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.
