We compare jug filters for chlorine from £29, under-sink chlorine filters from £59, and explain which certifications guarantee real chlorine reduction — not just marketing claims.
Quick Answer: Best Chlorine Taste Filters
Best Budget: BRITA MAXTRA PRO jug (£29.99) - 95%+ chlorine reduction
Best Certified Pitcher: LifeStraw Home Glass (£65) - NSF 42 + removes bacteria, microplastics, lead
Best Value: Waterdrop 10UA under-sink (£59) - 97% chlorine removal, NSF 42 certified
Best Premium: Waterdrop G3P600 RO (£399) - 99.9% removal of chlorine + everything else
Why Does UK Tap Water Taste Like Chlorine?
UK water companies add chlorine to kill harmful bacteria - it's what makes our tap water safe to drink. The legal limit is 0.5mg/L, but even at much lower concentrations, many people can detect the taste and smell.
Why Some Areas Taste Worse
Homes near water treatment plants often have stronger chlorine taste because the chemical hasn't had time to dissipate. Areas at the end of distribution networks typically have lower chlorine levels.
While chlorine at UK levels is considered safe, it can react with organic matter to form disinfection byproducts (DBPs) like trihalomethanes. These are linked to health concerns with long-term exposure. A good carbon filter reduces both the chlorine AND these byproducts.
Best Filters for Chlorine Taste (Tested & Certified)
BRITA MAXTRA PRO All-in-1
£29.99
The classic choice for chlorine removal. BRITA's activated carbon filters reduce chlorine taste by 95%+. No installation needed - just fill and pour. Each filter lasts about 4 weeks.
LifeStraw Home Glass Water Filter Pitcher
£64.95
If you want a pitcher that does more than just chlorine, this is it. NSF 42 certified for chlorine taste, but the real story is what else it removes — a 0.2-micron hollow-fibre membrane catches bacteria and microplastics, while the carbon + ion exchange stage handles lead, PFAS, and mercury. Triple certified (NSF 42, NSF 53, NSF P231). The glass body means no microplastic leaching from the container itself.
Honest note: More expensive than BRITA and slower to fill (gravity-fed through a membrane). Carbon filter needs replacing every 2 months (~£15). But if chlorine taste is just one of your concerns and you also worry about microplastics or lead, this is the only pitcher that genuinely addresses all three.
Waterdrop 10UA Under Sink Filter
£59.48
NSF 42 certified - independently tested to reduce chlorine taste and odour. Installs in 3 minutes under your sink. No more refilling jugs - just turn on the tap for clean, great-tasting water.
Waterdrop G3P600 Reverse Osmosis
£399
If you want to reduce a wide range of contaminants — not just chlorine but also lead, PFAS, microplastics, and more — this tankless RO system is a top choice. Certified to reduce chlorine plus broad contaminant reduction.

Frequently Asked Questions
Why does UK tap water taste like chlorine?
UK water companies add chlorine to kill bacteria and make water safe to drink. The legal limit is 0.5mg/L, but even at lower levels many people can taste it. Chlorine taste is strongest in areas near water treatment plants.
Do all water filters remove chlorine taste?
Most carbon-based filters effectively reduce chlorine taste and smell. Look for NSF 42 certification which specifically tests for chlorine reduction. Basic sediment filters do NOT reduce chlorine — you need activated carbon.
How long does it take for a filter to remove chlorine taste?
The effect is immediate. As soon as water passes through an activated carbon filter, 95-99% of chlorine is removed. You'll notice the difference with your first glass of filtered water.
Is chlorine in tap water harmful?
At UK legal levels (up to 0.5mg/L), chlorine is considered safe. However, chlorine can react with organic matter to form disinfection byproducts (DBPs) like trihalomethanes, which are linked to health concerns with long-term exposure. Filtering reduces both chlorine and many DBPs.
A Simple Guide to Which Filter Type Usually Suits Which Concern
A simple guide to which filter type usually suits which concern.
Jug Filters
Typical price: £20-40Best for improving chlorine taste and odour, with no installation needed.
Under-Sink Carbon Filters
Typical price: £80-150A good middle-ground option for better taste, odour, sediment, and some chemical reduction.
Multi-Stage Under-Sink Systems
Typical price: £150-300Designed for broader reduction, but performance varies by model and certification.
Reverse Osmosis Systems
Typical price: £200-400Best for broader contaminant reduction, including concerns about lead, PFAS, fluoride, and microplastics.
Whole-House Systems
Typical price: £500-2000+Best for protecting appliances and treating water throughout the home, rather than just at one drinking tap.
Most UK homes do well with a simple under-sink carbon filter or a reverse osmosis system, depending on the concern. If you are worried about lead pipes or broader contaminant reduction, start by comparing certified under-sink and RO options carefully.
