See what your tap water is really carrying.

TapSmart ChargeFlow cartridge

Water suppliers add chlorine to disinfect tap water, which is what gives it that noticeable taste and smell. TapSmart's activated carbon media is designed to reduce chlorine and its associated byproducts as water passes through the cartridge.

Ageing pipework can carry fine sediment, rust and particulate matter into your tap water. TapSmart's multi-stage cartridge is designed to capture sediment before it reaches your glass, for cleaner, clearer-tasting water.

Lead pipework is still common in older UK homes, and boiling water doesn't remove lead — it can concentrate it. TapSmart's filtration media is designed to reduce heavy metals such as lead as water passes through the cartridge.

PFAS, often called 'forever chemicals', don't break down naturally and have been detected across UK water supplies. TapSmart's ChargeFlow™ cartridge is designed to target PFAS as part of its multi-stage activated carbon filtration.

Microplastics can enter the water supply from ageing infrastructure and packaging, and are increasingly found in tap water testing. TapSmart's multi-stage filtration is designed to capture microplastic particles as water passes through the cartridge.

Run-off from farmland can carry pesticide and herbicide residues into the water network. Activated carbon, the core filtration media inside TapSmart's cartridge, is a well-established method for adsorbing organic pesticide residues from water.

Volatile organic compounds and hydrocarbons can enter tap water from industrial run-off or ageing pipework. Activated carbon filtration — the technology inside TapSmart's cartridge — is one of the most established methods for adsorbing VOCs from drinking water.

Chlorine, sediment and trace organic compounds are the main reasons tap water can taste or smell 'off'. Multi-stage activated carbon filtration, like the media inside TapSmart's cartridge, is specifically effective at improving taste and odour.

Beyond chemical contaminants, tap water can carry bacteria and other microorganisms, particularly after supply interruptions. TapSmart includes patented UV protection alongside its carbon cartridge, adding a layer designed to target microorganisms as water passes through the unit.

TapSmart is designed to fit the vast majority of standard kitchen taps straight out of the box, and includes a set of universal adapters for less common fittings. If you're ever unsure, our support team is happy to check compatibility with you before you order.
No. TapSmart's filtration media is designed to reduce common contaminants such as chlorine, sediment and heavy metals, while leaving beneficial minerals like calcium and magnesium in your water.
Water passes through multiple filtration stages inside the cartridge before it reaches your glass, capturing sediment and reducing unwanted tastes and odours, so what comes out the other end is cleaner, better-tasting tap water.
Most customers notice little to no difference in pressure. The filter is engineered to maintain a steady flow rate, though homes with very low starting pressure may notice a slight change.
Installation typically takes around 10 minutes, with no plumber or specialist tools required. Everything you need is included in the box, along with step-by-step instructions.
