How to Make an Air Filter / Air Purifier | DIY / How To

I created a one-minute homemade air cleaner out of a box fan and a furnace filter; the thicker the filter, the greater the filter area and air flow. I need something to clean the air in our house, and this homemade air cleaner works great. This setup is also useful for reducing dust in the room during home demolition and remodeling. A space of 20"x20" will suffice, but the larger the better.

I hope you learned something from watching my videos! I am currently doing this part-time in the form of a hobby so it would mean the world if you could give this video a like and subscribe for DIYs and Vlogs. Until next time. Thank You!
