Pureit Classic G2 RO+UV Filter Replacement (2026)

Third-party membranes typically fit the Classic G2 housing physically, but Pureit's warranty terms require Genuine GermKill Kit (GKK) parts purchased through authorised channels. More critically, the G2's flow-sensor-based cartridge counter will not reset with a non-genuine kit, leaving the service indicator inaccurate. This can result in the unit locking out early or — in the opposite case — continuing to run past safe purification limits.

The GermKill Kit (GKK), which includes the pre-filter, carbon cartridge, and germkill element, is rated for roughly 1,500–2,000 litres and typically needs replacement every 3–6 months at standard household use. The RO membrane lasts longer — around 4,000–6,000 litres — but degrades faster in hard-water regions (TDS above 400 ppm), common in Delhi NCR, Rajasthan, and parts of Maharashtra.

No. Swapping the GKK cartridge does not trigger an automatic reset on the Classic G2. You must manually press and hold the reset button for 3–5 seconds after installation. Skipping this step is the most common DIY complaint — the indicator continues counting from the previous cycle and can cause an early lockout, or worse, lets the unit run past the next safe service point.

Pureit rates the Classic G2 GKK at approximately 1,500–2,000 litres per set under standard conditions. At a typical Indian household draw of 10–15 litres per day, that works out to around 3–5 months of use. Households with municipal source water and TDS below 300 ppm will reach the higher end; those on borewell or tanker supply — especially during summer or post-monsoon when turbidity spikes — should expect closer to 3 months.

• Key factors: Confirm you have the Classic G2 — not the original Classic or the Classic Nova. G2 specifically refers to the 2021+ revision with the digital indicator panel. Part compatibility between Classic G2 and original Classic is ~80%; different housing generations exist. Order from listings that explicitly call out G2 to avoid thread mismatches.
• HUL genuine vs compatible — the indicator reset is the real decision point. HUL's pricing is less aggressive than Kent's or Aquaguard's, so the premium for genuine is smaller (typically 1.3–1.6× not 2×). If the counter-reset matters to you (it will eventually cut off water flow), either buy genuine + call for reset, or accept that compatibles mean a paid service visit yearly.
• Installation notes. The Classic G2 is a front-access unit — flip down the front flap, unscrew each housing anticlockwise. Drain through the dispenser first (tank holds ~7 L, takes 2 minutes). Pureit housings are slightly narrower than Kent's — overtightening splits them. Hand-tight + a gentle quarter-turn only. The UV lamp is horizontally mounted behind the post-carbon.

Amazon Prime members in metros (Mumbai, Delhi, Bangalore, Pune, Chennai, Hyderabad, Kolkata, Ahmedabad) typically get 1-2 day delivery. Tier-2 cities take 3-5 days. Remote pincodes (parts of North-East, interior Himachal, smaller towns in MP and Odisha) take 5-7 days. For filter replacements, we recommend verifying delivery date on the Amazon listing before checkout — bulkier water purifiers items occasionally take longer than the displayed Prime estimate.

Most products in the ₹950 – ₹3,100 per set range qualify for No-Cost EMI on Amazon India when you check out with a credit card from HDFC, ICICI, Axis, SBI, or Kotak Mahindra. Some debit cards from these banks also work. The exact EMI options appear on the product page after you select a payment method — typically 3, 6, 9 month no-cost terms for ₹950 – ₹3,100 per set, with longer 12-24 month terms available at small interest. Amazon Pay Later is also an option for orders under ₹60,000.

Most water purifiers products on Amazon.in have a 7-10 day return window from delivery date for replacement or refund, provided the item is unused and in original packaging with all accessories. Personal-care and consumable items are typically non-returnable once the seal is broken. For appliances and electronics, the manufacturer warranty (usually 1-2 years) covers defects beyond Amazon's return window — register the product with the brand within 7 days of delivery to lock in the warranty start date.
