Stand Out Features: 

• 10-Stage Filtration: It has an extensive number of stages before the water gets dispensed into your glass to ensure that you are always protected from germs and chemicals.

What’s Not Great: 

Requires professional installation

Comparative Analysis: The M2 by Urban company offers a high level of filtration with 10 stages, which is more than other branded models on this list. After that, it allows users to be stress-free with fewer service requirements, saving you up to Rs. 13,500 over 6 years.

Kent Supreme Alkaline is a well-rounded water purifier that provides safe and clean drinking water by combining RO, UV, and UF filtration. Its alkaline ability raises the pH of the liquid, thereby improving hydration and possibly improving digestion and general health. Its eco-friendly zero-wastage technology, which ensures that rejected water is recycled back into the overhead tank (where it came from) is attractive to many. A post-carbon filter ensures a refreshing experience by enhancing the water's flavor and odor.

This ensures that all chemicals are removed with a pre-carbon filter, and the post filter improves the taste and odor. 

Stand Out Features: 

• UV UF Water Filter: It employs ultraviolet light in the tank to take care of present and growing germs, and the UF (Ultra Filtration) removes all kinds of larger particles.

Kent is known to be more affordable than others in its class, but it does offer slightly fewer perks. When compared to Native M2, it has less filtration but has the Alkaline benefit, similar to AO Smith Z5 Pro. This also requires the filters to be maintained every 12 months, which can increase the lifetime cost even though it has less initial cost for those looking for options in the best water purifier under 15000 category. Though it comes with an AMC plan, filter changes and spare part changes usually cost extra, leading to a 5000-6000 Rs cost year on year, including the AMC plan.

However, once the 24-month long warranty period is over, it requires a filter change every 12 months, similar to other models.
• 7-Stage Purification: Equipped with RO, UV, and UF filters, along with other ones, this model removes contaminants like heavy metals, bacteria, and viruses while keeping essential minerals in the water. 
• Drinking Advice: Through the app, it allows users to see how much water they should be drinking as per the AQI, temperature, and humidity at the moment, keeping your body properly hydrated. 

What’s Not Great:

• Higher Initial Cost and Year-on-Year maintenance needs once the warranty period of 2 years are over. 

Comparative Analysis:

The Aquaguard Ritz Pro is one of the most feature-packed water purifiers with smart connectivity, making it stand out against Kent RO Alkaline, which lacks app-based monitoring. However, Native M2 has more filtration stages and has lesser maintenance costs compared to Aquaguard Ritz Pro. While Aquaguard may cost around 4000-5000 every year on AMC and service costs, Native M2 only costs 4500, and that too once in 2 years.

Able to retain the taste and minerals, this AO Smith water purifier comes with a mineralizer and alkaline benefits. It maintains the pH balance, which regulates the taste from the copper tank and ensures that your body stays less acidic and more hydrated. If you live in a smaller living space or don’t live with many people, its smaller tank capacity of 5 litre would ensure less wastage of excess water purification. Through the silver-charged membrane technology, the level of filtration is improved by a ton, and there are fewer chances of bacteria growth.

• MIN-TECH Mineraliser: What makes it one of the best RO water purifiers is its effective re-adding of essential minerals like calcium and magnesium to the water. This acts similarly to the 4-in-1 health boost of Native M2 and infuses water with essential minerals.
• Ideal for Compact Spaces: With a 5-liter water tank, this water tank would be able to provide small families with their daily clean water needs while also being less expensive than other models. Bigger families can struggle with using this capacity. 

What’s Not Great:

• Smaller Tank with no UV LED 

Comparative Analysis:

The AO Smith Z5 Pro is perfect for those who prioritize alkaline water benefits over smart features and comes with mineral retention features as well. However, in comparison to Native M2, it has fewer stages of filtration and comes with a 5L tank, which might not be sufficient for families.

Combining purification with traditional health benefits, the HUL Pureit Copper+ Eco takes the untreated water through copper, known for its antimicrobial and immunity-boosting properties. Its DURAViva technology makes the filter life longer and minimizes the need for frequent replacements. The eco-recovery system ensures minimal water wastage, making it a sustainable choice. Though the copper chamber requires occasional cleaning, its combination of purification, mineral retention, and sustainability makes it a strong competitor in the market.

• Eco Recovery System: Many ROs can waste a lot of water, but not this one. This Pureit water purifier ensures that up to 80% of water is recovered, making it one of the best water filters in India. 

What’s Not Great:

• Copper Chamber Needs Regular Cleaning Leading To Higher Technician Costs in the Long Run 

Comparative Analysis:

The HUL Revito Prime is a great option for those who want a water purifier with a copper tank and minimal wastage. It comes with a water-saving benefit, but when we consider maintenance, it is heavy on maintenance with 4000-5000 yearly costs on filter change, which leads to a higher lifetime ownership cost.
