Review on 🌬️ Enhance Air Quality with FilterBuy 16X25X1 Pleated Furnace Filter Filtration by Lancy Rakesh

Idea because air can't filter through them that easily. Instead, I tried to design a cardboard fan box, which worked very well up to a point. - I have a powerful fan that can clean the floor of a house or apartment very quickly when the windows are open (if any) and I used corrugated cardboard, tape and a utility knife to cut out a shape for it and a filter shape and formed a tunnel chamber that was virtually airtight. The result was loud and big, and I couldn't convince my workers to let me try; They didn't give me much encouragement, so I didn't try to push it. My favorite source for this is Wirecutter (in New York times), and I ended up following their recommendation and buying a $200 unit from Coway. But I would like a better solution. There are only compromises and I need to figure out how the best air systems work (like in a hospital) but I suspect they use more power and make more noise and probably should be on the roof.
