RO Water Filters in Hyderabad

Sediment Filters (Pre-Filters)

We offer three types of sediment filters, each suited for different water conditions in Hyderabad:

PP Spun / Melt-Blown Filters:

Available in 1, 5, and 10-micron ratings, made from food-grade polypropylene. Ideal for removing fine particles like sand, dust, and rust from borewell and tanker water. Widely used in Kukatpally, LB Nagar, and Miyapur.

String Wound Sediment Filters:

These have a higher dirt-holding capacity and are best suited for older apartments and pipelines prone to rust and silt. Available in 5 and 10 microns.

Pleated Filters:

Designed for higher flow and extended surface area. Recommended for clinics, cafés, and offices in areas like Hitech City and Madhapur with higher water usage.

These filters help protect the RO membrane by stopping physical particles from clogging later stages.

Activated Carbon Filters (GAC & CTO)

Carbon filters are crucial for improving water taste and protecting the RO membrane from chlorine damage:

• Granular Activated Carbon (GAC) Filters:
  Use high-iodine value carbon (900–1100 IV) derived from coconut shells. Ideal for municipal water areas such as Ameerpet and Banjara Hills to remove chlorine, odour, and organic impurities.
• CTO (Carbon Block) Filters:
  These use compressed high-density carbon blocks for finer filtration and better contact time. Preferred in premium RO setups and food-related use cases for taste enhancement and chlorine control.
  Using high-quality carbon filters is key to extending membrane life and preventing chemical fouling.

RO Membrane Filters

The RO membrane is the most critical filter for reducing TDS, hardness, and dissolved contaminants:

• Domestic RO Membranes:
  Available in 50, 75, 80, and 100 GPD capacities. Suitable for home and small office purifiers in Hyderabad where TDS varies from 300 to 1200 ppm. TFC (thin-film composite) material ensures up to 97% TDS rejection.
  
• High-Flow RO Membranes:
  Designed for cafés, shared PG systems, and commercial setups needing higher output. Capacities range from 150 to 300 GPD. Works best with upgraded pumps and proper filter housing.
  All membranes supplied by Greenly are tested in Hyderabad conditions for stable output and longer life

Post-Carbon and Mineral / Alkaline Filters

These filters refine water quality and restore taste after purification:

• Inline Post-Carbon Filters:
  Used after the RO tank for final polishing. These remove residual odours and improve the mouthfeel of water. They’re made from coconut shell carbon and come with 1/4” push-fit connectors for easy installation.
  
• Mineral / Alkaline Cartridges:
  Add essential minerals like calcium and magnesium, and correct the pH of low-TDS water. Recommended when RO output TDS drops below 50 ppm, common in areas with treated municipal water.
  These filters help make RO water more palatable and health-friendly.
