The Ultimate 2026 Alkaline RO Buying Guide
Choosing the right alkaline RO water purifier for your home in India can be confusing with hundreds of models in the market. This complete guide will help you choose the perfect Alkin Water purifier based on your water quality, family size and budget.
Step 1: Test Your Water TDS First
Get your water tested for TDS (Total Dissolved Solids):
- Below 200 ppm: UV + UF + Alkaline filter is sufficient
- 200-1000 ppm: RO + Alkaline + UV is recommended
- Above 1000 ppm: Heavy-duty 10-stage Alkin RO + Alkaline mandatory

Step 2: Look for These 10 Stages
- Sediment filter - removes dust and rust
- Pre-carbon filter - removes chlorine and odors
- Pre-RO filter - protects RO membrane
- RO membrane - removes 99.9% TDS, heavy metals
- Post-carbon filter - improves taste
- UV chamber - kills bacteria and viruses
- UF membrane - additional bacterial protection
- Alkaline cartridge - boosts pH to 8.0-9.5
- Mineral cartridge - adds Ca, Mg, K back
- Copper cartridge (optional) - copper-infused water benefits
Step 3: Check Storage Capacity
For a family of 4-6, choose 8-12 litre storage tank. Larger families or offices need 15+ litre or commercial RO plants.
Step 4: Verify Certifications
Look for ISI, BIS, NSF, WQA certifications. Alkin Water carries all major Indian certifications.
Step 5: Consider After-Sales Service
RO purifiers need yearly filter changes. Choose a brand with strong service network. Alkin Water has 24/7 toll-free support and certified technicians in 26,000+ pincodes.
