Over the years, I’ve had had various window units in my shop. All of them had dust fines bypass the screen filters and eventually cause the units to lose efficiency. I’ve thought about different type AC units, but I’d expect they’d all suffer from the same problem, since they all have filters and pull air from the shop. Surely some of you folks have encountered and solved the problem. Please tell me how you did it.

Just to say it, I have HEPA filtered dust control on all power tools and a Jet ceiling mounted air cleaner. But there are still fines floating about in the shop. Can’t see them, but the AC sure collects them. It’s a slow process, but I can’t stop it.

Perhaps you can build an intake filter for the AC unit. You have to be careful not to restrict the airflow too much. Keep in mind that you are NOT restricted to the intake area of the AC unit. You could effectively duct it to a much larger area. The larger the total air filter area, the less air restriction it creates.

A simple example would be to butt a box up against the AC intake. One side is up against the AC unit, the other 5 sides could each have filters on them.

Of course, other styles of filters could be used. For example duct to a large pleated filter. But I’m thinking something simple, inexpensive, that you could use common HVAC filters on.

The other thing is just to make cleaning out the AC unit part of regular maintenance.
