RO Water Purifier Systems
Reverse Osmosis (RO) water purifiers use a semi-permeable membrane to remove dissolved impurities, heavy metals (lead, arsenic, fluoride), bacteria, viruses, and chlorine from drinking water. Our RO systems deliver clean, safe water with TDS as low as 20–50 ppm, ideal for areas with hard water or high dissolved solids. Available in 5-stage to 9-stage purification with digital TDS display, auto shut-off, and long-life membranes.
- Removes dissolved salts, heavy metals, fluoride, arsenic, nitrates
- 99.9% bacteria and virus removal with post-UV or post-UF stage
- Digital TDS meter display for real-time water quality monitoring
- Auto shut-off when tank is full — saves water and electricity
- Long-life 75 GPD / 100 GPD RO membrane (1–2 year life)
- Food-grade materials — BPA-free tank and tubing throughout
- 1-year warranty with free service and filter replacement reminders
UV Water Purifier
Ultraviolet (UV) purifiers use high-intensity UV-C light (254 nm wavelength) to deactivate the DNA of bacteria, viruses, and cysts — rendering them harmless without adding any chemicals to water. UV purification is the safest, fastest, and most chemical-free method of water sterilisation for homes. Best suited for low-TDS municipal water supply (below 200 ppm) where the primary concern is microbial contamination.
- Destroys 99.99% of bacteria, viruses, and cysts using UV-C light
- No chemicals added — natural, safe purification process
- Instant purification — no waiting or storage tank needed
- UV fail alarm alerts when lamp intensity drops below safe level
- Pre-filter sediment cartridge removes turbidity and particles
- Activated carbon filter removes chlorine, odour, and taste issues

RO + UV + UF Multi-Stage Purifier
The most comprehensive domestic water purification solution — combining three powerful technologies in one unit. RO removes dissolved solids and heavy metals; UV sterilisation eliminates all microbial threats; UF provides a final physical barrier to remove any remaining suspended particles. Suitable for all water sources including municipal, borewell, tanker, or river supply.
| Stage | Technology | Function |
|---|---|---|
| 1–2 | Sediment + Carbon Pre-filter | Removes mud, sand, chlorine, odour |
| 3 | RO Membrane (75/100 GPD) | Removes TDS, heavy metals, salts |
| 4 | UV Lamp (UV-C 254nm) | Kills bacteria, viruses, cysts |
| 5 | UF Hollow Fiber Membrane | Removes remaining particles & colloids |
| 6 | Mineral / Alkaline Cartridge | Adds Ca, Mg, K back to purified water |
| 7 | Post Carbon Polish | Final taste & odour improvement |
- Works on all types of water — municipal, borewell, tanker supply
- Handles input TDS up to 2000 ppm effectively
- Mineral cartridge ensures essential minerals in output water
- Digital display: TDS, filter life, UV lamp status
- Energy saving mode and auto shut-off function
Alkaline Water Purifier
Alkaline water purifiers go beyond standard RO filtration by using a special mineral cartridge (containing tourmaline, maifan stone, and alkaline minerals) to raise the pH of purified water to between 8.0 and 9.5. Alkaline water helps neutralise excess acidity, improves hydration, and provides antioxidant benefits. Our systems combine full RO+UV+UF purification with alkaline remineralisation.
- Raises water pH to 8.0–9.5 using natural mineral stones
- Negative ORP (Oxidation Reduction Potential) — antioxidant properties
- Adds back essential minerals lost during RO filtration
- Includes full RO+UV+UF purification stages for complete safety
- Suitable for people with acidity, joint pain, and health concerns
- Food-grade alkaline mineral cartridge — safe and certified
Commercial RO Systems (50 LPH – 2000 LPH)
High-capacity RO systems designed for offices, restaurants, schools, hospitals, gyms, and small factories. These systems feature stainless steel or FRP pressure vessels, commercial-grade pumps, and multi-membrane configurations for high-volume purified water output. All systems come with auto-flush controller, low-pressure cut-off, and digital TDS display.
