Hepa filter for enclosure

Having decided to try printing more technical materials, I built a fence to close my Prusa. having to print in a room of my house, I worried about finding a way to filter emissions during printing, on the market I found Hepa filters on 3D printing sites but they are very expensive. so I thought of using a Hepa filter from a small air purifier on the market and adapt it to my enclosure.


The aspirator filter is optional, it is only needed if your case is well sealed and does not allow air exchange.
for a case such as built with ikea Lack that has different slits, the suction filter is not needed.
