Installing a water filtration system in your home is one of the smartest and most cost-effective upgrades you can make. From removing harmful contaminants to improving the taste of your tap water, the benefits of a water filtration system go far beyond hydration. Afterall, it isn’t called the ‘elixir of life’ for nothing!
Homeowners increasingly search for water filtration systems for homes that improve taste, reduce limescale, and provide whole-property protection.
Whether you're concerned about your family’s health, looking to extend the life of your appliances, or simply want better quality water, filtration is a clear solution.
At Maintracts, we help homeowners across London and the surrounding areas to enjoy cleaner, safer, and more reliable water - right from the tap. In this blog, we explain everything you need to know about water filtration systems and why you should use them.
What Is a Water Filtration System and How Does It Work?
A water filtration system is designed to remove impurities and contaminants from your tap water. These systems use various technologies, such as activated carbon, reverse osmosis, ultraviolet light, or ion exchange to treat water at different levels.
- Activated Carbon Filters remove chlorine, volatile organic compounds (VOCs), and improve taste.
- Reverse Osmosis Systems push water through a semi-permeable membrane, removing up to 99% of dissolved solids.
- UV Filters kill bacteria and viruses without chemicals.
- Ion Exchange Filters reduce hardness by replacing calcium and magnesium with sodium or potassium ions.
Systems can be installed at a single tap (point-of-use) or at your main water supply (whole-house filtration).
10 Key Benefits Of Installing A Water Filtration System
Improves Taste And Smell Of Tap Water. Tap water can carry an unpleasant taste or odour due to chlorine or other treatment chemicals. A filtration system eliminates these, leaving your water fresh, clean, and more enjoyable.
Removes Harmful Contaminants. Filtered water is free from common impurities found in UK tap water, such as lead, chlorine, pesticides, nitrates, microplastics, and bacteria. This means you’re drinking safer, healthier water every time you fill your glass.
Protects Your Plumbing And Appliances. Hard water can cause all sorts of damage such as limescale buildup, which damages pipes, boilers, and household appliances like kettles and washing machines. A filtration system reduces scale, protecting your plumbing infrastructure and prolonging the lifespan of appliances.
Promotes Better Health And Hydration. Clean, contaminant-free water is essential for hydration and general wellbeing. Many households report improvements in skin condition, digestion, and energy levels after switching to filtered water – perfect for our health-conscious generation.
Saves Money in the Long Run. While there’s an initial investment, water filtration systems reduce bottled water use, appliance repair costs, and energy inefficiencies caused by scale buildup.
Environmentally Friendly Alternative. If you are an eco-conscious homeowner, you’ll be pleased to know that switching from bottled water to a filtration system drastically cuts down plastic waste and your carbon footprint.
Ideal for Sensitive Skin Or Allergies. If you suffer from sensitive skin, or other skin conditions such as eczema or psoriasis, filtered water will make a huge difference with reducing irritation and providing relief. Fewer chemicals and cleaner water mean gentler showers and baths.
Convenience and Peace of Mind. With a home filtration system, clean water is available 24/7 from every tap—there’s no need to rely on jugs, bottled water, or last-minute filter replacements.
Whole-House Coverage Options. Whole-house water filtration ensures that every outlet, from your kitchen sink to your bathroom shower, provides purified water. It’s ideal for larger families or households with high water usage.
Increases Property Value. As a desirable choice for eco-minded and health-savvy buyers, a professionally installed filtration system can add long-term value to your property.

Water Filtration Systems for Homes: Types and How They Work
When looking at water filtration systems for homes, it’s important to understand that there isn’t a one-size-fits-all solution. Different systems are designed to target specific contaminants, water quality issues, and household needs. Choosing the right setup depends on your property, water usage, and whether you want point-of-use or whole-property coverage.
Below are the most common types of water filtration systems for homes, how they work, and what they’re best used for.
Under-Sink Water Filtration Systems
Under-sink systems are one of the most popular types of water filtration systems for homes, especially for drinking and cooking water.
These systems are installed directly beneath your kitchen sink and connect to a dedicated tap. They typically use activated carbon or reverse osmosis technology to remove chlorine, heavy metals, and other impurities.
