MainLine Filter 20 Inch (1 Stage) – Ideal for 2 Bath + Kitchen | Hard Water & Sediment Filter
Protect your entire home from hard water and sediment with the MainLine Filter (20 Inch, 1 Stage).
Perfect for 2 bathrooms + a kitchen, it ensures cleaner, clearer water for every tap, shower, and appliance — without electricity or salt.
The MainLine Filter 20 Inch (1 Stage) is a whole-house filtration system tailored for Indian homes with 2BHK or 3BHK setups.
Installed at the main water supply, it effectively removes sand, dust, rust, and other suspended solids while also conditioning hard water to prevent white scaling on tiles, taps, and fittings.
Its 20-inch jumbo housing allows high flow (1200–1500 litres/day), maintaining steady water pressure.
The dual-function filter combines sediment removal and anti-scale conditioning — ideal for borewell, tanker, or municipal water.
Crafted from food-grade polypropylene, it’s built to perform under variable pressures and is backed by a 2-year housing warranty.
