How To Choose The Best Under Sink Water Filter For You
In the UK, even though tap water is typically deemed safe for consumption, a growing number of homes are opting for water filters to guarantee top-notch drinking water. If you’re wary of your tap water’s taste, potential heavy metals, or hard water issues, an under-sink water filter could be your answer.
Understanding UK Water Supply
The water supply in different regions of the UK can vary in quality. Despite rigorous treatment of tap water to remove dangerous substances, it might still possess chlorine, employed for disinfection, and occasionally, heavy metals.
A water quality test, readily available in the UK, can help you understand the specific contaminants in your local water supply.
Types of Under-Sink Water Filters
Activated Carbon Filters: Widely used in the UK, these filters utilise activated carbon to attract and trap contaminants.
They’re particularly effective against chlorine, bad taste, and odour. Carbon filters, especially the carbon block type, can also reduce some heavy metals and bacteria.
Reverse Osmosis Filters: These are becoming increasingly popular in UK homes. The reverse osmosis system pushes tap water through a semipermeable membrane (reverse osmosis membrane) to remove a wide range of contaminants, offering purified water. It’s especially effective against heavy metals and bacteria.
Sediment Filters: Essential for homes in areas with old plumbing, these filters remove larger particles like rust and sand. They’re often paired with other filters to prolong their filter life.
Ultrafiltration System: Using a membrane, this system is effective against bacteria and larger impurities, ensuring clean water flows from your kitchen tap.
Key Considerations for UK Homes
Water Hardness: Many areas in the UK, especially in the South, have hard water. If limescale buildup is a concern, consider a water softener or a filter system designed to handle hard water.
Filter Life & Replacement: Depending on your water usage and the water quality in your area, filter replacement can vary. Ensure you’re aware of the filter life and set reminders for timely replacements.
Flow Rate: UK homes often have varying water pressure. Choose an under-sink water filter system that offers a good balance between filtration efficiency and water flow rate.
NSF Standards: While the NSF ANSI standards are American, they’re recognised globally. Filters that meet these standards have been tested to effectively remove specific contaminants.
Healthy Minerals: Some filtration systems, like reverse osmosis, might remove beneficial minerals. Opt for systems that reintroduce these minerals post-filtration or consider water filter pitchers that ensure mineral retention.

Frequently Asked Questions About Under Sink Water Filters
Can Water Filters Reduce TDS (Total Dissolved Solids)?
Yes, certain water filters, especially reverse osmosis systems, can effectively reduce TDS Reverse osmosis (RO). Because they utilise a semi-permeable membrane that filters out a wide range of contaminants, including salts, minerals, and other dissolved solids.
While other filtration methods like activated carbon filters can remove specific contaminants, they may not significantly reduce overall TDS levels.
Is It Cheaper To Buy Bottled Water Or Filter?
In the UK, using water filters to filter tap water is significantly cheaper than buying bottled water. Most bottled water is essentially filtered tap water packaged in plastic bottles.
The cost of the actual water in bottled water makes up only about 10% of its price. On the other hand, a litre of tap water, whether metered or paid for through a fixed water tariff, costs about 0.1p.
By drinking from the tap and using a filter, consumers can save a substantial amount over the years compared to buying bottled water.
What Are The Disadvantages Of Under Sink Water Filters?
Under-sink water filters are designed to both elevate water flavour and filter out pollutants. However, they also come with certain disadvantages:
Installation Complexity: They often require a more complex installation process compared to countertop filters. Engaging a professional might be needed, which could increase the overall cost.
Maintenance: Regular maintenance and filter replacements are necessary to ensure the system functions effectively. Neglecting this can lead to reduced filtration efficiency.
Space Consumption: Even though they are designed to save countertop space, they can take up significant space under the sink, potentially limiting storage.
Initial Cost: The upfront cost of purchasing and installing an under-sink water purifier can be higher than other types of water filters.
Limited Filtration Scope: They only purify the water from the sink where they are installed. If you want purified water from other sources in your home, additional systems or filters would be required.
Potential for Leaks: If not properly installed or maintained, there’s a risk of leaks, which can lead to water damage under the sink.
Waste Water: Some under-sink systems, especially reverse osmosis systems, produce wastewater. This means that for every gallon of purified water, a certain amount of water is wasted.
Removal of Beneficial Minerals: Some systems might strip water of beneficial minerals like calcium and magnesium, which are essential for health.
Cost of Replacement Filters: Continual filter replacements can become a notable expense over time, especially if the system uses several filters or they need changing often.
Limited to Cold Water: Most under-sink systems are designed to filter cold water only. If you need filtered hot water, you might need a separate system or solution.
