Make computer into air purifier?

[1zacster]

I was wondering could I just like screw (or even tape) replacement filters from an air purifier over the intake fans on my system to clean the air in my room. Its on almost 24/7.

The fans probably don't move enough air for it to do anything. Also, it will restrict the airflow into your case and your PC will get hot.
