Enjoy delicious filtered, chilled and sparkling from your kitchen tap - welcome to Grohe Blue Home Duo

Bottled water is great for the table, but it can be a hassle to carry and creates plastic waste. There is a better way - installing the Grohe Blue Home Duo, a more convenient and eco-friendly solution offering the same great taste and even higher quality than bottled water! The great value Grohe Blue Home Duo starter kit has everything you need to enjoy the pure pleasure of filtered, chilled or carbonated water. You can even select sparkling or a semi-sparkling option. And with a Blue Home Duo tap you get all the benefits of a well-designed classic Grohe kitchen tap too. The kit combines a Grohe Blue single-lever tap and a low-energy home cooler unit, containing the filter and CO2 bottle for carbonization. The cooler unit fits into any cabinet over 30cm wide and both the filter and 425g CO2 bottle are easy to remove and replace. The contemporary U-shaped spout and slim body conceal separate inner water ways for filtered and non-filtered water. The lever handle provides standard water, but to activate the filter, chilled or sparkling function you simply press the illuminated LED push button. It's as easy to use as your smartphone and the LED display alerts you when to change the cartridge. Created with Grohe's elegant lines, this kitchen mixer also has a long-lasting matt Grohe Super Steel finish and durable Silk Move internal mechanism for easy handling. Plus, with no external piping needed and everything in the kit ready to go, it only takes 30 minutes to install. Grohe Blue Home Duo - a new level of kitchen convenience!
