly Filtration That Keeps Healthy Minerals

An Ultrafiltration system paired with activated coconut carbon is a powerful and environmentally friendly way to purify tap water.

UF systems use a 0.01-micron membrane to remove contaminants such as:

Unlike some filtration systems, UF technology preserves naturally occurring minerals, which means your water remains healthy, balanced, and naturally alkaline.

Another major advantage is efficiency. UF systems do not require a drain line, high water pressure, or electricity, and they produce no wastewater, making them an excellent eco-friendly filtration solution for most municipal water supplies.

Reverse Osmosis (RO): Maximum Purification for Challenging Water

Reverse Osmosis systems provide a higher level of purification, making them ideal for areas where water contains high levels of dissolved solids or contaminants.

This process produces extremely pure water, but it does come with some trade-offs. Reverse Osmosis systems typically:

  • require more maintenance
  • produce some wastewater
  • remove beneficial minerals along with contaminants

As a result, RO-filtered water can become slightly acidic unless remineralisation filters are added.

Key Differences Between UF and RO Systems

UF + Activated Coconut Carbon

Best for municipal or tap water with moderate contamination.

Benefits include:

  • removes bacteria and particles
  • removes PFA’s
  • eliminates chlorine
  • removes microplastics
  • retains healthy minerals
  • produces no wastewater
  • low maintenance

RO + Activated Coconut Carbon

Best for high-TDS or heavily contaminated water sources.

Benefits include:

  • removes dissolved salts and metals
  • eliminates most fluoride
  • provides near-distilled water purity

However, it typically requires more frequent filter changes and higher system costs.

Reverse Osmosis (RO) Water Filter – Benefits

RO uses a very fine membrane (~0.0001 microns) that can remove dissolved substances and extremely small contaminants.

Key Benefits

  • Removes dissolved contaminants
    • Fluoride
    • Nitrates
    • Chemicals and pesticides
  • Removes microorganisms
    • Bacteria
    • Viruses
    • Parasites
  • Produces very pure water
    • Removes up to 95–98% of dissolved solids.
  • Improves taste and odor
    • Removes chlorine, salts and unpleasant minerals.
  • Useful for hard or contaminated water
    • Can reduce high TDS (total dissolved solids) levels.
  • Can desalinate water
    • Removes salt from seawater or brackish water.

Best for

  • Areas with poor or contaminated water quality
  • Hard water
  • When maximum purity is required

Downsides

1. Water Waste

RO systems typically waste more water than they produce.

  • Many standard systems discard 2–4 litres of water for every 1 litre filtered.
  • More efficient systems exist, but wastewater is still a common criticism.
  • This can increase water bills and may be an environmental concern.

2. Removes Beneficial Minerals

RO membranes remove not only contaminants, but also naturally occurring minerals such as:

  • Calcium
  • Magnesium
  • Potassium

This can make the water taste “flat” to some people. Many systems now add remineralisation stages to address this.

3. Slower Water Production

RO filtration is relatively slow compared with normal taps or simple carbon filters.

  • Most systems use a storage tank because filtration alone cannot keep up with instant demand.
  • If the tank empties, refill time can take hours.

4. Installation Complexity

Under-sink RO units are more complicated than basic filters.

  • Usually require plumbing modifications
  • Need drain connections
  • Take up cabinet space
  • Some households may need professional installation

Countertop systems are easier but often bulkier.

5. Ongoing Maintenance Costs

RO systems require periodic replacement of:

  • Sediment filters
  • Carbon filters
  • RO membrane

Membranes can be relatively expensive, especially if neglected or exposed to hard water.

6. Can Lower Water Pressure

Because water passes through a semi-permeable membrane, flow rates are often slower.

  • Dedicated RO taps typically have lower pressure than normal kitchen taps.
  • Tankless systems can sometimes improve this but may need electricity.

7. Electricity Use (for Some Models)

Traditional tank systems usually do not require power, but:

  • Tankless RO systems often use electric pumps
  • Smart models may require continuous power

This adds complexity and small ongoing energy costs.

8. Removes Chlorine — But Can Encourage Bacterial Growth if Neglected

RO systems remove disinfectants like chlorine.

If filters are not changed regularly:

  • Bacteria can grow inside stagnant tanks or tubing
  • Poor maintenance can reduce water quality instead of improving it

9. Not Always Necessary

In many parts of the United Kingdom and other developed countries, tap water is already highly regulated and safe.

An RO system may be excessive unless you specifically need:

  • Reduction of limescale minerals
  • Removal of nitrates/heavy metals
  • Better taste
  • Aquarium or coffee brewing water
  • Extra filtration for immune-compromised individuals

10. Space Requirements

Most under-sink systems need:

  • A filter assembly
  • A pressure tank
  • Tubing and valves

This can significantly reduce storage space in smaller kitchens.

11. Potentially Corrosive Water

Very low-mineral water can become slightly more aggressive toward metals.

