I have an opportunity to create a woodshop in a basement -- but, upon being
asked to do so, I was very hesitant to reply due to fear of creating a more
dust in her home. Question: Is more dust upstairs a given with a basement
shop? Or, can I effectively whip that problem? My tools are currently in
storage and among them is a 1200 cu ft (advertised) DC. I used it in my
last shop with the bags that came with it, and dust *was* a problem --
particularly with MDF. If I can figure a way to *effectively* whip this
dust issue, I can have a great shop in the basement.

It sounds as though your collector is collecting but the
bags are forcing it back into the atmosphere and the fine
stuff is what you are having to deal with. Maybe you would
be best off with a blower/filter (box fan with a furnace
filter) to pick up the real fine stuff and separate it from
the breathable stuff.
I don't have a dust collector hooked up and dust isn't a
problem because I typically clean up a couple of times a
day. Hey, you've got to do something while you're waiting
on the glue to dry. I do use a shop vac with my whirly
sander which makes a huge difference otherwise it's mainly

Do you know what kind of bags you have on your DC? You really want to get
good bags as the ones that come with most collectors will let too much fine
dust through them. Then you want to be sure you have it hooked up to all of
your tools so you can collect as much dust as possible at the source. You
could build (easy to do) or buy an air filtration unit that will catch some
of the dust that floats around the shop. Seal up all the air gaps between
walls, floors, etc so the remaining dust can't easily find it's way
upstairs. Make sure you have a door that does a good job of sealing your
shop from the rest of the house. Buy a good door mat to wipe your feet when
leaving the shop. I don't think you'll have much of a dust problem.

Also run negative presure in the shop. Do this by adding a vent fan
through an outside wall. Then suck air from the shop and blow it
outside. This way if there are any air leaks between the house an the
shop the air will move from the hounse into the shop. No dust flow into
the house from the shop.
So I see three parts.
1) Dust collector - it just catches the big pieces. Dust still passes
through the bags and very fine dust will excape that way. You will also
get larger dust particles because the DC won't get everything from the
2) Add a Air filtration unit. This will catch the finer dust particles
that float in the air. A broom will get the ones large enough to fall
out of the air. By the way. A good place to look for high air filters
is the used market for restraunt and bars. There are places that are
outlawing smoking inside. Bars in these areas used to have air filters
to clean the smoke out of the air. These should work great in the shop.

routers, a shaper, etc. etc., with lots of dust collection. Unless I
stop and clean up every few minutes there's lots of dust.
Normally I cut several sheets of plywood, MDF, or particle board at a
time, with 30+ cuts per sheet (yes, I make mostly small things). In
other words, lots of cuts, lots of routing, lots of shaping, lots of dust.
The only problem with dust I have had outside of my shop is from the sawdust
that settles on my shoes. I put a door sweep on my shop door to help keep
the dust out of the rest of the basement and it seems to work well. Make
sure you don't have a cold air return in your shop so the dust won't get
into your furnace. I don't have a dust collector but I do try to vacuum the
shop when I'm through for the day. I second the suggestion someone had about
getting an air filtration unit. I just got one and it really helps the air
in my shop. Not so much dust settling everywhere. I'm sure that would solve
any dust problems you might encounter.
If the home is heated with central forced air, usually this system also
heats the basement so the air would be re-circulated throughout the house.
This would be a VERY big concern as the furnace filters would not trap the
fine dust! If there is a separate heating system and no air circulation
between basement and the remainder of the living areas, it would be less of

My furnace is in my shop (in the basement) and I've found no
difference in the amount of dust in my home. I do have a DC, but I
didn't use to. I do change the furnace filter quite often, however,
usually after each project I do.
I have a basement shop located in the furnace room with central forced
air and a gas water heater. There are no heat vents or air returns in
the shop since the furnace and uninsulated duct work and being
underground keep it a pretty constant 65-70C. I don't have any problem
with dust escaping the shop into the rest of the house. This may be due
to the negative pressure created by the gas furnace and water heater
constantly venting air from the room. I use duct tape to cover the
gaps in the furnace filter slot so that shop dust doesn't enter the
return air system of the house.
I just got a Delta AP100 Ambient air cleaner at Lowes for $200. It's a
funny looking shape for a air cleaner, a triangle, But it works great. I
have a small basement shop 15 x 12 and it really sucks up the floating dust.
450 cfms. I was looking at some other models when I came across this one.
What I like about it is that it has a Light in the bottom, so it's like two
birds with one stone. I 've currently reconfiguring my shop. Last night I
was cutting a lot of MDF and Hardbord for a new Miter station, dust
everywhere. So I flipped on the filter and away it went. I highly recomend
I don't have a problem with dust upstairs. However, I keep a piece of scrap
over the furnace filter slot. Also, I sweep & vacuum after nearly all visits
to the shop when I make a mess.
Good luck & have fun.

Yes. If you have and use a DC that will greatly help. An air cleaner
helps a lot too. Sawdust sometimes sticks to my clothes and I
sometimes forget to clean it off before leaving the basement. A
remote control on the DC really helps with using it often.

The best way to deal with no dust upstairs is to eliminate the dust in the
basement with a GOOD cyclone dust collector. I'm not talking about a
plastic gadget on top of a trash can. To get a good education on dust
collection in general, take a look at Bill Pentz's web site at
Bill has solved the dust problem with a very effective, high-air-volume,
cyclone dust collector design that has proven very effective in many
installations. Not only does the cyclone remove nearly all of even
the fine dust that is so probelmmatic, but by adding a good filter system
on the output that is certified down to 0.5 or 0.3 micron at well over
99% efficiency, you can nearly eliminate dust in the shop.
I am currently producing a kit version of Bill's cyclone design as
well as a blower housing to match. Info is on Bill's site at
