A Delhi-based Redditor has built a DIY air purifier using simple and affordable items, sharing in a Reddit post that it managed to bring down the air quality index dramatically in just minutes.

“I built my personal air purifier for 2000 INR,” the caption of the post reads.

DIY purifier shows results:

Using a 150mm exhaust fan, a filter purchased online, and basic electrical components like a switch, regulator, and wires, the homemade device costs roughly ₹2,000 to assemble.

The Redditor reported that the air purifier could reduce the AQI from 380 to below 50 in under 15 minutes, even when running at the fan’s minimum speed.

The system was tested using another air purifier in the background as a reference sensor, showing that the DIY setup performed remarkably well.

Such a simple yet effective solution has caught the attention of many online, especially given the rising air pollution levels in Delhi.
