Notturno Filter Head — Duplex
Tax included where applicable. Delivery and installation arranged by your concierge.
NAVERQIO Water — the ingredient nobody tastes and everyone drinks
Most machines die of water, slowly and expensively. The Notturno is the cheap insurance done properly — supply and post-filter gauges, litre metering, and a schedule printed to your actual daily draw.
Espresso water is designed, not filtered by luck. Our systems pair carbon and membrane stages with mineral dosing, so hardness and alkalinity land where boilers live long and cups taste sweet — typically 40 to 80 ppm with buffered alkalinity. Heads are brass, housings are pressure-rated far beyond mains, and every cartridge change is a hand-turn, not a plumber's visit.
Design & Craft
- Metered heads count litres so cartridge changes are facts, not guesses
- Push-fit connections a careful owner installs in an afternoon
- Cartridge schedules printed to your daily draw
- Pressure-rated housings far beyond mains; leak trays and shutoffs standard
- Scale, chlorine and taste stages matched to espresso duty

Care
Change cartridges by litres, not months — the meter on the head counts for you. Sanitise housings at each change, verify TDS quarterly with the included meter, and re-check the bypass setting whenever the machine or the menu changes.
Questions, Answered
Can I install it myself?
Filter heads and cartridge systems are hand-tight and push-fit — most customers do. RO and station installs are included in CZ delivery for orders above the noted threshold.
Does RO waste much water?
Modern membranes with pressure assistance run far tighter than the old horror stories; drain ratios are in the specification, and drain-water heat is negligible at espresso volumes.
