Review on BUFF Standard Filter Tube Black by Jay Blo

This is a good product idea with horrible execution. The replacement filter is paper thin and will not stay in place. The opening of the filter bag is at the top of the neck, which means you grab the tube right at the opening when you pull the tube up and down, which is what you do all the time while skiing. filter bag. Since the filter is very thin and nothing will hold it in your pocket, it will wrinkle, curl, fold and even stick out of the hole. The filter bag should have a side opening and be so small that it cannot easily fall out. The filter itself must also have great rigidity so that it does not lose its shape. Standard PM2.5 filters can even be strong enough to last better than buff filters. Almost more disappointing than the filters is that the neck material has lost its elasticity even after a few hours. Now it's loose enough that it doesn't fit snugly around my face/nose. It was the right size when I first received it. I've had regular buff bulbs and cheap imitations for years and they don't stretch that much. If they just used regular stuff it would probably be better than this bespoke design. I really expected more, especially at $50 considering the neck plus a bag of replacement filters. The filters are closed and useless because I'll probably never wear it enough to use the multiple filters that come with the neck.
