Delhi man builds DIY air purifier for Rs 2,000 — does it beat the smog?
A Delhi resident claims a DIY air purifier under Rs 2,000 cut indoor AQI from ~400 to 50 in minutes. We break down the setup and what it could mean for affordable clean air.
Delhi is grappling with toxic air as winter smog returns. With demand for air purifiers rising, a Delhi resident posted a home-made fix that costs under Rs 2,000 and claims dramatic results.
He built the purifier from a 150mm exhaust fan (Rs 750), a HEPA filter from Amazon (Rs 1,000), a switch, regulator and wire (Rs 65), and cardboard plus a glue gun (Rs 150). Total under Rs 2,000.
According to his post on Reddit under the handle shukrant25, he says the device cleaned his room’s air to an AQI of about 50 from nearly 400 in under 15 minutes, and that it outperformed a Philips purifier he owns.
The claim has sparked online chatter and drawn interest from people looking for affordable solutions on severe pollution days. Performance can vary based on room size, sealing, and filter quality; a DIY purifier can help, but results are not guaranteed and safety considerations with electrical devices matter.
Delhi’s air quality frequently crosses into the severe range in winter, prompting authorities to weigh measures to curb emissions and protect public health. Whether this DIY approach becomes a trend or remains a niche option, it highlights a broader question: can low-cost ideas offer real relief for households under smog? For now, readers are encouraged to test, compare, and keep safety and official guidance in mind.