They are ideal for homeowners who want high-quality drinking water without modifying the entire plumbing system.
Countertop Water Filtration Systems
Countertop systems are a simple and flexible option among water filtration systems for homes, particularly for renters or those who prefer a non-permanent solution.
These units sit on your kitchen surface and connect directly to the tap. Water is filtered on demand, improving taste and reducing common contaminants.
While convenient, they usually only serve one outlet, making them less suitable for full household coverage.
Whole House (Whole Home) Water Filtration Systems
Whole house systems (also known as whole-home systems) are the most comprehensive type of water filtration systems for homes.
Installed at the point where water enters your property, they treat all water before it reaches any tap, shower, or appliance.
This means every outlet in your home benefits from filtered water, including bathrooms, kitchens, washing machines, and boilers.
Whole-home systems are particularly effective in hard water areas like London, where limescale and sediment are common issues. They also provide consistent protection across the entire property, making them ideal for families and high-usage households.
Reverse Osmosis Water Filtration Systems for Homes
Reverse osmosis systems are one of the most advanced water filtration systems for homes, using a semi-permeable membrane to remove up to 99% of dissolved solids.
They are highly effective at producing extremely pure drinking water by removing contaminants such as lead, nitrates, fluoride, and microplastics.
These systems are often installed under the sink and are best suited for homeowners who prioritise drinking water quality above all else.
If you’re considering a drinking-water focused solution, our team can advise on reverse osmosis system installation for maximum contaminant removal.
UV Water Filtration Systems for Homes
UV filtration systems use ultraviolet light to disinfect water by neutralising bacteria, viruses, and other microorganisms.
Unlike other water filtration systems for homes, UV systems do not remove physical particles or chemicals. Instead, they focus purely on biological contaminants.
They are often used in combination with other filtration methods to provide a complete water treatment solution, particularly in homes with private water supplies or additional contamination risks.
Whole Home Water Filtration System Explained (Whole-House Systems for Properties)
A whole home water filtration system is a point-of-entry solution designed to treat all the water entering your property before it reaches any tap, shower, or appliance. Unlike smaller under-sink units, a whole home water filtration system provides complete household coverage, ensuring every outlet delivers cleaner, filtered water.
This type of whole home water filtration system is installed directly at the mains water entry point of your property (typically where the stopcock or main incoming supply is located). From there, every drop of water used in your home is filtered before it enters your internal plumbing system.
A whole-house filtration system is particularly beneficial for homes in London and other hard water areas, where water quality issues such as limescale, chlorine, and sediment are more common. Families and high-usage households often choose this solution because it provides consistent protection across bathrooms, kitchens, and appliances.
The benefits of a whole home water filtration system go beyond drinking water. As highlighted earlier in this guide, filtered water can help reduce limescale build-up, improve appliance efficiency, and enhance overall water quality throughout the home. This makes it a long-term investment in both health and property maintenance.
In terms of installation, a whole-house filtration system is typically fitted by a qualified plumber and may require space near the main water supply, such as a utility room, garage, or under-stairs cupboard. Once installed, maintenance is generally straightforward, with filters usually replaced every 6–12 months depending on water quality and system type.
For homeowners looking for a complete, low-maintenance solution, a whole home water filtration system installation offers one of the most effective ways to upgrade water quality across the entire property. Many homeowners searching for water filtration systems for homes in London are often dealing with hard water issues such as limescale and chlorine taste.
For homeowners trying to decide between the most common installation options, it’s helpful to compare whole-house and under-sink systems in more detail.
Choosing the Right Water Filtration System for Your Home
Choosing the right water filtration system for your home depends on a combination of factors, including your water quality, household size, budget, and what you want to achieve from filtration. Not every home requires the same solution, which is why understanding your specific needs is essential before making a decision.
One of the first considerations is water quality. Homes in hard water areas such as London may benefit more from whole home water filtration systems, as these help reduce limescale, chlorine, and sediment across the entire property. In contrast, homes with fewer water quality issues may only need a targeted under-sink system for drinking and cooking water.
Household size and water usage also play an important role. Larger families or high-usage households typically benefit from whole-house systems, as they ensure every tap, shower, and appliance receives filtered water. Smaller households or individuals may prefer under-sink or point-of-use systems, which focus on specific outlets without the need for full-property installation.
