Clean Air is not a Luxury

Our tests show that the DIY 1.0 can remove up to 82% of PM2.5 particles from a 150sqft room, all for BDT 4,500.

How does it compare to expensive purifiers?

We tested this simple DIY purifier against some of the biggest brands on the market, and found that the simple DIY performed almost just as well as purifiers costing over 20 times as much!

Does it really clean the air?

Tom the founder of Smart Air and a professor at the University of Chicago tested this using a laser particle counter. What he found was that even low-cost filters and fans can provide clean air. Watch this video to see the test he did.

How often should I change my filter?

Because of severe air pollution levels in Bangladesh the filter lifetime is less than in other countries. We recommend replacing your filter after 2 months of use (at 8 hours a day) at the latest. That’s maximum 650 hours in total; this is the amount of time you can run your DIY 1.0 air purifier before needing to change your filters. However, you should still check your HEPA filter at regular intervals. Use our filter lifetime calculator to determine when to change your HEPA filter.

We know that buying new HEPA filters is a significant recurring cost, so we do our best to keep prices low.

How can I protect myself from the high air pollution levels in Bangladesh?

Bangladesh, and especially Dhaka, has one of the highest air pollution levels in the world. During the winter season it is common for AQI to average between 200 (very unhealthy) and 300 (hazardous). Outdoor air pollution drastically affects air purifier performance – even when used indoors. When outdoor air pollution is bad, purifiers achieve a smaller percentage reduction and it becomes harder to reach safe levels indoors. In order to breathe safe in Bangladesh we recommend “overpowering” the air pollution by: (1) using a second purifier, or (2) buying a machine that is rated for an even bigger room.
