Nesting & Air Filtering

I know that the nesting instinct is natural for pregnant women, but I don't like the term as it connotes inexplicable animal behavior. It's perfectly natural to see one's environment with newly critical eyes, in preparation for it being the home of a newborn human. It's also a sense of wanting clean before making a big mess... like cleaning up before a house party.

Anyway, among all the other cleaning (carpet, de-cluttering, dusting, etc.) the next thing to clean is the air. Hopefully this air filter will help to reduce the persistent dog smell that defies my attempts to extinguish it with weekly baths and carpet cleaning every 3-4 weeks. I even got a mini-model for the bedroom, which is relatively free of dogginess, but is probably where I spend the most time when home - 8 hours every day.
