RO Filter Prices & Replacement Guide for Nellore

Which filters your purifier needs, the honest price range for each, and how often they actually need changing on local water.

Typical filter costs in Nellore

• Sediment filter — ₹300 to ₹600. Catches sand and silt. Clogs fastest on borewell water.
• Carbon filter — ₹350 to ₹700. Removes chlorine, odour and bad taste before the membrane.
• RO membrane — ₹1,500 to ₹2,800. The main purification stage and the biggest single cost.
• UV lamp — ₹500 to ₹1,000. Only on RO+UV models, replaced once a year.

How often to change them

On Nellore water, sediment filters generally need changing every 3 to 4 months and carbon filters every 5 to 6. Membranes last 2 to 3 years in the city and inland west, but only 12 to 18 months on the coastal belt where salinity is high. Filters should be changed on condition after testing, not purely because a date has passed.

Are filters the same across brands?

Most domestic RO units take standard 10-inch sediment and carbon cartridges with a 75 to 100 GPD membrane, which are interchangeable across many brands. Some makers use sealed proprietary cartridges that only fit their own units and cost more. We confirm which type yours takes before fitting anything, and open the sealed packet in front of you.
