Invented by Richard Corsi and Jim Rosenthal, the Corsi Rosenthal Box is an effective air purification system. Air is sucked into a HEPA filter to remove droplets containing viruses in the air.for you Air leaks and incorrectly oriented filters will make the system less effective, so it is important to pay close attention to orientation.

Here are the materials you will need for this project: packing tapefour MERV-13 air filter, 20-inch box fanthe box containing the fan, and utility knife.

How to make a portable DIY air purifier

To assemble the box, lay the filter flat, with the arrow pointing toward you, and sew the inside edges of the filter together and tape the filter. Once the filter is sewn along the edges, stand it up and tape her last two edges together. At this point, all arrows on the filter should point inwards. Go around the outside of the box and seal the seams with duct tape from the outside. Make sure the seams are tight-Closed and strong.

Next, Add a floor to your box by placing the box the fan was in at the bottom of the square you made and seal the seams there just like you did on the four sides. It fits snugly, but if there is a gap, tape it up.This will give you the first 5 side of your box.

Then put a fan on top so that the airflow is out of the box. If you’re not sure which direction your fan is pointing, turn it on and see which direction the wind blows. At this point there may be some gaps as the fan may be slightly curved at the corners, use a small piece of cardboard and cut to fit the gap with a utility her knife To do.Then tape them together and seal the edges good. Then use tape to seal the entire fan as well as the sides and bottom.
