Buying the cartridges, not doing the replacement?
This guide lists which cartridges to buy. The step-by-step replacement procedure is on a separate page — How to Replace RO Water Purifier Filters — 6 steps, ~60 minutes, no plumber needed.
The Kent Grand Plus is a 7-stage RO+UV+UF purifier and it shares its cartridge family with the Supreme Plus and Elegant — one of the reasons it has one of the easier parts-hunting experiences in India. The replaceable consumables you actually deal with are: a sediment pre-filter (PP spun, ~6 months), a pre-carbon block (~6 months), a post-carbon polisher (~12 months), the 75 GPD RO membrane (12–24 months depending on TDS), and the UV lamp (~12 months or 6,000 hours). Kent keeps the housing threads proprietary enough that inline OEM sets snap in cleanly, while compatible cartridges fit with a little care. A full DIY set refresh runs ₹1,000–₹1,800 if you stick to Vontron/Wellon compatibles, ₹2,000–₹3,500 if you buy Kent-original. An authorised service visit for the same work is usually ₹1,600–₹2,500 before parts, so DIY saves real money if you're confident. One honest red flag: if your TDS meter reads above 80 ppm after the post-carbon, the RO membrane is the real issue, not the pre-filters — swapping only sediment and carbon won't fix bad output.

Check Latest Price on Amazon →What to Look For
- 1.Identify your exact variant before ordering. The Grand Plus sold in 2020–2024 uses slightly different housing than the 2025 refresh. Look under the front flap for the model sticker (e.g. 11112, 11152). Kent's OEM boxes list compatible model numbers — match them before paying. If you order blind off a listing that only says "Grand series," you may receive housings that don't thread onto your unit.
- 2.OEM vs compatible — the honest trade-off. Kent-original cartridges are QC-consistent, come with Kent's warranty paperwork, and cost roughly 1.8–2.2× the price of Vontron, Wellon, or Aquaboss equivalents. Compatibles from reputed brands (Vontron especially) perform within 5–10% of OEM on RO membrane rejection, but you lose any remaining AMC warranty and there's no recourse if a housing leaks.
- 3.Installation safety — do this right. Turn off the inlet water valve and unplug the unit before touching anything. RO systems hold residual pressure: open the dispenser tap to bleed it before unscrewing any housing. Drain the tank if you're replacing the membrane. Wear gloves — old carbon filters stain. Dry-fit the new cartridges, then tighten housings by hand only. Never use a wrench on plastic housings.
- 4.Warranty implications are real. A Kent AMC is void the moment non-OEM parts go in. If your unit is under 1 year old or under AMC, pay for genuine cartridges — the price delta is less than a single service visit. If the unit is 4+ years old and out of AMC, the warranty argument doesn't apply and compatibles are reasonable.
- 5.TDS and regional factors matter more than the calendar. Coastal cities (Chennai, Mumbai, Vizag) and hard-water zones (Pune, Bengaluru borewell) push membranes harder — plan 12-month membrane changes rather than 24. Soft-water cities (parts of Delhi on Yamuna supply) often stretch to 24 months. Buy a ₹200 TDS meter and check input + output monthly; that's a better replacement signal than guesswork.
- 6.When to call a technician instead of DIY. If water is leaking from the top of a housing after install, if the UV lamp won't seat, or if output TDS stays high after a new membrane, stop and book a service visit. The three most common DIY failures are: cross-threaded housings, O-rings pinched on reassembly, and membrane installed reverse. None are catastrophic but all require a technician to fully reset.
