I like a real filter, I hate that cheap valve that breaks easily. I bought 5 filters, two 206s and three 406s, currently only use 406s and had to buy two of these because I broke my last of two and needed a replacement. So I broke 3 in total and haven't used them for more than a year since May 2019. They break if you try to reinstall them after cleaning. Sometimes it helps to open up the filter, which lets in some water (or a ton of crap if you're not careful), or when removing it, push the lever down to let the water in and relieve the air pressure.
