I made one using 8 filters. When doing merv-13, the filters resist a lot of airflow to stop allergens from getting through. Yes you can use one filter, but 4 is 4x the airflow and 8 is 8x the airflow. Im sure there is a limit based on the fan's power. You can also store things inside. A sheet around it makes it no longer ugly. Extra money can buy a quiet fan.

Its a great deisgn. Far better than the $500 hepa filter. Will last much longer and has a higher cvm rating. I paid $12 per filter and $25 for the fan.
