Quick Answer
Our top pick is Aquaguard Genuine Enhance RO+UV+UF Filter Service Kit — Best OEM 3-cartridge choice for AMC-covered Enhance units.
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 Aquaguard Enhance RO+UV+UF is a mid-premium Eureka Forbes model with a 7-stage treatment train: sediment, pre-carbon, chemi-block, RO membrane, post-carbon, UV, and UF. Replaceables are sediment (~6 months), pre-carbon and chemi-block (~6 months), post-carbon (~12 months), 75 GPD RO membrane (12–24 months depending on TDS), UV lamp (~12 months), UF cartridge (~24 months). Genuine Aquaguard Service full cycle ₹2,200–₹3,400 including mandatory service visit. DIY with compatibles ₹1,200–₹1,900. Honest red flag: the Enhance runs a DC booster pump that is sensitive to pressure changes. If you install a compatible membrane without ensuring correct housing pressure (hand-tight + quarter turn), the pump overworks and can fail out of warranty — a ₹4,000+ mistake. Follow the pressure guidance in the unit's service card carefully.
How we picked these filter replacements
Every pick on this page started from real shopper questions, not Amazon's bestseller rankings. We exclude listings where reviews look incentivised — the patterns we screen for are sudden review spikes timed with coupon launches, brand-comparison templates copy-pasted across multiple variants, and listings under a year old with fewer than 50 organic reviews. Bestseller-tag products in narrow subcategories often game a small basket; we prefer products with deep, stable review history that survived seasonal surges.
Pricing on this page reflects realistic Amazon India retail. We ignore one-day flash deals, Prime-Day-only discounts, and stabilised retailer-only coupons that don't hold for someone shopping on a normal Tuesday. The ₹1,200 – ₹3,400 per setband is what you'll actually pay if you walk into this listing today, not the cherry-picked best-discount value.
Our editorial process is one person — Bikram, based in Pune — researching water purifiers products against Indian use-case constraints (voltage variability, hard water in many cities, monsoon humidity, smaller flat sizes than Western default). The order of products on this page reflects our editorial ranking only. We do not accept paid placements, sponsored slots, or PR-pitched products. Our only commercial relationship is the Amazon affiliate link — clicking through earns a small commission, your price stays identical.
Buying filter replacements in India — what to know
- Indian retail vs imported products: Most filter replacements listed here have official Indian distributor warranty. Imported (grey market / parallel import) units are sometimes cheaper but carry no Indian service-centre warranty — for water purifiers, that gap is meaningful since service infrastructure varies sharply between metros and tier-2 cities.
- Voltage and electrical compatibility: Indian mains is 230V at 50Hz with notable fluctuation outside metros. Most filter replacements in this category aren't voltage-sensitive, but verify the product page mentions Indian voltage compatibility before importing or buying grey-market units.
- Delivery realities: Amazon India Prime delivery in metros lands in 1-2 days; tier-2 cities 3-5 days; remote pincodes 5-7. For festive periods (Diwali week, Raksha Bandhan, year-end), even Prime delivery slips by 1-2 days due to demand surges. Build that buffer into your purchase timing if the filter replacements is for a specific date.
- Return window math: Standard Amazon India return window is 7-10 days from delivery, not from purchase or unboxing. For gifts and items received before the actual occasion, the return clock starts on delivery — order closer to your need-by date so the return option remains live if the product disappoints.
- Warranty registration: Most water purifiersbrands require online warranty registration within 7-15 days of delivery. Skipping this step often means the warranty period defaults to the manufacturing date (which can be months earlier) instead of your delivery date. Register on the brand's website with your invoice number — takes 2 minutes, saves a potential 1-3 month warranty gap.
- Stabiliser / surge protection: India's grid sees more voltage events than most product engineering tolerances assume. For filter replacements with electronic components, the 6002–12003 additional spend on a quality stabiliser pays for itself the first time it saves you from a power-surge replacement.

Check Latest Price on Amazon →What to Look For
- 1.Confirm the variant. Aquaguard Enhance was shipped as RO+UV, RO+UV+UF, and RO+UV+MTDS — cartridge counts and fit differ. The UV+UF variant is the most common. Model sticker is on the rear-bottom panel. Order listings that explicitly say "Enhance RO+UV+UF" — other labels can ship thread-incompatible housings.
- 2.Genuine vs compatible. Eureka Forbes genuine cartridges preserve AMC and have consistent chemi-block quality. Compatibles from Vontron, Aquadart, and Konvio Neer fit and perform acceptably on the filtration stages; the chemi-block grade is the biggest step-down. If your input water has obvious chlorine or chloramine taste, stick with OEM chemi-block even if other stages go compatible.
- 3.Installation specifics. The Enhance has a side-access cartridge bay (not front). Unlatch the right-side panel, unplug the unit, drain through the dispenser, unscrew each housing anticlockwise. The UF cartridge is horizontal in most Enhance units — note orientation before removal. Hand-tight + 1/4 turn with the supplied wrench; never overtighten, especially on the DC-pump-adjacent housings.
- 4.AMC reality. Aquaguard Enhance AMC is ₹3,000–₹5,000/year depending on city. DC pump failures are the most common expensive out-of-warranty repair (₹3,500–₹4,500). If your unit is 1–2 years old and you're ambivalent about DIY, the AMC is a reasonable insurance purchase. Past year 3, DIY generally wins on unit economics.
- 5.UF cartridge — the forgotten stage. The UF hollow-fibre cartridge at stage 7 is frequently skipped during DIY because it's buried behind the UV assembly. Neglecting it beyond 24 months causes bacterial regrowth in the post-UV line. Don't skip this stage when doing a full refresh even if it's tempting.
- 6.When to call Aquaguard Service. If the e-RO-cleaning indicator is permanently lit after a DIY swap, that counter needs a dealer reset. If the pump makes a high-pitch whine after install, you've overtightened the post-carbon housing. Loosen 1/4 turn and retest; if the whine persists, call service — whine + overtightening stresses the DC pump diaphragm.
