If you frequently do soldering work indoors, this activated carbon filter is a must - have! It effectively absorbs solder smoke, leaving your indoor air fresh and clean. Measuring about 13 x 13cm, it's incredibly easy to trim with scissors or a utility knife. We quickly cropped one to fit our Miniature Desktop Fan. With a thickness of 9mm, it can slide into most'standard' solder smoke filters. Each purchase comes with one piece.

Using this carbon filter is easy. First, check if the filter needs trimming to fit your solder smoke absorption device. You can use scissors or a utility knife to adjust its size as needed. Then, simply slide the 9mm - thick filter into your'standard' solder smoke filter slot. When you're doing soldering, turn on your smoke - absorbing equipment with the filter in place, and it will start to absorb the solder smoke. As for maintenance, check the filter regularly. If it becomes clogged or loses its effectiveness in absorbing smoke, it's time to replace it. Keep it in a dry place when not in use to ensure its longevity.
