DIY a mask with replaceable N95 filters in 10-30 mins

I couldn't get the face mask to protect myself against the coronavirus , hence I built two masks with different materials. I can use the Merv 13 filters I have (from the HVAC).
A 20" x 20" HVAC filter can make 150 pieces of the replaceable N95 filters.
It is very easy to do and I would like to share it with you.

I love this. Great of you to repurpose things like you do. I always look to reuse and repurpose things. I made a small stand for figurines out of some scrap wood and a 'disposable' foam cooler
I am looking to try and get some old coroplast from large signs to make a boat from one of your great designs.
