Imagine you are an engineer, and you are trying to design an air filter that will successfully reduce the amount of air pollution being released into the air by a factory. You need to consider constraints that will limit your design as well as a criteria that will be used to judge the successfulness of your design

Constraints:

- Cost: The air filter must be cost-effective for the factory to install and maintain.
- Space: The size of the air filter must be practical for the factory's space limitations.
- Efficiency: The air filter must effectively reduce the amount of air pollution being released into the air.
- Durability: The air filter must be durable and able to withstand the conditions of the factory environment.

Criteria for successfulness:
- Reduction in air pollution: The air filter must successfully reduce the amount of air pollution being emitted by the factory.
- Cost-effectiveness: The air filter must be cost-effective for the factory to install and maintain.
- Energy efficiency: The air filter must be energy efficient and not consume excessive amounts of electricity.
- Durability: The air filter must be durable and have a long lifespan.
- Ease of maintenance: The air filter must be easy to clean and maintain to ensure optimal performance.