In some setups:

  • RO water may slowly leach metals from certain plumbing materials if improperly configured.
  • This is usually minor in domestic use but relevant for long-term storage or specialised plumbing.

12. Noise

Some systems:

  • Gurgle during wastewater discharge
  • Make pump noise during refill cycles

Tankless electric units can be noticeably louder.

Ultrafiltration (UF) Water Filter – Benefits

UF membranes have larger pores (0.01–0.1 microns) and act like a microscopic sieve.

Key Benefits

  • Removes physical contaminants
    • Bacteria
    • Viruses
    • Sediment
    • Rust
    • Algae and cysts
    • PFA’s & microplastics
  • Keeps beneficial minerals
    • Calcium
    • Magnesium
  • No electricity required
    • Often works with normal water pressure and is silent.
  • No or very little water waste
    • High water recovery (around 90–95%).
  • Faster filtration
    • Higher water flow rate compared with RO.
  • Lower maintenance and operating cost

Best for

  • Areas with good municipal tap water
  • People who want minerals retained
  • Situations where electricity or water waste is a concern

Bottled Water Contains 240,000 Plastic Particles Per Liter — Switch to Filtered Water to Reduce Exposure by 90%

Plastic bottled water is a staple on desks, kitchen countertops, and bedside tables — but it comes with hidden health risks. Furthermore, researchers have discovered that a single litre of bottled water contains an average of 240,000 plastic particles, with 90% being nanoplastics. This is 10 to 100 times more plastic than previous estimates, which focused mainly on larger microplastics.

The Hidden Dangers of Bottled Water

Microplastics and nanoplastics from bottled water can enter your bloodstream and even cross the blood-brain barrier, leading to potential health risks such as:

  • Inflammation
  • Hormonal disruption
  • Neurological issues

How to Reduce Plastic Exposure by 90%

Switching from bottled water to filtered tap water is one of the simplest and most effective ways to cut down on microplastic intake by up to 90%.

Glacier Preservation

Glaciers are melting faster than ever. As the planet gets hotter, our frozen world is shrinking, making the water cycle more unpredictable.

Moreover, for billions of people, meltwater flows are changing, causing floods, droughts, landslides and sea level rise. Countless communities and ecosystems are at risk of devastation. As we work together to mitigate and adapt to climate change, glacier preservation is a top priority. We must reduce greenhouse gas emissions to slow down glacial retreat and manage meltwater more sustainably. Saving our glaciers is a survival strategy for people and the planet.

Observe World Water Day annually on March 22. It is dedicated to highlighting the importance of freshwater and the sustainable management of water resources. Each year, UN-Water selects a theme to focus global attention on specific water-related issues.

The theme for World Water Day 2025 is “Glacier Preservation.” This theme emphasizes the critical role glaciers play in global water systems, as their meltwater is essential for drinking, agriculture, industry, clean energy production, and maintaining healthy ecosystems. It also addresses the urgent need to mitigate their rapid decline due to climate change by reducing greenhouse gas emissions and managing meltwater sustainably

What can be done about rust, lead and other metals in your water supply?

metals chart

Rust and oxidisation can be incredibly common in water systems, particularly where pipes are older or there are other systems further up the pipeline that affect the water quality. In a lot of cases, although you can replace the pipes and systems in your house, there’s little that you can do about elements out of your control.

Some might be shocked to learn that levels of lead can still be found in our drinking water. That’s right! High levels of exposure to lead can poison our bodies, with nasty symptoms such as abdominal pain, memory loss, or even miscarriage or premature birth in pregnant women. Copper is the most common heavy metal that appears in tap water. Copper is another essential element to your health, but too much of it can cause vomiting, diarrhoea, stomach cramps, and even kidney and liver disease.

So, what’s the solution?

Ultrafiltration is the filtration method of choice for people who prefer minerals left in their water but still want microscopic contaminants removed. Ultrafiltration operates at a low pressure, effectively removing all bacteria and viruses as well as other contaminants such as heavy metals, rust, chlorine and limescale. You’ll see the immediate difference in both your Kettle and Iron. Our device is about as compact as you’ll find for a three-cartridge system and is quick and easy to install.

Currently, drinking water in the UK, must contain PFAS chemicals at no more than 100 nanograms per litre (ng/l) before action is taken. We feel this is much too high when health effects at lower and lower concentrations are being found. We are beginning to think that there is no such thing as a safe level!

Our filters are an ultrafiltration system that operates without electricity, making it an eco-friendly and cost-effective choice. Its compact design takes up minimal space under your sink.

This ultrafiltration filter features a 0.01-micron rating, allowing it to effectively remove the results of iron oxidisation in the form of rust and other contaminants from water.

We hope that our water filters, once easily installed, can be a positive step forward to preventing dire long-term health effects and ease some of the anxiety surrounding the problem of high concentrations of PFAS in our water supply.
