Plus a couple of air-to-air heat pumps that were installed back when the house was built in the late 70's.
Yes, compressor moving parts wear, but the resulting "fines" settle to the bottom of the reservoir and stay there.
Comparing a gasoline engine's oil contamination with a SEALED A/C system strike's me as a bit of a stretch....

The whole business seems like a stretch. The oil filter for AC is LOL-funny, but an interesting idea nonetheless.
The whole bit about the patent and "not selling" and all kinds of claims - I think that Porsche owners would be better served by going with someone who has been there for Porsche AC upgrades for a long time, and has a proven track record of excellent customer service.
Reid's sales pitch is, as the kids say these days, weaksauce.
