Having clean drinking water in every and any home is a must, particularly in the Coimbatore city where the origin of water and nature of water may be completely different in various regions. Whether you are residing in an apartment in Peelamedu, an independent house in Gandhipuram, or a community living house in RS Puram, it is a must that you possess the appropriate water purifier for safeguarding your family members.
Knowing About the Various Water Purifiers
1. RO (Reverse Osmosis) Purifier
Ideal for: Regions with high TDS (Total Dissolved Solids) as well as water hardness.
RO water filters utilize a semi-permeable membrane to remove dissolved salts, heavy metals such as lead, arsenic, and impurities from water. The units also kill microorganisms such as bacteria and viruses when utilized together with UV.
Operating:
• Water flows through several filters.
• The RO membrane removes tiny dissolved salts and impurities.
• Storage tank for purified water.
Main Feature: Lowers TDS and enhances taste and water clarity.
2. UV (Ultraviolet) Water Filter
Best for: Locations with microbiologically polluted but low-TDS water.
UV water purifiers use ultraviolet light to eliminate dangerous bacteria, viruses, and pathogens and make water microbiologically safe.
Operation:
• Water is provided by way of a chamber housing a UV lamp.
• UV rays work on microbial cells and kill their reproductive ability.
• No alteration in the TDS of water.
Key Feature: Eliminates viruses and bacteria, but will not eliminate salts or heavy metals.
3. UF (Ultrafiltration) Purifier
Best applied to: Low TDS areas and high visible particulate mud/dirt in water.
UF purifiers have a membrane that filters out large particles such as sediments, cysts, and certain microorganisms. In contrast to RO, UF does not need electricity and does not remove dissolved salt.
How it works:
• Water passes through a thin mesh membrane known as the semipermeable membrane.
• Catches suspended particulates and a portion of bacteria.
• No electricity or high pressure needed.
• Water Quality in Coimbatore – What You Need to Know
Coimbatore gets its water from:
• Siruvani River (for municipal supply)
• Borewells (largely in peripheral zones)
• Water tankers (in areas of under-supply)
• Aquascbe (water purifier supplier)
Major Sulky Issues in Coimbatore’s Water Supply:
Excess TDS in borewell water: In areas such as Vadavalli, Selvapurm, and Koundampalayam, TDS exceeds 500 ppm.
Bacterial contamination of tanker/stored water: In overhead tank-supplied buildings or private water suppliers, microbial risk dominates.
Hardness and metallic flavor: Prevalent where borewell water isn’t treated.
Therefore, the best purifier varies according to your location, source, and type of impurities.
How to Test Your Water at Home
To select an RO, UV, or UF purifier, you must first know your water’s TDS value and conduct tests for impurities.
Simple ways to test:
TDS meter: For any price at Rs. online or any electronics store. Less than 300 is fine. Above 500 would most likely require RO.
Water test kits: Measures pH, hardness, chlorine, iron, etc.
Lab test: For a more detailed report get your water tested through labs close to Coimbatore.
Selection of the right Purifier Depending on Your Location in Coimbatore
● Borewell-reliant locations (TDS 500+):
Ex: Kalapatti, Saravanampatti, Perur
Select RO or RO+UV purifier
Ensure it has TDS control for beneficial retention of minerals
● Municipal supply locations (TDS < 300):
Ex: Saibaba Colony, Race Course, Gandhipuram
UV or UF purifier will do
UV+UF combination is perfect for added protection
● Utilization of tanker water:
Ex: Neelambur or Avinashi Road outskirts
Select RO+UV for salt and microbial protection
Pre-filter also suggested to remove sediment
Top Most Important Tips While Purchasing a Purifier in Coimbatore
Search for after-sales service centers: Select brands with certified Coimbatore-based service centers for hassle-free filter replacement and maintenance.
Verify water pressure compatibility: RO purifiers require healthy inlet pressure. For low-pressure homes, opt for a model with an integrated booster pump.
Select multi-stage filtration: Especially if your water is mixed-source or unknown quality.
Estimate annual maintenance fees (AMC): RO purifiers are more maintenance-intensive. Ask AMC charges at the time of purchase.
