Simple filter, done in 20 seconds.
Good filtration and airflow.
The inside basically acts like a spring, so you can roll it together and it will expand again naturally.
Here's how to do it.
Step1:
Fold in a tiny piece at the edge

Step2:
Roll it until you have a pretty tight spiral at the end

Step3:
You roll in that spiral hold it between your thumb and index finger on one side and hold the rest of the strip from the other side then start pushing the strip together so your thumbs close and make that nose you see.

Step4:
Roll it up and squeeze it together so it looks kinda like this

Step5:
Roll the little spiral and the spring inside the rest of the strip

Finished filter:

I hope people don't find it too difficult.
