Why Choose DWRO® 1812-100

🔬

Aquaporin Inside® Biomimetic Technology

Nature's own water channels — aquaporin proteins — embedded in a thin-film composite matrix. These biological channels selectively transport water molecules while rejecting dissolved salts, organics, and microorganisms with less energy than conventional polyamide membranes.

Low-Pressure, Line-Pressure Compatible

The DWRO® 1812-100 is designed for standard residential line pressure — no booster pump required for most installations. Achieves rated 100 GPD at just 100 psi (6.9 bar).

🏠

Drop-In Replacement

Standard 1.8″ format fits all conventional point-of-use and commercial RO membrane housings. No adapters, no modifications — unscrew the old element, insert the DWRO.

📦

Dry Element — Ready to Ship

Unlike wet-tested membranes that require preservative solutions and extended flushing, DWRO elements ship dry — no glycerin, no chemical disposal, minimal commissioning time.

💧

Great-Tasting Drinking Water

DWRO membranes are purpose-engineered for drinking water — the biomimetic channels produce clean, fresh-tasting permeate without the 'flat' character sometimes associated with conventional RO. Ideal for direct consumption, coffee, tea, and cooking.

How Customers Use DWRO® 1812-100

01

Under-Sink Drinking Water

Install the DWRO® 1812-100 in a standard under-sink RO system for great-tasting drinking water at the kitchen tap. The 1.8″ format fits all conventional point-of-use membrane housings.

02

Apartments & Small Homes

Serve a single-family apartment or small home with 100 GPD of high-quality permeate. Pairs with a standard 3- or 4-stage pre-filtration setup for complete point-of-use treatment.

03

Post-RO Revitalisation with The Heart

RO permeate is clean but structurally 'flat'. Install The Heart after your DWRO system to restore natural water structure — the combination gives you the purest, most vital drinking water possible.

DWRO® 1812-100 + The Heart

RO permeate is demineralised and structurally 'flat' — the membrane strips everything, including water's natural structure. Install The Heart after your DWRO system to revitalise the permeate back into structured, living water. Especially recommended for drinking water systems where taste and vitality matter.
