My shop is a 2 car garage. I usually work with the garage door open year round since I live in Southern California. I use a delta dust collector . My question is should I place a shop filtration system in such as the jet 1000 or is it really necessary? Please let me know your thoughts and reasoning behind your thoughts.

I have dust collection on most of the major tools (Band Saw, Table Saw, Planer, Thinckess Sander, table mounted routers) and all of the stationary sanding tools. I just built an air filter from a 20” box fan and 20” x 20” air filters. Hung it up high in the shop (I have high ceilings so it is 12’ off the floor) and WOW, it collects a lot of dust. I have it on the switch for the lights so it is on when I am in the shop and off when I leave. I am cleaning / changing the filter much more than I thought I would.

buy a Dylos DC1100. After running it the first time, you will know your answer. You will be surprised how much dust you generate and breath without knowing it.

gads Bernie – - buy a 200 dollar monitor? WHy not spend that money on the dust collection/purification instead?

North – key is collecting dust at the source. The dust collectors work and do collect a lot of dust in them, but the dust circulates for a long time before it is captured – - and most still settles on the shelves, and wood racks as well, as the box units don’t exchange enough air.
I have one and run it and change filters, but am not sure how much “better” the air is because of the box on the ceiling.

Every bit will help your lungs. I’ve been at this a long time. However be forewarned that those suckers make a lot of noise. I dd not think of this till I purchased my Delta and started using it. Great tool, but loud as a son of a gun.

DrDirt—A Dylos, or similar meter will let you know if your dust collection efforts are actually working… I put a LOT of time, and effort into collecting dust from my miter saw for example, and I am sure it is spewing nasty stuff, albeit far less than it was before.

A Dylos would let me know just how effective my dust control strategy is…

I just bought the jet with a remote control . I find it really does work well.I have also made one myself similar in design with two squirrel cage fans .I got all the filter stuff from ebay and it turned out good though I need help to fit it to the ceiling as it is heavier and therefore it will be a two man job. I expect it will work well also.They definitely remove harmful dust from the air.Alistair

Consider it if you want to work with the door shut.

If you truly can have the door open whenever your in the shop, a couple good fans would likely serve you just as well.

I’m definitely no expert on dust collection or the physics involved with air movement, but I read something a while back that made sense in my simple mind. It was pretty much summed up as dust not collected at the source has just as much chance of ending up in your lungs as it does in an air filtration unit.

I’m with Matt. If you have the door open, a fan behind you will do wonders. I always wear a dust mask as well.

Thank you for all of the great advise. It is appreciated. I think I may try a couple of fans and a dust max. It is always nice to get advise from others who nippy the craft.

Before you go getting a load of dust masks, Try out a cheap half facepiece respirator. 3M has some for around $25. They are much more comfortable and seems more effective to me. Mine is practically glued to my face anytime I am in the shop. I bet I wear that thing at least 60 to 70 percent of the time I am in the shop. Plus I’ve heard it fixes allergies too, if you have them. Just make sure to clean it out every once in a while.

North- Check out my page. I went through this issue and instead of buying one of these expensive units, I did a great DIY. Works great and filters my air perfect.

Gary – that is my experience – dust collection is very necessary, but I am not sure how much the ceiling unit is really helping.

That is in a closed room, it takes some time to clear the air…at the same time the fan is keeping dust that would otherwise settle, stirred up.

I liken the strategy that the purifier on the ceiling is kind of a lung.

I am not sure that if two people are in the shop, an argument that somehow your exposure is cut in half, because your partner already breathed in 1/2 the respirable dust.
Same with the purifier – just because it is catching dust, doesn’t mean your lungs aren’t filling with dirty air before the unit 10 feet up in the air cleans it. Hence to the OP – collection at the source is key…. I think trying to scrub the air, is not so efficient or effective, but I could be wrong.

Source collection and dust mask has been my route – blocking my lungs, rather than a passive filter on the ceiling clearing the air in a matter of hours. also why I have a shop fox tabletop downdraft table for sanding.
