Pureit Classic G2 RO+UV Filter Replacement (2026)

How we picked these filter replacements

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 47516–95031 additional spend on a quality stabiliser pays for itself the first time it saves you from a power-surge replacement.

What to Look For

• 1.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.
• 2.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.
• 3.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.
• 4.Warranty — Pureit's is straightforward. Standard 1-year warranty on the unit, no AMC mandated. DIY swaps don't void the warranty unless you break something demonstrably. The unit's cartridge-counter lockout is a commercial feature, not a warranty one. You can bypass it with a paid reset visit or continue using compatibles and accept periodic lockouts.
• 5.TDS performance. The Classic G2's membrane is specced for input TDS up to ~2000. Beyond that, rejection drops faster than premium units. If you're on borewell with input TDS > 1500, plan 10–12 month membrane changes (not 18–24). Consider adding a 5-micron inline sediment pre-filter before the unit inlet — it extends membrane life meaningfully.
• 6.When to stop DIY. If the Classic G2 won't dispense after a cartridge swap and the front indicator is red, the counter has tripped — you need a Pureit Service reset. No amount of cartridge fiddling fixes this. If water comes out cloudy after new carbon, run 15 L through to flush carbon fines before drinking.
