looking at getting one of those airborne shop filters. are they any good? I know Delta has one….any other makes I should know about.
I rip lots of MDF with my shop vac attached to table saw, which works fairly well. also making lots cross cuts on SCMS. breathing is not a concern as I wear mask for brief cutting and respirator for continuous ripping, mainly I want to alleviate some or (hopefully most) of the airborne dust that floats around and settles on all the stored stuff in my garage.

Mine is a Woodtek from Woodworker's Supply. It is probably as good as any. They are all just squirrel cage fans drawing your air through a series of filters.
Mine has a wireless remote switch, which is a must, IMHO. It is suspended from the ceiling.
Yes, they work, and MDF work will make them work even harder.
Try almost any brand . . . they cannot be that different. If it was me shopping, I would look for an Amazon deal with free freight.
Thanks Gene....Never done Amozon..but maybe I should try it out.
Also just saw someone posted simular question in general. Idea was brought up for afixing an extra filter, sounds like that may be a good idea.
Buy yourself a small box or window fan. Make a plywood box for it that accepts furnace filters. Try to get a large filter area vs the fan size, so that airspeed is relatively low and the filter can be more effective.
happy?
Hey...that sounds cool! did you make one?
small fan is better? is the box wide open on the end opposite the filter? should I have one filter or would it be good to have more than one filter? does the fan need to be sealed on sides and top to get maximum flow from the filter or do you simply sit it in the box?
I like this idea as I gotta watch the dough flow, plus anything you can build yourself is cool. but I definately need something.
I've never built this specifically, but I do have something similar that's used as an equipment rack in the garage. Used to have some computer gear in it, but now just a cable modem and router. Fan on top, filter on the bottom in my case (so most dust would fall downward and never even reach the filter), since I wasn't clearing the air so much as keeping the equipment clean and cool.The size of the fan depends on how much air you think you need to move -- more air filters more volume, of course, and helps equalize the temp, but will stir up dust more, and blow papers around, etc. Much below about 12" diameter probably won't do much, and much bigger than 24" gets to be a big box and a lot of breeze.You want to seal the fan to the box reasonably well, just to maximize effect. (Make the fan blowing out, of course.) Filter size depends on how big you want to make the box -- the bigger relative to fan size the slower the airflow through the filters and the better they work. At least equal to the area of the fan opening, I'd say, and maybe 2-3x ideally. Filter quality depends on what you want to spend, but I'd suggest the cheapest pleated paper units.You can build a cheapie version of this with just a cardboard box and some duct tape, and of course a fan and filter.
If ignorance is bliss why aren't more people
happy?
Just finished box. found window fan for $30 CDN. put in double filter, one 98 cent mesh type followed by a $12.00 pleated filter. I put in a duct at the back so that I could have it vent out of the garage instead of blowing around if I want to.box is 24"x24"x 15"high.
The only thing I'm questioning aboput my design is the exhaust end(or outflow end) I put in a duct for the venting option, because someone in a simimlar thread in general mentioned about blowing the dust around being a problem from the exhaust end. But I'm wondering if because the flow of air out the back hits the back side for most of the area before exiting the 4" duct. the backflow for circling of air may hinder the inflow of air.
I was thinking perhaps I should shape the back of the box so that the air is directed at the 4"opening. what do you think.
