Hi there, So my birthday is coming up, and I asked my parents to get me The Jet AFS-400 for a present.
I was just wondering if any of you guys have this air Filtration system, and what are the PROS, & CONS
Do you like it?, or hate it, or it’s just is junk????

Thanks, Michael Frey

I really don’t have much of an opinion on the brand because I’ve never been in the market for one. My shop is so small that I’d bump my head on it every time I turned around. But I think it’s a good idea for you to get started off on the right foot at you’re age so that you can enjoy a long life with clear lungs. I do like JET stuff ok – I have a JET bandsaw. Happy woodworking!

If your going to get a air Filtration system find one that you can find replacement filters easy. It seems the filters on this is hard to find.

I’ve been looking for an air filter for a small shop and am also thinking about at the AFS-400.
The AFS-1000B seems to be popular, and was well-rated by FWW, but is pretty large for the
small space I have available. The AFS-400 seems comparable in filtration, but smaller (and
thus lower CFM).

McFeely’s lists filters for the AFS-400, and you should be able to order filters for it directly from
WMH tool group. However, it would be nice to be able to walk into a Woodcraft or Rockler store and
pick one up.

As for “new” [sic], the AFS-400 seems to have been around for about 2 years now, so I would expect
more retailers to carry it and supplies for it than I am seeing.

I have the AFS-1000B and it works well. I would make sure you have a regular dust collector and ways to regulate dust at every piece of equipment before you get this. I use it sometimes, but my actual dust collector and shop vac are a lot more valuable.

Not to be a d!ck but, it is Jet’s new not “Jets knew” in your title

The AFS-1000B definitely has better specs than the AFS-400.
It has about a 2.5x advantage in CFM with the same filtering level
for just 1.5x the (normal) price. On sale, it is an even better deal.
So, if you have room/need for the AFS-1000B, it should be a better

My local Woodcraft contact says that it will be on sale next week, but check with
your local store. I don’t know that they are all on the same schedule.

I can’t speak to the construction of the AFS-400, as I have never actually seen one.

I agree with Jason about the dust collector. However, I can almost always find some
way to use my saw that makes it send dust somewhere other than into my collector
system, so I think of an air filter as necessary equipment.
