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 Kyle Beaner

I used to buy Smokebuddies and about half the time it would clog within a week or two. However, this Eco Four Twenty filter works great. It's made of aluminum and looks solid. It can be disassembled for cleaning and replacing filters, which is excellent and environmentally friendly compared to disposable splofs. This will outlive any filters I've used in the past. Great job Eco Four Twenty! EDIT: (12/30/18) It's been a month since I got them. The original filter only lasted about 2 weeks before it started clogging and I ordered several replacement filters. Replaceable clogs for less than 100 puffs. So far I am not satisfied with the durability. EDIT 2: A day later the owner of Eco Four Twenty contacted me and offered me some options to compensate for my short lived filters. He takes customer service seriously and I thank him for reaching out and making sure I am happy with my purchase. At least that's what makes them regular customers for me.
