Sediment, carbon and membrane inspection at your doorstep — replaced only when the technician confirms it's needed.

Not every RO issue needs a new filter. A technician inspects your sediment, carbon and membrane filters first and tells you honestly whether replacement is needed — we don't replace filters as a default upsell.
If a filter is genuinely worn out or affecting water quality, it's replaced on the spot, with the old part shown to you and the new one's cost confirmed before work proceeds.
The technician inspects first — replacement is only recommended when actually needed.

Will you replace my filters even if they don't need it?
No. A technician inspects sediment, carbon and membrane filters first and only recommends replacement if it is genuinely needed. You'll see the condition of the old filter before agreeing to a replacement.
How often does an RO filter need replacement?
This depends on your water quality and usage, and is confirmed by inspection rather than a fixed schedule. Sediment and carbon filters are commonly checked every few months; the membrane lasts considerably longer under normal conditions.
How much does RO filter replacement cost in Kolkata?
Sediment filter replacement typically costs ₹200–₹400 and carbon filter replacement ₹250–₹500, with pricing confirmed at the time of inspection based on your specific model.
How do I know if my RO membrane needs replacing?
Signs include persistently high TDS in output water, noticeably slower flow, or a change in taste. The technician tests TDS and inspects the membrane to confirm before recommending replacement.
Can I get just an inspection without replacing anything?
Yes. The inspection and TDS test are part of the service call; you decide whether to proceed with any recommended replacement.
Are the replacement filters genuine?
Filters used are sourced for compatibility with your specific purifier model, and details are shared with you at the time of replacement.
