Wool carpets on hardwood floors. I see plenty of dust outside (construction?) but very little in the house. If I don't wipe the table for a week, I can't tell other than animal foot prints. I leave windows and doors open hours every day. At work the office seems about class 100k, but I guess the aircon system if filtering well enough. I don't doubt it's possible to create such an environment, but it's not "natural" or environmental other than in the sense of what you choose (as much as circumstances let you) to live in.
