Best RO Water Purifier for Home (2026): Why Reliant Aqua is the Smart Choice for High TDS Water

Choosing the Best RO water purifier for your home can be overwhelming with so many brands in the market. If you are dealing with hard water, high TDS (Total Dissolved Solids), or groundwater filled with chemical impurities, a standard water filter is not enough.

Reliant Aqua RO Water Purifiers are engineered with advanced multi-stage purification technology (RO+UV+UF+Copper+Alkaline) to safely treat water up to 2000 ppm TDS. It restores essential natural minerals while ensuring 100% bacteria-free, sweet-tasting drinking water for your family.

Why Choose Reliant Aqua Over Traditional RO Purifiers?

1. Advanced 9-Stage Deep Purification

Most conventional purifiers stop at 5 or 6 stages of filtration. Reliant Aqua uses a comprehensive 9-stage sequence to eliminate microscopic threats:

• Pre-Filter & Sediment Filter: Traps mud, sand, dirt, and suspended rust.

• Pre-Carbon Block: Absorbs foul odor, organic volatile compounds, and chlorine.

• High-Clarity RO Membrane: Eradicates heavy metals like arsenic, lead, fluorides, and high salinity.

• UV Disinfection Chamber: Uses high-intensity UV rays to instantly kill viruses, bacteria, and waterborne pathogens.

• Ultra-Filtration (UF): Double-protects the water by filtering out dead micro-organisms.

2. Active Copper & Alkaline Mineral Booster (TDS Controller)

Traditional RO systems strip away healthy minerals along with impurities, making the water acidic and bitter. Reliant Aqua solves this with a Smart Mineral Modulator:

• Alkaline Infuser: Balances the pH level of your water between 7.5 and 8.5, which helps reduce acidity and boosts immunity.

• Active Copper Technology: Infuses trace amounts of copper ions into the water, aiding digestion, skin health, and overall metabolism.

3. High-Recovery Eco Membrane (Low Water Wastage)

Water wastage is a major criticism of ordinary RO systems. Reliant Aqua features a state-of-the-art Eco-Recovery Membrane. It recirculates reject water through a secondary filtration loop, reducing wastewater by up to 50% compared to standard purifiers. This wastewater can easily be saved and reused for cleaning, mopping, or watering household plants.

Step-by-Step Guide: How to Maintain Your RO Water Purifier 

To keep your water purity at 100% and prolong the machine's life, follow this expert maintenance schedule:

1. Sediment Filter Replacement: Clean or replace every 3 to 6 months depending on the input water turbidity (muddy water requires quicker replacement).

2. Carbon Filter Change: Replace every 8 to 12 months to prevent chlorine from damaging the delicate RO membrane.

3. RO Membrane Replacement: A premium Water Purifier membrane comfortably lasts 18 to 24 months under normal residential usage up to 1500 TDS.

4. Sanitization: Sanitize the 8-liter storage tank once every 3 months to prevent biofilm formation.

Frequently Asked Questions - Related to RO Water Purifier

Q1. Is Reliant Aqua suitable for borewell/groundwater supply?

Ans: Yes. Reliant Aqua is explicitly designed to handle heavy groundwater, borewell water, and tanker supply. Its high-capacity RO membrane effectively filters out excessive dissolved salts and hardness up to 2000 ppm, turning brackish water into soft, sweet drinking water.

Q2. What is the ideal safe TDS level for drinking water?

Ans: According to WHO and BIS standards, an ideal TDS level for drinking water is between 50 mg/L and 150 mg/L. Reliant Aqua features an adjustable TDS controller that allows certified technicians to tune the minerals perfectly to your health requirements.

Q3. How does the Alkaline filter in Reliant Aqua help health?

Ans: Regular RO water can sometimes turn slightly acidic (pH below 6.5). Reliant Aqua’s Alkaline filter adds essential minerals like Calcium and Magnesium back into the stream. This raises the pH level, neutralizes excessive body acidity, and enhances hydration.

Q4. Does Reliant Aqua operate without electricity?

Ans: The purification stages (RO and UV pump) require electricity to function. However, the unit comes built-in with an 8-liter hydrostatic storage tank. This ensures you have instant access to pure drinking water even during unexpected power outages.
