"Humdinger"It is fairly obvious from the way the gold filter is attached and the choice of words used that JoSoo is associated with a vendor in China and most likely is from there.
The Xin Yong Shi filter shown is an excellent filter. Look at the number of threads in the end caps compared to Tuxing brand gold filters. This one has holes in the end caps which make the end caps much easier to remove if a rod is used for leverage. Cut the included round tampon filters into end spacers and use another 1/2" piece as an interior spacer. Zeolite 13X desiccant and activated charcoal from any pet supply store are used to filter out moisture, odors, and impurities from the air. It is easy to roll up a clear plasitc transparency sheet to line the filter wall to protect it from the dreaded acid leeching gremlins. I posted a thread a couple of months back on how to make the liner. It is easier, cheaper, and faster to make than PVC with o-rings. It creates a tighter air and moisture seal. My experience has been that no liner is actually necessary. It is strictly a peace of mind accessory for extremely cautious users.
