Frequently Asked Questions

Which is the No. 1 water purifier?
While the 'No. 1' purifier depends on your specific water source, premium models like the AO Smith Z9 Pro and Aquaguard ASPIRE Blaze are frequently ranked at the top due to their advanced multi-stage RO+UV+UF purification and smart features.
Which brand is best for purifying water?
In the premium segment, Kent, Aquaguard (Eureka Forbes), AO Smith, and LG are widely considered the best brands. They offer superior build quality, nationwide service networks, and advanced technologies like Copper and Alkaline enrichment.
Which RO is best in 2026?
The best ROs in 2026 feature 100% RO+UV purification, Zero Water Wastage technology, and smart IoT connectivity. Flagship models from top brands consistently dominate this space.
Which is India's no. 1 water brand?
Aquaguard by Eureka Forbes is historically considered India's No. 1 water purifier brand in terms of legacy and trust, though Kent has closely rivaled it in recent years as a market leader in RO technology.
Is Kent better or Aquaguard?
Both are excellent, but they excel differently. Kent is highly renowned for its robust RO technology and high-recovery rates, while Aquaguard is praised for its customized cartridges (like Active Copper) and sleek, modern aesthetics.
Which is better, RO or UV?
RO (Reverse Osmosis) is better for hard water (high TDS, borewell), as it removes dissolved salts and heavy metals. UV (Ultraviolet) is better for soft municipal water (low TDS) as it kills bacteria and viruses without wasting water or removing natural minerals.
Is RO water safe for kidneys?
Yes, RO water is completely safe for kidneys. However, basic RO purifiers strip out all minerals. To ensure you are getting healthy water, it's best to choose a premium RO with a Mineralizer or MTDS controller that adds back essential minerals like Calcium and Magnesium.
Which type of purifier is best?
The best type of purifier depends on your water's TDS (Total Dissolved Solids). If TDS is above 300 ppm, a multi-stage RO+UV+UF purifier is best. If TDS is below 300 ppm, a UV+UF purifier is the safest and most efficient choice.
Is UV water safe to drink?
Yes, UV purified water is 100% safe from biological contaminants. The UV light deactivates the DNA of bacteria, viruses, and cysts. However, it does not remove dissolved chemicals or heavy metals, which is why it should only be used on low-TDS municipal water.
Which is the best purifier brand?
For premium features and reliability, AO Smith and LG are top choices. For widespread serviceability and budget-to-premium range, Kent and Aquaguard are the best options.
Which is the most expensive water purifier?
The most expensive domestic water purifiers are flagship models from brands like LG, AO Smith, and Havells, often costing between ₹25,000 and ₹35,000. These models feature stainless steel tanks, touch displays, hot/cold dispensing, and smart app integration.
Which Aquaguard water purifier is the best?
The Aquaguard ASPIRE Blaze and the Aquaguard Aura (with Active Copper and Zinc) are currently among the highest-rated premium models, offering excellent purification, mineral enrichment, and aesthetic design.
