Find the Right RO Water Purifier for Your Home in Just 6 Easy Steps

Choosing the right water purifier can be confusing. Water quality, TDS level, family size, purification technology, and budget all play an important role.

Our Aquafresh Water Purifier Buying Guide helps you choose the perfect water purifier based on your specific needs.

Step 1: Know Your Water Source

The first step is to identify where your drinking water comes from.

Water Source Recommended Purifier
Municipal Tap Water UV + UF
Borewell Water RO + UV + UF + TDS Controller
Tanker Water RO + UV + UF + TDS Controller
Mixed Water Supply RO + UV + UF + TDS Controller

Tip: If your water source changes frequently (municipal + tanker), always choose an RO purifier.

Step 2: Check Your Water TDS Level

TDS (Total Dissolved Solids) is the most important factor while buying a water purifier.

TDS Level Water Quality Recommended Technology
Below 100 ppm Low TDS UV + UF
100–300 ppm Normal UV + UF or RO (Optional)
300–500 ppm Medium RO + UV + UF
500–1000 ppm High RO + UV + UF + TDS Controller
Above 1000 ppm Very High High Recovery RO System

Don't know your TDS?

Use an inexpensive TDS meter or request a water quality test before purchasing.

🔍 TDS-Based Product Selector

Use your TDS reading below to find the right Aquafresh purifier category. Always test your local water before purchase — actual water quality may vary by season and supply source.

Your TDS Reading Water Quality Recommended Technology Booster Pump Needed? Shop Collection
Below 100 ppm Low — Soft Water UV + UF (No RO needed) ❌ Not required Gravity / UF Purifiers · UV Purifiers
100–300 ppm Normal — Acceptable UV + UF or Light RO ❌ Usually not required Low TDS Purifiers (<300 ppm)
300–500 ppm Medium — Needs RO RO + UV + UF ⚠️ Check inlet pressure (min 5 psi required) RO Purifiers · Best Sellers
500–1000 ppm High — Standard RO RO + UV + UF + TDS Controller ⚠️ Recommended if inlet pressure is low RO Purifiers · Best Sellers
Above 1000 ppm Very High — Hard Water High Recovery RO (up to 4000 ppm rated) ✅ Required — booster pump essential High TDS RO (up to 4000 ppm)

⚠️ Caution: TDS levels can vary by season, locality, and supply source. Always test your water with a calibrated TDS meter before purchasing. Purifier performance depends on actual inlet water quality, pressure, and usage. Contact Aquafresh Customer Care for a free recommendation based on your specific conditions.

💧 Do You Need a Booster Pump?

  • If your home has good water pressure (municipal supply, upper floors with overhead tank) — a booster pump is generally not required for TDS below 1000 ppm.
  • If your water pressure is low (ground-floor borewell, tanker supply, older buildings) — a booster pump ensures proper RO membrane function and better water output.
  • For TDS above 1000 ppm — a booster pump is essential for effective RO purification.
  • Check your inlet pressure before installation. RO purifiers typically require a minimum of 5–40 psi (0.35–2.8 bar) to operate correctly.

✅ Pre-Installation Checklist

  • Measure your water TDS with a digital TDS meter
  • Identify your water source (municipal / borewell / tanker)
  • Check available wall space or counter space for mounting
  • Confirm inlet water pressure is adequate
  • Ensure a power outlet (for electric models) is within reach
  • Verify drain pipe access for RO waste water

Frequently Asked Questions

Do I need an RO purifier if my TDS is below 300 ppm?

Generally, UV + UF purification is sufficient for low-TDS municipal water. RO is recommended when TDS is above 300 ppm or if your water contains high levels of dissolved salts.

Which water purifier is best for borewell water?

An RO + UV + UF purifier with a TDS controller is recommended because borewell water often has higher TDS and hardness.

Which storage capacity is best for a family of four?

An 8–10 litre storage tank is suitable for most families of four.

Is Copper RO better than a standard RO purifier?

Copper RO models add copper-infused water after purification. If you prefer this feature, choose a Copper RO model, while ensuring the purifier also meets your water quality requirements.

How can I measure my home's TDS?

You can use a digital TDS meter or contact Aquafresh Customer Care for guidance on checking your water quality before purchasing.
