Aaron -
First, please always sign your name to every post. It is poor email
practice to do otherwise.
Second, are you talking about a ventilating system, which removes the air
from the room, or an air cleaning system, which cleans the air and
recirculates it? To my knowledge, Bailey Ceramic Supply is the only company
that manufactures and sells studio air cleaners specifically designed for
ceramic studios, with a serviceable HEPA filter. Most of the commercially
available ceiling-mounted air filters out there simply recirculate the air
and all the ultra-fine silica particles, which are the most harmful ones.
The Bailey systems are available in several sizes, and seem to be suitable
for home, institutional, or commercial studios. Check them out at

But you're right, the best thing is to wet-mop regularly, and of course to
simply avoid any indoor process or activity that makes dust unless there is
proper ventilatioin.
Good luck -

Hello, I work for a community art center just north of Philadelphia that
has a pretty decent ceramics program. We received a grant for ventilation
for our two studios and I am not sure what the best ventilation system is.
We are looking to remove the clay particulates from the air. I realize
that wet mopping is the best method for reducing clay dust, but what is a
good ventilation system for airborne particles?

There was a discussion on Clayart recently about air cleaners, and someone
quoted industrial testing which proved that the ionic air purifiers are
almost completely ineffective in the clay studio. I do not remember who
posted that message. Perhaps they will repost now.

Vince,
Thank you for your advice. My appologies for not signing. We are looking
for a particulate filtration system, not really a ventilation system. I
have the information from Bailey Ceramics Supply (their product I believe
is manufactured by Air King). I also just found some information about air
purifiers that generate "billions of negative ions which attract these
positively charged particles, regardless of their size (clay dust). These
particles clump together until they have sufficient weight to fall from the
air..." I am not sure how effective this system would be, who manufactures
it, etc. The article can be found at:

Once again, thank you for your input.

I would search the archives under
"purifier" and "air filter" maybe just filter would work.
1. My understanding is that ion generators don't work on clay dust or
silica.
2. Air filters may create more dust by keeping a breeze in the studio.
If there is a need for a dust removal system maybe:
1. The studio is not clean enough
2. There needs to be point source collection of dust.
3. Too many people in too small a space.
But just as a caution I am not an industrial hygienist and can barely
spell it. I would search fore professional help before investing in a
machine requiring a lifetime of maintenance/ filters/ air movement.

Hi Aaron,
I agree - create as little dust as possible.
Filtering clay dust is a difficult way to go - filters - especially the
ones fine enough to get out the fine silica - clog quickly. This means
constant cleaning and/or replacement.
Perhaps an air exchanger system would be the best and cheapest in the end.
They use the exhaust air to heat or cool fresh air coming in.
I don't know how expensive such a system would be but it would probably do
the best job of all they systems I can think of.
Worth looking into - especially if you already have heating and cooling ducts.

Hi Aaron,
Some negative ion generators produce ozone - not something you want to
breath too much of.
