There are a few main parts that I would like to introduce for our air purifier. First, the outside air is suck in from the input pipe. The outside air is suck from this pipe. 

​

The air sucked in that goes through the two filters that are included inside the purifier. It is first sent through the HEPA filter, which is able to purify 99.97% of air particles by rapidly sucking air in, and removing dust particles from it.

​

After the air particles go through the HEPA filter, it will then arrive to where the active carbonated filter is. The active carbonated filter pulls in more dust, and also pulls in VOCs, Volatile Organic Compounds. It is also able to take care of gas, removing odor from the air.

​

After it has gone through both the filters, it will reach the output pipe where the air is released. The purified air is released from this pipe after all the steps before are completed and after air has been purified. 

​

All of these steps cannot be completed without mechanical help, which will move the air particles through these steps quickly and effectively.
