Buying an RO vs RO on Rent in Delhi: AMC, Filter Changes

Buying a mid-range water purifier costs ₹14,999 to ₹20,999, plus AMC and filter changes. Renting a water purifier spreads the one-time upfront costs. For example, an RO on rent costs ₹14,076 over three years, which is still less than the entry-level price of a mainstream water purifier. So, does renting beat buying? Delhi sees high TDS levels from groundwater and low TDS levels in Delhi Jal Board supply. Since the water TDS levels in Delhi vary by source, it is essential to understand when buying or renting makes sense. 

Why Do Tenants Compare RO on Rent with Buying in Delhi?  

The main reason to compare buying with renting an RO purifier is because of how long a household expects to stay in one place. If you live with your family in your own home, you will plan to keep the RO for years. A tenant who may move for a new job or wants to live closer to the office is less likely to invest in an RO. 

• A professional moving for a new job may notice low or high TDS levels in the drinking water in different areas. 
• Many tenants renew their rental agreement after 11 months because the landlord can hike the rent. So, the chance of staying in the same place is reduced.  

A family that stays in the same house doesn’t see much variation in water quality. Hence, buying an RO makes sense. However, a Dainik Jagran report (January 2026) found that TDS levels in Delhi Jal Board supply in Rohini Sector 20 reached 156 ppm, while groundwater in the same sector reached 556 ppm. A borewell in Maujpur, East Delhi, had TDS levels of 965 ppm. That’s why you can get a home TDS test kit and check the levels to understand whether you need an RO or non-RO purifier.

How Much Does it Cost to Buy and Maintain an RO Purifier in Delhi? 

As per Kent’s online store, mainstream RO purifiers cost between ₹14,999 and ₹20,999 (last checked in September 2026). When the warranty period ends, the AMC is between ₹2,000 and ₹2,500 a year. Kent’s AMC policy states that carbon, UF, carbon, and RO membranes are not covered in the annual maintenance contract. 

Kent charges a separate ₹1,000 service AMC, which covers visit charges and labour; components are not included. The regular AMC for the purifier covers mechanical and electrical parts, but the filters, which are the parts you replace most often, are billed separately.

How Often Does an RO Purifier Need Filter Replacement? 

Most water purifiers for home need their sediment and carbon filters replaced every 6-8 months. The quality of the incoming water may affect the working life of the filters. Also, it depends on usage. For most households, changing one or two filters every year is normal. The RO membrane lasts longer, and it is replaced less often. 

Costs of RO Filter Change

According to Eureka Forbes online, the replacement kit for the Aquagiard Enhance RO ranges between ₹2,701 (Enhance RO kit) and ₹3,048 (Enhance RO EA kit). The EA kit includes a sediment filter, chemi-block, RO membrane, and copper cartridge, and handles up to 6L. RO filter replacement charges vary by brand. A technician visit may add extra charges. 

Some brands bundle filters into one plan. For example, Livpure’s comprehensive plans cost ₹4,399 a year (online RO ACMC) and ₹6,599 (premium ACMC). Both feature two years of preventive maintenance, but only one filter replacement every year. 

Is it Cheaper to Buy or Rent an RO Purifier in Delhi? 

If you are staying 1-3 years, an RO on rent costs less than buying new. Rentomojo’s DriftGo features a multi-stage RO purification system with UV+UF technology. The rent is ₹14,076 on a 36-month plan. The plan covers filter replacement every six months and maintenance. 

Note: The prices vary. Check the Rentomojo app or website to see the latest pricing. 

The water purifier brands recommend replacing carbon and sediment filters every six to eight months. So, three years of ownership, including filter changes, may cost around ₹18,999. The real cost comparison depends on how long you plan to stay. Owning a water purifier is favourable for anyone who wants to stay in their own home and cover upkeep costs. For a tenant on a one-year agreement who may move within a year, an RO on rent is preferable.

Frequently Asked Questions

1. Which water purifier is best for home in Delhi? 

The best water purifier for home in Delhi depends on the TDS of the water supply. The level varies by locality. Delhi Jal Board supply has low TDS levels, and borewell water has higher levels. RO water purifiers suit high TDS, while UV+UF units are rated for TDS below 200 ppm.

2.  How to choose an RO water purifier? 

Choosing an RO water purifier for home starts with checking your water TDS levels and finding a purifier that matches the rated TDS limit. Then check the storage capacity, purification rate, and extra stages such as mineral, copper, or alkaline cartridges. 

3. What are the disadvantages of an RO purifier? 

The main disadvantages of an RO water purifier are rejected water, mineral loss, recurring filter costs and dependence on electricity. For example, Rentomojo’s DriftLux lists a 40% water recovery rate. Many RO models add mineral, alkaline, or copper stages to restore minerals lost during purification, and some brands bill AMCs separately.

4. What is the lifespan of an RO water purifier? 

An RO unit usually lasts 7-10 years with regular servicing and maintenance. Replace sediment and carbon filters every six months. On Rentomojo’s own purifiers, filter changes are included in all plans. 

5. Can I rent a Kent RO purifier in Delhi? 

Yes, Rentomojo lists Kent Pride Plus (RO+UV+UF+TDS) for ₹1,1999/mo on a 12-month plan and ₹1,175/mo on a 36-month plan. The non-RO purifier from Kent, namely, Kent Maxx (UF+UV), costs ₹679 and ₹665 on the same plans. 

6. Is RO water safe for kidneys? 

Whether RO water suits someone with a kidney condition is a medical question to discuss with a doctor. The World Health Organisation proposes no health-based guideline value for TDS in drinking water. Many RO purifiers, including Rentomojo’s DriftGo and DriftPro, add mineral or alkaline stages after purification.
