It looks as though some of the media are back to looking at Santiasco in that light, whether it’s technically true or otherwise (there are so many candidates in Chile, including Coyhaique). But los que saben saben– atmospheric filth is no stranger to the basin. This message brought to you not as Schadenfreude but as a public service for those foolish enough to consider living there.
Those who have the means to read the Spanish-chilensis article, here:
Personally, I have a MouvAir filter unit for the considerable Patagonian dust, but that is a different story. There was a sale at kitchencenter.cl and I will plug them here since they have supplied a lot of good stuff for the house and at good sale prices. I have purchased things from them with better prices than even Amazon in the US could match. They are evidently into the drop-ship model and the savings that can be had there.
For Santiasco air I have found that an earlier generation M40 mask with a fresh Nuclear-Biological-Chemical (NBC) filter is often satisfactory.
