Our project was the result of in-depth research on air quality, especially in third world countries, where air filters are too much of a luxury. Even with the harsh conditions, for the citizens with low income, they might not be able to buy actual masks with filters embedded on them. Therefore, it is necessary to develop an air filter with the results obtained from the last experiment to create a highly effective, biodegradable, and cost-effective air filter. The latest experiment depended on the effectiveness of different household items. The first experiment focused on carbon dioxide with the combustion of wood through measuring the pH value using hydrolysis. Also, the last two experiments used two different air quality sensors to accurately identify the most effective combinations of cost effective house hold items in filtering air. The material can be used to create an actual filter with a lower price. This will be the final step in building a more effective and cost-efficient air filters favorable for all people with various income levels. Three different experiments have been conducted, one which measures the filtration of gaseous pollution and pollutants up to PM 2.5. After conducting three different experiments utilizing numerous methods for testing biodegradable alternatives of the materials used in the combination of household items as filters, they all shared the same conclusion of aloe, carbon, tissue paper, and seaweed cotton cloth being the most effective filter combination.
