Will this filter fit my fridge?
Great taste is good. Trusted water is better.
If you already use a fridge filter, this is the quiet under-sink upgrade that makes water look clearer, taste cleaner, and feel right—every day.
Why upgrade (vs tap or a fridge filter)
• Goes beyond taste: reduces dissolved solids (TDS), microplastics and heavy metals that standard fridge filters don’t target.
• Clear in the glass: brighter tea, clearer drinks, fewer chalky marks on glasses and kettles.
• Less faff: dedicated drinking tap—no juggling jugs or guessing change dates.
• Consistent all year: mains water varies by street and season; your water quality doesn’t.
Day-to-day value you’ll notice
• You naturally drink more because it tastes cleaner.
• Lower TDS helps limit limescale in kettles and coffee gear.
• Fewer “emergency” bottled-water runs—more space in the fridge and cupboards.
• Predictable and easy—filters arrive on schedule, so you never forget.

What is reverse osmosis (RO)?
An ultra-fine membrane (0.0001 μm) that removes tiny dissolved contaminants your fridge filter misses—a deeper clean in plain English.

Mini-FAQ
Q: Isn’t tap water already safe?
A: Yes—to legal limits. Those limits still allow tiny amounts that affect taste, clarity and limescale. This is about improving the experience and reducing unnecessary exposure.
Q: What does this add beyond my fridge filter?
A: Fridge filters polish flavour. X Series also reduces dissolved solids, microplastics and heavy metals—hence clearer glasses, brighter tea and slower limescale.
Q: Do I need a plumber?
A: Many customers DIY under the sink; a plumber is optional if you prefer.
Q: What if I cancel the filter plan?
A: You keep the machine. Deliveries simply stop. You can restart any time.
