Common questions before you buy
Everything people usually ask about fitting and filtering. Still unsure? Call 0116 278 3334.
How long does the filter last and what does it cost to run?
Each filter lasts3 years or 40,000 litres, whichever comes first, so no yearly cartridge changes. That works out far cheaper than bottled water or filters swapped every few months.
Will it fit under my sink?
The System 40 fits the vast majority of UK under-sink setups and connects to a standard cold feed. If space is tight, give us a call before ordering and we'll confirm it'll work for you.
What does it actually remove?
Multi-stage silver-impregnated carbon filtration reduces chlorine, lead, pesticides, hormones, antibiotics and the odours that affect taste. Want fluoride reduced too? Choose the 40 Fluoride Reduction Media option above.
How hard is the installation, really?
It's a genuine DIY job for most people. The push-fit connectors mean no plumbing skills and no plumber. Most customers have it running in minutes, and there's a fitting video on this page. EMWC Smart Fit support is on hand if you get stuck.
Will it reduce my water pressure or flow?
It's designed to deliver filtered water on demand straight from your tap, so day-to-day use feels normal.
