Overview
What filter housings and spares do
A filter housing holds the cartridge that protects your RO plant, softener, process line or appliance. Picking the wrong size, material or pressure rating leads to bypass, leaks or frequent changes.
Greenly supplies single and multi-cartridge housings, jumbo (Big Blue) housings, stainless steel bag and cartridge housings, UV housings, spin-down filters and FRP pressure vessels, along with the cartridges and spares to keep them running.

Questions, answered
FAQs about Filter Housings & Spares
Still unsure? Ask us directly or call +91 95000 55565.
What micron rating should I use?
For RO pre-filtration 5 micron is common; sediment pre-filters often use 20 to 50 micron. The right rating depends on your water and the equipment you protect.
When should I choose a stainless steel housing?
Use SS housings for higher pressures, hot water, hygienic applications or where the housing must last outdoors.
Can you make custom housings?
Yes. We make customised housings for special flow rates, cartridge counts and connections. Share the duty conditions and we will propose a design.
Do you supply RO spares?
Yes. Membranes, membrane housings, pumps, cartridges, valves and other RO spares are available. Share your plant details for a matching list.
How often should cartridges be changed?
When pressure drop across the housing rises or flow falls noticeably. In many systems that is every one to three months, but water quality decides.
What is an FRP vessel used for?
FRP pressure vessels hold sand, carbon, iron removal media or softener resin. They are corrosion resistant and come in standard sizes with top or side openings.
