When the temperature calls for below-freezing temperatures, do more than bundle up: detox. Lay a plastic tarp outside and put items that are next to impossible to launder -- like throw pillows, sofa cushions, children's plush toys and even comforters -- on top. Let these items sit there for as long as possible (about eight hours) to let the deep freeze clean them for you. Dust mites and odor that may have built up will literally be frozen to death. When you bring them back inside, they'll be fresher and cleaner.

Fall is a good time to cross-ventilate a room to flush out toxins. The good thing about homes today is that they are built to be as energy efficient as possible, so they are as airtight as possible. The bad part? Chemicals are hard to get out of the house. To release and remove the chemical cocktail, open a window in the front of the house and one in the back. Then add table fans in front of each window, blowing the air out the window. You'll blow away the toxins!

If a room smells funny or has a strong odor, don't reach for scented candles, room sprays or plug-in air fresheners. Most fragrance products for rooms contain artificial scents and chemical phthalates that can be unhealthy to breathe in over time. The best smell is no smell at all, so try to find the source of the odor and remove it. Products like steam mops with nozzle attachments can help blast away dirt, grime and other debris and rid the room of any smells. If the room has a damp smell, try filling up a small bucket with rock salt (the stuff to de-ice driveways) and place it inside a larger bucket. It will draw in moisture over time and dehumidify the space naturally.
