Improving indoor air quality with water-based air filtration system

This paper explains the design and development of a water-based air filter system for recycling and cleaning the air indoors; particularly in houses, classrooms and offices. The device is developed as the concerns for indoor air pollution has arisen and to introduce an economic and environmental friendly system for filtering air. The water-based air filter system includes a support base which provides portability to it, and also includes a tank being at least partially-filled with water and having an inlet through wall where polluted air is drawn in by an exhaust fan into the water in the tank and also having an outlet holes at the top to let out filtered air into the surroundings. Water is introduced in this design as it is the cheapest easiest source of cleaning element to find. It also helps in reducing the use of cartridge filter and material saving.
