Overview of Dolphin water purifiers

Dolphin water purifiers are compact wall-mounted RO systems available through regional dealers and distributor networks across India. Dolphin purifiers use RO+UV+UF purification with optional antioxidant alkaline and mineral booster cartridges on select models. Units carry food-grade ABS plastic bodies, 7 to 12 L storage tanks, 80 GPD RO membranes, auto shut-off, LED indicators, and a 1-year warranty. Dolphin purifiers are primarily marketed in South India, Maharashtra, and Gujarat through local water treatment dealers and regional distributors.

Key features and specifications of Dolphin water purifiers

Dolphin water purifiers deliver a practical set of features for budget-conscious buyers seeking reliable multi-stage purification. Here is what the range consistently offers.

  • RO+UV+UF multi-stage purification: Dolphin purifiers combine reverse osmosis for dissolved solid removal, UV for biological disinfection, and UF for fine particle and microbial filtration — covering the three essential purification technologies in a single compact unit.
  • Antioxidant alkaline filter (select models): Select Dolphin models include an antioxidant alkaline cartridge that raises output water pH and adds mineral content post-RO — improving taste and adding the antioxidant properties associated with alkaline drinking water.
  • Automatic shut-off when tank is full: All Dolphin RO models include an automatic motor shut-off when the storage tank reaches capacity — protecting the pump motor from dry-run damage and extending overall purifier lifespan.
  • Food-grade ABS plastic housing: Dolphin purifier bodies use food-grade ABS plastic — a non-toxic, durable material that does not leach chemicals into stored purified water under normal operating temperatures.
  • 80 GPD RO membrane: The 80 Gallon Per Day (80 GPD) RO membrane in Dolphin purifiers handles moderate TDS levels effectively — delivering 10 to 15 LPH of purified water output sufficient for daily household drinking and cooking needs.

Why choose a Dolphin water purifier

Dolphin water purifiers suit budget-conscious buyers who need reliable multi-stage RO purification without the premium pricing of established national brands. Here is why they stand out in their segment.

  • Accessible pricing for multi-stage RO purification: Dolphin purifiers deliver RO+UV+UF three-stage purification from Rs. 5,500 — making comprehensive water purification accessible for households that cannot stretch to Rs. 8,000 to Rs. 12,000 mid-tier models from national brands.
  • Compact wall-mounted design for small kitchens: Dolphin units occupy minimal wall space — their compact 33 × 30 × 46 cm footprint suits small Indian kitchens, rental apartments, and office pantry areas where counter and cabinet space is limited.
  • Alkaline and mineral booster options in the range: Select Dolphin models add antioxidant alkaline filtration and mineral booster cartridges post-RO — features typically found only in premium mid-range models from national brands, delivered at Dolphin's accessible price points.
  • Available through local dealers for accessible service: Dolphin purifiers sell through regional water treatment dealers across South India, Maharashtra, and Gujarat — making installation, filter replacement, and basic service accessible through local technicians without national brand AMC dependency.
  • Suitable for moderate TDS municipal and borewell water: Dolphin's 80 GPD RO membrane handles moderate TDS input effectively — suitable for the majority of Indian municipal and mixed-source households with TDS between 300 and 800 ppm.

Maintenance tips for Dolphin water purifiers

Regular maintenance keeps your Dolphin water purifier performing safely and extends its service life beyond the standard warranty period. Here are the key maintenance steps.

  • Replace the sediment pre-filter every 3 to 6 months: The sediment filter traps coarse particles before the RO membrane — in hard or high turbidity water, replace it every 3 months to prevent pressure drop across the RO membrane and maintain purification flow rate.
  • Replace the activated carbon filter every 6 months: The carbon filter removes chlorine, organic compounds, and odours before the RO membrane — replace every 6 months regardless of visible colour change, as chemical adsorption capacity depletes before any visual indication.
  • Replace the RO membrane every 12 to 18 months: The 80 GPD RO membrane in Dolphin purifiers requires replacement every 12 to 18 months depending on input TDS and daily usage — a deteriorating membrane reduces TDS rejection without any visible performance change.
  • Replace the UV lamp annually: UV lamps lose approximately 40% of their germicidal output after 8,000 to 9,000 hours of operation — replace annually regardless of whether the lamp appears to be functioning, as UV intensity loss is not visible to the naked eye.
  • Clean the storage tank every 6 months: Drain the tank completely, wipe the interior with a clean cloth dampened with diluted food-grade hydrogen peroxide, rinse thoroughly with purified water, and refill — preventing biofilm accumulation on the inner tank surface between service visits.

Which technology is used in Dolphin water purifiers?

Dolphin water purifiers use RO (Reverse Osmosis), UV (Ultraviolet), and UF (Ultrafiltration) purification technologies in combination. RO removes dissolved salts, heavy metals, and TDS using an 80 GPD membrane. UV kills bacteria, viruses, and cysts through germicidal radiation. UF provides additional fine particle and microbial filtration. Select Dolphin models add an antioxidant alkaline filter or mineral booster cartridge post-RO for improved water taste and mineral content.

Is a Dolphin water purifier safe for drinking water?

Yes — Dolphin water purifiers using RO+UV+UF technology produce safe drinking water when maintained correctly and matched to a water source within the purifier's rated TDS input limit. The RO membrane removes dissolved contaminants and heavy metals; UV kills microbial threats; UF provides additional filtration. Replace filters on schedule — sediment every 3 to 6 months, RO membrane every 12 to 18 months, and UV lamp annually — to maintain consistently safe output water quality.

What is the storage capacity of Dolphin water purifiers?

Dolphin water purifiers are available with storage tank capacities ranging from 7 L to 12 L depending on the specific model. The 7 L model suits small families of 2 to 3 members. The 9 L model suits families of 3 to 4 members for daily drinking and cooking use. The 12 L model suits larger families of 4 to 6 members or households in areas with frequent power cuts where larger stored reserves are necessary.

How much water can a Dolphin water purifier purify per hour?

Dolphin water purifiers deliver a purification flow rate of 10 to 15 litres per hour depending on the model and input water pressure. The 80 GPD RO membrane supports a maximum daily output of 100 to 120 litres per day — sufficient for a family of 3 to 5 members consuming 10 to 15 litres of purified water daily for drinking and cooking. Purification rate reduces at lower input water pressure below the recommended 4 PSI minimum.