Your budget will also influence the best choice. Under-sink systems are generally more affordable and easier to install, while whole home water filtration systems require a higher upfront investment but provide comprehensive coverage and long-term benefits across the entire property.
It’s also important to understand when filtration is essential versus optional. In areas with noticeable limescale, chlorine taste, or older plumbing systems, filtration can significantly improve water quality and protect appliances. However, in areas with relatively good water quality, a full system may not always be necessary, and a simpler solution could be sufficient.
Ultimately, the best approach is to match the system to your home’s specific needs rather than choosing based on popularity alone. This is why professional advice is often recommended when selecting between different water filtration systems for homes, ensuring you invest in the right solution for both performance and long-term value.
Whole-House vs Under-Sink Water Filtration Systems: Which Is Right for Your Home?
| Feature | Whole-House Filter | Under-Sink Filter |
| Coverage | Entire home (all taps and appliances) | Single tap (usually kitchen) |
| Use | Best for families, high water use, poor water quality | Best for drinking and cooking water only |
| Installation cost | Higher | Lower |
| Space Requirement | Requires space near main water supply | Fits under kitchen sink |
| Maintenance | May involve more complex servicing | Simpler, easier to replace filters |
Consider your water quality, household size, and budget to choose the right option.
Do UK Homes Really Need Water Filtration Systems?
While UK tap water is generally safe, it still contains treatment chemicals, sediment, and limescale, especially in hard water regions. Our plumbers will tell you how homes in London and the South East are particularly affected and how filtration systems work wonders in addressing these issues and provide added peace of mind too.
Common Myths About Water Filtration
"Tap water is perfectly safe." True, but it may still contain trace contaminants and chlorine.
"Bottled water is better." Often, bottled water is just filtered tap water.
"Filters remove all minerals." Most systems preserve essential minerals.
"Filtration is expensive." Costs are offset by long-term savings and fewer repairs.
Things to Consider Before You Buy a Water Filter
With health and wellness trending across social media, water filters are becoming increasingly popular—especially among young professionals. One of the most talked-about options, and one that our plumbers are increasingly coming across, is Water2, co-owned by survival expert Bear Grylls. The brand uses an advanced activated carbon system and has built a reputation for being both stylish and health-aware. But just because it’s trending, doesn’t mean it’s the right fit for every home.
People seem to be just buying it (Water2), but when our plumbers turn up, the homeowner often has no space for it—and all sorts of problems.
Things a homeowner needs to consider before buying any water filter is: space in the cupboard or wherever you’re proposing to put it; check pipework that you’ve got is suitable and accessible; and make sure there is a cold water pipe to connect onto. If that cold water pipe is all hidden behind kitchen units and you’ve got to cut out half of them to get to it, you might want to consider whether or not it’s worthwhile.
The rising popularity of filters like the Bear Grylls-backed Water2 is heavily driven by health trends, they accompany the adverts with lots of information about chemicals in water and how bad they are for you—so people become obsessive about it. Young people nowadays are quite excessive about their health and looking after themselves.
With so many options on the market, it’s vital to think about practicalities as well as popularity. Before you buy, ask:
- Do I have enough space to install this filter?
- Is my existing pipework suitable?
- Will installation be straightforward, or will it require major alterations?
- Am I choosing the best filter for my actual water needs—or just what’s trending online?
Don’t forget, Maintracts is here to help you choose and install a system that fits your home and lifestyle, without the guesswork.

Frequently Asked Questions About Water Filtration Systems
A whole home water filtration system is a point-of-entry solution that treats all water entering your property before it reaches any tap, shower, or appliance. Unlike under-sink filters that only treat water at a single outlet, a whole home water filtration system is installed at the mains water supply so that every water source in the property is filtered.
These systems are commonly used in homes where consistent water quality is important throughout the entire property. They help reduce chlorine, sediment, and limescale, making them a popular choice for households in hard water areas such as London.
The best domestic water filtration systems in the UK depend on your water quality, household size, and what you want to improve.
For many homes, a combination of solutions works best:
Whole-house water filtration setups are ideal for treating all incoming water and reducing limescale, chlorine, and sediment across the property.
