12 Pack Activated Carbon Filter Replacement Refills for KOTTO Solder Smoke Absorber Fume Ventilation Extractor, Compatible with DIY Fume Extractor with 4.7"*4.7" Fan Unit

Seems to work just as advertised

This machine worked well for when my husband does wood carving in the basement

Works

Just received the fume filter and tried it out. As the videos demonstrated, the air flow gathers solder flux fumes horizontally from 1+ feet away and the charcoal filter seems to gather everything. I’m happy with the solid construction also.

Good, fits perfectly and cuts down on chemical smells

I got these for replacement filters for my KOTTO fume extractor and they fit perfect! I wanted to make sure I had a good supply of these filters for the future and didn't want to worry about availability down the road. There isn't much else to say, they fit my extractor, they work great at filtering the solder fumes, and they're inexpensive. I highly recommend these!

These Activated Carbon solder air filters are thick and are a nice replacement. I wish I found these long ago, 12 for $19 is an insane deal. Many other filters are more expensive, but are the same as these. These are actually good filters and 12 will last me a very long time. These are about 12mm thick and each one comes sealed in it's own plastic bag to keep dust out and keep it fresh until you need it. I was really glad they came individually packaged as a zip bag doesn't work well with carbon filters. They are exactly as described and shown in the listing.

We all know we're supposed to change these activated carbon filters VERY frequently when in use - they get used up just from exposure to the air in a matter of days. Thus I really liked this 12 pack at a good price. I double and triple checked the measurements and sure enough, they are a close enough fit for my ValtCan TS:500 that I can use them with no real issues.
