A RO Water Purifier is a water purification system that uses Reverse Osmosis technology to remove dissolved impurities, chemicals, heavy metals, and microorganisms, delivering safe drinking water for home use. It is considered one of the most effective filtration solutions, especially for areas with high TDS levels.
Clean drinking water is a basic need, yet millions rely on water sources filled with harmful contaminants. Rising pollution, industrial waste, and aging pipelines have made it essential for every household to install an efficient water purification system. Among all available options, a RO Water Purifier consistently stands out due to its advanced filtration capability and reliable performance across various water conditions.
Homes today face a wide range of water quality issues such as high TDS, microbial contamination, chlorine, pesticides, and heavy metals. RO technology is specifically designed to handle these challenges and produce clean, odor-free, and great-tasting drinking water. If you are searching for the best water purifier for home, this guide will help you understand how RO works, why it is essential, and how it compares with leading brands such as Aquaguard Water Purifier and Kent Water Purifier.
Reverse Osmosis uses a semi-permeable membrane that filters out contaminants at a molecular level. Water is pushed through the membrane under pressure, leaving impurities behind. The system typically includes multiple stages such as:
Sediment filtration
Activated carbon filtration
RO membrane purification
Post-carbon polishing
Optional UV or UF filters
This multi-step process effectively removes:
Total dissolved solids (TDS)
Heavy metals like lead, arsenic, and mercury
Bacteria and viruses
Pesticides
Chemicals and odors
The outcome is pure, safe, and fresh drinking water suitable for the entire family.

A RO system offers benefits that go beyond simple filtration.
The membrane eliminates microscopic contaminants that ordinary filters cannot remove. This is why RO is recommended for areas with high TDS or industrial pollution.
Unpleasant smells and metallic or salty taste in water are usually due to dissolved solids. RO filtration improves taste significantly.
Long-term exposure to heavy metals and chemicals can lead to serious health conditions. RO removes these threats effectively.
RO purifiers work well with:
Borewell water
Municipal tap water
Tanker water
By ensuring long-term safety and health benefits, RO purifiers help reduce medical costs related to waterborne diseases.
Choosing a water purifier often becomes confusing because of the many technologies available. Here is a clear comparison.
UV technology kills microorganisms but does not remove dissolved solids or chemicals. RO removes both microorganisms and impurities.
UF is useful for low-TDS water but does not remove dissolved salts or hard minerals. RO is necessary for high-TDS areas.
Alkaline systems improve pH and add minerals but do not provide complete purification. RO ensures safety first, and mineral cartridges can restore healthy minerals afterward.
A combined system with RO plus Alkaline is ideal for homes seeking safe water with balanced pH.
Aquaguard is known for innovation and long-lasting build quality. Their RO models often include features such as:
Multi-stage filtration
UV and UF integration
Enhanced mineral technology
Energy-saving modes
Aquaguard is a strong choice for urban households with mixed water supply conditions.
Kent is one of the most trusted names in the Indian water purifier market. Their systems offer:
RO plus UV plus UF purification
High storage capacity
Zero-water waste technology in newer models
Effective TDS control
Kent is highly suitable for borewell and tanker water, especially if TDS levels are above 500 ppm.
Both brands deliver reliable purification. The right choice depends on your water source and family needs.
Finding the best water purifier for home depends on careful evaluation of the following factors:
If TDS exceeds 300 ppm, RO is strongly recommended.
If your source has bacteria or viruses, choose RO + UV.
A larger family benefits from a purifier with a 7 to 12 liter tank.
RO systems require annual servicing. Choose a brand with easy service availability.
RO purifiers come in various price ranges. Compare features instead of selecting solely on price.
Consider enhancements like:
Mineralizer cartridges
Copper storage technology
Alkaline boosters
Digital indicators
These improve water quality and user experience.
Many consumers get confused between RO and alkaline purifiers.
Removes contaminants completely
Reduces TDS significantly
Ideal for hard water
Ensures safety
May reduce natural minerals but restores them through a mineralizer
Increases pH level
Adds minerals
Improves hydration
Does not remove dissolved solids
Not suitable for high-TDS water
The best choice is a combination system: RO + Alkaline Water Purifier. It ensures complete purification while preserving mineral balance.
You can use this checklist before buying a purifier:
RO membrane quality
Pre-filters and carbon filters
UV or UF integration
TDS controller
Mineralizer or alkaline cartridge
Storage tank capacity
Filter life and replacement cost
Auto shut-off
Digital display
Warranty and service network
Choosing a purifier with these features ensures long-term reliability.
Proper installation and regular maintenance ensure peak performance.
Choose a location close to a water inlet and drainage point
Ensure stable water pressure
Keep the unit away from heat sources
Install a pre-filter to improve membrane life
Replace filters on time
Clean the tank regularly
Monitor water taste and flow rate
Schedule servicing every 10 to 12 months
Do not ignore unusual noises or leaks
Timely servicing protects your investment and ensures clean water every day.
RO removes harmful salts. Healthy minerals are reintroduced through a mineral cartridge.
RO water is completely safe. It is the most widely used purification technology worldwide.
RO is ideal for any water source with high contamination, not just hard water.
Newer models include zero-water waste or recycling systems. Waste water can be reused for cleaning or gardening.
Any TDS above 300 ppm usually requires RO purification.
A RO + UV + UF purifier with a mineralizer is ideal for most Indian households.
Sometimes it does, but mineralizers improve taste significantly.
Every 10 to 12 months, depending on usage and water quality.
Alkaline water is beneficial but not a substitute for purification. RO ensures safety, and alkaline systems improve mineral balance.
The best RO water purifier depends on your home’s water quality, TDS level, and family requirements. For areas with high contamination, a RO + UV + UF system is ideal. If you want the perfect combination of purity and mineral balance, choose a RO + Alkaline Water Purifier.
