Which product is our top pick in this guide?
Our top pick is the Aquadyne RO Service Kit, whose listing names the Pure-it Classic G2 Mineral RO + UV and offers tele and video fitment support. If you want to know exactly what is in the box, the Nutronix kit lists a PP spun cartridge, carbon block, 75 GPD RO membrane, post carbon + UF membrane and a 4-watt UV lamp.
India’s BIS drinking-water standard, IS 10500, sets the acceptable limit for total dissolved solids (TDS) at 500 mg/L — relaxed to 2000 mg/L only where no better source exists — with an acceptable pH range of 6.5–8.5; a purifier’s job is to bring your source water within these limits. BIS IS 10500:2012 (opens in new tab)
Both are compatible kits, not made by Pure-it: the Aquadyne listing states it is neither manufactured nor endorsed by Pure-it. Before ordering, confirm the exact model name on your purifier's label — Pureit uses the Classic name on more than one purifier, and kits are model-specific.

Editor's read
Two things decide this purchase: fit and contents. Fit comes first — a kit made for another Pureit model will not help, so match the exact model name on your purifier's label. Then check what you are paying for: of the two kits here, only the Nutronix listing itemises its parts, while the Aquadyne listing states only that it is a compatible service kit for the Classic G2 Mineral RO + UV.
— Bikram, editor
Editor's take
Our top pick is the Aquadyne RO Service Kit because its listing names the exact purifier, the Pure-it Classic G2 Mineral RO + UV, and includes tele and video fitment support. If you want an itemised kit, the Nutronix lists every part; if only the membrane is due, the Vontron 75 GPD is sold on its own.

How we picked these filter replacements
Every pick on this page is matched to its exact Amazon India listing, and the specifications, warranty terms and features on each card come from that listing; a brand's own claims are attributed to the brand. We don't physically test the products in our guides, and we don't link to Amazon search results. Prices shown come from Amazon's data with the time they were fetched; the price at checkout can differ.
Our editorial process is one person — Bikram, based in Pune. The order of products on this page reflects our editorial ranking only. No brand paid for a place in this ranking. Each ranked pick earns us money only through its Amazon affiliate link — clicking through earns a small commission, your price stays identical.
Standards & sources
- BIS IS 10500 — Drinking Water Specification (opens in new tab) — India's drinking-water quality limits are defined by BIS standard IS 10500 — a purifier's job is to bring your source water within these limits.
- Bureau of Indian Standards (BIS) — product registration (opens in new tab) — Many electronic goods sold in India require BIS registration for safety; you can look up a product's BIS registration on the BIS portal.
Buying filter replacements in India — what to check
- Warranty:check that the listing states an Indian warranty and what it covers. Imported (grey-market) units may not be serviced by the brand's Indian service centres.
- Delivery and returns: Amazon shows the delivery date for your pincode and the return policy on each product page. Check both before ordering, especially if it is a gift or needed by a date.
- Keep the invoice: some brands ask you to register the product after purchase. Keep the Amazon invoice and read the warranty card that comes in the box.
What to Look For
- 1.Confirm the model first: kits are made for specific purifiers. The Aquadyne kit names the Pure-it Classic G2 Mineral RO + UV; the Nutronix kit names the Classic G2 in its title and "classic ro + uv" in its description. Check the model name on your purifier's label before ordering.
- 2.Genuine vs compatible: both kits here are third-party. The Aquadyne listing says it is neither manufactured nor endorsed by Pure-it, and uses the Pure-it name only to show compatibility.
- 3.Know what is in the box: the Nutronix listing names every part (PP spun cartridge, carbon block, 75 GPD RO membrane, post carbon + UF membrane, 4-watt UV lamp); the Aquadyne listing does not list its contents, so ask the seller before buying if you need a specific part.
- 4.Membrane only: if just the RO stage needs changing, the Vontron 75 GPD membrane is sold on its own. Its listing gives a 6,000-litre capacity and says it is used in RO purifiers, but does not name the Classic G2.
- 5.Installation: the Aquadyne kit comes with tele and video fitment support. If you are not comfortable opening the purifier, use a technician.
Frequently Asked Questions
Are these Classic G2 filter kits made by Pureit?
No. Both kits here are compatible third-party kits: the Aquadyne listing states it is neither manufactured nor endorsed by Pure-it and uses the name only to show compatibility, and the Nutronix kit is sold under the Nutronix brand.
What does a Classic G2 RO+UV service kit include?
It depends on the seller. The Nutronix kit lists a PP spun cartridge, a carbon block filter, a 75 GPD RO membrane, a post carbon + UF membrane and a 6-inch, 4-watt UV lamp. The Aquadyne listing does not list its contents, so ask the seller before buying.
Can I replace only the RO membrane in the Classic G2?
Membranes are sold on their own — the Vontron 75 GPD membrane here lists a 6,000-litre capacity. Its listing says it is used in RO purifiers but does not name the Classic G2, so match it to your old membrane before ordering.
How long does Amazon India take to deliver filter replacements?
Delivery time depends on your pincode and the seller. Amazon shows the delivery date for your pincode on each product page before checkout, so check it there for the pick you choose.
Are these filter replacements available with No-Cost EMI on Amazon India?
EMI and No-Cost EMI options depend on the product, the seller and your card. Amazon lists the options available for your payment method on the product page and at checkout.
Can I return filter replacements on Amazon if they don't work as expected?
Return and replacement terms are set per product and seller on Amazon.in. Check the return policy shown on the product page before you order, and keep the invoice for any warranty claim.
