THE SHORT ANSWER
How much does a fresh-air (ERV) system cost in India?
Fresh-air (ERV) systems bring filtered outdoor air into a sealed home. One Indian supplier lists ERV units at ₹45,000 to ₹90,000 for a 2BHK and ₹80,000 to ₹1,60,000 for a 3 to 4BHK or villa, plus ₹10,000 to ₹40,000 installation, though the page footer is dated December 2023. Compare this with room purifiers and filter running costs.

Define the problem before selecting equipment
Record the rooms of concern, outdoor conditions, occupancy and potential indoor pollution sources. Discuss how the space is ventilated and whether a portable unit or an HVAC-integrated approach is feasible. Avoid assuming a single device will solve every air-quality problem.
Match equipment to the room and routine
Ask the designer to explain capacity at a usable fan speed, expected noise, filter costs and replacement availability in India. Check where the unit will sit and how doors or open-plan areas affect the intended coverage. An app display is only as useful as the underlying measurement and maintenance plan.
Make upkeep part of the quotation
Agree who inspects filters, how replacement intervals are determined and how the household records changes. Keep claims about medical outcomes out of the purchase decision unless supported by qualified advice for the particular situation.
Current information to check
EPA guidance treats filtration as a supplement to source control and ventilation, not a complete replacement. Compare those measures together rather than relying on a purifier alone.

Questions answered
How much does a fresh-air (ERV) system cost in India?
Astberg Ventilation lists ERV units at ₹45,000 to ₹90,000 for a 2BHK (150 to 250 CMH) and ₹80,000 to ₹1,60,000 for a 3 to 4BHK or villa (300 to 500 CMH), with installation often ₹10,000 to ₹40,000. The page is titled 2026 but its footer says last updated 29 December 2023, so confirm current prices.
Purifiers or a fresh-air system?
Room purifiers clean recirculated air in one room. A fresh-air system ventilates the whole home with filtered outdoor air and needs ducting. Many homes use both; decide per room.
What are the running costs?
Filters, electricity and servicing. Ask for the filter type, replacement interval and price in writing before choosing.
Can clean air systems be automated?
Yes, with air-quality sensors that switch purifiers or ventilation on schedules or thresholds. Confirm the integration with your automation system before buying.
Does a fresh-air system work with ACs?
Yes. An ERV recovers some cooling from the outgoing air, but ducting, the AC layout and condensation must be coordinated. Ask the HVAC designer and the ERV supplier to agree the design together.
How do I know if the air system is working?
Fit indoor air-quality sensors for PM2.5 and CO2 and check them before and after installation. Ask the installer to show readings at handover.
