Water is necessary for leading a healthy life, and in a city like Coimbatore itself famous for hot weather, increasing urbanization, and unpredictable water quality, the right water purifier is the need. With increasing issues with water impurity, hard water, and high Total Dissolved Solids (TDS), an RO (Reverse Osmosis) water purifier has become inevitable for domestic and industrial usage.
Understanding Coimbatore’s Water Quality
Even before you invest in a water filter, you need to be sure of the cleanliness of water provided in your area. Water supply source in Coimbatore is special:
• Municipal water supply from Siruvani and Pilloor dams (soft water in contrast to others)
• Borewell or Groundwater in residential societies (hard water with very high TDS)
• Tankers in certain industrial and per-urban areas (could have impurities and bacteria)
While municipal water can have chlorine and trace contaminants, borewell water has to have heavy metals, excess calcium, magnesium, and microbial load.
Why RO Water Purifiers Are Suggested in Coimbatore
RO water purifiers employ a semi-permeable membrane to eliminate:
• TDS (Total Dissolved Solids)
• Heavy metals (lead, arsenic)
• Microbial contaminants (bacteria, viruses)
Excess salts and minerals
Due to the rise in TDS level and occasional water quality skewness in Coimbatore, predominantly during summer or arid seasons, RO filtration typically remains the best option.
Things to Keep in Mind While Selecting an RO Water Purifier in Coimbatore
1. Measure the TDS Level of Your Water
Begin by measuring the TDS of your source water. Try using a TDS meter available for less than ₹500 online.
• Less than 300 ppm: Potable; RO not absolutely needed. Apply UV or UF filter.
• 300 to 600 ppm: No RO required, particularly if there is excess salt and metal in the water.
• More than 600 ppm: RO purifier strongly advised.
In some of the Coimbatore localities that are dependent on borewell water, TDS is above 500–700 ppm, where there is no escaping from RO filtration.
2. Climatic Factors – Why It Is Necessary
Coimbatore’s humid and hot climate encourages bacteria to develop in water storage units. The following can help with climatic-related problems:
• UV Purification: Destroys bacteria and viruses; essential in warmer climates.
• Storage Tank Tight Seal: Prevents microbial contamination.
• Antibacterial Coating: Sustains tank storage cleanliness.
• Mineral Boosting Technology or Copper: Replenishes minerals lost during RO.
3. Select the Best Purification Technology Mix
There is multi-stage purification in new RO water purifiers:
• RO + UV + UF: Suitable for Coimbatore’s two source water
• RO + UV + TDS Controller/Mineralizer: Maintains mineral balance
• RO + UV + MTDS Regulator: Allows you to control taste as per input water
Choose a system with a minimum of 6 to 8 stages of purification if your area’s water quality is poor or the percentage of TDS is high.
4. Storage Capacity
With periodic electricity cuts in some parts of Coimbatore and water scarcity in summer seasons, choose a purifier with sufficient storage capacity (7–10 liters minimum if:
You have 3 to 6 family members
Frequent water or electricity cuts are faced by you
Some models come equipped with automatic refill facilities and low-water reminder for added convenience.
5. Energy Efficiency and Maintenance
In a place like Coimbatore with high average temperature and power consumption a priority, it makes sense to opt for an energy-efficient model.
Opt for smart features such as auto-off, water-saving RO, and filter replacement reminders.
Service networks are also important. Opt for brands that provide effective after-sales services in Coimbatore.
Kent, Livpure, Eureka Forbes (Aquaguard), and Aquascbe have good service networks in the city.
6. Verification of certifications
Your RO purifier should be certified by:
• IS: 16240 (ISI) – Indian Standard for RO systems
• NSF/ANSI certifications – For filter quality
• ISO certification – For product quality and consistency maintenance
This makes the product sound and safe, and you have drinking water that is safe.
7. Budget and Warranty
RO water purifiers in India cost between ₹7,000 to ₹25,000 based on features and model. While selecting one:
• Make sure you are offered a 1-year warranty
• Ask about AMC (Annual Maintenance Contract) charges
• Search for zero-attribution EMI or bundled offers online and offline
Invest in one with low-filter replacement costs which is energy efficient for cost savings in the long term.
