In recent years, air pollution has become a major threat to survival of mankind. Looking at the current problem, biological air purifier would deliver a smart solution to circumvent the problem of indoor and outdoor air pollution caused due to motor vehicles, occupational exposure, cigarette smoke and industrial emissions in particular and will also focus on utility of the air purifier in reducing exposure of public to air pollutants. The team has designed and fabricated a prototype of biological air purifier- “Biosmotrap” comprising of compact carriage assembly with replaceable adsorbent packed in biodegradable pouches or wrappers by means of support meshes and clamping structures and further attached to vents, exhaust or any outlet from where gases are released in any process.

The microbial biomass and/or natural bio-materials were employed in the form of solid porous material as an adsorbent. The adsorbent is configured to adsorb air pollutants like smoke, aerosols, particulate matter, flue gases, soot or other air pollutants. The shelf life of adsorbent depends on the concentration of air pollutants from the source point. It reduces the levels of organic as well as inorganic pollutants from the air. The onetime cost of carriage assembly is incurred with each biological air purifier. It can be reused for longer duration until it breaks or needs repair. Also, with the use of recyclable adsorbent material the cost per air purifier is lowered by making it affordable to everyone. This lowers the overall cost of maintenance when compared to conventional air purification technologies and increases its utility by encouraging public at large to use such devices. The fabricated prototype is easy to operate, cost-effective, recyclable and environmental friendly.
