Well, like you said, it s not efficient. You can take in air for the AC from anywhere with custom ductwork. The advantage of a closed system is that you are recirculating cooler air that s already been dehumidified. With an open system, you ll be cooling/dehumidifying outside air, so the cost to operate is going to be significantly higher.

I can appreciate your not wanting to be changing filters all the time, but is it possible to construct a multi-stage filter with a large, cheap fiberglass first stage filter that could be taken off and knocked clean? You could then taper down to a pleated filter to keep the AC innards clean.

This was my thought as well.

Mini-splits are great, I use one in my shop. But, he’s wanting to ventilate and not recirculate to avoid filtering.

However, by running a room filter (like a Jet), you won’t get much dust in a mini-split. But then you do have to clean the room filter. I think that’s what he is wanting to avoid.
