Along with coping of its yearly terrible air pollution crisis, a Delhi-based Redditor has proved very skilful by coming up with a solution that can easily be termed as not only very effective but also very economical and perhaps even comparable to the expensive commercial air purifiers thus issuing a challenge to their dominance. The said purifier was built by a Delhiite for just ₹2,000 , which he posted about on Reddit and in no time resulted in going viral.
The surprising outcome? A phenomenal indoor Air Quality Index (AQI) decrease from a dangerous 380 to a “good” over 50 in less than 15 minutes even at the fan’s minimum speed. This clever trick gives instant and practical relief to people suffering from the city’s poisonous air, not only that, it also demonstrates that pure air does not necessarily have to be expensive.
Component Simplicity for Maximum Air Filtration
The main component of this easy and efficient homemade device is its simple and common parts. The maker, who posted the construction in r/delhi subreddit, disclosed the uncomplicated shopping list that resulted in this excellent air filtration system. At the heart of the device is the 150mm exhaust fan, which costs around ₹750, and serves as the motor to pull the air in.

The fan is, however, accompanied by a High-Efficiency Particulate Air (HEPA) filter, which is sold online for about ₹1,000 and is still a must-have item. The rest of the budget was allocated to basic electrical parts such as switch, regulator, wire, and very inexpensive construction materials such as cardboard and a glue gun for putting together. This application of simple parts forms an efficient high-volume air-purification system.
Cost-Effective Pollution Defense
The DIY purifier’s cost-effectiveness is very much in contrast to the market price of branded purifiers, which generally start from ₹10,000 and go up to ₹40,000. The Delhi resident, by rejecting the brand markups and unnecessary features, purely concentrated on the functional essentials namely air movement and particles capture. The device’s design was validated by the drastic fall in AQI from a dangerous level with strong health warnings to a safe and breathable range.
The builder even took an existing branded purifier as an AQI sensor for verification, thus confirming that their low-cost innovation was either better than or up to the mark with the commercial products. This viral success story is a signal of hope, encouraging people to control their indoor air quality by means of simple, replicable, and cheap DIY air purification methods.
