Strengths and trade-offs
Arno Square 4-in-1
What we like
- £499 RRP delivers 4-in-1 cheaper than most rivals
- 2-stage filtration removes chlorine and heavy metals
- 360° swivel spout handles pot-filling and rinsing
- Child-safe spring-loaded boiling dispense as standard
Watch out for
- 98°C ceiling not true 100°C boiling
- 2.4L tank yields only 7-8 cups before recovery
- Limited independent reviews outside Arno marketing
- Newer brand lacks long-term UK reliability track record
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
