Calculate Whole-House Sizing

Planning Whole-House Filtration for Your Home?

Sizing a whole-house system requires balancing bathroom count, peak family occupancy, and raw water source chemistry. Take our free 2-minute assessment for an engineered sizing recommendation.

Anatomy of a Premium Whole House Filtration System

A complete whole-house filtration installation incorporates a strategic multi-barrier design tailored to the property’s water source:

Stage 1: High-Flow Dual-Gradient Sediment Filter (20-Inch Big Blue): Traps coarse sand, pipe scale, algae, and suspended rust down to 5 microns, protecting internal valves and ceramic shower cartridges from abrasive wear.
Stage 2: Automatic Multi-Media Filtration Vessel (Sand & Anthracite): For deep borewell water with high turbidity, a heavy-duty fiberglass vessel packed with graded quartz silica and anthracite coal polishes water to crystal clarity.
Stage 3: Catalytic Carbon Absorption Column: High-iodine-value coconut shell carbon chemically adsorbs free chlorine, trihalomethanes (THMs), and offensive sulfur odors, ensuring shower steam is completely free of chemical vapor.
Stage 4: Automated Ion-Exchange Softener (Optional for Hard Water): For hard groundwater, a digital water softener exchanges calcium and magnesium ions for sodium, eliminating limescale stains on Italian marble, bathroom glass, and clothing.
Stage 5: Kitchen Point-of-Use Drinking RO: While the whole house enjoys clean, sediment-free, soft water for bathing and cleaning, a specialized under-sink or wall-mounted RO in the kitchen provides surgical-grade mineral-balanced drinking water.

Villa Whole House Benefits vs Kitchen RO Alone

Impact Dimension	Kitchen RO Alone	Complete Whole House POE System
Drinking & Cooking Water	100% Pure	100% Pure (via dedicated kitchen RO)
Showering & Hair Health	Unfiltered raw water (hair fall & dry skin)	Chlorine-free, soft, skin-nourishing water
Plumbing Fixtures & Tiles	Stained with white limescale & rust	100% stain-free, pristine chrome & glass
Appliance Longevity	Geysers & washing machines scale up	Heating elements & appliances last 2–3x longer
Water Flow Delivery	15–20 LPH (Kitchen tap only)	2,500 – 4,000 LPH across all bathrooms simultaneously

5-Year Financial & Asset Protection Analysis

While a whole-house system represents a significant upfront installation, it safeguards millions of rupees worth of luxury interior infrastructure:

Expense / Asset Protected	Year 1	Year 2	Year 3	Year 4	Year 5
Initial System & Installation	₹65,000	₹0	₹0	₹0	₹0
Big Blue Sediment Replacement	Covered	₹2,400	₹2,400	₹2,400	₹2,400
Carbon Bed Reconditioning	Covered	₹0	₹4,500	₹0	₹4,500
Plumbing Valve / Tile Repairs	₹0 (Protected)	₹0 (Protected)	₹0 (Protected)	₹0 (Protected)	₹0 (Protected)
Annual Service & Inspection	₹0	₹1,200	₹1,200	₹1,200	₹1,200
Annual Total	₹65,000	₹3,600	₹8,100	₹3,600	₹8,100

The 5-year running cost totals ₹88,400—a modest fraction of the cost to replace stained Italian marble, corroded Grohe/Kohler bathroom fixtures, or burned out washing machine solenoids.

Frequently Asked Questions

Where is a whole house filtration system physically installed?

In independent villas and bungalows, the system is typically installed either near the ground-level transfer pump (between the underground sump and overhead tank) or immediately after the overhead rooftop tank on the gravity/pressure-booster delivery header. In apartments, it can be installed on the main inlet shaft line entering the flat.

Does a whole house filter reduce water pressure in my bathrooms?

Properly sized whole-house systems utilize oversized 1-inch or 1.25-inch high-flow ports and high-surface-area media beds that produce negligible pressure drop (less than 0.2 bar). If your home already has low gravity pressure, our engineers recommend pairing the filter with an automated variable-speed booster pump.

Can I drink water directly from bathroom sink taps with a whole-house filter?

Whole house systems make bathroom water pristine, sediment-free, and chlorine-free—making it completely safe for brushing teeth and accidental swallowing while showering. However, for daily drinking and cooking, we still recommend drawing from your dedicated kitchen RO purifier, which eliminates micro-solute heavy metals and dissolved fluorides.

How does the automatic backwash valve work?

The automatic multi-port valve features a digital programmable timer. Typically set to activate at 2:00 AM once a week, the valve automatically reverses water flow upwards through the media bed for 10 minutes, lifting and flushing accumulated dirt and silt out through a drain pipe. Once complete, it automatically returns to service mode.

Buying Guide: How to Choose the Right Water Purifier

Choosing the best water purifier depends heavily on the quality of your source water. Here are the most critical factors to consider:

1. Test Your Water Source (TDS Level)

Total Dissolved Solids (TDS) determines which purification technology you need:

Low TDS (below 200 ppm): Typically found in municipal water. A UV + UF purifier is sufficient to kill bacteria and remove cysts without stripping essential minerals.
High TDS (above 200 ppm): Found in borewell, tanker, or mixed sources. You absolutely need an RO (Reverse Osmosis) purifier to remove heavy metals and excess salts.

2. Multi-Stage Purification (RO+UV+UF+MTDS)

Modern purifiers combine multiple technologies. RO removes dissolved impurities, UV kills microorganisms, and UF removes suspended particles. If you use RO, ensure it has a TDS Controller (MTDS) or Mineralizer to add essential minerals back into the water.
