Product Advantages
HYNAMO’s 50G and 75G reverse osmosis membranes offer a compelling balance of high purification efficiency, cost‑effectiveness, and long‑term reliability, making them an ideal choice for daily drinking water needs in Chinese households.
Key Advantages
-
Superior purification for safe drinking water
With a filtration precision of 0.0001 microns, these membranes effectively remove heavy metals, bacteria, viruses, and other harmful contaminants, maintaining a stable desalination rate of over 97%. Certain models (e.g., GK1812‑75) further enhance salt rejection through optimised membrane layer structures. -
Stable performance and extended service life
Designed with strong anti‑fouling properties, the membrane surface is treated to increase hydrophilicity, reducing scale and particle adhesion. This enables a typical service life of 24 to 36 months. Additionally, the output flow remains consistent, avoiding the fluctuations common in lower‑quality products. -
Excellent cost‑effectiveness
While delivering performance comparable to leading international brands, Haina membranes are priced at roughly half the cost of imported equivalents – a highly economical solution for quality‑conscious consumers. -
Water‑saving and environmentally friendly
By incorporating advanced low‑wastewater technology, these models can reduce brine discharge by up to 67% compared to conventional RO systems, contributing to greener water usage. -
Easy installation and broad compatibility
Manufactured in standard sizes (e.g., the 1812 series), they are straightforward to install or replace and are widely compatible with most household water purifiers on the market.
Application Scenarios
Key Applications
-
Under‑sink water purifiers – the most common use, providing direct‑drinking water, cooking, and soup‑making water for families.
-
Whole‑house water purification systems – serving as the core filtration unit to ensure safety throughout the home.
-
Community and commercial drinking water dispensers – used in public drinking fountains, office water stations, and light commercial systems.
-
Other small‑scale pure water equipment – also suitable for hospitals, laboratories, and other settings requiring high‑quality purified water.
In summary, HYNAMO’s 50G and 75G RO membranes strike an excellent balance between purification efficacy, durability, and affordability – making them a reliable choice for upgrading or replacing filters in residential water treatment systems.
