1. Pureit Eco Water Saver RO+UV+MF
The Pureit Eco Water Saver is the best-priced full RO+UV+MF purifier on this list at Rs. 11,999 and carries a standout feature that justifies the name: up to 60% water savings compared to traditional RO designs. Standard RO purifiers reject 2 to 3 litres of water for every litre purified. The Pureit Eco Water Saver dramatically reduces that wastage, which is a practical advantage for homes in water-scarce cities or those on a metered water supply. The 10L storage tank is larger than most in this segment. With over 2,700 ratings and 400+ purchases per month, the Pureit Eco Water Saver is one of the most actively bought purifiers in this range. HUL’s Pureit brand carries a strong service infrastructure across India.
2. KENT Grand RO Water Purifier
The KENT Grand is KENT’s most popular RO model and one of the best-selling water purifiers in India, with over 7,300 ratings and 1,000+ purchases per month. The RO+UF+TDS Control combination removes dissolved solids through the RO membrane, blocks bacteria and cysts through UF, and uses the TDS controller to retain essential minerals while removing harmful salts. The UV LED tank keeps stored water continuously sterilised even during storage, which is a feature most competitors in this price range do not offer. At 20 litres per hour, the KENT Grand has enough throughput for a large family. KENT’s service network is the largest for water purifiers in India, available across major cities, towns, and even tier-3 locations. At Rs. 12,899, the KENT Grand is the safest, most established choice at this price point.
3. Livpure Allura Prime RO+UV+UF+Copper+Alkaline
Livpure Allura Prime Water Purifier (RO+UV+UF+Copper+Alkaline, 7L)
The Livpure Allura Prime packs the most purification stages on this list at Rs. 12,999, combining RO, UV, UF, copper enrichment, and alkaline filtration in a 10-stage process. The copper enrichment feature adds copper ions to the purified water, which has traditional Ayurvedic backing and is associated with antibacterial properties. Alkaline filtration raises the water pH above 7, which some buyers prefer for health reasons. The most compelling feature of the Livpure Allura Prime is its zero filter replacement cost for 2 years, which means the filters are included in the purchase price, and Livpure handles replacements at no additional charge for 24 months. In-tank UV sterilisation keeps stored water safe continuously. With 400+ monthly purchases, the Livpure Allura Prime is the best-value premium purifier at this price.
4. KENT Supreme Plus Alkaline+Copper RO Water Purifier
The KENT Supreme Plus is the most reviewed water purifier on this list, with over 18,800 ratings, which is an extraordinary level of buyer feedback for a home appliance. The KENT Supreme Plus adds alkaline and copper enrichment on top of KENT’s standard RO+UV+UF combination, along with TDS Control and UV LED tank sterilisation. The Auto Flush feature automatically flushes the RO membrane at set intervals to keep it clean and extend its lifespan, reducing long-term maintenance costs. At Rs. 15,599, the KENT Supreme Plus is the go-to choice for buyers who want KENT’s trusted service network combined with the most comprehensive feature set in the mid-range bracket. The 18,800+ review count gives you far more social proof than any other option at this price.
5. Native M1 Water Purifier by Urban Company
The Native M1 by Urban Company is the most disruptive product on this list. Urban Company, India’s largest home services platform, designed the Native M1 around one promise: no service required for 2 years. The high-capacity filters are engineered to last 24 months without replacement, eliminating the annual filter change cost that most purifier brands charge Rs. 1,500 to Rs. 3,000. The 2-year unconditional warranty, which is the first of its kind in India according to the brand, covers all defects and failures. The 10-stage purification includes RO, UV, copper enrichment, alkaline filtration, and mineralisation. With over 6,500 ratings and 2,000+ monthly purchases, the Native M1 has proven itself as a genuine alternative to established purifier brands. If a low total cost of ownership over 2 years matters to you, the Native M1 is the most compelling argument on this list.
