Review on Eco 420 Personal Air Filter: Aluminum Air Purifier with HEPA and Carbon Filters for Superior Air Filtration. Eco-friendly Solution to Save Money and Reduce Plastic Waste. by Gregory Popo

I hate plastic waste so I thought I found what I needed. Unfortunately, it was more expressive and generated just as much waste as the Smoke Buddies I used. Bought on 11/12. I breathe deeply 5-7 times a day. That's about 150-200 breaths. Earlier this week it was getting very difficult to push air through so I ordered replacement filters, 2 packs for about $16. Now 2 days to replace the filter and it's already clogged. that's a maximum of 20 breaths. Smoke Buddies last between 3 weeks and a month. I'm not sure I'll come out on top when it comes to creating less waste or saving money. I think I'll come back to my idea of using my 3D printer to make my own durable reusable filter.
