I have 4 Festool vacs and a Felder RL160 coupled to my stationary machines, yet I have 2 Jet filters running (the larger one all day, the smaller one above the work bench when I'm sanding by hand)

You'd think I wouldn't need any since all my stuff is professionally coupled to quality DC destined for closed indoor use, but you'd be surprised at the junk you have to blow off every few weeks from the filters. The larger one was down for a few weeks, I really felt the difference in air quality as airborne dust just accumulates over the work hours.

Also for over a year now I exclusively use active charcoal filters on them, lots of rubbish is emitted by some of the products you have to use, and by the panel materials such as formaldehyde. Those filters also take care of that. (We live above the shop and had a baby this year, so I started being extra careful since the pregnancy)

WOW, thanks guys.
I was hoping for advice like this since you have experienced the benefits in your own shops.
So I will take advantage of the sale today and pick one up.
I thought the response would be;  get one since it’s good for your health, but I didn’t imagine the amount of “stuff” that Yous guys say is found in the filters.
Thanks again,
Scott

I hung one in a basement shop last week. We noticed an immediate reduction in the amount of particulate you could see in the afternoon sunshine. Good investment in your health.