6. KENT Grand Plus RO Water Purifier
KENT Grand Plus RO Water Purifier (9L, 20 LPH, ISI Marked)
The KENT Grand Plus is KENT’s flagship model on this list and the most fully loaded option under Rs. 20,000. The 4 years of free service included with the KENT Grand Plus is a premium offering that dramatically reduces the real cost of ownership over four years. ISI marking (IS 10500) means the KENT Grand Plus meets India’s drinking water standards as a purified output, which is a government-backed quality certification. The 9L tank is the largest storage capacity on this list, suitable for large families or homes with an inconsistent power supply. The Zero Water Wastage technology recovers rejected RO water for household use, like cleaning or washing. At Rs. 19,998, the KENT Grand Plus is for buyers who want the most comprehensive package from India’s most trusted water purifier brand with a four-year service commitment.
How to Choose an RO Water Purifier Under Rs. 20,000
Is RO Necessary for Your Water?
RO is essential if your water TDS exceeds 300 ppm or if you are on a borewell or tanker supply. If you are on municipal water with TDS below 200 ppm, a UV+UF purifier at a lower cost handles biological contamination adequately. A simple TDS meter (available for under Rs. 200 on Amazon) helps you check your water before buying.
Service and Filter Replacement Cost
This is the highest hidden cost of water purifier ownership. Most standard RO purifiers charge Rs. 1,500 to Rs. 3,000 annually for filter replacements. The Native M1 and Livpure Allura Prime eliminate this cost for 2 years. The KENT Grand Plus includes 4 years of free service. Factor in the total 3-year ownership cost when comparing models on sticker price alone.
Alkaline and Copper Features
Alkaline water (pH above 7) and copper-enriched water are increasingly popular in Indian households for perceived health benefits. The KENT Supreme Plus, Livpure Allura Prime, and Native M1 all include one or both of these features. If these are priorities, they narrow your choice quickly.
Storage Tank Size
8 to 10L is adequate for most families of four. The KENT Grand Plus offers 9L, which is the largest on this list. The Pureit Eco Water Saver has a 10L tank, the most generous in its price range.
Brand Service Network
KENT and Pureit (HUL) have the widest service networks in India, covering tier-2 and tier-3 cities. Livpure and Native M1 by Urban Company are strong in metros. If you are outside a major city, KENT or Pureit is the safer choice for quick servicing.
Frequently Asked Questions
Which is the best RO water purifier under Rs. 20,000 in India?
The KENT Grand (Rs. 12,899) is the best all-round pick for buyers who prioritise brand trust and service network. The Native M1 (Rs. 15,999) is the best choice for buyers who want zero service cost for 2 years. The KENT Grand Plus (Rs. 19,998) is the best comprehensive pick with 4 years of free service and ISI marking.
What is the difference between KENT Grand and KENT Grand Plus?
The KENT Grand (Rs. 12,899) comes with an 8L tank and does not include free service. The KENT Grand Plus (Rs. 19,998) upgrades to a 9L tank, adds 4 years of free service, ISI marking, and Zero Water Wastage technology. The Rs. 7,099 price gap is essentially the value of 4 years of service bundled in.
Is the Native M1 really no service for 2 years?
Yes, according to Urban Company’s product specification. The Native M1 uses high-capacity filters designed to last 2 years without replacement under normal household usage conditions. The 2-year unconditional warranty covers any failures during this period. Buyers with very high water consumption or exceptionally hard water may see shorter filter life than the stated period.
Is the Livpure Allura Prime worth buying over the KENT Grand?
The Livpure Allura Prime (Rs. 12,999) is just Rs. 100 more than the KENT Grand (Rs. 12,899) but adds copper enrichment, alkaline filtration, UF, and zero filter cost for 2 years that KENT Grand does not have. On features, the Livpure Allura Prime wins at the same price. On service network reach and brand trust, KENT wins. The choice depends on whether you are in a city with good Livpure service coverage.
What is TDS Control in KENT water purifiers?
TDS Control is KENT’s proprietary technology that blends a small portion of unfiltered water with the RO-purified water before dispensing. This retains essential minerals like calcium and magnesium that the RO membrane removes, giving you water that is safe but not completely demineralised. The KENT Grand, KENT Supreme Plus, and KENT Grand Plus all include TDS Control.
Does a RO water purifier reduce water pressure?
RO purifiers typically require a minimum inlet pressure of 5-10 psi to operate the membrane. If your home water pressure is low (common in upper floors or older buildings), you may need a booster pump attachment. Most service technicians check and address this during installation. If pressure is a known issue in your building, confirm with the brand’s installation team before buying.
