1. Technology: Mineral RO™ vs Active Copper Maxx™
Kent pioneered the concept of “Mineral RO” in India. Standard RO systems strip away essential minerals (like calcium and magnesium) along with harmful toxins. Kent’s patented TDS controller bypasses a portion of the water through a UF membrane to retain essential natural minerals, ensuring your water remains healthy and alkaline.
Aquaguard (Eureka Forbes) counters this with their Active Copper Maxx and MTDS (Taste Adjuster) technologies. Instead of just retaining natural minerals, their cartridges infuse Copper, Zinc, and Calcium ions back into the purified water. Copper is highly regarded in Ayurveda for boosting immunity and aiding digestion.
2. Build Quality & Design
Kent purifiers are instantly recognizable for their transparent, wall-mounted designs. This was a genius move—allowing consumers to visually see the water inside the tank builds immense trust. Their food-grade ABS plastic is highly durable and prevents toxic leaching.
Aquaguard tends to focus on sleeker, more modern aesthetics. Models like the Aquaguard Aura or Marvel blend seamlessly into high-end modular kitchens, looking more like premium home appliances than industrial filters.
3. After-Sales Service & Maintenance (AMC)
This is where Aquaguard holds a historical advantage. Being the oldest player in the market, Eureka Forbes has a deep penetration of service technicians across Tier 1, Tier 2, and Tier 3 cities in India.
However, Kent has aggressively expanded its service network over the last 5 years. While their replacement filters can sometimes be slightly more expensive, the robust build quality of their RO membranes often means they last longer before requiring replacement.
Frequently Asked Questions
Which is better: Kent or Aquaguard?
Both are exceptional brands. Kent is generally better for hard, high-TDS borewell water due to its robust RO membranes and zero-water wastage tech. Aquaguard is excellent for municipal water and users looking for active copper and zinc enrichment.
Are Aquaguard service costs higher than Kent?
Historically, the Annual Maintenance Contract (AMC) for both brands is quite similar, ranging from ₹4,000 to ₹5,500 depending on the model and the frequency of filter changes required by your local water quality.
Buying Guide: How to Choose the Right Water Purifier
Choosing the best water purifier depends heavily on the quality of your source water. Here are the most critical factors to consider:
1. Test Your Water Source (TDS Level)
Total Dissolved Solids (TDS) determines which purification technology you need:
- Low TDS (below 200 ppm): Typically found in municipal water. A UV + UF purifier is sufficient to kill bacteria and remove cysts without stripping essential minerals.
- High TDS (above 200 ppm): Found in borewell, tanker, or mixed sources. You absolutely need an RO (Reverse Osmosis) purifier to remove heavy metals and excess salts.
2. Multi-Stage Purification (RO+UV+UF+MTDS)
Modern purifiers combine multiple technologies. RO removes dissolved impurities, UV kills microorganisms, and UF removes suspended particles. If you use RO, ensure it has a TDS Controller (MTDS) or Mineralizer to add essential minerals back into the water.
3. Maintenance and After-Sales Service
A water purifier is a long-term commitment. Filters typically need replacing every 6 to 12 months. Always check the Annual Maintenance Contract (AMC) cost before buying. Brands like AO Smith, Aquaguard, and Kent have strong pan-India service networks.
