I am remodeling part of my business space and would like to get some
opinions on heating and air cleaners.
I run a soils laboratory and have dust in the air constantly. I am
posting to this group because of the similarity to the dusty
environment with woodworking tools. I have a 800 sf cement slab with
block walls that I want to finish with insulation, drywall and vinyl
tile floor.

The way I see it I have 2 options:

I was considering going with a suspended slab PEX radiant floor heat
system and having a constant exhaust system to remove any dust from the
air. If I went with forced air heat then all my hot air would be
evacuated. I assume the exhaust would not remove the heat in the room
generated from the floor.

Or

Use forced air and commercial duty air cleaners to recycle the internal
air. But I don't want a high dB cleaner running constantly.

Any opinions or experience with this combination of heating and air
cleaning?
Thanks in advance

1) If you are exhausting internal air, there has to be outside air coming
in to make up what is exhausted. It will take the heat out of the room
regardless of how it is generated since you will be replacing the heated air
with cooler, outside air.

2) No experience with the ceiling mounted air cleaning system but I do have
a central ac/heat in my shop. The filter gets clogged in very little time
so I don't usually run the ac/heat when I'm creating dust. I may run the
heater just to take the chill off before starting to make dust but haven't
needed to this year here in Phoenix.
