Of cost is AFTER purchase
💡 Reasonable running costs. Still, ask for the filter price list in writing before buying - that is where brands differ most.
Typical yearly filter sets: budget RO ₹2,000-3,000, premium RO ₹3,500-6,000. UV-only units run far cheaper (lamp ~₹500/yr).
Frequently asked questions
Why do filter costs differ so much?
Proprietary filter designs lock you to the brand's spares. Before buying, ask for the printed filter price list - it varies from Rs 1,500 to Rs 6,000 a year for similar machines.
Is an AMC worth it?
If the AMC includes all filters and membrane, usually yes. If it only covers labour, skip it and pay per visit.
