Benefits

Why Choose CLEAR Plus 4040

🔬

Biomimetic Technology

Aquaporin Inside® membranes use protein channels that selectively transport water molecules with lower energy input than conventional RO membranes.

📦

Compact Format

At just 4" × 40", the CLEAR Plus 4040 fits small-scale systems where a full 8040 element would be impractical — pilot plants, research labs, and point-of-entry installations.

✅

NSF 61 Certified

Certified to NSF/ANSI/CAN 61 for use in drinking water applications — commercial kitchens, restaurants, water vending, and small bottling operations.

⚡

Lower Energy Demand

Aquaporin protein channels require less hydraulic pressure than traditional polyamide membranes, reducing pump size and energy consumption per litre of permeate.

Applications

How Customers Use CLEAR Plus 4040

01

Pilot & R&D Plants

The 4040 is the standard format for pilot-scale testing and R&D laboratories. Validate your process with the same Aquaporin Inside® technology before scaling to 8040 production elements.

02

Small Commercial RO

Cafés, restaurants, small hotels, and water vending machines — anywhere that needs ~100 GPD of high-quality permeate from a compact membrane element.

03

Point-of-Entry Residential

Whole-house RO for a single-family home with moderate water demand. Pairs well with The Heart for post-RO water revitalisation.

Perfect Pairing

CLEAR Plus 4040 + The Heart

Pair your CLEAR Plus 4040 with The Heart — our passive water vortex revitaliser. The Heart restructures RO permeate (which is demineralised and 'flat' after reverse osmosis) into structured living water for your home.
