Wen Air Filtration System 

got the smaller one, and I love it. frequency depends on what I'm doing but I've had it about 2 weeks. Orders extra filters but see you can "clean" them, may send back, lol. I'm looking for a pm2.5 sensor for automation purposes now. Only issue is it's RF and not IR, where there's a will there's a way!

I’ve been eyeing this unit for over a year, you just helped me make up my mind. Thanks Mike. BTW, how noisy is it?

Nice! I have been thinking about getting one for a while. You motivated me to order one. Unfortunately, it's on backorder.

I love mine had it a little over a year now

Hey Mike, that's a great addition to your shop. I've had mine about 18 months. It does a good job of clearing the airborne dust from sanding and the miter saw. I like the timer function, I can let it run for an hour or so after painting or glue ups.

Now that you have had the unit for a year, do you still like it and has it been trouble free? I have two Jet AFS-1000b's in my 420 sq ft (9' ceiling) shop that have now both failed (admittedly after good use, the first failed at 15 years and the second just recently at 19 years of hobbyist use - maybe 500 hours/yr). The new Jet 1000c units won't easily go in the same space, so I am looking at the WEN 1270 as a replacement, and I might only go with one as a single Jet did fine in cleaning the air at medium speed.

Congrats on the shop upgrade! I don't have one of those yet, but I do try to catch as much dust as possible at the source and invested in festool specifically because of how well the dust extraction is. I only have a festool vac, tracksaw and two sanders, but I've been very impressed with how little dust makes it outside of the vac.
