The real cost of clean air: a 5-year comparison
The real cost of clean air: a 5-year comparison
When most families buy an air purifier, they look at the MRP. Rs 12,000. Rs 18,000. Maybe Rs 25,000 for a premium brand. That number feels like the cost.
It isn't.
The hidden cost: filters
A standard HEPA filter in Delhi conditions lasts 15–30 days during winter. Each replacement costs Rs 2,500–4,500 depending on the brand. Over a year, that's Rs 13,000–26,000 in filter costs alone.
Over five years:
| Competitor A | Competitor B | Novayu | |
|---|---|---|---|
| Device | Rs 18,000 | Rs 25,000 | Rs 27,500 |
| Filters (5yr) | Rs 45,000 | Rs 35,000 | Rs 8,000 |
| Maintenance | Rs 8,000 | Rs 5,000 | Included |
| Total | Rs 71,000 | Rs 65,000 | — |
Why our filters last longer
It's not magic. It's engineering.
Our four-stage system puts a 15-year washable pre-filter ahead of the HEPA. This pre-filter captures 93–96% of large particles before they reach the HEPA membrane. The HEPA handles only the finest particulates — and lasts 20–28 months instead of 15–30 days.
The subscription model
At Rs 499 per quarter, your replacement HEPA ships automatically — 18 days before your device predicts you'll need it. No manual ordering. No forgetting. No breathing through a dead filter.
The total five-year cost, including the device and all consumables: —.
That's less than half of what most families currently spend — and they get better air quality, because the filter is never dead without their knowledge.
