A fuller spray from a plate with holes a tenth the usual size.
Fine triangular openings spread the water across the whole plate, so a New Zealand shower feels full while using less water each minute.
See how the plate worksTested to AS/NZS 3662:2013, the Australian and New Zealand Standard: Radiance and Nourish ran at a mean 5.0 litres a minute (Singapore Laboratory Services).
What the triangular openings do to your water
Triangles, not round holes.
Each opening is triangular, which spreads the water wider across the plate and gives a broader spray.

Openings about 0.3 mm across.
At roughly 0.3 mm, each opening sends out a fine, focused stream across the spray area.

Opens by hand for a rinse.
Twist the head apart and rinse the plate under the tap. No tools, and it takes a minute.
The Aera plate, measured
Flow tested to AS/NZS 3662:2013, the standard New Zealand and Australia share, by Singapore Laboratory Services. Report 22608188-CLC, 19 March 2026.
How the flow test was run
The 5.0 litres a minute is the average across 1.5, 2.5, 3.5, 4.5 and 5.0 bar, under clause 5.1 and appendix B of the standard. The lab is SAC-SINGLAS accredited, and the result sits in the top band of 5 litres a minute or less.
The report names SUH-RAD-CHR, SUH-RAD-BLK and SUH-NOR-CHR. Aura's flow figure is the manufacturer's own.
Where the pressure figure comes from
The pressure comparison is the manufacturer's testing. The SLS report measures flow rate.
The KEWI chlorine and KIFA media certificates cover the filter inside the head; the plate has its own figures above.
Wide coverage, with a focused feel
The triangular openings spread water across the full face of the plate.
You get a full spray pattern that feels satisfying without one hard, concentrated jet.
The water lands evenly, edge to edge.
How the water travels through the head.
The plate shapes the spray. The filter takes the chlorine out of New Zealand town water.
Chlorine, measured
Residual chlorine was not detected at any test interval from 1,000 to 6,000 litres under the published conditions. Free chlorine, the kind New Zealand suppliers use.
Certificate IW-230133 has the method, the sample and the full volume range.
The filter media
The test recorded a 99.9% reduction in E. coli and S. aureus on the ceramic media after 24 hours of static contact.
The filter media is tested to resist bacteria growing inside the cartridge.
Chlorine: Korea Environment and Water Works Institute, certificate IW-230133, 24 April 2023. Media hygiene: Korea Far Infrared Association, certificate KFIA-110, January 2023. Both certificates cover the filter.
What Aera Flow means for your shower
What will I notice under it?
A broad, even spray from the triangular openings, with a full, focused feel.
The pressure comparison is from the manufacturer's testing.
The independent lab measured Radiance and Nourish at a mean 5.0 L/min.
Will smaller openings mean less water?
Radiance and Nourish measured a mean 5.0 L/min with a full spray pattern, tested to the standard New Zealand uses.
How the spray feels comes down to the shape of the openings, your household pressure and how evenly the plate spreads the water.

Aera Flow, asked and answered
Is Aera Flow in the Suhae Universal?
No. Universal sits between your plumbing and the head you already own, so it filters the water and your own head shapes the spray. It has no plate of its own, so the pressure and flow figures on this page are for the heads that do.
Aera Flow is built into Suhae's own heads. The Radiance is where most people start.
Will it fit a New Zealand shower?
Radiance and Nourish screw onto the standard ½-inch hose thread used across New Zealand, by hand. Send a photo on WhatsApp if your setup is unusual.
Will openings that small block up?
Any shower head can collect scale. Most New Zealand town water is soft, and the head opens by hand when the plate needs a rinse.
Does it work on Christchurch or Wellington water?
Yes. Both cities chlorinate with free chlorine, which is what the filter behind the plate was tested on. The flow figure above covers Radiance and Nourish; Aura's is the manufacturer's own.
