Strengths and trade-offs
Franke Instante
What we like
- Current Franke 4-in-1: boiling, filtered, hot and cold from one tap
- Built-in filtration and tank included, no separate module needed
- Genuine 100°C boiling water
- Three-year Franke guarantee on the working parts, one year on the tap finish
Watch out for
- Filtered cold water, not actively chilled
- Narrow finish range at launch
- Newer model with a thinner independent-review record than the Omni it replaces
- Guarantee depends on the filter being replaced at the interval Franke specifies, and Franke asks for proof of cartridge purchases before it pays out
