AERA FLOW
A full, focused spray from a precision shower plate.
Fine triangular outlets distribute water across the spray plate for a satisfying shower with efficient flow.
How Aera Flow worksRadiance and Nourish recorded a mean flow rate of 5.0 L/min when tested to AS/NZS 3662:2013 by Singapore Laboratory Services.
What the plate does
How Aera Flow shapes the shower spray
Fine triangular spray openings.
Aera Flow uses triangular openings to distribute water across the spray plate and shape a broader spray.
Precision openings measuring about 0.3 mm.
Each opening is about 0.3 mm across, creating fine, focused streams across the spray area.
Accessible for routine rinsing.
The showerhead opens by hand, giving you access to the spray plate for routine rinsing and scale care.
The numbers
Aera Flow measurements and test scope
Opening size
0.3 mm. About a tenth of a conventional spray hole.
Pressure
Up to 50% more than a conventional plate. Manufacturer tested.
Flow rate
5.0 L/min on Radiance and Nourish. Top band, and 30 to 50% below a standard head.
Made in
Korea, on Water Lab Co.'s platform. Patent held there.
Fitted to
Radiance, Nourish, Aura. Not the Universal, which has no plate.
Flow rate tested to AS/NZS 3662:2013 by Singapore Laboratory Services, report 22608188-CLC, 19 March 2026.
Flow rate, test conditions
5.0 litres a minute is the mean across 1.5, 2.5, 3.5, 4.5 and 5.0 bar, measured under clause 5.1 and appendix B of the standard. The laboratory is SAC-SINGLAS accredited and the result sits in the top efficiency band of 5 litres a minute or less.
The report covers SUH-RAD-CHR, SUH-RAD-BLK and SUH-NOR-CHR. Aura's flow figure is the manufacturer's own and is not covered by it.
Pressure-data scope
The pressure comparison comes from manufacturer testing. The independent SLS report measures flow rate, not pressure.
The Korean chlorine and media-hygiene certificates apply to filter media and do not measure Aera Flow spray performance.
Standing under it
Broad coverage with a focused feel
Aera Flow distributes water through fine triangular openings across the spray plate.
The result is a full spray pattern designed to feel satisfying without relying on a harsh, concentrated jet.
Water is spread more evenly across the spray area.
The water path through the head.
The other half
Aera Flow shapes the spray. SUHAE filtration treats the water.
Published chlorine result
Residual chlorine was not detected at each test interval from 1,000 to 6,000 litres under the published conditions.
See certificate IW-230133 for the test method, sample and stated volume range.
Ceramic media hygiene test
The test recorded a 99.9% reduction in E. coli and S. aureus on the ceramic media after 24 hours of static contact.
The result applies to the media itself, not outgoing shower water.
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 cover the filter. Neither says anything about the spray plate.
Before you buy
What to expect from Aera Flow
How does Aera Flow change the spray?
Fine triangular openings distribute the water across a broad spray area for a full, focused feel.
The pressure comparison comes from manufacturer testing.
The independent laboratory report measures mean flow rate at 5.0 L/min for Radiance and Nourish.
Does the smaller opening size reduce flow?
Radiance and Nourish recorded a mean flow rate of 5.0 L/min while maintaining a full spray pattern.
The spray feel depends on outlet geometry, household pressure and how evenly water is distributed across the plate.
Actual shower performance depends on the installed water supply and product configuration.
Questions
Frequently asked questions about Aera Flow
Does the Suhae Universal have Aera Flow in it?
No. The Universal is an attachment that sits between your plumbing and the shower head you already own, so it filters the water and leaves the spray exactly as it is. It has no spray plate of its own, which is why no pressure figure and no flow figure on this page apply to it.
Aera Flow is the plate inside Suhae's own heads. The Radiance is the one we point most people at.
Does the plate filter anything by itself?
No. Aera Flow shapes the spray. Purea Core and Vitae Infusion provide the filtration stages inside compatible SUHAE shower products.
Will openings that small clog?
Mineral scale can build up on any showerhead. Compatible SUHAE heads open by hand so you can rinse the spray plate as part of routine care. Hard-water areas may require more frequent cleaning.
Which Suhae products carry the plate?
Radiance, Nourish and Aura. The flow rate figure above was measured on the Radiance and Nourish handshowers only. Aura's figure is the manufacturer's own.
