Indoor Air Filter Made by CTEE Team

Indoor Air Purifier can clean thin dust inside a 150 sft room within 30 minutes. Indoor air purifier for asthma, wheezing, and shortness of breath caused by particulate matter (2.5 microns, 5, 10 microns) in a country with air pollution. Foreign high-tech products are very expensive. We have it comparatively cheap.
I made this device from Shalbrikkho 2 years ago. This time I made it again on the occasion of the Department of Environment fair. I could not give it to anyone before. Many people have less space in their homes, many people thought the price was high, and we also had some problems making it. I hope it can be given now. Since the work of Shalbrikkho is divided, this air filter will now be made by the Climate Technology Education and Entrepreneurship project.
There is a Facebook group of Climate Technology Education and Entrepreneurship (CTEE). You can join if you want.
